Best Vitamins and Minerals for Testosterone Boosting

Basic vitamins and minerals may not be the most exciting testosterone boosters, but they are important nutrients that every man needs for testosterone.

The problem is, even if they are eating testosterone-building foods, many men fall short on the basic essential nutrients that they need for testosterone and overall health.5

In addition, as men grow older, their ability to absorb and utilize testosterone-supportive vitamins and minerals declines.6

Therefore, the first step in any man's testosterone supplement regimen should be clean, easy-to-absorb vitamin and mineral supplements.

Let's look at the most important vitamins and minerals for testosterone that work.


This testosterone booster mineral is strongly associated with masculine health. It is highly concentrated in the testes, where it plays a role in forming testosterone and regulating its production.7

Notably, low zinc levels are associated with low testosterone symptoms including hypogonadism (shrinking testicle size) and gynecomastia (development of man boobs).8


Magnesium is believed to benefit testosterone levels by blocking sex hormone binding globulins (SHBG) that would otherwise bind and deactivate testosterone in the bloodstream.9

Human clinical research has linked magnesium supplementation with an increase in both free testosterone and total testosterone.10

This particular study included both athletically trained and untrained men. Magnesium was found to benefit both, but the athletic men enjoyed a significantly greater T-boost -- reinforcing the importance of exercise for robust testosterone production.

Men seeking to boost testosterone may need to supplement magnesium: Researchers have suggested that between 56% and 68% of Americans do not get enough magnesium from their diets alone.11 

Vitamin D

Many men can benefit from supplementing with vitamin D. Science has shown that vitamin D receptors and cofactors are present in the testes' Leydig cells that are responsible for producing testosterone.12

Human research has linked vitamin D supplementation to a significant boost in total, free and bioactive testosterone levels in the bloodstream.13


Boron is suggested to help masculine hormones by fighting testosterone disruptive SHBG and estrogen.14

Some research and reviews suggest that supplementing with 10 mg of boron per day can boost testosterone levels in the body after only one week.15

As a bonus, boron helps the body to utilize T-boosting vitamin D and testosterone itself more efficiently, as well as boosting absorption of magnesium.16

Vitamin K

This essential vitamin is found in the testes. It appears to have a link to healthy testosterone levels.

In cases of sub-optimal vitamin K intake in animal studies, testosterone has been shown to decline.17

Animal research also suggests that supplementing with vitamin K helps replenish optimal levels in the testes, and may also help to restore testosterone production.18

Most Effective for T-Boosters: Easy-to-Absorb NutriGenesis® Vitamins & Minerals

To get maximum testosterone support, men must supplement with easy-to-absorb vitamin and mineral forms. This is crucial for mature men in testosterone decline, since some nutrients get harder to absorb with age.

In addition, T-boosting Zinc is difficult to absorb and linked with stomach upset side effects when taken in cheap, low-quality forms.19

NutriGenesis® vitamins and minerals are lab-grown on cultures with whole-food cofactors: Clean, easy to absorb, easy to digest and perfect for testosterone booster supplements.

KSM-66® Ashwagandha

Ashwagandha is a root herb used in traditional health practices for centuries, including the ancient Ayurvedic system of India.

It is known as an adaptogen, which means that it helps the body to fight the effects of stress and otherwise maintain a state of balance.

Ashwagandha is associated with men’s health, especially sex drive and libido, sperm quality and virility – all of which are linked to higher testosterone levels. Some consider it a natural testosterone booster for sex.

Researchers have suggested that Ashwagandha may work by protecting the testes while optimizing the hormonal balance of luteinizing hormone (LH) and Follicle Stimulating Hormone (FSH) (both of which regulate testosterone), as well as optimizing testosterone itself.20

Ashwagandha has been shown in some research to promote multiple measures of masculine health and virility, including:21

  • Supporting cell health within the testes;
  • Improving zinc concentration within the testes;
  • Enhancing semen quality and male virility
Best Ashwagandha form for Testosterone Boosters: KSM-66®

KSM-66® is an organic-certified full-spectrum ashwagandha root extract standardized to supply 5% withanolides (which are the herb's most important active ingredients).

The 5% withanolide concentration makes KSM-66® the most powerful ashwagandha extract available. But that's just the start of its appeal.

KSM-66® has been shown to boost testosterone by 17% (and sperm count by 167%)

In an early human clinical trial, 45 men with less-than-optimal sperm count were given KSM-66® or placebo every day for 90 days. Then, they were tested for several metrics related to masculine health.

At the study's conclusion, researchers reported that men who took the KSM-66® (when compared to placebo) experienced:

  • 17% increase in total testosterone;
  • 34% increase in testosterone supportive luteinizing hormone;
  • 53% increase in semen volume;
  • 167% increase in sperm count
Researchers concluded that Ashwagandha (Withania somnifera) may have therapeutic value for men with low sperm count and fertility concerns.22

KSM-66® is also an athletic performance supercharger.

In addition to supporting testosterone, KSM-66® is prized for its ability to enhance various aspects of athletic performance.

This is crucial in testosterone booster applications because exercise, especially strength training, can significantly boost testosterone levels.

Makers of KSM-66® suggest it may be the best testosterone booster for muscle gain because it helps to:

  • Improve athletic performance and muscle health - Increasing strength and size while accelerating muscle recovery
  • Enhance workout energy without stimulation - Boosting endurance and overall stamina
  • Strengthen mental performance under stress - Improving concentration, clarity and calmness under pressure

KSM-66® may be the best natural testosterone booster on the market.

No other ingredient on the market has KSM-66®'s full-spectrum 2X synergy for masculinity. Only KSM-66®:

  1. Boosts the testosterone that drives peak physical performance in the gym;
  2. Enhances the peak athletic performance that increases testosterone
Look for KSM-66® in the most effective testosterone supplements.

DAA (D-Aspartic Acid)

DAA is an amino acid. Its multiple pro-testosterone activities combine to make it a powerful ingredient to look for in a high-quality testosterone stack.

DAA is naturally present in the endocrine system's glands, but is most highly concentrated in the testes. Here, it appears to function as an orchestrator of testosterone (and other sex hormones).

D-Aspartic Acid may trigger a chain reaction of hormonal events that culminate in testosterone production. It is suggested to work by:

  • Stimulating the hypothalamus to release gonadotropin-releasing hormone (GnRH)23
  • GNRH then stimulates the pituitary gland to ramp up production of the testosterone helper Luteinizing Hormone (LH)24
  • LH then stimulates the testes' Leydig Cells ("T-factories") to start producing testosterone25

While its exact role is somewhat of a mystery, DAA is backed by some impressive research for testosterone benefits in men.

Research has suggested that DAA supplementation may:26

  • Increase testosterone levels by 42% in about 2 weeks;
  • Naturally help to increase Human Growth Hormone (HGH);
  • Increase sperm count by 160%

DAA's crucial role in reproduction just scratches the surface of its potential to increase male testosterone, virility, masculine health and more.

Usage Tip: For superior T-boosting results, stack DAA with an Estrogen Blocker. DAA is a sex hormone supercharger. It is involved in the biosynthesis, stimulation and release of ALL sex hormones. This includes some pro-estrogen effects.

For the greatest possible increase in testosterone, take DAA with an estrogen-blocker. This strategy enables a maximum T-spike, while keeping T-diminishing estrogen in check.

Our next T-Booster is an estrogen blocker that works well with DAA.


Luteolin is an antioxidant compound that may be obtained in the diet in some vegetables and fruits.

It is helpful in testosterone supplements because it blocks an enzyme called aromatase that otherwise would convert testosterone into estrogen.

Luteolin's aromatase-inhibiting activity may help testosterone supplements to work better. Blocking aromatase may help the male body to:

  • Optimize DAA's sex hormone support, allowing testosterone to spike high while blocking its conversion into estrogen;
  • Maintain more youthful androgen levels against age-related imbalance that skews towards more estrogen and less testosterone in a man's prime life years (also called andropause or "male menopause");
  • Protect testosterone in the bloodstream from being converted into estrogen, potentially helping to support and sustain its masculinity-enhancing activity

Luteolin has research for some other health applications as well. When it comes to its impact on testosterone, luteolin research is still early.

However, some researchers have proposed that luteolin appears to be effective at blocking aromatase and regulating estrogen levels in the body.27

Mucuna Pruriens (Velvet Bean)

This seed has a long history of use traditional herbalism, especially for male potency and performance in the bedroom.

Mucuna contains an active ingredient called L-DOPA (levodopa). L-DOPA is suggested to have a few different bioactivities that help testosterone and masculine health.

Researchers suggest L-DOPA from Mucuna pruriens triggers a chain reaction in the Hypothalmus-Pituitary-Gonadal Axis.

It starts by stimulating the brain to release gonadotropin-releasing hormone (GnRH), which then stimulates the pituitary gland to produce follicle stimulating hormone (FSH) and luteinizing hormone (LH).28

  • GnRH, FSH and LH are all involved in the hormonal processes that culminate in testosterone production in the testes.

Mucuna is backed by some research for testosterone and masculine vitality.

One human clinical trial tracked 75 men with low sperm count, low testosterone and less-than-optimal levels of luteinizing hormone. The men supplemented with mucuna pruriens seed powder every day for 3 months.

At the study's end, researchers reported mucuna supplementation raised and normalized testosterone and LH levels, as well as boosting sperm count and sperm motility.

Researchers concluded that Mucuna may have the ability to enhance secretion of semen, influence testosterone levels, improve performance and increase male sex drive.29
