Ashwagandha (Withania somnifera) is an adaptogenic herb used for over 3,000 years in Ayurvedic medicine. KSM-66® is the most clinically studied ashwagandha extract available — a full-spectrum root extract developed by Ixoreal Biomed, standardized to ≥5% withanolides. Unlike root-and-leaf extracts, KSM-66® uses only root material, maintaining the traditional Ayurvedic extraction approach while delivering a highly concentrated, bioavailable form.
The testosterone-supporting mechanism of ashwagandha operates primarily through the HPA axis (hypothalamic-pituitary-adrenal axis). Chronic stress elevates cortisol, which directly suppresses luteinizing hormone (LH) production. LH is the signal that triggers Leydig cells in the testes to produce testosterone. By reducing cortisol levels, ashwagandha restores LH signaling and supports the testosterone-production pathway. Additionally, ashwagandha has shown direct effects on testosterone in men with reproductive concerns in randomized controlled trials.
A landmark 2012 double-blind, randomized, placebo-controlled trial by Chandrasekhar et al. (Journal of Indian System of Medicine) found that 600mg/day of KSM-66 ashwagandha root extract reduced cortisol by 27.9% and significantly improved stress scores compared to placebo (n=64 adults). A 2015 trial published in the Journal of the International Society of Sports Nutrition found significant improvements in muscle strength, recovery, and testosterone levels in resistance-trained men taking 300mg twice daily (600mg/day) over 8 weeks. The 600mg/day dose used in SodaPeak® matches these study protocols directly.

Tongkat Ali (Eurycoma longifolia Jack) is a tree native to Southeast Asia, particularly Malaysia and Indonesia. Known locally as "Malaysian ginseng" or "Long Jack," it has been used in traditional medicine for male vitality enhancement for centuries. Modern research has identified specific active compounds — quassinoids, canthin-6-one alkaloids, and beta-carboline alkaloids — responsible for its hormonal effects.
Tongkat Ali's primary mechanism for increasing bioavailable testosterone involves the reduction of sex hormone-binding globulin (SHBG). SHBG binds to testosterone in the bloodstream, rendering it biologically inactive. By reducing SHBG activity, Tongkat Ali increases the ratio of free (active) testosterone. Additionally, active compounds in Tongkat Ali stimulate steroidogenesis in Leydig cells and may increase LH secretion, further supporting testosterone production at the source.
A 2013 randomized, double-blind, placebo-controlled study by Talbott et al. (Journal of the International Society of Sports Nutrition) found that 200mg/day of Tongkat Ali extract significantly reduced cortisol by 16%, increased testosterone by 37%, and improved Mood State scores compared to placebo in moderately stressed adults (n=63, 4-week trial). This dose — 200mg — is exactly what SodaPeak® contains, matching the studied protocol precisely.

Fenugreek (Trigonella foenum-graecum) is a legume seed used in cooking and traditional medicine across South Asia and the Middle East. In men's health supplementation, fenugreek standardized extract is studied specifically for its steroidal saponins — particularly protodioscin — which influence testosterone metabolism pathways.
Fenugreek operates through two key testosterone-supporting mechanisms: (1) Aromatase inhibition — aromatase is the enzyme that converts testosterone to estradiol (estrogen). By inhibiting aromatase activity, fenugreek reduces this conversion and maintains higher testosterone levels; (2) 5-alpha reductase inhibition — this enzyme converts testosterone to dihydrotestosterone (DHT). By partially inhibiting this pathway, fenugreek helps preserve free testosterone. The net result of both mechanisms is increased bioavailable testosterone, particularly free testosterone fractions.
A 2011 randomized, double-blind, placebo-controlled trial by Steels et al. (Phytotherapy Research) evaluated 600mg/day of fenugreek extract in healthy men aged 25–52 over 6 weeks. The fenugreek group showed significantly higher free testosterone compared to placebo, with improvements in sexual function, libido scores, and maintenance of normal testosterone levels. The 500mg dose in SodaPeak® is well within the therapeutic range studied in clinical literature.

Panax ginseng (Korean ginseng or Asian ginseng) is one of the most extensively studied herbs in the world, with over 2,000 years of documented use in Traditional Chinese Medicine (TCM). Its active compounds — ginsenosides (also called panaxosides) — are steroidal saponins with diverse biological activities affecting the central nervous system, immune function, cardiovascular system, and endocrine axis.
Ginsenosides influence male vitality through several pathways: (1) Nitric oxide stimulation — ginsenosides activate endothelial nitric oxide synthase (eNOS), increasing NO production in vascular tissue, which supports blood flow; (2) Leydig cell stimulation — specific ginsenosides have been shown to stimulate testosterone synthesis in Leydig cells through LH-receptor activation; (3) Adaptogenic stress modulation — like ashwagandha, Panax ginseng modulates the HPA axis response to stress, supporting cortisol balance.
Multiple systematic reviews and meta-analyses support Panax ginseng's role in male sexual function. A comprehensive 2008 systematic review in the British Journal of Clinical Pharmacology analyzed 7 randomized controlled trials and concluded that Panax ginseng "appears to improve erectile function." A 2012 review in the Asian Journal of Andrology found consistent improvements in IIEF (International Index of Erectile Function) scores with ginseng supplementation versus placebo across multiple studies. The standardized 200mg dose in SodaPeak® is within the effective dose range cited in clinical literature.

Zinc is an essential trace mineral that participates in over 300 enzymatic reactions in the human body. For men's hormonal health, zinc's role is uniquely central: it is a required cofactor for the enzymatic conversion of cholesterol to pregnenolone (the first step in steroidogenesis) and for several enzymes in the testosterone biosynthesis cascade within Leydig cells. Without adequate zinc, testosterone production cannot proceed at full capacity regardless of other factors.
Zinc deficiency is more common than widely recognized. Athletes and physically active men lose zinc through sweat, creating elevated depletion risk. Men on plant-based or low-red-meat diets also often have marginal zinc status. A landmark study by Prasad et al. (1996) found that even marginal zinc deficiency in young men produced significant reductions in serum testosterone — and that zinc supplementation in deficient men produced a significant testosterone recovery. The implication: for any man who is marginally zinc-deficient, supplemental zinc can produce meaningful testosterone increases.
SodaPeak® uses zinc citrate — one of the most bioavailable forms of supplemental zinc. Studies comparing zinc absorption across different forms consistently rank zinc citrate and zinc picolinate as superior to zinc oxide and zinc sulfate. A comparative study found zinc citrate provided comparable bioavailability to zinc gluconate, both significantly exceeding zinc oxide. For a gummy supplement formula, zinc citrate's superior absorbability ensures the 15mg dose delivers meaningful blood-level changes.

Vitamin D3 (cholecalciferol) is technically a prohormone — it is metabolized in the kidneys to calcitriol, a steroid hormone with receptors found throughout the body including in Leydig cells (testosterone-producing cells), Sertoli cells, and cells in the HPG axis (hypothalamic-pituitary-gonadal axis). The fact that testosterone-producing cells have vitamin D receptors strongly suggests a functional relationship between vitamin D status and testosterone production.
Epidemiological data consistently shows a positive correlation between vitamin D status and testosterone levels. Men with higher serum 25(OH)D concentrations consistently have significantly higher testosterone levels in cross-sectional studies. A landmark 12-month randomized controlled trial by Pilz et al. (2011, Hormone and Metabolic Research) found that men receiving 3,332 IU vitamin D daily had total testosterone increase by 25.2% vs. 2.2% in the placebo group — a dramatic, statistically significant difference over 12 months. The 2,000 IU dose in SodaPeak® provides a safe, daily maintenance level of vitamin D3 that addresses the widespread deficiency in American adult men.
According to the NIH and multiple population studies, more than 40% of American adults are vitamin D deficient (serum 25(OH)D <20 ng/mL), and a further significant proportion are insufficient (20–29 ng/mL). For these men — nearly half the adult male population — vitamin D3 supplementation is not optional supplementation but a genuine nutritional correction with direct downstream effects on testosterone.
