Each daily dose of 3 capsules provides 3000 mg of pure beta-alanine, within the dosage range most widely supported by scientific evidence (1600 to 6400 mg\/day) for the gradual saturation of carnosine in skeletal muscle and the improvement of performance in high-intensity exercise. The formula is minimalist: beta-alanine + magnesium stearate (anti-caking agent) + HPMC capsule. Vegan, clean label, manufactured in Spanish laboratories in compliance with European Union quality standards. 90 capsules per pack (30 daily doses). Dose: 3 capsules\/day, 2 before training and 1 at another time.\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\u003eBeta-alanine: the only muscle carnosine precursor with robust clinical evidence for improving performance in high-intensity exercise:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBeta-alanine is a non-essential amino acid (synthesized endogenously in the liver from ureidopropionate, a metabolite of uracil degradation) that functions as the main limiting factor for carnosine (beta-alanyl-L-histidine) synthesis in skeletal muscle. Carnosine is a dipeptide composed of beta-alanine and histidine, and the intracellular beta-alanine concentration is the rate-limiting step of its synthesis: even if histidine is available in abundance, the rate of carnosine synthesis is determined by the availability of beta-alanine. Oral beta-alanine supplementation increases plasma and muscle beta-alanine concentrations, which in turn stimulate carnosine synthetase (the enzyme responsible for carnosine synthesis in muscle) to produce more carnosine. Studies document that supplementation of 3.2 to 6.4 g\/day for 4 to 10 weeks increases muscle carnosine concentration by 40 to 80% above baseline values.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eThe intramuscular pH buffering mechanism: how carnosine delays fatigue in high-intensity exercise:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe central physiological mechanism by which carnosine improves performance in high-intensity exercise is intramuscular pH buffering. During high-intensity anaerobic exercise (sprints, maximum repetition sets, high-intensity interval training\/HIIT), anaerobic glycolysis produces pyruvate in excess of what can be oxidized by mitochondria, and the excess is converted to lactate. This conversion is associated with the accumulation of hydrogen ions (H+) in the muscle cytosol, resulting in progressive intracellular acidosis (a drop in intracellular pH from 7.0 to 6.4-6.6) which directly inhibits glycolytic enzymes (especially phosphofructokinase, the central regulatory enzyme of glycolysis), reduces the sensitivity of actin and myosin myofilaments to calcium (affecting muscle contraction capacity), and contributes to the sensation of acute muscle fatigue that forces a reduction in intensity or cessation of exercise. Carnosine has a pKa of 6.83 (very close to intracellular pH during high-intensity exercise), making it an exceptionally effective intracellular buffer in this pH range: it neutralizes accumulated H+, slowing the drop in intracellular pH and prolonging the time the muscle can maintain effort intensity before reaching the acidosis limit.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eConsolidated clinical evidence: meta-analyses document performance improvement in 1 to 4 minute exercises:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe meta-analysis by Hobson et al. (2012), published in Amino Acids with 15 studies and 360 participants, documents that beta-alanine supplementation produces significant and consistent improvements in performance in exercises lasting 1 to 4 minutes of sustained maximum effort, which is precisely the time window in which metabolic fatigue due to intracellular acidosis has the greatest limiting impact. This improvement translates concretely into: a higher number of repetitions performed to muscle failure in high-intensity strength training sets; greater distance covered in maximum effort performance tests lasting 1 to 4 minutes (200 to 1500 meters in swimming, running, and cycling); and greater average power maintained during constant effort cycling tests. The International Society of Sports Nutrition (ISSN) position statement on beta-alanine (Trexler et al., 2015) classifies it as one of the supplements with category A scientific evidence for improving sports performance, alongside creatine and caffeine.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eProgressive accumulation: effects depend on carnosine saturation over weeks, not immediate acute effect:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eUnlike caffeine or creatine (whose effects can be perceived acutely in the first week of use), beta-alanine works by progressive accumulation: the increase in muscle carnosine is gradual and continuous throughout the weeks of supplementation. Studies document that significant increases in muscle carnosine (20 to 30% above baseline) begin to be detectable after 2 to 4 weeks of regular supplementation, with maximum increases (40 to 80%) reached after 8 to 12 weeks. This progressive accumulation dynamic implies that beta-alanine should be taken daily (including on rest days without training, to maintain stable plasma beta-alanine levels and continue to stimulate carnosine synthesis) and that the benefits on sports performance become progressively more pronounced over time, rather than being immediately noticeable.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eParesthesia (tingling): the benign side effect that confirms the active dose:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOne of the most characteristic and frequently mentioned effects of beta-alanine supplementation is acute paresthesia: a tingling, warmth, or \"itching\" sensation on the skin, typically most intense on the face, neck, hands, and ears, which occurs 15 to 20 minutes after ingestion and lasts 60 to 90 minutes. This effect results from the activation of glutamic acid receptors (MrgprD) in cutaneous type C nerve fibers by circulating beta-alanine. Paresthesia is a benign, transient physiological effect with no health consequences, and is not associated with any documented cardiovascular or systemic risk. Its intensity is proportional to the ingested dose and the absorption rate: larger bolus doses (e.g., 3g at once) produce more intense paresthesia than the same fractionated dose. The 1000 mg capsule format, with the recommendation to take 2+1 capsules at different times (2 pre-workout + 1 at another time) instead of all 3 at once, was designed partly to mitigate the intensity of paresthesia by spreading the dose over time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eFree-form beta-alanine: rapid absorption and maximum bioavailability:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe beta-alanine used in this product is in free form (not bound to peptides or encapsulated in sustained-release systems), which ensures rapid intestinal absorption and peak plasma levels within 30 to 45 minutes after ingestion. This rapid absorption profile is responsible for the intensity of paresthesia but also for the rapid availability of beta-alanine to muscle tissues, especially in the pre-workout context where the time window between intake and the start of training is short.\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eUses\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 3 capsules daily, 2 of them before training (15 to 20 minutes before) and the 3rd at another time of day (with breakfast, lunch, or another meal).
