The daily dose of 3 capsules provides: 750 mg of Tribulus extract (675 mg of saponins) + 225 mg of elemental magnesium + 15 mg of elemental zinc + ~2 mg of vitamin B6. 100 capsules (~33 days with 3 capsules\/day).

The combination of the two mechanisms ensures that Tribulus stimulates the hormonal signal (LH) and ZMA ensures that the biochemical machinery to respond to that signal (testosterone synthesis enzymes) is functioning with all available cofactors.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTribulus terrestris 250 mg (90% saponins) per capsule: the LH and testosterone stimulant:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAs detailed in the description of Life Pro's \u003cstrong\u003eTribulus Pro\u003c\/strong\u003e, Tribulus terrestris extract standardized to 90% saponins provides protodioscin and other steroidal saponins that stimulate pituitary LH secretion and testicular testosterone production, in addition to documented effects on libido, vitality, and sexual health in clinical trials. The dose of 250 mg per capsule (750 mg\/day with 3 capsules) is a modest but functional dose, consistent with studies documenting effects with 500 to 750 mg\/day of Tribulus extract with high saponin content.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMagnesium bisglycinate (375 mg\/capsule = 75 mg elemental magnesium): the most deficient mineral in athletes and essential for testosterone synthesis:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMagnesium (Mg²⁺) is the fourth most abundant cation in the human body and a cofactor for over 300 enzymatic reactions, including multiple steps of testosterone synthesis (testosterone synthesis from cholesterol involves several ATP-dependent enzymatic steps, and ATP primarily exists as a Mg-ATP complex). In addition to its direct role in testosterone synthesis, magnesium regulates testosterone bioavailability: magnesium competes with SHBG (sex hormone-binding globulin, the protein that transports and inactivates testosterone in plasma) for the testosterone binding site, increasing the fraction of biologically active free testosterone. The study by Cinar et al. (2011), published in Biological Trace Element Research with 30 athletes and 30 sedentary individuals, documented that magnesium supplementation (10 mg\/kg\/day for 4 weeks) significantly increased total and free testosterone levels at rest and after exercise compared to the control group. Magnesium bisglycinate (the glycine-chelated form used in this formula) is the form of magnesium with the highest bioavailability and best gastrointestinal tolerance among all available forms of magnesium, with 43% to 90% greater absorption than magnesium oxide or magnesium sulfate, and without the laxative effect common in inorganic forms.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eZinc citrate (15.15 mg\/capsule = 5 mg elemental zinc): the most critical mineral for testosterone synthesis and spermatogenesis:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eZinc plays an absolutely central role in testosterone biosynthesis. The enzyme \u003cstrong\u003e17β-hydroxysteroid dehydrogenase\u003c\/strong\u003e (17β-HSD, which catalyzes the final step of converting androstenedione to testosterone in the testes) is a metalloenzyme that requires zinc as a structural and catalytic cofactor. Zinc deficiency therefore results in an inability to complete testicular testosterone biosynthesis, regardless of the level of LH stimulation. In addition to this role in biosynthesis, zinc inhibits \u003cstrong\u003earomatase\u003c\/strong\u003e (the enzyme that converts testosterone to estradiol in peripheral tissues, especially adipose tissue), reducing the peripheral conversion of testosterone to estrogens and increasing the testosterone:estrogen ratio. EFSA has approved the health claim that zinc contributes to the maintenance of normal testosterone levels in the blood. Zinc is also essential for spermatogenesis: the testes have one of the highest concentrations of zinc in the body, and zinc deficiency causes oligospermia (low sperm count), asthenospermia (low motility), and teratospermia (abnormal morphology). The zinc citrate used in this formula is one of the organic forms of zinc with better bioavailability, superior to zinc oxide (the cheapest and least absorbed form often used in inferior quality supplements).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVitamin B6 (0.66 mg\/capsule): the cofactor for hormonal metabolism and neurotransmitter synthesis:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eVitamin B6 (pyridoxine) is a water-soluble vitamin that, in its active form of pyridoxal-5-phosphate (PLP), is a cofactor for over 100 enzymatic reactions in the human body, including multiple reactions of amino acid metabolism (transaminations) and neurotransmitter biosynthesis (serotonin via tryptophan hydroxylase, dopamine via DOPA decarboxylase, GABA via glutamate decarboxylase). In the hormonal context, B6 has a documented role in regulating steroid receptors: it regulates the activity of glucocorticoid receptors (decreasing sensitivity to cortisol) and can modulate androgen receptor activity, with a net effect of supporting the androgenic environment. The ZMA combination (Zinc, Magnesium, B6) was originally patented by nutritionist Victor Conte (founder of BALCO) and strength coach Lorrie Brilla, with the clinical trial by Brilla \u0026 Conte (2000) documenting that ZMA supplementation for 7 weeks in American football players increased IGF-1 levels by 25% and free testosterone by 33% compared to placebo, with greater gains in muscle strength. Although later studies have had more mixed results, the Zn+Mg+B6 combination has a solid evidence base, especially in athletes with subclinical deficiencies of these nutrients.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eThe particular importance of ZMA for athletes with high training loads:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eZinc and magnesium are the two minerals most lost through sweating during intense exercise. Published estimates document magnesium losses of 10 to 60 mg\/hour of intense exercise (depending on intensity and ambient temperature) and zinc losses of 0.5 to 1.5 mg\/hour. Athletes who train 1 to 2 hours\/day, 5 to 6 days\/week can lose 50 to 360 mg of magnesium\/week and 2.5 to 9 mg of zinc\/week through sweating, which represents a significant fraction of the recommended daily allowances (RDAs) for magnesium (300 to 400 mg\/day) and zinc (8 to 11 mg\/day). ZMA supplementation replenishes these losses and ensures optimal availability of both minerals for the biochemical processes of testosterone synthesis, muscle contraction, and recovery.\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\/day, distributed among the 3 main meals (1 capsule at breakfast + 1 at lunch + 1 at dinner), preferably with food to maximize the absorption of magnesium and zinc. Alternatively, all 3 capsules can be taken together 30 to 60 minutes before bedtime, to take advantage of the nighttime peak of LH and testosterone secretion during sleep (preferred strategy by many users).
