Review of the TestoPrime Ingredients

TestoPrime contains a number of ingredients that are intended as natural testosterone boosters. While testosterone boosting supplements are sometimes compared to steroids or synthetic testosterone, the effects of the ingredients of TestoPrime are more complicated.

Rather than directly increasing testosterone levels, the supplement supports your body’s health so that you’re more likely to produce healthy levels of testosterone. Scientific research links ingredients to effects, though research is often preliminary.

As a result, while TestoPrime and other testosterone boosting supplements can be helpful in building muscle strength or increasing sex drive, and more, their effects may vary a great deal depending on the person.

D-Aspartic Acid

D-aspartic acid is a naturally occurring amino acid, connected to both brain function and the reproductive system.

In studies, it seems that d-aspartic acid can lead to a direct increase in testosterone levels. Among other functions, it prompts the production of luteinizing hormone (LH), which is one of the ingredients needed to increase testosterone production [1].

Panax Ginseng

Panax ginseng, or Asian ginseng, has been used as an herbal remedy for centuries. It’s one of the natural ingredients in the TestoPrime testosterone supplement, as well as many other testosterone boosters and supplements. Traditionally, ginseng was supposed to reduce stress and support increased blood, as well as being used as a male fertility treatment.

Unfortunately, despite its long use, there isn’t much high-quality science regarding ginseng’s effects. In particular, there’s no hard evidence that it affects testosterone. However, it may help lower blood sugar and improve metabolism [2]

Vitamin B6

While there may be no direct link to testosterone levels, deficiencies in vitamin B6 have been linked to low energy levels, decreased immune system, and reduced bone density. Taking it as part of a supplement like TestoPrime testosterone booster may help you avoid all those problems and stay healthy.

Vitamin B6 is also involved in amino acid metabolism, which can be part of building new muscle. You can’t really get too much B6, so there’s no downside to getting more. However, you should be getting enough if you’re eating a healthy diet [3].

Ashwagandha Extract

Another of the all-natural ingredients TestoPrime contains that has been used traditionally for centuries, ashwagandha may have a number of health benefits. Scientific research has linked it with decreases in the stress hormone cortisol, which can affect weight loss, mood, and have a range of health benefits. It’s also a common ingredient in fat burners for men and other bodybuilding supplements.

Additionally, the ratio of testosterone to cortisol is thought to be significant in many reactions. If there’s more cortisol, the existing testosterone may have less of an effect. Ashwagandha’s ability to reduce cortisol levels may tip the balance in testosterone’s favor.

As a result, while it may not directly affect testosterone production, it’s possible ashwagandha may make existing testosterone more effective [4] [5].



Fenugreek is a spice used in some Asian dishes, as well as in many testosterone boosting supplements. Its inclusion in TestoPrime may be linked to some limited research that showed it increased testosterone levels.

Additionally, there’s a possibility some compounds in fenugreek prevent existing testosterone from breaking down. Fenugreek may also provide some of the precursors, or raw materials, for creating more testosterone. In some studies, men taking fenugreek supplements both lost weight and showed improvement in resistance exercises. However, at this point it’s difficult to say who will benefit and how much [6].



TestoPrime contains zinc, an essential mineral that can also be found in many testosterone supplements. While it may not necessarily boost testosterone production, a zinc deficiency can lead to a drop in testosterone, which supplementation can aid in avoiding. Zinc is also important to the health of the testes and male reproductive system, even down to strengthening the membrane of sperm.

It also has been linked to a boosted immune system, as well as healthy metabolism and energy levels. For older folks, it may also help reduce the loss of muscle associated with aging.

However, it’s important to note that taking high doses of zinc regularly may also cause problems. Too much zinc had been linked to reduced immune function, copper deficiencies, and urinary problems. The 40mg of zinc included in each serving of TestoPrime is the recommended upper limit for adults each day [7] [8].

Vitamin D

Vitamin D is another ingredient in TestoPrime that’s vital for health. It’s also common for many people to have low levels of vitamin D. The most well-known way of increasing vitamin D is standing in the sun, though many foods are also now fortified with it, as well. Older folks, in particular, are at risk of having low vitamin D.

Taking vitamin D may not boost testosterone production directly. However, a deficiency can lead to a whole range of problems, including lowered energy levels, higher levels of body fat, and potentially erectile dysfunction.

Supplementing the lack can help with weight loss (it’s a common ingredient in fat burner supplements), increased blood flow, and retaining muscle strength. Healthy amounts of vitamin D can also help protect the cardiovascular system [9].

Pomegranate Extract (40% Ellagic Acid)


Pomegranate extract is another of the natural ingredients with a range of potential health benefits. It’s been associated with benefits like increased blood flow and lowered blood pressure. There’s not a lot of evidence for those claims, however. In some Asian traditions, the pomegranate is associated specifically with fertility and good luck.

Its potential to boost testosterone production naturally may rely on its antioxidant effect. Oxidative damage can particularly affect the testes, which produce most testosterone. Antioxidants may therefore have a protective effect [10].

Note that a small number of people have allergic reactions to pomegranates and might want to avoid this supplement as a result.

Vitamin B5

It is fairly easy to get all the vitamin B5, also known as pantothenic acid, you need from your diet. Supplementing B5 has been linked to lower blood cholesterol levels, which can impact the immune system and levels of body fat. While it doesn’t necessarily boost testosterone levels directly, it is necessary for general health and supporting healthy testosterone levels.

TestoPrime contains 8 mg a serving, which is more than you need in a day. However, you can’t really take too much [11].

Garlic Extract


Garlic can do more than make food tasty. It has been used as a traditional remedy all over the world for centuries, and animal studies show that garlic extract may increase serum testosterone levels [12].

The ingredient also has some antioxidant properties, which may be the most relevant benefit for TestoPrime. Antioxidants may help protect testosterone-producing cells. Additionally, garlic can help to lower cholesterol levels a small amount.

There is also some evidence garlic can help lower blood pressure and enhance blood flow. Improvements in those areas can also lead to improved sexual function and perhaps even increased sexual drive [13].

Black Pepper Extract (95% Piperine)


Piperine is another ingredient that has an ambiguous relationship with testosterone production. It has generally been found to increase the bioavailability of other ingredients. As a result, more of the nutrients will be absorbed and used by your body, rather than passing through, to increase the overall effectiveness of the supplement.

Piperine has also been found to increase serum testosterone production in pubescent rats, assisting in the development of Leydig cells, which is where most testosterone is created [14]. Piperine also increased the production of luteinizing hormone, which is important in signaling your body to produce more testosterone.

Finally, piperine has some antioxidant properties, which as we’ve mentioned can help protect against oxidative damage. However, in other studies the use of piperine damaged the testes of older rats and lowered testosterone levels [15]. As with many supplement ingredients, we don’t fully understand why it has the effects it does.

Green Tea Extract (70% Catechins)


Green tea extract is another popular natural ingredient in many supplements. Green tea contains some amount of caffeine, which can help you lose weight and have more energy. Both of those benefits may positively affect sex drive.

While some studies show green tea can improve sperm parameters, there is also evidence that tea and the catechins it contains interfere with testosterone production and may lower testosterone levels. Most research is based on studies with rats rather than humans, so it’s impossible to make definitive statements [16] [17].

How To Take TestoPrime

One dose of TestoPrime testosterone boosting supplements is four capsules, taken once a day before breakfast. It’s recommended that you do not take the supplement immediately after eating, as it may cause some stomach upset.

Supplements like TestoPrime work best when taken regularly, as the effects of the ingredients are allowed to build up over time. TestoPrime suggests trying the product for at least 30 days. It may not be wise to continue taking it indefinitely, however. Some ingredients have been linked to negative effects when taken for long periods.

You may sometimes see it recommended to double the dosage for supplements like TestoPrime, with the goal of multiplying the benefits. However, that’s usually not the result. A single dose contains doses that are generally toward the upper limit of what’s recommended. At best, the additional nutrients are passed through without being absorbed. At worse, you’re increasing your chances of side effects.

TestoPrime Side Effects

While TestoPrime claims its all-natural ingredients mean the product is safe, there are risks whenever taking a supplement. Even taking too much of the minerals and nutrients required for health can lead to negative effects. TestoPrime supplement contains the upper amount for a daily dose of zinc, for example, which taken consistently over a long period of time may increase the chances of urinary problems later in life.

Other ingredients may also pose similar problems.

  • Garlic extract side effects include heartburn and nausea.

  • Panax ginseng has been associated with problems sleeping, effects on blood sugar, headache, and loss of appetite.

  • Fenugreek may cause diarrhea, nausea, and has the potential to cause a large drop in blood sugar.

  • D-aspartic acid can impact metabolism and shouldn’t be taken continuously over a long period.

  • Pomegranate extract may also cause stomach upset.

TestoPrime Interactions with Other Supplements

It may be wise to avoid TestoPrime if you’re taking certain other medications, or have some specific conditions. While it is a natural supplement, that doesn’t mean it’s free from potential complications.

Some important contradictions to be aware of include:

  • Garlic extract may increase the risk of bleeding and may not mix well with blood-thinning medications. It may also interfere with the effectiveness of some drugs.

  • Panax ginseng may interact with high blood pressure medications, statins, and some antidepressant medications. You may want to avoid ginseng while pregnant.

  • Zinc can inhibit the absorption of some antibiotics.

Always remember to consult your doctor before starting a new supplement.

How Well Does TestoPrime Work?

The effects of a natural testosterone booster like TestoPrime can vary a great deal depending on a number of factors, such as existing testosterone levels and your current level of health. While TestoPrime supplement is focused on increasing the level of testosterone hormones, it has the potential to improve your health generally, with potential benefits to energy levels and sex drive.

Promises of TestoPrime

TestoPrime is a testosterone boosting supplement, which means it doesn’t actually contain any testosterone itself. Instead, it offers a safe way to increase natural testosterone production through the use of herbal remedies and essential nutrients. It claims benefits as wide-ranging as weight loss, increased sex drive, and clearer thinking. Some of those claims are on firmer ground than others.

Mental and Physical Boost

A testosterone deficiency can lead to a range of problems, including lowered energy levels, difficulty focusing, loss of muscle strength, and a tendency to gain weight. Low testosterone is natural in some cases, particularly for older men, but boosting it within a healthy range can address many of those problems. In particular, ingredients like d-aspartic acid may help with that directly.

It’s difficult to think clearly when you’re stressed. Ashwagandha root may have the effect of reducing stress, both helping you to relax and reducing levels of the stress hormone cortisol. Not only does it help take off the pressure, it allows your current testosterone levels to be more effective in many cases.

Other ingredients can pick up the slack in other ways. Green tea extract, for example, may provide more energy and assist with weight loss. Vitamin D is essential for maintaining lean muscle mass and many people don’t get enough in their daily lives. Together, the effects may offer a boost in both physical energy and mental clarity.

Improved Sexual Drive

Testosterone hormone levels can have a direct impact on sexual function, with low testosterone potentially causing erectile dysfunction (ED), among other problems. For better or worse, many men’s self-esteem is linked to their sexual performance, and low testosterone levels can even directly affect a man’s sex drive. In addition to potentially boosting testosterone production in several ways, TestoPrime may address problems of sexual motivation and performance indirectly.

For example, garlic and vitamin D may be able to address ED by improving blood flow and addressing cardiovascular problems. Both high blood pressure and cardiovascular disease are linked to an increase in ED, as well as lowered sexual drive.

Losing weight, with the help of green tea extract and other ingredients, can help control estrogen production and promote healthy testosterone production. Being overweight or even obese can seriously impact testosterone levels, throwing hormone levels generally out of balance.

However, those problems are usually reversible when the cause is addressed. TestoPrime may help you lose weight and improve your overall health, and your sex drive may get a healthy boost as well.

Optimized Metabolism

Excessive weight gain is associated with low testosterone, perhaps even causing genuine testosterone deficiency. It’s a vicious cycle, with higher levels of body fat causing low testosterone, and low T making it easier to put on weight. Moreover, it’s a cycle that’s easier to fall into as you age. Weight gain can also cause lowered energy levels, loss of muscle mass, and impact sexual function [18].

Fortunately, helping your body return to a healthy metabolism can address many of those problems. It’s important to address deficiencies in nutrients like d-aspartic acid, vitamin B6, vitamin D, and other ingredients found in a natural testosterone booster like TestoPrime. Taking advantage of higher energy levels to exercise can also help with weight loss.

By combining TestoPrime with a healthy diet and exercise, you can escape the cycle, finding a healthy weight and metabolism, as well as healthy testosterone levels.

How to Get the Most Out of TestoPrime

Testosterone support supplements have to be used while also eating a healthy diet and exercising. Particularly if the benefit you’re looking for is muscle growth, TestoPrime may help you achieve your desired results. You may get more out of your workouts and bounce back faster, but you’ll still have to be lifting weights and doing cardio.

It’s best to give the supplement a few weeks to work, with TestoPrime recommending at least 30 days. If you don’t see benefits at that point, you can return it for a refund. However, you may not want to continue taking it forever. Some ingredients have been linked to health problems when taken in high doses for prolonged periods.

Is TestoPrime Safe?

In general, TestoPrime and other testosterone boosters are safe. The majority of the ingredients, like vitamin D and green tea extract, are taken from natural and herbal sources. Some are even essential for good health. Additionally, the supplement may help address low testosterone levels by supporting overall health.

However, even essential nutrients can have negative effects if you take too much, or take too much for too long. Ingredients like D-aspartic acid and zinc shouldn’t be taken long term, and there are also potential interactions with medications or even allergic reactions to take into account.

Be conscious of the supplement’s effects on you. If the effects are unpleasant, it’s unlikely to be benefiting you.

TestoPrime Reviews: What Do Users Say?

TestoPrime Review: Common FAQs

Have questions about TestoPrime, or dietary supplements in general? See if we answer them below.

Is TestoPrime FDA-Approved?

TestoPrime testosterone supplement has not been specifically evaluated by the FDA. Supplements like TestoPrime don’t have to go through the same testing and certification process as prescription drugs. Additionally, TestoPrime’s claims to boosting low testosterone haven’t been tested either.

Instead, with dietary supplements, individual ingredients are evaluated for safety. For example, it’s been established that it’s safe to use green tea extract in a nutritional supplement. The same is true of other ingredients.

Does TestoPrime Increase Testosterone?

It’s possible that TestoPrime stimulates testosterone production naturally. However, there’s no guarantee that it will affect your body’s testosterone levels at all. The supplement provides some compounds that can encourage your body to produce healthy testosterone levels. Other ingredients may help prevent weight gain or aid in retaining lean muscle mass, both of which can positively impact low testosterone.

As with any supplement, it will be most effective if it’s addressing a lack. As an example, imagine you are suffering from a vitamin D deficiency and experiencing several health effects as a result. Supplementing vitamin D will help resolve those negative health effects.

On the other hand, if you’re already getting sufficient vitamin D, getting more may not help. Likewise, if you’re getting sufficient nutrients in your diet, supplementing may not have a dramatic effect.

How Long Should I Take TestoPrime?

Supplements work best when taken over a period of time, so you can expect to wait at least a few weeks before TestoPrime starts to impact your body’s natural testosterone production. You may not be able to directly measure testosterone levels. However, you may feel more energy or feel like a workout results in more muscle growth.

Take caution if you plan on taking TestoPrime long term. Some of the ingredients can cause health problems if taken in large doses over a longer period of time. For example, taking D-aspartic acid regularly can negatively impact your metabolism and kidney function. Check with your doctor if you have any concerns.

For the most part, a healthy diet and exercise are all most people need to maintain testosterone levels. While some people have a genuine testosterone deficiency, the healthiest way for many men to address low testosterone is managing diet and increasing lean muscle mass through exercise.

However, a boost is often helpful. Products like TestoPrime may be able to provide that boost, though it’s important to find one that supplies the nutrients and benefits that match your needs.

TestoPrime Review: Final Verdict

By their nature, supplements work best when they make up for something that is lacking. If you already have healthy amounts of testosterone, as well as other ingredients like vitamins B5, B6, and D, then you may see fewer benefits when taking TestoPrime. On the other hand, you may find it provides the nutrients, energy, and drive you’re lacking. You can try it out with little risk, due to their money-back guarantee.
