Vitamin D is a fat-soluble vitamin essential for men’s virility and testosterone production. Higher Vitamin D levels are tied to higher total and free testosterone levels in men. Beyond testosterone support, Vitamin D is good for bone strength, immune health, sperm mobility, muscle metabolism and physical performance.

How Vitamin D Helps Testosterone: 

  • Vitamin D Receptors (VDRs) are present in the testes, prostate and sperm. Some believe this reflects Vitamin D’s key roles in reproductive health.
  • Vitamin D-metabolizing enzymes are present in the “T-factory” Leydig Cells, suggesting D may be involved in testosterone synthesis.
  • Vitamin D boosts calcium absorption. Some research shows men experience a bigger jump in T levels when they combine strength training with calcium.
  • Vitamin D assists in keeping Sex Hormone Binding Globulin (SHGB) in check. SHGB hormone binds, neutralizes and diminishes active free testosterone. Vitamin D might boost T by subtracting SHGB.


Vitamin B6 is an essential vitamin involved in over 100 different enzyme reactions in the body. Vitamin B6 serves an important role in the synthesis and breakdown of proteins and amino acids, as well as hemoglobin production and immune function. Vitamin B6 is aids Zinc and Magnesium absorption by the body. Vitamin B6 is also helpful in allowing the muscles to use stored glycogen (storage form of carbohydrates) for fuel during workouts.

How Vitamin B Helps Testosterone: 

  • Vitamin B6 regulates cell receptors that bind hormones.
  • Low levels of Vitamin B6 can negatively affect testosterone levels.


Magnesium is an essential mineral involved in numerous reactions in the body. Magnesium is important for cardiovascular, metabolic, and bone health. Supplementation with Magnesium increases free testosterone and total testosterone. Research has discovered that supplementing with Magnesium can support muscle strength.Nearly 70% of adults are below the recommended daily intake of Mg, with 19% of adults consuming less than half the recommended amount.

How Magnesium Helps Testosterone: 

  • Magnesium inhibits SHBG, the primary offender against active testosterone levels. SHBG is “blocked” by Magnesium’s electrostatic modulation of the Testosterone-SHBG bond.
  • Reduce Oxidative Stress- Magnesium protects against testosterone killing inflammation/oxidative induced by aging and exercise.
  • Magnesium promotes anabolic homeostasis.


Zinc is an essential mineral used by the body to facilitate the conversion of cholesterol to testosterone. Adequate Zinc levels help maintain optimal testosterone production within the normal healthy range.

How Zinc Helps Testosterone: 

  • Zinc manages testosterone synthesis. Zinc is concentrated in the testicles Leydig cells, where it signals for testosterone synthesis and release.
  • Zinc maintains testosterone levels. Zinc has been shown to block the sharp testosterone decline that typically happens during intense workouts.
  • Zinc reduces prolactin levels. Prolactin is a female sex hormone that can drive down healthy testosterone levels. Zinc keeps prolactin in check.

Other Benefits of Zinc for Men: 

  • Zinc improves sperm count, boosts libido and sexual function, and helps with physical performance and recovery. Zinc also seems to boost the male hormone Dihydrotestosterone (DHT).
  • Zinc can be an aphrodisiac and testosterone booster in those who are zinc deficient. In higher doses, Zinc may act to inhibit aromatase.
  • High intensity exercise can deplete zinc levels. Athletes supplemented with zinc do not exhibit the same drop in testosterone seen with placebo in exhausted wrestlers.
  • Low Zinc levels can lead to low androgens (male sex hormones), decreased testicular function, and low physical performance and exercise capacity.
  • Super low Zinc levels are associated with male hypogonadism: a condition where the body doesn’t make enough testosterone, leading to problems such as Erectile Dysfunction (ED), infertility, lost sex drive, loss of muscle strength, brain fog and fatigue, and weak, brittle bones.


Chromium is an essential mineral that may help the body maintain normal blood sugar levels. It is also known for its ability to encourage fat loss and help muscles and other tissues extract nutrients from the bloodstream by supporting the effects of insulin. Chromium can also lower cortisol production and reduce its negative effects in the body. Chromium is thought to have an anti-depressive effect that increases desire/libido.

Chromium, in a form called chromium picolinate, has been studied for its potential role in altering body composition. Preliminary research in animals and humans suggested that chromium picolinate may support fat loss and support a gain in lean muscle tissue. Double-blind research has also reported a reduction in body fat and body weight in people given 400 mcg of chromium (as chromium picolinate) per day for three months.

Chromium Picolinate Can Also: 

  • Help keep your blood sugar level balanced.
  • Increase Energy Levels.
  • Assist in burning fat easier.
  • Assist in building muscle easier.


Boron is a natural mineral required by the human body in order to function properly. Boron is linked to the building of strong bones and muscles and is also linked to mental skills and coordination. Boron has been shown to support free testosterone – the most bioavailable form of testosterone – and supports the muscle building process. Boron also has been scientifically shown to decrease serum estradiol (estrogen) levels within a normal range.

How Boron Helps Testosterone: 

  • Boron potentiates Magnesium and Vitamin D. With the increased bio-availability of these minerals, the body is able to produce testosterone and other important sex hormones at a faster rate.
  • Boron decreases estradiol and sex hormone binding globulin, both which limit testosterone effectiveness.
  • Boron supplementation acutely decreased SHBG and thus increases free testosterone. The elevation in free testosterone has been shown to be 28.3%.


Fenugreek is regarded as a physical performance booster with anabolic muscle-building potential. Published clinical studies show it supports free testosterone levels, helps maintain muscle mass and supports reduction in body fat. Testofen® is a unique extract of Fenugreek standardized to a proprietary matrix of saponin glycosides named Fenuside. These constituents in Testofen® can support healthy sexual desire and vitality, muscle mass, free testosterone levels in men, and help reduce normal symptoms of Andropause in men.

Testofen® Boosts Libido and Maintains Testosterone: 

  • In a randomized, double-blind trial, researchers gave 600 mg Testofen® Fenugreek or placebo to 60 men aged 25-52 for six weeks, and then evaluated them for changes. Testofen® seemed to benefit men’s energy levels, muscle strength, sex drive and feelings of well-being. Blood levels of prolactin and testosterone were unchanged.
  • Researchers concluded that the Testofen® Fenugreek “demonstrated a significant positive effect on physiological aspects of libido” and seemed to help “maintain normal healthy testosterone levels.”

Ginsengs have been used in various traditional medicinal therapies for thousands of years in China and North America. Ginseng is reported to have a wide range of activities, which focus on immunological, central nervous system, acceleration of metabolism, and anti-oxidant properties. Ginseng has been shown to help erectile function, partly due to its nitric oxide boosting mechanism.

How Panax Ginseng Helps Testosterone: 

  • Panax Ginseng reduces stress and provides antioxidant support, two bio-actions associated with healthy testosterone levels.
  • Panax Ginseng decreases Prolactin. Women need Prolactin for milk production during pregnancy. Men experiencing high levels of Prolactin run the risk of low testosterone levels.
