Testosterone Booster Ingredients

As you will discover when you begin to look for the best testosterone boosters on the market, there are a wide range of ingredients. Some are effective, others are less than ideal. Some may sound like they would be a great idea but won’t produce much more than a great marketing campaign. It’s important to understand that ingredients are important when it comes to testosterone boosters because the perfect combination will help you achieve the results you’re looking for: an increase in testosterone production within the body. Let’s look at some of the most common ingredients found in testosterone boosters, what they are supposed to do, and whether they actually work.


Avena Sativa

This supplement may sound obscure, but it’s just the scientific name for oats. While eating oatmeal provides its own bodybuilding benefits, this extract from oats provides testosterone-boosting effects. Avena sativa extract has large amounts of avenocosides, the active component that boosts testosterone. This supplement is saponin-based, meaning its benefits come from plant chemicals. It works by releasing bound testosterone, increasing your levels of free testosterone, which supports muscle building.

For best results: Seek out products that provide a 10 to 1 ratio of Avena sativa extract, and take 100-300 mg per day. Split your intake (especially at the higher end) over 2 to 3 doses per day. After you’ve taken Avena sativa for up to eight weeks, give your body a break by taking 2 to 4 weeks off.

D-Aspartic Acid

When an individual consumes D-Aspartic Acid, it reacts with the brain and that stimulates an increased production of lutenizing hormone, commonly referred to as LH. It is this hormone that moves to the testes to stimulate the production of free testosterone, which is vital for many facets of the male body, including energy levels, sex drive, and even stamina and strength.

For best results: Take 2g-3g of D-Aspartic Acid per day. Scientific findings that DAA will boost testosterone 30%-40% and is important for men who are seeking to regain their vitality and energy as well as libido. You will gain tremendous benefits from supplementing their diet with DAA.


DHEA (dehydroepiandrosterone) is the most abundant steroid hormone in the body, and is a direct precursor of testosterone. DHEA levels decrease with age, an 80 year old person will have only 10% of the DHEA produced during peak years or early adulthood. Thus, DHEA supplementation can be particularly helpful to manage low testosterone levels in both men and women. Patients supplementing with DHEA for low testosterone will notice improvement in the testosterone levels but need to be monitored closely.

For best results: DHEA is available as capsules, tablets and injections with effective daily doses ranging from 25-200 milligrams daily.


EFAs are primarily referred to as Omega-3 and Omega-6. Other types of fatty acids – Omega-7 and Omega-9 – are also important – however, the body can produce them in the presence of the essential EFAs. Without adequate fat in your diet, your body will not be able to produce testosterone and many other hormones. Essential fatty acids like those found in fish oil and flax seed oil are beneficial for testosterone production, anti-inflammatory effects, and cell membrane health.

For best results: Research shows that to maximize muscle growth, decrease body fat and improve general health, men may consume between 3 and 3.5 grams of EFAs from all sources (food and supplements) daily; women may consume between 2.5 and 3 grams from all sources daily.

Epimedium (Horny Goat Weed)

Epimedium is grown in Asia and the Mediterranean region. Traditional use of epimedium is for treating fatigue and boosting sex drive. Epimedium is thought to work via modulation of cortisol levels (the primary stress hormone). Under conditions of high stress, testosterone levels decrease and cortisol levels increase causing fatigue and a depressed sex drive. Epimedium may assist in bringing cortisol levels back into normal range, and thereby testosterone levels as well. It is also thought to help restore normal metabolism and energy levels.

For best results: Typical dosage levels are 250 mg to 1,000 mg per day in divided doses standardized for 10% icariin.


This herb is a dynamic testosterone booster, allowing your body to balance and regulate this key male hormone. That’s because fenugreek passes through your liver before it affects your T levels. Once your liver is on board, the saponins (plant chemicals) in fenugreek help increase your body’s free testosterone. This is the type of “T” that your body can use to support muscle building, and fenugreek helps you make the most of your body’s natural levels.

For best results: Take in 500-2000 mg of fenugreek per day, but you should balance this with Tribulus terrestris (discussed below), making sure that you don’t take in more than 2000 mg per day combined, as they work in similar ways.


Forskolin comes from the root of the Coleus forskohlii plant. It’s been used for medicinal purposes for centuries, and it’s been used as a fat burner over the past decades. But forskolin is also a testosterone booster. Forskolin works by activating an enzyme, adenylate cyclase, known to increase levels of cyclic adenosine monophosphate (cAMP), which helps regulate energy systems. Increased levels of this enzyme in Leydig cells (found near the testicles), stimulate testosterone production.

For best results: Look for products that are standardized for 20-50 mg per dose, and take this two to three times per day for a total of up to 150 mg of forskolin per day. Note that the amount of forskolin may need to be multiplied by the percent of the extract to compare dosages from one product to another (e.g. 250 mg of a 20% forskolin extract yields 50 mg of forskolin).


Ginseng is a powerful nutrient that drives many healthful physiological functions. Included in the list is an increase in libido and testosterone. Ginseng directly stimulates the central nervous system and gonadal tissues, and can help facilitate erections in males. Ginseng also contains ginsenosides that increase the conversion of arginine to nitric oxide, which helps build muscle mass.

For best results: Look for products that provide 40–50 milligrams of ginseng extract, and take two doses per day.

Mucuna Pruriens

Mucuna Pruriens, also known as Velvet Bean and Cow-itch, is most known for the compound, L-Dopa. The L-Dopa in Mucuna Pruriens is the precursor to Dopamine, a neurotransmitter. Because Dopamine prevents prolactin from destroying Testosterone, Mucuna Pruriens in sufficient amounts helps boost Testosterone.

For best results: Look supplements that contain Mucuna Pruriens that is standardized to 15-50% L-Dopa or L-Levodopa

Oyster Extract

Oyster extract is a type of health supplement derived from the essences of oysters, a shellfish. The extract is meant to amplify the nutritional and health benefits of oysters. More so among men who are suffering from low testosterone related health issues.

Oyster extract is a rich source of zinc and vitamin D that stimulate the development and secretion of testosterone in the body. Regular supply of zinc and vitamin D in men can lead to improved muscle growth and increased libido.

Stinging Nettle

Stinging nettle extract is derived from the leaves and root of the nettle plant. The six isolectins found in nettle are shown to inhibit testosterone from binding with sex hormone binding globulin, or SHBG, which is responsible for maintaining hormonal balance in your body. Once excessive testosterone binds to SHBG, it is not bioavailable to be utilized by your body, thus causing a decrease in free testosterone levels. Free testosterone is testosterone readily available to be used by your body.

Tongkat Ali

While this may sound like a formidable pro bodybuilder, boxer or MMA fighter, it’s merely a rainforest plant. However, it still packs quite a punch, boosting testosterone levels by releasing bound testosterone from SHBG. Tongkat ali (aka Eurycoma longifolia) also stimulates the Leydig cells of your testes, which boosts testosterone production. So tongkat ali provides a one-two hit—setting free what you already have while increasing production of more testosterone.

For best results: Take 100-300 mg in the morning; about 30 minutes before training, and before bed. As with other T boosters, take this supplement for up to 8 weeks, and then take a 2- to 4-week break.

Tribulus Terrestris

This herb, which grows in both Asia and North America, has been used as an aphrodisiac for centuries—no shocker, then, that it boosts your testosterone levels, right? The supplemental form of Tribulus terrestris increases your body’s level of luteinizing hormone (LH), which encourages testosterone production. To get the most from tribulus supplementation, you should seek out products that contain 80% or higher total saponins with 40% prodioscin.

For best results: Take 500-2000 mg per day, divided over two to three doses, taking one about an hour before workouts. After you’ve supplemented tribulus for up to eight weeks, you should give your body break, cycling off for 2 to 4 weeks. Keep total consumption of tribulus and fenugreek (above) within this range, as they work in similar ways.

Vitamin D

A vastly underrated testosterone booster, this fat-soluble vitamin provides numerous benefits. When vitamin D is plentiful, studies show that it increases strength. One of the ways it does so is by being converted in your body into an important steroid hormone (1,25-dihydroxyvitamin D). When your body has an abundance of vitamin D, it signals your genes to increase muscle strength and growth. Supplementing vitamin D helps maximize this potential.

For best results: Take 1000 IU of vitamin D3 2 to 3 times per day. This is the most important form of vitamin D for building muscle tissue.

Zinc and Magnesium (ZMA)

ZMA is a combination of zinc monomethionine aspartate, magnesium aspartate and vitamin B6. Supported by two studies, the data on this product shows total and free testosterone increases of up to 33% in athletes taking ZMA. There were also corresponding increases in strength and power measurements. Zinc and magnesium play a role in over 500 metabolic reactions in the body while vitamin B6 is very important for muscle protein synthesis.

For best results: The normal dosage for ZMA is 30 mg of zinc, 450 mg of magnesium, and 10.5 mg of B6 taken at night.



Low T. level is a usually tell-tale sign that the brain and the testicles aren't properly communicating with each other. It also occurs when the body is physically unable to produce normal levels of testosterone. A male that continually has low T. levels could end up with a medical condition. known as hypogonadism.
