Best Supplements To Naturally Boost Testosterone

Table Of Contents

Supplements are one of the fastest ways to naturally and safely increase your Testosterone levels.

The most effective supplements boost Testosterone by targeting the root causes of low Testosterone:

  • Excess Inflammation
  • Vitamin Deficiencies
  • High Cortisol Levels (High Stress Levels)
  • High Estrogen Levels
  • High Blood Sugar & Insulin Resistance
  • Low Free Testosterone

The most effective supplements to maximize Testosterone are:

Boron (Boosts Free Testosterone By 28%)

Boron Boosts Testosterone By 28%

Boron is one of nature’s best Testosterone boosters.

Boron increases free testosterone levels by up to 25% in just 1 week when consumed at 6mg a day (NCBI, 2015)

The 2015 study “Nothing Boring About Boron” found:

  • Boosts Free Testosterone by 25% at 6mg per day in 7 days
  • Boosts Free Testosterone by 28% at 10mg per day in 7 days
  • Boron reduces Estradiol (a.k.a Estrogen) by almost 50%
  • Boron increased Vitamin D3 levels by 19.4%
  • Boron increases the half life of Vitamin D3 & fixes Vitamin D3 deficiency – Vitamin D3 plays a crucial role in the production of Testosterone
  • Boron reduces Inflammation by more than 50%

Recommended Dosage:

The recommend dosage of Boron to maximise Testosterone levels is 6mg to 10mg per day.

Best Boron Supplement:

The Boron supplement I recommend is Testogen, which contains 8mg of Boron per serving

ZMA (Boosts Testosterone By 33.4%)

ZMA Raises Testosterone By 33%

ZMA is a patented combination of:

  • 30mg of Zinc,
  • 450mg of Magnesium and
  • 10.5mg of Vitamin B6

In 2000, Washington State University conducted an 8 week study on the impact of ZMA supplementation on American Football Players. The athletes supplemented on ZMA each night before going to sleep. The study discovered:

  • ZMA increased Free Testosterone by 33.4% (ASEP, 2000).
  • ZMA increased muscle size & diameter by 11.6% (compared to 4.6% increase in placebo group).
  • ZMA increased quadricep & leg press strength by 12.8% to 15.2% (5% more than placebo)
  • ZMA increased IGF-1 BY 3.5% (compared TO 21.4% decrease decrease in placebo group). Insulin Like Growth Factor 1 regulates muscle growth & hypertrophy (SPRINGER, 2011).

How ZMA Increases Testosterone Production

Zinc is an essential mineral & anti-oxidant that plays a key role in more than 300 chemical processes within the body.

Zinc is essential for the production of Testosterone – helping the body to convert cholesterol to Testosterone (NCBI, 2019). Zinc also reduces free radical damage & lowers inflammation (2 causes of Low Testosterone).

In a 2019 study, men supplementing on 30mg of Zinc per day for 20 weeks had 296% higher Testosterone levels than men who were eating a Zinc restricted diet & had Zinc deficiency (NCBI, 2019).

Magnesium supplementation has been sown to significantly increase Testosterone (PUBMED, 2020)

Magnesium is used to produce the most powerful antioxidant in the body, Glutathione. Glutathione significantly reduces inflammation and free radical damage, significantly increasing Testosterone production.

Magnesium deficiency is linked to Low Testosterone. Magnesium deficiency leads lowers Glutathione levels. Low Glutathione is linked to:

  • Excess inflammation
  • Free radical damage in the body(Source, Source)

High levels of Inflammation and free radical damage are linked to low Testosterone levels.

Magnesium supplementation is essential to maximise Testosterone levels via increasing Glutathione and reducing inflammation.  

Best ZMA Supplement

I highly recommend On Nutrition’s ZMA formula which you can from Amazon.com (if you are in the USA) or Amazon.co.uk (if you are in the United Kingdom).

Fenugreek (Boosts Free Testosterone By 46%)

Fenugreek Incrreases Free Testosterone By 46%

In a 12 week study, supplementing on 500mg of Fenugreek per day (without exercise) increased Free Testosterone by 46% in men aged 35 to 65. (PUBMED, 2017)

An 8 week study in young men working out 4 days a week found supplementing on 300mg of Fenugreek daily:

  • Increased Free Testosterone by 98% (compared to 48% increase in placebo) (PUBMED, 2016).
  • Increased 1 rep max strength on leg press & bench press by 8kg more than placebo. (PUBMED, 2016).
  • Athletes supplementing Fenugreek lost 2% more body fat than placebo. (PUBMED, 2016).
  • Fenugreek increased the number of repetitions to failure on all exercises by 2 reps (compared to 0% increase in placebo). Athletes supplementing Fenugreek had higher exercise endurance and were able to complete 2 more reps than placebo group on all exercises. (PUBMED, 2016)

Fenugreek increases Testosterone levels by fixing the root causes of low Testosterone:

  • Reducing inflammation;
  • Decreases high blood sugar & improving insulin sensitivity.
  • Preventing the conversion of Testosterone to Estrogen & DHT

Fenugreek is rich in saturated, monounsaturated & polyunsaturated fats that significantly reduce inflammation levels. 

According to the 2017 Chilean Journal of Agricultural Research, Fenugreek seeds & extract contain the following essential fatty acids:

  • Polyunsaturated fats: 37.9% linoleic acid & 28.2% alpha-linolenic acid
  • Monounsaturated fats: 13.3% oleic acid
  • Saturated fats: 3.8% stearic acid & 13.1% palmitic acid

All these essential fatty acids significantly decrease inflammation to increase Testosterone. 

Furthermore, the researchers of the 2016 study concluded:

  • Fenugreek increases Testosterone by preventing the conversion of Testosterone to Estrogen & DHT  (PUBMED, 2016);
  • Fenugreek inhibits the Aromatase enzyme from converting Testosterone to Estrogen; (PUBMED, 2016)
  • Fenugreek reduces 5 Alpha Reductase activity & reduces conversion of Testosterone to DHT. (PUBMED, 2016)

Fenugreek contains: Linoleic acid, Alpha Linolenic Acid & Oleic Acid fatty acids (PUBMED, 2017) – which are the most potent natural inhibitors of 5 Alpha reductase & can reduce DHT levels to aid hair loss prevention. A 2006 six month study in men and women experiencing hair loss found over 82.9% reported a positive and noticeable difference in hair volume and thickness from Fenugreek extract.

Recommended Dosage:

To maximize Testosterone, supplement on 300 to 500mg of Fenugreek extract daily.

Best Fenugreek Supplement

I personally use & recommend Now Fenugreek on Amazon which contains 500mg of Fenugreek extract per serving.

Vitamin D3 (Boosts Testosterone By 25%)

Get 1 Hour Of Sunshine Each Day To Boost Testosterone By 68 Ra God Of The Sun

Vitamin D3 plays a crucial role in the production of Testosterone. 

  • Vitamin D3 Supplementation increases Testosterone Levels By 25% at 3,300 IUs per day (PUBMED, 2010)
  • Vitamin D3 Deficiency Is Correlated With Low Testosterone Levels & Impaired Immune Function (PUBMED, 2010)

Vitamin D3 Deficiency Causes Low Testosterone

The body produces Vitamin D3 when exposed to sunlight.

However, the majority of the population has very little sunlight exposure, especially during winter time.

As a result, a large percentage of men have Low Testosterone due to Vitamin D3 deficiency. 

Vitamin D3 Boost Testosterone by 25% at 3300 IU’s per day 

In one year long study, supplementing on 3,300IUs of Vitamin D3 doubled Vitamin D levels and boosted Testosterone levels by 25%, from 10.7 nmol/l to 13.4 nmol/l on the blood test. (PUBMED, 2010)

This makes Vitamin D3 a powerful Testosterone booster. Higher levels of Testosterone allow your body to build more muscle and burn more fat (PUBMED, 1989).

Additionally, supplementing on 420IU’s of Vitamin D3 increased muscle mass by 0.5KG in 1 year in men who didn’t even work out. (PUBMED, 2019)

Recommended Dosage:

To maximise Testosterone: 2,000 to 4,000 IU’s Per Day of Vitamin D3.

The safe limit of Vitamin D3 is 10,000 IUs per day.

Make sure to supplement Vitamin K2 alongside Vitamin D3 to prevent side effects of Excess Vitamin D3 levels (excess calcium levels and calcium depositing on soft tissue like muscle).

For Every 2000IUs of Vitamin D3, Take 30 to 50IUs of Vitamin K2.

  • 2000 IUs Vitamin D3, take 30 to 50 IU of Vitamin K2
  • 4000 IUs of Vitamin D3, take 60 to 100IU of Vitamin K2

Best Vitamin D3 Supplement:

Testogen is the Vitamin D3 supplement I personally use and recommend – which contains 2,000 IUs of Vitamin D3 carefully balanced with 30IUs of Vitamin K2 per serving.

Ashwagandha (Boosts Testosterone By 22%)

Ashwagandha Boosts Testosterone

  • Increases Testosterone by 17% to 22% At 500mg per day (Source)
  • Reduces Cortisol (Stress Hormone) By 16%
  • Increases Strength, Muscle Mass, Endurance & Workout Recovery

Ashwagandha has been used for thousands of years in Asian and Chinese as an adaptogenic herb to reduce anxiety and stress.

Cortisol is the primary stress hormone produced by the body. High levels of Cortisol suppress Testosterone production – significantly reduce Testosterone levels.

Cortisol is also a catabolic hormone. Excess cortisol levels break down muscle protein to convert it into glucose for energy during intense workouts if blood sugar is low or a workout is too long.

Excess Cortisol reduces muscle strength, impairs muscle growth and inhibits workout recovery. Additionally, high cortisol levels decrease Metabolism and make fat loss harder.

As an adaptogenic herb – Ashwagandha reduces excess cortisol levels  to optimal range – lowering stress & increasing Testosterone by 17 to 22% when supplemented at 500mg per day.

By reducing cortisol, Ashwagandha keeps your body in an anabolic state (building new cells and muscle growth) – preventing your body from going catabolic during long and intense workouts.

Ashwagandha Increases Muscle Mass & Improves Exercise Performance

A 2009 study found 8 weeks of Ashwagandha supplementation increased Testosterone, significantly improved exercise strength, increased muscle mass, boosted fat loss & recovery in men working out.

Study Result Statistics

  • Testosterone gains: Men supplementing on Ashwagandha increased their Testosterone by almost 100ng/DL while placebo increased their Testosterone by only 18ng/DL in 8 weeks.
  • Strength gains: Men supplementing on Ashwagandha increased their bench press by 20KG more than placebo group (men not supplementing on Aswagandha) and increased leg extension by 5KG more.
  • Muscle gains: Men supplementing on Ashwagandha gained 1 inch more on their arm and chest size in 8 weeks than placebo group.
  • Fat Loss: Ashwagandha group lost 2% more body fat than placebo group

Recommended Dosage:

500mg of Ashwagandha per day

Best Time To Take Ashwagandha:

Cortisol lowering supplements like Ashwagandha are best taken:

  • 30 minutes to 1 hour before a workout
  • Before going to bed

By lowering your Cortisol before a workout with Ashwagandha, you increase your strength levels and increase anabolism (muscle growth and repair) in the body. You also prevent your body going catabolic during your workout.

The body produces almost all Testosterone during sleep. If we have high cortisol levels during sleep, our body will not produce high levels of Testosterone. If cortisol is low during sleep, higher levels of Testosterone will be produced.

Best Ashwagandha Supplement:

The Ashwagandha supplement I personally use and recommend is NutraVita Ashwagandha from Amazon.co.uk  which contains 500mg of KSM 66 extract Ashwagandha (the most potent form of Ashwagandha).

ashwagandha ksm 66

It is combined with Bioperine® (a patented form of Black Pepper Extract) – which increases nutrient absorption by at least 30% (BIOPERINE, 2021) and increases the supplement’s potency & positive effects. 

Due to being a UK brand, it only ships in the UK. If you are in the USA, Nutricost Ashwagandha is fantastic alternative which contains 600mg of KSM66 Ashwagandha combined with Bioperine. 

Tongkat Ali (Boosts Testosterone By 46%)

Tongkat Ali Boosts Testosterone By 46 Green

Tongkat Ali  is an adaptogenic herb that works similarly to Ashwagandha – increasing Testosterone by reducing high Cortisol – reducing anxiety and stress.

Tongkat Ali is also known as Eurycoma Longifolia, Malaysian Gingseng or simply Long Jack.

Benefits Of Tongkat Ali

Tongkat Ali Boosts Testosterone By 34% To 46%

In a 4 year study conducted in 320 hypogonadal men (men with low Testosterone under 170ng/dL), supplementing on 200mg/day of Tongkat Ali:

  • Tongkat Ali increased Free Testosterone by 46% (PubMed, 2012)
  • After the study, 90% of men had normal Testosterone levels. (PubMed, 2012)

In a 4 week 2013 study conducted in 32 men and 31 women using 200mg/day Tongkat Ali water soluble extract :

  • Tongkat Ali Increased Free Testosterone Levels By 37% (NCBI, 2013)
  • Tongkat Ali Reduced The Stress Hormone Cortisol By 16% (NCBI, 2013)
  • Tongkat Reduced Anger By 12% (NCBI, 2013)

In a 2021 study in young athletes (aged between 21 to 27) using 600mg/day of Tongkat Ali extract for 2 weeks:

  • Tongkat Ali increased Total Testosterone by 15% (NCBI, 2021)
  • Increased Free Testosterone  by 34% (NCBI, 2021)

While having no effects on FSH, LH and SHGB.(NCBI, 2021)

Tongkat Ali increases Total Testosterone and Free Testosterone by a larger amount in men who suffer from low T than in healthy men with normal Testosterone. 

Tongkat Ali Improves Athletic Performance & Increases Lean Muscle Mass

In a 5 week study conducted in 14 men working out 4 to 5 days per week using 100mg of Tongkat Ali water soluble extract:

  • Gained 2.13kg of lean muscle mass from 52.26KG to 54.39KG (while placebo gained none) (BMJ, 2001)
  • Increased arm circmference (arm size) by 1.8cm (with no significant increase in placebo) (BMJ, 2001)
  • Decreased body fat by 2.86% (while placebo lost 1.5% body fat) (BMJ, 2001)
  • Increased 1 rep max by 5kg (while placebo increased by only 2kg) (BMJ, 2001)

The results suggest that water soluble extract of Eurycoma Longifolia increased fat free mass, reduced body fat, and increased muscle strength and size, and thus may have an ergogenic effect. (BMJ, 2001)

Tongkat Ali Improves Libido By 10.8%

Tongkat Ali increased libido by 10.8% at 300mg per day in 6 week study (NCBI, 2012)

Tongkat Ali Increases Sperm Count By 65.5%

In a 9 month 2010 study, 200mg of Tongkat Ali:

  • Tongkat Ali increased sperm count by 65.5% (NCBI, 2010)
  • Tongat Ali increases ejaculation volume by 19.3% (NCBI, 2010)

Recommended Dosage:

200mg to 600mg per day of Tongkat Ali was the effective dosage used to maximise Testosterone in the scientific studies.

Best Tongkat Ali Supplement:

I highly recommend  Nutricost’s Tongkat Ali from Amazon, which contains 500mg of Tongkat Ali 200:1 extract per serving with no artificial colours or preservatives.

NutriCost Tongkat Ali

Fadogia Agrestis (Boosts Testosterone By 200% In 5 Days)

Does Fadogia Agregatis Boost Testosterone

Fadogia Agrestis is a small bush shrub found in many parts of Africa, including Nigeria & Ghana.

Fadogia contains phytochemicals called saponins, alkaloids & flavonoids which have anti inflammatory properties responsible (NCBI, 2005). The saponins inside Fadogia increase Luteinizing Hormone levels, stimulating the testes to increase Testosterone production. (NCBI, 2005).

A 2005 study in male Albino rats found Fadogia Agrestis increased testosterone in a dose dependant manner:

After only 5 days of supplementation (NCBI, 2005).

Fadogia increased libido by 370%.

Fadogia increased ejaculation latency by 250%  –prolonging the time it takes to ejaculate helping subjects last 2.5 times longer during sex. (NCBI, 2005).

Fadogia increased testicular weight by 11 to 15% after 28 days (NCBI, 2005). via increasing lipid peroxidation (oxidative stress & free radical damage to cells in the testes). However, no clinical toxicity was observed in the liver and kidney (NCBI, 2009).

No human studies have been conducted.

Recommended dosage

500mg to 1000mg per day. Fadogia should be cycled & used for short periods of time.

Pycnogenol® (Boosts Testosterone By 19%)

Pycogenol Boosts Testosterone By 19%

Pycogenol® is a patented French tree bark extract.

80mg of Pycogenol® with 3 grams of L-Arginine increased Testosterone by 19% (Pubmed, 2010).

Benefits Of Pycnogenol®

  • Pycogenol® significantly reduces inflammation and insulin resistance (root causes of low testosterone) (Examine, 2021)
  • Pycogenol® increases nitric oxide production and is a vasodilator – increasing blood flow to muscles & genitals – significantly improving muscle pumps & improving erection quality.
  • Pycogenol® is a natural alternative to Viagra to fix erectile dysfunction (examine, 2021)

Pycogenol® improves athletic performance.

  • Athletes using Pycogenol® were able to run 21% further in 30 days on treadmill compared to placebo (Arbovitae, 2014).
  • Athletes performing the army fitness test using Pycogenol®: ran 2 miles faster by 11% and performed 21% more sit ups & 13% more push ups (Pubmed, 2013).
  • Athletes competing in triathlon improved their running time by 5 minutes (10% faster) (Pubmed, 2013)
  • Pycogenol® improves muscle recovery & reduces muscle cramping by 25% (Pubmed, 2005) 

Pycogenol® also reduces high blood pressure at dosages over 150mg. (Pubmed, 2002)

Pycogenol’s main mechanism of action is via vasodilation – increasing blood flow (allowing more nutrients to reach your cells) and reducing inflammation (root cause of Low Testosterone)

Optimal Dosage Of Pycnogenol® 

Optimal dosage for Pycnogenol® is between 60 to 200mg daily (Examine, 2021).

For optimal results, supplement L Arginine at 500mg to 1 gram per day alongside Pycnogenol®.

L Arginine gets converted to L Citrulline, which increases nitric oxide production, improves blood flow, athletic performance, and erection quality synergetically alongside Pycnogenol®.

Best Pycnogenol® Supplement

I personally use and recommend Now Pycnogenol from Amazon, which contains 100mg of Pycnogenol extract per capsule.

It contains no artificial colours, flavourings or preservatives. 

Pycnogenol Now Nutrition Boosts Testosterone

D Aspartic Acid (Boosts Testosterone By 30% To 60%)

Bodybuilder Taking Boron Supplements To Boost Testosterone

However, studies conducted in healthy young men found no significant increase in Testosterone.

Recommended Dosage:

1.5g to 3grams per day of DAA to maximise Testosterone.

Best DAA Supplement:

The best DAA supplement is Testogen, which contains 2.4 grams of D Aspartic Acid.

Probiotics (Boost Testosterone By 22%)

Probiotics Supplement Boosts Testosterone

Probiotics are good bacteria. Supplementing on probiotics will indirectly increase Testosterone by fixing 3 major causes of Low Testosterone:

  • Fix Gut Dysbiosis (imbalance of good and bad bacteria in your gut) and improve your gut health.
  • Significantly lower  inflammation,
  • Improve leaky gut and repair gut damage (Root cause of high inflammation)
  • Fixes hormonal imbalance (boosting Testosterone levels)
  • Reduces stress & improves the body’s ability to deal with stress by 50%(reduce high cortisol levels)

The Best Probiotic Supplements

You want a probiotic supplement that contains the following live cultures:

  • Lactobacillus Acidophilus
  • Bifidobacterium Lactis
  • Bifidobacterium Bifidum
  • Lactobacillus Paracasei

These 4 bacteria cultures significantly improve gut health and lower inflammation.

Lactobacillus Paracasei lowers inflammation, repairs gut damage, and improves testicular function and testosterone production in men
(Pearce et al, 2017). It also improves heart health and increases HDL (good) cholesterol. Supplementing on L. Paracasei is an effective way to improve gut health and fix low Testosterone. (Pearce et al, 2017). The scientists behind the study said supplementing on L. Paracasei has “superior therapeutic potential” in treating low T. 

Lactobacillus Reuteri is another strain of probiotics that has been shown to increase testosterone levels, sperm count, and testicle size (PubMed, 2014). However, all studies on L. Reuteri were conducted on mice. 

I recommend supplementing with a probiotic supplement that contains at least 10 billion to 50 billion live probiotic cultures. This ensures the bacteria will be able to colonize and inhabit your gut. 

The probiotic supplement I personally use and recommend is: MaxMedix Probitoic from Amazon.co.uk, which contains 60 billion live cultures and 20 different strains of probiotic like L Paracasei that significantly lower inflammation.

max medix probiotic

This is by far one of the most comprehensive and potent probiotic on the market in UK and Europe. 

If you’re in the USA, Physician’s Choice 60 Billion Probiotic With Prebiotic Fibre Blend  is a great choice,  which contains 10 different probiotic strains like L Paracasei.

probiotic to boost testosterone

Testogen – All In One Testosterone Booster

Pycogenol Boosts Testosterone By 19%

I personally use & recommend Testogen.

It contains 11 of the most effective Testosterone boosting supplements at the effective dosage:

Testogen Ingredient Breakdown

It includes the most effective dosages and most bioavailable form of each ingredient:

  • 8mg of Boron (Boosts Free Testosterone By 28%) (NCBI, 2015)
  • 50mcg (2000IUs) of Vitamin D3 (Boosts Testosterone By 25%)
  • ZMA (Boosts Free Testosterone By 33.4%) (ASEP, 2000)
  • 2352mg of D Aspartic Acid (Boosts Testosterone By 30% To 60%) (PUBMED, 2017)
  • 40mg of 4:1 Fenugreek Extract (Equivalent To 160mg of Fenugreek) (Boosts Free Testosterone By 46% to 98%) (PUBMED, 2016; PUBMED, 2017)
  • Korean Red Ginseng Is A Natural Aphrodiziac That Increases Libido & Fertility. Red Ginseng Works As A Natural But Weaker Alternative To Viagra – Relaxing Muscles & Increases Blood Flow To The Genital Area (Live Science, 2011)
  • Nettle Leaf To Significantly Reduce Inflammation (Root Cause Of Low Testosterone) (HEALTLINE, 2018)
  • Bioperine® (Patented Black Pepper Extract) enhances nutrient absorption by at least 30% (BIOPERINE.COM, 2021), making the ingredients inside Testogen more potent.

Based on how effective each ingredient inside Testogen is, it should significantly increase both your Free & Total Testosterone.

I’ve utilized Testogen alongside a Testosterone boosting diet to triple my Testosterone levels from 370ng/dL (low Testosterone) to 934ng/dL (high Testosterone).

Testogen works because its ingredients target the major causes of low Testosterone (excess inflammation, vitamin deficiencies, high blood sugar and high Estrogen levels respectively).

No other all in one Testosterone booster on the market does that.

Furthermore, it contains no artifical colours or preservatives.
