Men and women both need testosterone to stay healthy (men need more), but unfortunately, average testosterone levels are declining. The culprit is most likely an increase in sedentary lifestyles at a desk, as well as unhealthy diets. This is worrisome, as testosterone plays an important role in all kinds of bodily functions, including weight loss, muscle development, sex drive and bone strength.
If you’ve been noticing any signs of low testosterone (unable to gain muscle, sudden weight gain, low libido, to name a few) we highly recommend speaking to a doctor because any number of medical issues could be in play. But, if you’re averse to seeing a doctor and also confident your symptoms stem from a decline in your body’s natural testosterone production, taking a testosterone supplement could help.
Though the science is thin on over-the-counter supplements that claim to boost testosterone, the anecdotal evidence of their efficacy is stronger. Many guys (of all ages) have started using testosterone supplements because they incorporate safe ingredients, result in minimal side effects — when used as directed — and only require a small pill or shake (no shots).
Most testosterone supplements work by directly increasing testosterone-related hormones or limiting the conversion of testosterone to estrogen. And judging by the skyrocketing popularity and great reviews, it seems these supplements are working, at least for some users. Check out some of the best-reviewed and most popular testosterone supplements below.
1. Genius Test Smart Testosterone Booster for Men
The Genius Test Smart Testosterone Booster for Men sets itself apart by explicitly denying what it will not do (and for what it’s worth, what no testosterone booster or supplement can do). On the flip side, it promises nothing further than optimizing energy levels, mental clarity and male drive, which is to say nothing concrete or objective. But it does have multiple ingredients that appeared to help users, some of whom claimed it improved their energy levels and body health.

2. Roman Testosterone Support Supplements

Roman is one of the best telemedicine companies for men.

Your results will vary, but Roman is an easy brand to start a healthy journey with and one you can trust and take at face value.

3. Prime Labs Men’s Test Booster
BEST-SELLER ON AMAZON
Though nothing exceptional jumps out at us from the Prime Labs Men’s Test Booster to — you know — actually improve testosterone, this supplement is the current best-selling sports nutrition testosterone booster on Amazon, with users praising it for improved energy and libido. We can confirm this supplement does contain horny goat weed, a plant with limited but proven efficacy to improve blood flow to the penis, which can consequently boost libido.

4. BulkSupplements D-Aspartic Acid Powder Supplement
BEST D-ASPARTIC ACID SUPPLEMENT
For a testosterone supplement based around D-aspartic acid, we like the BulkSupplements D-Aspartic Acid Powder Supplement. D-aspartic acid is a natural amino acid that’s directly linked to testosterone production via the production of luteinizing hormone, an essential ingredient to produce testosterone. D-aspartic acid also actually has some legit, if old, research to back it up. Throw about one tablespoon of the powder into a shake each morning before breakfast for best results.

5. Nature’s Bounty Zinc Caplets
BEST ZINC SUPPLEMENT
Zinc is an essential nutrient for the human body involved in hundreds of biological processes, including the formation of semen. While it is not known to directly boost testosterone, it is known to be important to general health and may indirectly improve any lack of energy or libido you’re experiencing. For straight zinc supplements, the Nature’s Bounty Zinc Caplets are the best. They’re chemically pure and highly rated by users.

6. NaturaLife Labs Organic Ashwagandha Powder and Root Extract Supplement
BEST ASHWAGANDHA SUPPLEMENT
Taking a page of Indian alternative medicine, you might consider the NaturaLife Labs Organic Ashwagandha Powder and Root Extract supplement. Proven claims of efficacy in terms of testosterone boosting are scant, but multiple users reported quality of life improvements such as better sleep, less anxiety and general feelings of improved body health. Though that might not be exactly what you’re looking for, if you’re struggling to pin down a specific problem or solution, this could be worth a trial.

7. Pure Encapsulations Tribulus Formula Supplement
BEST TRIBULUS SUPPLEMENT
Tribulus terrestris is a hardy plant thought to help boost testosterone levels. We’re not going to lie: There are no studies or hard evidence to support this and anecdotal evidence is inconclusive at best. Even reviewers were hit or miss on the efficacy of this Pure Encapsulations Tribulus Formula supplement, with some reporting no benefits and others reporting improved testosterone and erectile function. At the same time, it’s hard to judge because this supplement also contains D-aspartic acid, which does support testosterone production. So without much science in either direction, you’ll have to decide for yourself if Tribulus is worth trying out.

8. Brooks Men’s Adrenaline GTS 21
BEST FOR EXERCISE
Finally, the part where we can give you the best advice to actually boost your testosterone: You need to exercise! In life and medicine, there are few, if any, silver bullets. Exercise is one of them for an unbelievable amount of ailments. (Seriously, if you could put the effects of exercise in a pill, people would call it magic.) So if you decide you must try out testosterone supplements, at least pick up a pair of Brooks Men’s Adrenaline GTS 21 running sneakers — SPY’s favorite running shoes — and go for a run. Adding a bit of exercise into your routine — even a daily 10-minute jog — will do wonders for your body health and can only improve your testosterone situation.

9. Slumber Cloud Lightweight Cooling Comforter
BEST SLEEP IMPROVER
For the second-best piece of advice to improve your testosterone, you need to sleep better. Like exercise, sleep is practically a miracle cure for a number of health issues. Of course, one night of good sleep won’t do it; you’ll need better sleep in general for the best results. That’s why we recommend upgrading your sleeping conditions, starting with the excellent Slumber Cloud Lightweight Cooling Comforter, SPY’s top pick for cooling comforters.
This blanket, designed with NASA technology and supported by sleep research, will help keep you feeling cool in bed so you can get a full night’s rest for once.
