Testosterone is the primary sex hormone in males. It plays a key role in muscle and bone growth, strength, sex drive, and sperm production.

Around age 30, a man’s testosterone levels start to decline by about 1% each year naturally. Low testosterone, also known as low T or hypogonadism, affects around 40% of men over the age of 45.

Low testosterone levels can lead to reduced sex drive, fatigue, erectile dysfunction, moodiness, and loss of muscle mass.

Fortunately, several medical treatments are available to help increase testosterone levels. There are also over-the-counter testosterone boosters that may help increase testosterone production. 

This article will take a look at the best testosterone booster supplements on the market today. It will also discuss whether testosterone boosters are safe and work.

Best Natural Testosterone Booster On The Market In (July. 2024)

Top 5 Best Natural Testosterone Boosters

TestoGen

TestoGen is a testosterone-boosting supplement that contains a blend of vitamins and natural ingredients that may work to boost testosterone production.

  • Natural ingredients
  • No prescription needed
  • Stimulant free
  • Research-backed ingredients
  • 100-Day money-back guarantee
  • No third-party testing

  • Natural ingredients

  • No third-party testing

TestoGen is a blend of natural vitamins, minerals, and other natural ingredients that may help improve testosterone production. It’s available online, and no prescription is required.

According to their website, TestoGen is designed for males over the age of 18 struggling with common signs of low testosterone. They promise instant, short-term benefits but state that it may take two weeks to feel the full effects.

The company itself is based out of the United Kingdom but ships worldwide. All of their supplements are manufactured in FDA-approved facilities. However, it does not appear their products carry a third-party seal. TestoGen pills are gluten-free, chemical-free, soy-free, and caffeine-free.

A one-month supply costs $60 and ships free to anywhere in the world.

If you’re not satisfied with your purchase, TestoGen offers a 100-day money-back guarantee.

Ingredients

Similar to TestoPrime, TestoGen’s main ingredient is D-aspartic acid. However, it has slightly more than TestoPrime at 2,352 milligrams.

Here’s a look at the other key ingredients in TestoGen.

Magnesium

TestoGen contains 200 milligrams of magnesium, which is important for many functions in the body. A review[1] from 2014 found that men with testosterone deficiency and magnesium deficiency may benefit from taking magnesium to improve physical performance. Testosterone production was higher in those exercised males who took magnesium.

Red Korean Ginseng

Another key ingredient found in TestoGen is Red Korean ginseng, also known as Panax ginseng or Asian ginseng. A meta-analysis[2] from 2018 found that Red Korean ginseng may improve erectile function among men with erectile dysfunction. Animal studies[3] also suggest that Red Korean ginseng may stimulate nitric oxide production, causing smooth muscles to relax and improving blood flow to the penis.

Fenugreek Extract

TestoGen has 40 milligrams of fenugreek extract. While we need more research, some studies suggest it may improve sexual health and help with boosting testosterone levels. For example, one study[4] found that 500 milligrams of fenugreek led to improved upper and lower body strength in men who regularly strength trained.

Another study[5] gave 60 healthy men 600 milligrams of fenugreek to assess sex drive and strength changes. At the end of the study, the men experienced increased strength, energy, and well-being. There also was a significant increase in sex drive and orgasm.

Other ingredients in TestoGen include zinc, vitamin D3, boron, nettle leaf extract, vitamin B6, vitamin K1, and BioPerine, or black pepper.

Dosage

Users should take 4 Testogen capsules daily, 20 minutes before breakfast for best results.

TestoPrime

TestoPrime is formulated with research-backed ingredients that may support healthy testosterone levels.

  • No prescription required
  • 100% lifetime money-back guarantee
  • Soy-free
  • Vegan
  • Manufactured in an FDA-approved facility
  • Free shipping
  • Pricey

TestoPrime is formulated with research-backed ingredients that may support healthy testosterone levels.

  • No prescription required
  • 100% lifetime money-back guarantee
  • Soy-free
  • Vegan
  • Manufactured in an FDA-approved facility
  • Free shipping
  • Pricey

TestoPrime is a testosterone booster that is available online with no prescription required. It is designed for users over the age of 18 who feel as if they need an extra boost to reach healthy testosterone levels.

This supplement is made with all-natural ingredients, and — according to the company’s website — users will begin to experience the benefits of TestoPrime right away.

It is manufactured in FDA-approved facilities in the United States and the United Kingdom. The company also reports it utilizes third-party testing. However, there are no lab reports published on their website at this time.

Unlike other companies on the market, TestoPrime does not require a monthly subscription and accepts one-time payments. A one-month supply costs $60 and ships free. Discounts are available for bulk purchases. If you buy in bulk, you’ll also get an e-book that highlights foods and lifestyle changes you can make to naturally improve testosterone levels.

One thing we like about TestoPrime is its generous return policy. If you’re not satisfied with your results after using the product, they offer a 100% no questions asked, lifetime money-back guarantee. However, they claim less than 2% of men have been unsatisfied with the results.

The product is also vegan, soy, and non-GMO (genetically modified organisms). 

Ingredients

Here’s a look at the main ingredients that you’ll find in TestoPrime:

D-aspartic Acid, 2,000 milligrams

D-aspartic acid is an amino acid that is involved in the synthesis and release of testosterone.  One review[6] from 2017 examined 23 human studies and four animal studies to establish a relationship between the ability of  D-aspartic acid to aid in stimulating natural testosterone production.

Researchers believe D-aspartic acid acts on the hypothalamus, which stimulates the release of gonadotropin-releasing hormone. The gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete a luteinizing hormone, which may increase testosterone production. However, positive results were more substantial in animal studies and less consistent in humans.

TestoProme contains 2,000 milligrams of D-aspartic acid.

Green Tea

Green tea extract is chock-full of antioxidants and may promote weight loss. One study[7] found that men who consumed green tea extract before exercising burned 17% more fat than those who did not. 

KSM-66® Ashwagandha Extract

Ashwagandha has been used for centuries in Ayurvedic medicine to increase longevity and help the body deal with physical and mental stress. Studies[8] show that 300 mg of high-concentration, full-spectrum ashwagandha extract can safely and effectively reduce stress and improve quality of life. 

Another study[9] found that men who took ashwagandha experienced a 17% increase in testosterone levels and a significant increase in sperm concentration.

TestoPrime contains 668 mg of high-quality KSM-66® Ashwagandha extract.

Other ingredients in TestoPrime include Panax ginseng, fenugreek, zinc, B vitamins, and vitamin D.

Dosage

TestoPrime is designed to be used daily. According to the manufacturer, users should take four capsules every morning before breakfast.

TestoFuel

TestoFuel is a natural testosterone supplement designed for women and men. It contains ingredients that may help your body produce testosterone.

  • Worldwide shipping
  • Stimulant free
  • No prescription required
  • Natural ingredients
  • Designed for bodybuilders
  • No third-party testing
  • Limited return policy

TestoFuel is made for men and women over the age of 18 who are looking to increase lean muscle mass. It’s designed for bodybuilders and athletes looking to level up their performance in the gym. The company also states older men who want to boost their testosterone levels may benefit from TestoFuel.

The supplement is produced in certified facilities in the United States and the United Kingdom. If you live in the United States or Canada, returns are accepted within 30 days of purchase. However, products must be shipped back unused and unopened. 

According to their website, users will need to take TestoFuel consistently for two months to see the most benefits. 

A one-month supply of TestoFuel is $65, but you can save up to 30% if you buy in bulk. 

Ingredients

Similar to the other products mentioned above, TestoFuel’s main ingredient is 2,300 milligrams of D-aspartic acid. Its other main ingredients are vitamin D and oyster extract. 

Vitamin D, 4,000 IU

TestoFuel contains 4,000 international units (IU) of vitamin D. Vitamin D provides many health benefits and is important for building strong bones and supporting a robust immune system. Although research is mixed, vitamin D may also help testosterone production. The Daily Value for individuals 18-70 is 600 IU.[10]

For example, one study[11] found that men who took 3,332 IU of vitamin D experienced significant improvements in testosterone levels.

However, another study[12] found that vitamin D supplementation did not affect testosterone levels in middle-aged, healthy men with normal baseline total testosterone levels. 

Oyster Extract

Oysters are one of the highest dietary sources of zinc there is. Zinc plays many important roles in the body, including supporting testosterone production. Having a zinc deficiency is rare in the United States, but it can lead to low testosterone.

One animal study[13] found that taking oyster extract may improve reproductive function in zinc-deficient mice.

Other ingredients you’ll find in TestoFuel are Asian red ginseng, fenugreek, magnesium, and vitamin B6.

Dosage

The manufacturer recommends taking one pill four times daily with meals to help your body better absorb the blend. However, they state that users can take two pills twice daily if it is more convenient. TestoFuel states that taking more than one capsule can cause an upset stomach due to the high quantity of D-aspartic acid.

Life Extension DHEA

Life Extension is a well-known supplement company that sells DHEA, which may help support testosterone production.

  • Affordable
  • Research-backed
  • Third-party testing
  • Natural
  • Gluten-free
  • Banned in professional sports

Life Extension is a well-known supplement company that sells DHEA, which may help support testosterone production.

  • Affordable
  • Research-backed
  • Third-party testing
  • Natural
  • Gluten-free
  • Banned in professional sports

Life Extension is a well-known supplement company that carries a variety of vitamins, minerals, and other supplements.

The DHEA supplement sold by Life Extension comes in a 25-milligram gluten-free pill. It’s very affordable at just over $7 for a 60-day supply. It can be purchased via their website. It also is available on Amazon with free shipping for Prime members.

A third party tests all products sold by Life Extension.

Ingredients

Dehydroepiandrosterone, or DHEA for short, is a hormone that’s mainly produced by the adrenal glands and contributes to male traits. It’s one of the most common supplements recommended to improve testosterone levels because it helps produce other hormones, including testosterone.

DHEA levels naturally peak in early adulthood and begin to decline slowly as we age. Although we need more studies to better understand how DHEA works to reverse aging and improve physical performance, some studies appear promising.

One study[14] found that DHEA successfully improved testosterone levels in both men and women. People who took over 50 milligrams per day experienced a significant increase in testosterone levels.

However, other studies[15] suggest it may not improve levels and call for better-organized trials to evaluate DHEA’s effectiveness at enhancing testosterone levels. There’s also inconsistent evidence[15] that it may promote bone health and reduce fat mass in older men.

It’s important to remember that DHEA is banned in professional sports. 

Dosage

According to the packaging, users should take between one and three pills per day and have labs checked after three to six weeks to optimize individual dosing.

Prime Male

Prime Male is made with 12 research-backed ingredients that may help boost testosterone production

  • Natural ingredients
  • Vegan
  • May support natural testosterone production
  • No prescription required
  • May support healthy energy levels
  • No third-party testing
  • Limited return policy

Prime Male is a United States-based brand whose supplement contains a potent blend of 12 ingredients designed to improve testosterone levels. 

Their products are manufactured in an FDA-approved facility and according to current Good Manufacturing Practices (cGMP) to ensure federal regulations are being followed regarding quality.

A one-month supply costs around $69, and discounts are offered for bulk purchases. Prime Male accepts returns within 30 days for United States customers and within 14 days for the rest of the world. However, products must be returned unopened and unsealed. 

Ingredients

Similar to the other products we’ve discussed, the main ingredient in Prime Male is D-aspartic acid. 

It’s also got black pepper, which is known for its ability to help increase absorption of other nutrients. Prime Male is also formulated with vitamin B6, which helps the body turn food into energy.

Boron

Additionally, it has 5 milligrams of boron. Some studies suggest that boron supplementation in both men and women may increase testosterone levels. One study[16] gave men 6 milligrams of boron. After one week, there were significant increases in free testosterone levels and decreases in markers of inflammation. 

Overall, boron appears to be somewhat effective, but we need more trials to investigate potential benefits further.

Luteolin

Another unique ingredient in Prime Male is luteolin. One animal study[17] from 2020 found that luteolin increased progesterone and testosterone production in aging rats. However, research is limited on its effectiveness in humans.

Other ingredients in Prime Male include Korean red ginseng, ashwagandha, magnesium, vitamin D3, and vitamin B6.

Dosage

According to the package, users should take one pill with a meal or snack four times per day.

Do Testosterone Boosters Work?

Although testosterone supplements may have ingredients proven in clinical studies to help boost testosterone levels, it’s important to remember the FDA does not evaluate them for quality or effectiveness.

Today, most products sold on the market have slightly different active ingredients at different dosages. This marketing approach means effects can vary depending on the testosterone booster supplement you buy.

One study[18] from 2019 looked at the effectiveness of the main ingredients in the top testosterone-boosting supplements sold on Amazon. Researchers found that out of 37 human studies, around 30% saw improvements in testosterone levels after consuming ingredients commonly found in testosterone-boosting supplements.

Another study[19] found that 90% of testosterone boosters claimed to “boost T.” However, only 24.8% had data to support these claims. What’s more, 10.1% contained compounds that may actually harm T levels.

If you choose to buy an over-the-counter (OTC) testosterone booster, it’s essential to select a high-quality product to increase the chances of it working.

When Should We Use Testosterone Pills?

Most healthy individuals who are naturally producing testosterone don’t need testosterone pills. If you suspect you have low testosterone levels, you should consult with your doctor, who can test your blood levels.

If your levels are low, you should always discuss taking over-the-counter (OTC) supplements with a doctor familiar with your medical history.

Are Natural Testosterone Boosters Safe?

Overall, the ingredients in most natural testosterone boosters appear safe and have not had any significant adverse effects in clinical studies. However, certain supplements can interact with medications or cause unwanted side effects.

For example, Korean red ginseng is known to interact with certain medications.[20] 

It’s also important to remember that these products are not approved by the FDA. Many supplements contain high amounts of substances that may have strong effects on your body. This can potentially cause harm or complicate your health.

You should always consult with your healthcare provider before starting any supplement to ensure there are no interactions that may occur.

How To Choose The Best Testosterone Booster?

When buying natural testosterone booster pills, it’s essential to do your homework before purchasing a product. Doing your research first is key to increasing your chances of satisfaction.

Here are a few key factors to consider before purchasing testosterone supplements.

Ingredients

One of the main things you’ll want to consider before purchasing testosterone booster supplements is the ingredients in the product. You’ll want to avoid formulas with additives and choose an all-natural, safe formula to avoid harming your health.

We also recommend choosing a product with research-backed ingredients that have been proven in studies to improve testosterone levels.

Third-Party Lab Certification

To ensure a product’s safety, quality, and purity, consider choosing a product that a third party has tested. This type of testing can give you peace of mind knowing that your supplement is free of potentially harmful or hidden ingredients. It also will help verify what you’re getting is actually what is on the product label.

Brand Reputation

What customers say about a brand is a great way to determine if you should purchase it. Check out real user reviews to see what they say about the product or brand. If most customers are happy, it’s more likely you will be too.

Instead of looking at the reviews on the website, try to navigate through other websites like Trustpilot or Reddit to get honest reviews.

Customer Service

If you have any issues with the product or would like to initiate a refund, it is important to have a helpful support team on standby, ready to assist. Choose a brand with a welcoming and efficient customer service team ready to answer your query and resolve any complaints.

Dosage

For some, it may be difficult to take a product that has to be taken several times per day. If you are looking for convenience, consider choosing a brand that requires only one dose a day.

Final Thought

Living with the side effects of low testosterone levels in the body can be frustrating. Not only can it negatively impact your sexual health, but it may also affect your appearance. 

Many supplements on the market contain ingredients that may help boost testosterone levels. However, all products are not created equal. It’s important to do your research and choose a quality supplement to make your time and money spent worth it.

If you believe your testosterone levels are low, it’s essential to speak with a qualified healthcare provider who can draw blood to find out where your levels are. If your levels are suboptimal, they can also discuss natural supplements or other treatment options with you.

Frequently Asked Questions

What causes low testosterone?

As man ages, testosterone levels naturally decline, which may lead to low testosterone. Some other conditions such as testicular trauma, hormone imbalances, or chemotherapy treatment may also cause low testosterone levels.

What are the symptoms of low testosterone?

Symptoms of low testosterone include decreased energy levels, low sex drive, erectile dysfunction, depression, and decreased muscle mass.

How to naturally boost testosterone?

The best way to boost testosterone naturally is to exercise regularly, maintain a healthy weight, and eat a well-balanced, nutrient-rich diet.

What are the best foods to boost testosterone?

Foods rich in zinc like oysters and red meat may help improve testosterone levels. Additionally, magnesium-rich foods like spinach, kale, and broccoli may also support healthy testosterone levels.

What is the most effective testosterone booster?

At this time, there is minimal evidence to support the use of over-the-counter testosterone boosters. However, the testosterone booster supplements we’ve discussed in this article contain ingredients that may work to enhance testosterone production. More studies should be completed to establish a relationship between certain ingredients or products and testosterone production.

Do testosterone boosters actually work?

The only testosterone boosters proven to work are approved by the FDA and require a visit with your healthcare provider, who will give you a prescription for a pill, gel, or injectable. However, many users report improvements in testosterone levels in the body after taking a high-quality, testosterone-boosting supplement.

What are natural testosterone booster side effects?

Many popular ingredients in testosterone-boosting supplements have generally been well-tolerated in studies with minimal side effects. However, each product’s ingredients may vary slightly. Some ingredients may interact with other medications, so it’s important to speak with your doctor before using testosterone-boosting supplements.
