Which testosterone booster is the #1?

Are you looking for the best test booster available on the market? Maybe you have you already tried some testosterone level boosting supplements, but the results didn’t satisfy you? Some testosterone boosters are supported by clinical studies on humans, some have collected positive reviews from satisfied users, but ultimately the end results depend also on your body as the results may vary from person to person. Let’s have a look at the natural testosterone boosting supplements and let’s find out which one is the best test booster.

D-Aspartic Acid

D-Aspartic acid (DAA) is a d-form of the non essential amino acid aspartic acid. Aspartic acid has been discovered in 1827 by the French pharmacist Plisson, however the testosterone related properties of the DAA has been confirmed in clinical research on humans only in 2009. The l-aspartic acid is a building block of proteins and thus muscles, the d-aspartic acid is produced from the l-form and stored in some specific tissues (testes, pituitary gland, and hypothalamus), and is used by the body to trigger the production of luteinizing hormone (LH) and gonadotropin-releasing hormone (GnRH) which in turn increase the testosterone production and release. In the above mentioned Italian study (link) 3 grams of the d-aspartic acid was taken daily by 23 men aged between 27 and 37. Their blood levels of the testosterone have been elevated by 42% and of the luteinizing hormone – by 33%. It is worth mentioning that this stunning results have been observed on healthy males with normal test levels prior to the experiment. For some bodybuilders d-aspartic acid is the best test booster as it rises the testosterone levels without the unpleasant side effects, which usually accompany direct testosterone or steroids supplementation. If you ask me – this is the best test booster you can buy now. No known side effects, stunning results and scientific proof of effectiveness.


ZMA stands for zinc monomethionine aspartate and magnesium aspartate. Zinc and magnesium combined with the vitamin B6 has been outlined as a testosterone rising supplement by Victor Conte. A study conducted in 1998 (link) confirmed that ZMA works, however other studies didn’t find it effective. Is it the best test booster? Some ZMA reviews claim it is a very good testosterone booster, but the body of research is split. You can stack ZMA with other testosterone raising supplements to create your own best test booster.


Tribulus or Bulgarian tribulus is a supplement made from tribulus terrestris, a vine native to the Old World. Tribulus terrestris was known in the antiquity, it found uses in Ayurveda and in the traditional Chinese medicine. Tribulus has been re-discovered for the modern science and modern bodybuilding in the 1970s, a Bulgarian study found it to raise blood levels of testosterone. Further clinical research didn’t confirm these results, so it is probably not the best test booster. However there are many scientific studies confirming its aphrodisiac effects, tribulus probably stimulates androgen receptors. If you are looking for the best test booster to improve your sex life, you can take tribulus. Be careful – in some countries (e.g. Australia) tribulus is banned and thus illegal to buy. Tribulus might influence your drug test results.

Cod liver oil

Fermented cod liver oil mixed up with high vitamin butter oil, taken twice a day is the best test booster according to Tim Ferriss. In his best selling book, 4 Hour Body, Tim recommended this supplement along with Brazil nuts and almonds in testosterone raising protocol. Tim claims to have repeated these promising results in experiments on other volunteers than himself. Cod liver oil has been known in Europe for centuries as a natural supplement strengthening the body’s immune system. It contains omega-3 fatty acids, essential for the health of the brain and the nervous system. If you strictly follow the recommendations of Tim Ferriss you can boost your testosterone levels with cod liver oil.

Vitamin D

Who would expect vitamin D to be the best test booster? Clinical research (link) found that this commonly taken vitamin also boosts blood testosterone levels. Vitamin D supplements are recommended anyway, so do yourself a favour and make sure you don’t miss vitamin D in your diet and / or your supplements.


Calcium cannot be missing on the list of the test boosters. Being an important macro mineral (a dietary mineral required in large quantities) calcium can be derived from dairy, leafy vegetables or taken as a supplement. Clinical research found that calcium acts as a natural test booster (link). However another recent study (link) found that calcium taken as a supplement also rises the risk of heart attack, when it gets into the bloodstream once a day in a big dash. You need your dose of calcium, but better stick to dairy which seems to be the safe bet.


Fenugreek is an extract made from seeds of the plant Trigonella foenum-graecum L. growing in the Mediterraneans, Southern Europe and in Western Asia. Beneficial effects of fenugreek supplementation have been already known to Ayurveda and to the Traditional Chinese Medicine. Fenugreek helps in a number of medical conditions, including improving libido in both men and women. The effectiveness of fenugreek in boosting testosterone is disputable, as it is in the case of tribulus.

The search for the best test booster is not easy, the research results are split, and new evidence comes every year. What should you do to raise your testosterone? Probably the most effective method is to create your own best test booster by stacking a number of supplements. Just make sure you know exactly what do you take and don’t overdose any of the supplements.
