Conventional Vitamin D3 is obtained from sheep's wool lanolin, making it unsuitable for vegan diets. HSN uses Vitamin D3 from lichen, a symbiotic organism of non-animal origin, making the product 100% vegan. Dosage: 2 tablets 3 times a day before each meal (6 tablets\/day total). 120 tablets (20-day supply at full dose).\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eBenefits\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eThe essential trio for bone health: Calcium + Phosphorus + Vitamin D3 with Magnesium support:\u003c\/strong\u003e Bone health requires the synergistic action of multiple nutrients. Calcium is the most abundant mineral in the human body, with over 99% of the total body amount located in bones and teeth, where it constitutes the predominant structural mineral. Phosphorus, supplied by tricalcium phosphate simultaneously with Calcium, is the second most abundant mineral in bones, forming with Calcium the calcium hydroxyapatite [Ca₁₀(PO₄)₆(OH)₂], the mineral that gives mechanical strength to bone tissue. Magnesium, although present in a lower bone concentration (~1% of total body), is essential for the activity of osteoblasts (bone-forming cells) and for normal bone matrix mineralization. Vitamin D3 is the indispensable endocrine cofactor for intestinal Calcium absorption: without sufficient Vitamin D3, intestinal Calcium absorption drops from ~30-40% to only ~10-15%, making any Calcium supplementation much less effective in the absence of adequate Vitamin D3.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCalcium via tricalcium phosphate: high density of simultaneous Calcium and Phosphorus:\u003c\/strong\u003e Tricalcium phosphate is the calcium salt used as a source of the two most important minerals of the bone matrix (Calcium and Phosphorus) in a single molecule. It has a high percentage of elemental Calcium (~38.8% by weight of the salt) compared to calcium citrate (~21%) or calcium carbonate (~40%), with an intermediate bioavailability that is greatly improved by co-administration with Vitamin D3 (which is present in the formula). The daily dose provides 125% of the European NRV of Calcium (800 mg NRV; 125% = 1000 mg elemental Calcium), fully covering the daily calcium needs of healthy adults.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMagnesium Citrate: high bioavailability for the multiple physiological functions of Magnesium:\u003c\/strong\u003e Magnesium Citrate is one of the forms of Magnesium with the highest oral bioavailability, with studies documenting absorption 2 to 3 times higher than magnesium oxide (the cheapest and most common form). Magnesium has 8 EFSA-approved health claims, covering virtually all physiological systems: reduction of fatigue, electrolyte balance, energy metabolism, nervous system function, muscle function, protein synthesis, psychological function, and maintenance of normal bones and teeth. The inclusion of Magnesium in this formula is especially relevant because Magnesium is a cofactor of the enzyme 25-hydroxyvitamin D-1α-hydroxylase, responsible for the conversion of Vitamin D into calcidiol and calcitriol (the biologically active forms), making Magnesium essential for the functional activation of Vitamin D.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eLichen Vitamin D3: the only plant source of Vitamin D3, suitable for vegans:\u003c\/strong\u003e Vitamin D3 (cholecalciferol) is naturally produced in human skin by the action of solar UVB radiation and is found in animal-derived food sources (fish liver oils, fatty fish, egg yolk, dairy products). The conventional source of Vitamin D3 for supplementation is lanolin (sheep's wool wax), which is not vegan. Lichen is a symbiotic organism (alga + fungus) that produces Vitamin D3 through UVB exposure, being the only known plant source of Vitamin D3 currently commercially exploited for supplementation. HSN uses Vitamin D3 from lichen, making the product 100% suitable for vegan diets, unlike most Calcium + Vitamin D3 supplements available on the market. Lichen Vitamin D3 has bioavailability equivalent to that of animal origin in comparative pharmacokinetic studies.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eEFSA-approved health claims for Calcium, Magnesium, and Vitamin D3:\u003c\/strong\u003e The combination of the three nutrients in this formula covers a very complete set of EFSA-approved health claims, including: Calcium and Vitamin D are needed for the maintenance of normal bones and normal teeth; Vitamin D contributes to normal absorption\/utilisation of calcium and phosphorus; Vitamin D contributes to normal muscle function and immune function; Vitamin D and Calcium reduce the risk of falls associated with postural instability and muscle weakness in adults aged 60 years and over; Vitamin D and Calcium contribute to the reduction of bone mineral loss in post-menopausal women (low bone mineral density is a risk factor for osteoporotic fractures). This last statement is especially relevant for women over 50, where Calcium + Vitamin D supplementation is one of the nutraceutical interventions with the highest level of evidence for the prevention of osteoporotic fractures.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSupport for muscle function and cramp prevention:\u003c\/strong\u003e In addition to its role in bone health, Magnesium plays a critical role in normal muscle function, being the physiological antagonist of Calcium in regulating muscle contraction\/relaxation. Calcium promotes the contraction of muscle fibers, and Magnesium is necessary for subsequent relaxation (by competing with Calcium for binding sites on troponin and by activating Ca2+-ATPase pumps that remove Calcium from the cytoplasm). Magnesium deficiency results in neuromuscular hyperexcitability which clinically manifests as cramps, muscle spasms, and fasciculations. The combination of Calcium, Magnesium, and Vitamin D3 in this formula covers the three nutrients with the most relevance for integrated musculoskeletal health.\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 2 tablets 3 times a day before each meal (total: 6 tablets\/day).
