Prime Male Reviews: Effective T-booster or not worth the money?

Could Prime Male Vitality be your key to improved health? We'll break down all of the pros and cons

Last Updated: Jan 4, 2023
Prime Male Reviews

If age is just a number, why does each year bring lower energy, more challenging workouts, and less dynamism in the bedroom? If this all sounds too familiar, low testosterone could be to blame.

Fertility in males is steadily decreasing worldwide for reasons yet unknown to modern researchers. And a troubling 2020 clinical study revealed that as many as 40% of men have low testosterone levels by age 45.

These findings may explain the rising popularity of testosterone boosters for men to increase their energy, make gains at the gym, and get that old mojo back. Prime Male Vitality is one such testosterone-boosting supplement that aims to help.

In this review, we’ll look at how it works and help you decide if it’s the right choice for you.

What is Prime Male?

Prime Male is a supplement company focused on improving men’s health through optimal testosterone levels and better sexual performance. The company offers two products, but in this review, we explicitly focused on the product that aims to improve testosterone levels: Prime Male Vitality.

Vitality is a capsule supplement, and its formula to regain healthy levels of testosterone relies on 12 natural ingredients:

  • D-Aspartic Acid
  • Black Pepper
  • Boron
  • Korean Red Ginseng
  • Luteolin
  • Magnesium
  • Ashwagandha
  • Nettle Root Extract
  • Vitamins B6, D3, K2
  • Zinc

Prime Male Vitality aims to help men with low testosterone levels heighten their mood and libido, build muscle, and improve general health.

Who should consider Prime Male Vitality?

Any male over 30 years old who suffers from symptoms of low testosterone should consider giving Prime Male Vitality a try. The addition of other essential vitamins, minerals, and beneficial herbs could be one valuable part of maintaining your overall health.

Some signs of low testosterone include:

  • Depressed mood
  • Fatigue
  • Loss of mental sharpness
  • Low sex drive
  • Erectile dysfunction
  • Failure to make gains in the gym

Who won't find Prime Male Vitality useful?

Suffering from any of the above symptoms isn’t a guarantee that low testosterone is to blame. If you’re failing to see results you want in the gym or bedroom from anything other than low testosterone, you may want to give Prime Male Vitality a pass.

To help you determine whether you need a product like Prime Male Vitality, we recommend taking a testosterone test. There are several reliable at-home tests available from companies that offer Innerbody readers exclusive discounts. You can read about all of them in our guide to the best at-home testeosterone test.

How Prime Male works

Prime Male doesn’t replace or contain any testosterone. Instead, it employs ingredients that promote testosterone production naturally.

Each bottle contains 30 servings of four daily capsules. You’ll take one capsule with each meal and one with a snack.

You should know that not every ingredient has been proven to boost testosterone specifically. In some cases, the element indirectly enhances an aspect of a male’s hormonal health. And in others, the ingredient helps in an unrelated area like improving metabolic function or reducing inflammation.

A closer look at each ingredient below will help you understand how it works and decide if Prime Male is right for you.

D-Aspartic Acid Calcium/DAAC (1,600 mg)

Prime Male claims that DAAC increased testosterone (T) by up to 42% in 12 days. In one particular study, DAAC did accomplish this in a small sample of men. But according to a clinical review of 23 animal studies and four human trials, there were limitations to the research. Other studies in the same review revealed unpredictable results. There are clear links between DAAC and sperm count/motility. But it remains inconclusive that DAAC reliably boosts T levels in humans.

Black Pepper (10 mg)

Black pepper enhances the bioavailability of various nutrients and drugs thanks to a compound called piperine (contained in most peppers). That means you’ll absorb more of the nutrients you take in as you digest them. Piperine is safe for humans and brings potential benefits along with it, like reducing inflammation and insulin resistance. But, this animal study found piperine encourages Leydig cell development (increases T production) while reducing spermatogenesis (sperm production) in rats.

Boron (5 mg)

A clinical review confirms Prime Male’s claim that boron increases T levels in men. About 98% of testosterone in men is bound to sex hormone-binding globulins (SHBG). These bound sex hormones are less beneficial than free ones since they are, in essence, inert. Boron regulates SHBG levels to increase free testosterone. This could aid aging men with lowered T counts and higher concentrations of SHBG (a natural effect of aging).

Korean Red Ginseng 4:1 Extract (120 mg)

Korean Red Ginseng is a powerful herb for men’s sexual health. A comprehensive study showed men experienced significantly higher quality erections after taking 1,000 mg three times per day for 12 weeks. Total and free T counts increased along with luteinizing hormone (responsible for sex hormone production). And sperm counts and motility improved while displaying a more protective membrane than a control group.

Luteolin (60 mg)

Luteolin is a flavonoid found in celery, broccoli, artichokes, green peppers, navel oranges, olive oil, and common cooking herbs. Use as a testosterone-booster was never its original purpose. Experts first researched this compound for its potential effects in estrogen-based cancers. But, a clinical study revealed luteolin inhibits estrogen production, which may help males with high estrogen counts. And another trial proved luteolin increased testosterone synthesis.

Magnesium (100 mg)

Researchers have studied magnesium intensively for its role in muscular function and metabolic processes. Over time, experts discovered that magnesium plays a role in 300 enzymatic reactions in our body. One clinical study found that magnesium deficiency is common in older people. It went on to describe a link between higher magnesium levels, athletic performance, and more free testosterone. Another study found similar increases in free testosterone among both sedentary and athletic people given magnesium (10 mg/per kg of body weight per day).

Ashwagandha 4:1 Root Extract (300 mg)

Since ancient times, mystics and medicine men have used ashwagandha to cure all sorts of ailments and even expel demons. But does ashwagandha have any science to back up its benefits? Well, a 2015 study tested men in a double-blind trial to measure how the herb affected results in resistance training. The ashwagandha group saw larger gains in muscle mass and strength. They also showed a significant increase in testosterone (nearly 5x as much) as the control group. While more research is needed, there seem to be clear links between testosterone, physical performance, and ashwagandha use.

Nettle Root 10:1 Extract (160 mg)

The addition of nettle root extract is a curious choice. Open studies show that nettle root may have potential benefits for people with BPH (prostate gland enlargement). And it’s loaded with vitamins, minerals, and every essential amino acid. This clinical study also proves that compounds in the root bind to SBGH, perhaps creating more free testosterone in turn. But as of this writing, there are no studies to confirm nettle root as an effective booster of testosterone as a result.

Vitamin B6 (7.5 mg)

According to this animal study, low levels of B6 might play a factor in deficiency and less effective action of testosterone. Prime Male helps avoid this possibility by including a surplus of B6. This important vitamin also helps elevate your mood, improve circulation, and bolster your immune system.

Vitamin D3 (4,000 IU)

Vitamin D3 is the “sunshine molecule” we absorb from time outdoors. But it’s easy to be deficient here when the demands of modern life get in the way. If you have low vitamin D levels, Prime Male can promote testosterone production and raise total T levels. This clinical study shows you may experience significant effects from this addition to Prime Male’s formula.

Vitamin K2/Menaquinone-7 (45 mcg)

Vitamin K2 is an essential compound in several organs, including the testes. Researchers have yet to discover the exact role K2 plays and its mechanism of action therein. One animal study saw significant increases in testosterone production in rats, but these results haven’t been confirmed in humans yet.

Zinc (30 mcg)

A clinical study showed a strong correlation between zinc deficiency and low T levels among 40 men aged 20-80. Older men given zinc supplements for six months showed significant improvements in serum testosterone. This addition to Prime Male helps you maintain healthy zinc levels and avoid lowered testosterone from a deficiency.

Is Prime Male Vitality safe?

Each ingredient in Prime Male is all-natural and should be safe for most men. You speak to your doctor and ask if Prime Male will interact with any prescription medications.

Be sure not to take any other vitamin D supplements with Prime Male. Four thousand IUs per day is the maximum recommended amount. And if you’re taking magnesium supplements, keep your daily intake at 350 mg or less.


One bottle of Prime Male Vitality will last you a month and costs $69.

A 2-month supply and costs $138.

A 4-month supply includes a fifth bottle of Prime Male and costs $207.

Orders of $130 and up qualify for a free bottle of the company’s Hunter Burn thermogenic fat burner.

HSA, FSA, and Health Insurance

Prime Male Vitality is not applicable for HSA, FSA, or health insurance.

Is Prime Male Vitality a good value?

The decision here ultimately lies with how much you value the ingredients’ other benefits besides boosting your testosterone level. A bottle of Prime Male is about $10 more than average among similar products. And compared to other supplements, not every ingredient is clinically proven to increase your testosterone.

But, you might consider Prime Male as a way to safely encourage healthy T levels while also enjoying the lateral benefits that ingredients like nettle root and ashwagandha can offer.
