The formula sets itself apart from conventional multivitamins by including a complex of digestive enzymes—Bromelain, Papain, and Lactase—specifically added to improve the digestion and absorption of the nutrients in the capsule, ensuring that the body effectively uses what it ingests and does not merely excrete it. With doses equal to or greater than 100% of the Nutrient Reference Values (NRV) for most essential vitamins and minerals, including a particularly high dose of Vitamin C (\u003e1390 mg per serving), Multi-V comprehensively covers the micronutrient needs of athletes, active individuals, and anyone looking to fill nutritional gaps in their diet. Vegan, gluten-free, soy-free, and no added sugars.

For athletes and individuals with high training volumes, micronutrient needs are often higher than those of the general population due to increased energy metabolism, higher free radical production, sweat losses, and increased cell turnover. A full-spectrum multivitamin provides a nutritional safety net that ensures the normal functioning of all physiological processes dependent on micronutrients, from energy metabolism to immune function, protein synthesis, and bone health.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHigh-dose Vitamin C (\u003e1390 mg) for immunity and antioxidation:\u003c\/strong\u003e The dose of Vitamin C in Multi-V is significantly higher than the standard dose in conventional multivitamins (typically 80 mg), approaching the high-dose supplementation protocols used in contexts of intensive immune support and antioxidant protection during periods of high-intensity training. Vitamin C is proven to contribute to the normal functioning of the immune system, the protection of cells from oxidative stress, normal collagen formation, and the reduction of tiredness and fatigue, being especially relevant for athletes with high training volumes or during periods of increased exposure to pathogens.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDigestive enzyme complex (Bromelain, Papain, and Lactase) for optimized absorption:\u003c\/strong\u003e The most significant differentiator of Multi-V compared to standard multivitamins is the inclusion of a complex of three digestive enzymes. Bromelain (extracted from pineapple) and Papain (extracted from papaya) are proteases that facilitate protein digestion and contribute to the integrity of the gastrointestinal mucosa. Lactase is the enzyme responsible for digesting lactose, making the product suitable for people with lactose intolerance. The inclusion of these enzymes in the same capsule as the micronutrients increases the bioavailability of the vitamins and minerals present, which depend on adequate digestive function to be effectively absorbed, especially in contexts of compromised digestion due to diet, stress, or frequent use of anti-inflammatories.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eConvenient and practical: 1 capsule per day:\u003c\/strong\u003e Unlike many multivitamins that require 2 to 4 capsules daily, Multi-V concentrates the entire formula into a single daily capsule taken with breakfast, eliminating the need for multiple doses throughout the day and facilitating long-term adherence.

The prevalence of magnesium deficiency is high in the general European population (it is estimated that 10 to 30% of the population has an intake below the reference dose) and even higher in athletes — intense exercise significantly increases magnesium losses through urine and sweat, and magnesium is used in greater quantities during ATP synthesis and muscle contraction.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMagnesium bisglycinate: the form with the highest bioavailability and least gastrointestinal irritation:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOf the multiple forms of magnesium available on the supplement market, \u003cstrong\u003emagnesium bisglycinate\u003c\/strong\u003e (magnesium chelate with two glycine amino acids, also called magnesium glycinate or diglycinate) is consistently the form with the highest documented oral bioavailability and the lowest risk of laxative effects. The mechanism is as follows: free ionic magnesium (Mg²⁺) in the intestine competes with other minerals (calcium, zinc, iron) for intestinal divalent metal transporters (DMT1), and in excess causes osmotic irritation of the intestinal mucosa (a laxative effect characteristic of magnesium oxide and magnesium sulfate). In bisglycinate, Mg²⁺ is chelated (covalently bound) to two glycine amino acids, forming a neutral and small complex that is preferentially absorbed by the PEPT1 and PEPT2 peptide transporters of the intestinal epithelium — the same transporters used to absorb di- and tripeptides from protein digestion — efficiently and without competition from other minerals. The study by Schuette et al. documented that magnesium bisglycinate has superior intestinal absorption to magnesium oxide (the cheapest and most common form in magnesium supplements on the market, but also the one with the lowest bioavailability, with only 4% absorption).

During muscle contraction, Ca²⁺ is released from the sarcoplasmic reticulum into the myocyte cytoplasm, binding to troponin C and activating the actin-myosin complex. Muscle relaxation requires the reuptake of Ca²⁺ by the sarcoplasmic reticulum via SERCA (sarcoplasmic reticulum Ca²⁺-ATPase), a process dependent on ATP and magnesium as an ATPase cofactor.

In K2 deficiency, MGP remains uncarboxylated (dp-ucMGP, desphospho-uncarboxylated MGP) and is inactive — it does not inhibit arterial calcification. The proportion of dp-ucMGP in the blood is the most sensitive and specific biomarker of vitamin K2 status in vascular tissues, and high levels of dp-ucMGP are associated with greater coronary calcification and higher cardiovascular risk. The Rotterdam study by Geleijnse et al.

Without sufficient vitamin C, collagen synthesis stops — prolyl and lysyl hydroxylases become inactive because vitamin C is needed to re-reduce the catalytic Fe²⁺ ion of these enzymes (oxidised to Fe³⁺ during the reaction) back to the active state. Collagen is the most abundant protein in the human body (~30% of total protein) and the structural component of tendons, ligaments, cartilage, skin, bone, vascular wall, and cornea — the entire structural integrity of connective tissue depends on continuous collagen synthesis.

Magnesium directly improves sleep quality by promoting GABAergic activity (relaxation) and antagonizing NMDA receptors (reducing neuronal hyperexcitability), increasing time in deep sleep. Zinc supports melatonin production (it is a cofactor for arylalkylamine N-acetyltransferase, AANAT, the rate-limiting enzyme for melatonin synthesis in the pineal gland). The recommendation to take ZMA \u003cstrong\u003eon an empty stomach or away from calcium-containing foods\u003c\/strong\u003e is based on the observation that calcium competitively inhibits the intestinal absorption of zinc and magnesium by DMT1 transporters — milk, dairy products, and calcium supplements taken simultaneously significantly reduce the effective absorption of ZMA.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eUsage\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eRecommended dose:\u003c\/strong\u003e Take before bed, on an empty stomach or at least 1 to 2 hours after your last meal (especially away from calcium-rich foods — milk, cheese, yogurt — and calcium supplements).

In fish oil, EPA and DHA are esterified in \u003cstrong\u003etriglycerides\u003c\/strong\u003e (TG): to be absorbed, TGs need to be hydrolyzed by pancreatic lipase in the intestinal lumen into free fatty acids and monoglycerides before forming micelles with bile salts and being absorbed by enterocytes.

Comparative studies have documented that the bioavailability of EPA and DHA from krill is 10 to 15% higher than that of fish oil in the TG form when assessed by the erythrocyte omega-3 index (a validated method for evaluating omega-3 status in tissues). A practical consequence of this difference is that krill oil does not cause the usual \"fish burp\" associated with fish oil, as phospholipids are absorbed more proximally in the small intestine, and there is less free EPA and DHA in the lower intestine to be fermented.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e400 mg of phospholipids: the structural component of cell membranes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKrill phospholipids\u003c\/strong\u003e (400 mg\/capsule in Super Krill) are mainly \u003cstrong\u003ephosphatidylcholine (PC)\u003c\/strong\u003e and \u003cstrong\u003ephosphatidylethanolamine (PE)\u003c\/strong\u003e with EPA and DHA esterified at the sn-2 positions of their glycerol backbones. In addition to serving as a transport vehicle for EPA and DHA, krill phospholipids have their own functions in cell membranes: phosphatidylcholine is the most abundant phospholipid in plasma membranes and lipoprotein membranes (HDL, LDL, VLDL), and is also a direct source of \u003cstrong\u003echoline\u003c\/strong\u003e (the phosphocholine group of PC is hydrolyzed in the intestine, releasing free choline that can be absorbed and used in acetylcholine synthesis and methylation).

Krill is one of the richest natural dietary sources of astaxanthin, which is the main component responsible for the red color of krill oil. Astaxanthin has exceptionally potent antioxidant properties that distinguish it from other carotenoids: unlike beta-carotene and lycopene (which have antioxidant activity on only one side of the membrane), astaxanthin has a molecular structure that spans the entire phospholipid bilayer, with its polar hydroxyl groups at the ends anchoring it to the outer and inner interfaces of the membrane, and the conjugated double bond chain in the hydrophobic interior acting as a free radical scavenger throughout the thickness of the membrane. This unique geometry gives astaxanthin an antioxidant activity 10 times higher than beta-carotene, 550 times higher than vitamin E (alpha-tocopherol), and 6000 times higher than vitamin C in singlet oxygen quenching assays. EFSA recognizes astaxanthin as contributing to the protection of cells from oxidative stress. In addition to its antioxidant activity, astaxanthin has documented anti-inflammatory effects (NF-κB and COX-2 inhibition), neuroprotective effects (crosses the blood-brain barrier), and retinal protection (accumulates in the macula and protects photoreceptors from photo-oxidative damage).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCardiovascular health: the synergistic effect of EPA\/DHA + phospholipids + astaxanthin:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eKrill oil has a cardiovascular effect resulting from the synergy of three components: EPA and DHA (with the effects already described in the \u003cstrong\u003eOmega 3\u003c\/strong\u003e section — triglyceride reduction, modulation of platelet aggregation, anti-inflammatory effect via resolvins); phospholipids (which support the integrity of erythrocyte and endothelial cell membranes and play a role in regulating HDL-cholesterol via lecithin-cholesterol acyltransferase, LCAT); and astaxanthin (which protects LDL from oxidation — the critical step in atherosclerotic plaque formation, as described in the \u003cstrong\u003eVitamin E\u003c\/strong\u003e section).

(1987), published in Agents and Actions, documented that zinc picolinate raised Zinc levels in hair, erythrocytes and leukocytes significantly more than zinc acetate or zinc citrate at the same dose, being considered the foundational study for the use of zinc picolinate as a highly bioavailable supplement.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eZinc: more than 10 EFSA-approved health claims covering all major physiological systems:\u003c\/strong\u003e Zinc is the trace element with the highest number of EFSA-approved health claims for any supplemental mineral.

The widespread use of sunscreen (which blocks UVB), the tendency to remain indoors (office work, commuting by car), and clothing coverage that limits skin exposure to the sun throughout the year drastically reduce cutaneous synthesis even in months of higher radiation. On the other hand, Vitamin D is scarce in food: the main dietary sources are fatty fish (salmon, tuna, sardines), eggs, and fortified dairy products, but in quantities that rarely cover daily needs without supplementation.

Suspending cholecalciferol in a lipid oil (in this case, safflower oil) ensures that the vitamin is pre-dissolved in a lipid matrix that immediately facilitates its incorporation into micelles, regardless of the fat content of the meal with which it is taken. HSN justifies the choice of safflower oil specifically over other alternatives: water degrades cholecalciferol over time; alcohol evaporates and creates stability problems; olive oil has an intense taste that can be unpleasant and degrades more quickly; safflower oil is stable at room temperature (does not solidify in winter, unlike some oils), colorless, has no perceptible taste, has good oxidative stability, and does not easily peroxidize.

The meta-analysis by Tripkovic et al.

After oral ingestion, cholecalciferol is absorbed in the small intestine with the help of lipid micelles formed by fatty acids from flaxseed oil, transported to the liver where it is converted into 25(OH)D (calcidiol, the storage form and analytical marker), and subsequently converted in the kidneys (and in other peripheral tissues) into the active form 1,25-dihydroxyvitamin D (calcitriol), which exerts its effects through nuclear VDR (Vitamin D Receptor) receptors present in almost all cell types in the body.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVitamin D deficiency in Portugal and Europe: prevalence, structural causes and health impact:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDespite Portugal having one of the best sun exposure conditions in Western Europe, studies on the prevalence of Vitamin D deficiency in Portuguese adults reveal worrying values: studies conducted in the adult Portuguese population document that 30 to 50% of adults have 25(OH)D levels below 50 nmol\/L (20 ng\/ml) during autumn and winter months, and a significant proportion maintain insufficient levels even during summer months. The structural causes are common to all modern Europe: indoor work environments with minimal sun exposure during working hours, widespread use of sunscreen during months of higher insolation, increasing preference for indoor activities, and a dietary pattern where food sources rich in Vitamin D (fatty fish, egg yolk, fortified dairy products) are not consumed in sufficient quantity to cover daily needs. The consequences of chronic Vitamin D deficiency are multisystemic: increased risk of osteoporosis and fractures (via reduced intestinal calcium absorption), increased susceptibility to respiratory infections (Vitamin D modulates innate immunity by inducing antimicrobial peptides such as cathelicidin), muscle weakness and pain, and an epidemiological association with increased risk of autoimmune, cardiovascular, and metabolic diseases.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMore than 10 EFSA health claims approved for Vitamin D:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe EFSA has approved health claims covering an exceptional physiological spectrum for Vitamin D: it contributes to normal absorption and utilisation of calcium and phosphorus; it contributes to normal blood calcium levels; it contributes to the maintenance of normal bones; it contributes to the maintenance of normal teeth; it contributes to normal muscle function; it contributes to the normal function of the immune system (in both adults and children); it plays a role in the process of cell division; and it helps to reduce the risk of falling associated with postural instability and muscle weakness in adults over 60.

The primary mechanism is \u003cstrong\u003eintrinsic factor (IF)-mediated absorption\u003c\/strong\u003e: dietary B12 binds to IF (a glycoprotein produced by gastric parietal cells), and the B12-IF complex is absorbed in cubilin receptors in the terminal ileum with a maximum capacity of ~1.5 µg per meal (regardless of the ingested dose). The secondary mechanism is \u003cstrong\u003epassive diffusion\u003c\/strong\u003e: about 1 to 2% of any ingested B12 dose is absorbed by passive diffusion along the entire intestinal mucosa, independent of IF, and this mechanism is proportional to the dose without saturation. At doses of 1000 µg, ~10 µg are absorbed by passive diffusion (1% × 1000 µg), in addition to ~1.5 µg via IF, totaling ~11.5 µg absorbed per dose. This is why international public health authorities recommend 1000 µg of cyanocobalamin 2x\/week as a supplementation regimen for vegans instead of smaller daily doses: high-dose passive diffusion absorption 2x\/week is more efficient and reproducible than relying exclusively on IF absorption at low daily doses, especially in people with reduced IF production (elderly, people with atrophic gastritis, post-bariatric surgery).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eThe functions of vitamin B12 in the body: the two B12-dependent enzymatic reactions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eVitamin B12 is a cofactor for only \u003cstrong\u003etwo enzymes\u003c\/strong\u003e in the human body, but both are absolutely essential.

Lipid peroxidation is a chain reaction initiated by free radicals (especially the hydroxyl radical, •OH) that attack the double bonds of membrane PUFAs, generating peroxyl radicals (ROO•) that propagate the chain reaction by autocatalytically oxidizing adjacent PUFAs. Alpha-tocopherol interrupts this chain by donating a hydrogen atom to the peroxyl radical (ROO• + alpha-tocopherol → ROOH + tocopheryl radical), converting itself into a tocopheryl radical (TocoO•) which is much less reactive and does not propagate the chain. The tocopheryl radical is subsequently regenerated by vitamin C (ascorbic acid) at the membrane\/cytoplasm interface, restoring active alpha-tocopherol in a vitamin E\/vitamin C antioxidant regeneration cycle.

In skeletal, cardiac, and smooth muscle contraction, Ca²⁺ released by the sarcoplasmic reticulum binds to troponin C and activates the actin-myosin complex (excitation-contraction coupling). In neuromuscular and synaptic transmission, the influx of Ca²⁺ through voltage-dependent calcium channels triggers the exocytosis of synaptic vesicles. In the blood coagulation cascade, Ca²⁺ is an essential cofactor for multiple coagulation factors. EFSA has approved health claims for calcium regarding its contribution to normal bone and tooth development and maintenance, normal muscle function, normal nerve transmission, normal digestive function, and normal blood coagulation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePrevention of muscle cramps during exercise:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOne of the most valued applications by the sports public is the prevention of \u003cstrong\u003emuscle cramps\u003c\/strong\u003e during and after exercise.

Its inclusion in the formula is essential to ensure the stability of the oils throughout the product's shelf life.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eThe omega 3\/omega 6 ratio in the Western diet: why combined supplementation is relevant:\u003c\/strong\u003e The contemporary Western diet has an omega 6\/omega 3 ratio typically between 15:1 and 20:1, much higher than the 1:1 to 4:1 ratio that researchers associate with lower chronic inflammation and lower cardiovascular risk. This imbalance results from the very high consumption of vegetable oils rich in linoleic acid (soy, sunflower, corn, which predominate in processed foods) and low intake of fatty fish. Excess omega 6 (especially linoleic acid) competes with omega 3 for the same delta-6-desaturase enzyme, reducing the endogenous synthesis of EPA and DHA from ALA. HSN's Omega 3-6-9 1000 mg helps increase the intake of EPA and DHA (the most biologically active long-chain omega 3s) and GLA (which, unlike linoleic acid, has preferentially anti-inflammatory effects).\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eUsage\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eRecommended dose:\u003c\/strong\u003e Take 1 softgel twice a day with meals (total: 2 softgels\/day).

In most modern Western diets, with an omega-6\/omega-3 ratio of 15:1 to 20:1 (compared to the evolutionarily adequate ratio of 1:1 to 4:1), the competition of omega-6 fatty acids for enzymatic elongation almost completely suppresses the conversion of ALA to EPA and DHA, making direct intake of EPA and DHA (via fatty fish or supplementation) indispensable to maintain adequate plasma and tissue levels. EFSA has approved specific health claims for EPA and DHA: they contribute to the normal function of the heart (from 250 mg\/day of EPA+DHA); DHA contributes to the maintenance of normal brain function and normal vision (from 250 mg\/day of DHA); DHA contributes to the normal brain and visual development in fetuses and breastfed infants (via maternal intake); and high doses (3 g\/day of EPA+DHA) contribute to normal blood triglyceride levels.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTriglyceride (TG) form vs. ethyl ester (EE): the bioavailability difference that justifies the choice:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNatural fish oil contains EPA and DHA in triglyceride (TG) form, which is the physiological form in which fatty acids exist in all animal tissues.

Ethyl esters have documented lower bioavailability than triglycerides: a classic comparative study by Dyerberg et al. (2010) documented that triglycerides have 124% bioavailability compared to 91% for ethyl esters when consumed with a fatty meal, and that ethyl esters have almost zero bioavailability on an empty stomach (unlike TGs which are absorbed even without co-ingestion of dietary fat).

Supplements that pass all criteria receive a 5-star IFOS rating, which is the most internationally recognized certificate for fish oil. The importance of this certification is particularly relevant given that market studies document that a significant proportion of fish oil supplements sold without independent certification contain lower EPA+DHA levels than declared on the label, or show oxidation indices (peroxide, totox) that indicate the oil is rancid, which reduces bioavailability and can have adverse effects (oxidized lipids are potentially pro-inflammatory).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eEPA: the systemic anti-inflammatory and cardiovascular protective fatty acid:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEPA (eicosapentaenoic acid) is the precursor of series 3 eicosanoids with anti-inflammatory activity: prostaglandins E3 (PGE3, with anti-inflammatory and vasodilatory activity), thromboxane A3 (TXA3, with less vasoconstrictor and antiplatelet activity than TXA2 derived from arachidonic acid) and leukotrienes B5 (LTB5, with less pro-inflammatory activity than LTB4 derived from AA).

The dose of 1000mg\/day (2 doses of 500mg) recommended by HSN is well above the minimum dose for deficiency prevention (60 to 80mg\/day) but within the window of documented maximum benefits for the athletic and general adult population.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePowder format vs. capsules: the practical advantages of Ascorbic Acid Powder:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe powder format of Vitamin C has specific advantages over the capsule or tablet format. \u003cstrong\u003eFractionated absorption throughout the day\u003c\/strong\u003e is more efficient for Vitamin C: being water-soluble, its intestinal absorption is saturable above ~200 to 500mg per dose (the absorption percentage progressively decreases with increasing dose). The powder format allows easily dividing the daily dose of 1000mg into 2 to 4 intakes throughout the day (e.g., 250mg 4x\/day or 500mg 2x\/day), maximising total absorption. The powder format is also ideal for athletes who prepare sports drinks, smoothies or shakes where Vitamin C can be incorporated without the need to swallow additional capsules — just add the powder scoop to a post-workout protein shake or fruit juice.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eIntense acidic taste: the organoleptic property of pure ascorbic acid:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAscorbic acid has an \u003cstrong\u003eintense acidic taste\u003c\/strong\u003e (similar to concentrated lemon juice) which is its most characteristic organoleptic property. For maximum palatability, HSN recommends dissolving in 100 to 200ml of water or fruit juice (which softens the acidity with natural fruit sugars) and consuming quickly to minimise acidic contact with tooth enamel. People with dental sensitivity to acid may prefer buffered forms of Vitamin C (calcium ascorbate or sodium ascorbate, also available in HSN RawSeries) which have a neutral pH and do not cause enamel erosion.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVersatility of use: the base Vitamin C for any supplementation protocol:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAscorbic Acid Powder is the most versatile ingredient in HSN's portfolio for combination with other supplements: it can be added to any protein shake, isotonic drink, smoothie or juice to increase Vitamin C intake without significantly altering the taste (except for acidity) or interfering with the absorption of other ingredients.
