A Bit About Testosterone

Low testosterone can seriously hamper quality of life—particularly among men over 30. It’s a fact that from the age of 30 testosterone levels in men drop 1% per year. This mean’s that the average man has a testosterone production level in his 50s which is half what it was in his 20s. 

On top of the natural reduction of testosterone with age, there is myriad lifestyle and health factors that can lead to unnaturally low levels of testosterone even in younger men. These include a poor diet, stress, lack of exercise, and a mixture of overt and underlying health issues. 

The consequences of low testosterone range from depression, erectile dysfunction, fatigue, weight gain, irritability, memory loss, cognitive impairment, and muscle atrophy. 

Fortunately, there are many natural supplements that can help restore testosterone levels in both men and women. Unlike anabolic steroids, which are extremely unhealthy (not to mention illegal), natural testosterone boosters are safe to use and lead to few, if any, side effects. The best testosterone boosters are chiefly derived from plants and food stuffs. 

Today, there is a range of high-end testosterone boosting products that have combined the best supplements into highly-effective formulas that boost testosterone naturally and safely. These testosterone boosters support normal processes in the body, essentially fuelling natural testosterone production.

Best Testosterone Booster Ingredients 

When it comes to boosting testosterone levels naturally there are two main considerations: ingredients and doses. The best testosterone supplements are those that are clinically proven to work. But just choosing the right ingredient is not enough, it also needs to be included at an effective dosage that has also been proven.

Many cheap testosterone boosters include the right ingredients in the wrong amounts. The best testosterone boosters feature the right ingredients in effective amounts. Here are our top picks for testosterone supplements:

D-Aspartic Acid 

D-aspartic acid is an amino acid that leads to the production and release of luteinizing hormone [1]. The luteinizing hormone works by stimulating natural testosterone production in the testes, raising testosterone levels rapidly. One study, conducted on a group of 23 men, demonstrated a 42% increase in testosterone levels among 20 out of 23 of the men [2]. Each man was given just over three grams of d-aspartic acid during the experiment (which is slightly less than is included in a daily serving of Prime Male).


Ashwagandha is traditionally used in Ayurvedic medicine to treat stress, but recent studies have found it can also have a powerful impact on testosterone levels, leading to more testosterone, and quickly. A 600mg dose was shown to boost testosterone production by 15% within two months [3]. Another study connected ashwagandha to body fat loss and an increase in athletic performance [4]. In addition, ashwgandha supports the immune system, lowers blood pressure, and reduces inflammation.


As noted above, luteolin is an estrogen blocker rather than a direct testosterone booster. The best testosterone booster supplements will feature both estrogen blockers and testosterone boosters, thus creating an overall more beneficial hormone profile. Luteolin is a flavonoid found in citrus fruits. It effectively limits the production of aromatase, which is needed to produce estrogen [5]. And here's the kicker, in addition to being an estrogen blocker, luteolin is also an indirect testosterone booster because it encourages androgens to synthesise more testosterone.


Ginseng began being used medicinally in ancient China and today is known to provide a whole host of health benefits, from reducing inflammation and boosting cognitive functioning, to curing erectile dysfunction and increasing testosterone production. There are two types of ginseng: the American variety and the Asian variety. Only the Asian varieties of ginseng, such as Korean ginseng, have been proven to be effective testosterone boosters, increasing both free testosterone and total testosterone levels [6]. Its true power, however, is curing male impotence. It has been shown to increase blood flow to the penis by relaxing muscles and preventing blood vessel stress.

Zinc & Magnesium 

Although zinc and magnesium are clearly two separate ingredients, we've lumped them together here because in both cases it is having a deficiency that is the main issue. Low levels of zinc or magnesium can dramatically decrease testosterone levels and taking them in supplement form will rapidly produce testosterone. The best testosterone boosters will have both in ample amounts to ensure deficiencies don't hold you back. Some natural testosterone supplements also have oyster extract, which is a great source of zinc.

Vitamin D

One of the best testosterone-boosting ingredients is vitamin d. Vitamin d supplementation helps with all sorts of ailments. Everything from immune system function, to mineral regulation, to weight loss, to mood regulation is supported by vitamin d. Like with magnesium and zinc, a vitamin d deficiency will lower your natural production of testosterone, but to get the most out of this supplement as a testosterone booster, you need to take it in high quantities. One study, conducted over the course of a year, gave participants a daily dose of 3,332 IU (equivalent to roughly 900mcg) of vitamin D. At the end of the year, researchers found that the vitamin d group had significantly increased levels of free testosterone, bioactive testosterone, and total testosterone, while the placebo group experienced no changes [7]. There are many quality studies confirming vitamin d's testosterone boosting qualities, leading us to conclude that, at high doses, vitamin d is one of the best natural testosterone boosters.

Vitamin K2 

Vitamin k2, also known as menaquinone, has shown to have powerful effects on testosterone production in rats. In a study looking at the testicular tissue of rats-which is surprisingly similar to the testicular tissue of a human-researchers found an increase in testosterone of over 70% in some rats and 56% on average [8].

You want to make sure that the testosterone boosters you use contain vitamin k2 as opposed to vitamin k1. Vitamin k1 is an important vitamin, but it doesn't produce testosterone like vitamin k2 does [9]. In addition to the benefits vitamin k2 provides in its own right, it works together with vitamin d, increasing its testosterone-boosting effects.

Black Pepper

Black pepper, or BioPerine as it is also known, doesn't boost testosterone but it is a bio-enhancer. It increases the bioavailability of other ingredients. In short, black pepper is a formula effectiveness multiplier. It ensures the body is able to effectively absorb all the ingredients and make the best use of them. Testosterone boosters with black pepper (or BioPerine) are going to be more effective, offering more bang for your buck.
