What Is Testosterone?
Testosterone is a steroid hormone produced in the testes in males and in the ovaries and adrenal glands in females.
In males, testosterone plays an important role in sexual development, drive, and function. Testosterone is also important in the development of muscle mass and strength, as well as in red blood cell production, blood flow, and bone density. Furthermore, testosterone can influence blood pressure, with healthy levels generally associated with better cardiovascular health.
Testosterone also plays a significant role in a man’s cognitive abilities, fat distribution, moods, and overall sense of well-being [1]
How Does Aging Affect Testosterone Levels?
Unlike the sudden drop in hormone levels women experience during menopause, men’s testosterone levels decrease at a slower rate, typically 1-2% per year after age 40 [2].
A decline in testosterone levels is considered a normal part of aging in men and is medically known as late-onset hypogonadism..
While many men will maintain testosterone levels in the normal range, just on the lower side, others will experience a more rapid decline and will start to show symptoms. In such cases, a healthcare provider may discuss options like hormone replacement therapy to help manage these symptoms and improve quality of life.
Common Signs of Low Testosterone Levels in Men
Some of the various physical and psychological symptoms that can accompany declining testosterone levels in men can include:
Decreased Sex Drive
Common symptoms of low testosterone levels in men can include a lowering of sexual desire, erectile dysfunction, fewer morning erections, and decreased ejaculation volume [3].
Low Energy
Feeling unusually tired after a small amount of activity or even after having a suitable amount of rest is another common symptom of low T.
Muscle Weakness
Because testosterone plays a big role in muscle strength and mass, lowering levels of this hormone can cause a noticeable decrease in both [4].
Mood Swings
If you find yourself unusually irritable, depressed, or having difficulty concentrating and wondering why you’re suddenly becoming a grumpy old man, it could be low testosterone [5].

What To Look for in the Best Testosterone Boosters
Choosing the best testosterone booster can be tricky with so many options out there. To find one that’s truly effective and safe, focus on these key factors.
Quality Ingredients
- Fenugreek: Subjects taking an extract of fenugreek in a study showed a significant improvement in both free and total testosterone levels in 8 weeks [6].
- Ashwagandha: In a 2022 study of 57 men taking 600 mg of ashwagandha extract per day for 8 weeks, there was an increase of nearly 15% in their testosterone levels [7].
- Zinc: This mineral has been shown to maintain optimum free testosterone levels, promoting erectile function and male sexual activity [8].
- D-Aspartic Acid: A study found that in healthy men aged 27-37 taking D-aspartic acid supplements for 12 days raised T-levels an average of 42% [9].
- Tribulus Terrestris: A systematic review shows a correlation between Tribulus terrestris and the treatment of erectile dysfunction and sexual problems in adult males [10].
Scientific Evidence
Check to see that the supplement you’re considering provides citations for studies showing the efficacy of the ingredients they have used to formulate their testosterone boosting supplement. Also, check to see that all the ingredients listed have been third-party tested.
Reputation & Reviews
The length of time a company has been around, as well as their customer reviews, are both good indicators that the T-boosting product they’re offering has been consistently benefiting people.
Dosage
Beware of high dosages when it comes to testosterone boosters. That’s because certain ingredients may be effective at a particular serving size, yet could be harmful at higher doses. If in doubt, check with your doctor beforehand.
Price
Some testosterone boosters can be fairly expensive, although many manufacturers offer subscription services that lower the cost if you make larger orders.

Ways To Support the Supplementation of Testosterone Boosters
We’ve shown you some of the best testosterone boosters on the market, yet they’re not magic pills. So, how can you get the most out of these boosters and increase testosterone effectively?
Regular Exercise
Engaging in regular vigorous exercise like high-intensity interval training (HIIT) and weightlifting will help to both stimulate your body to produce testosterone and build muscle mass.
Maintain a Healthy Weight
Since obesity is linked to low testosterone levels, maintaining a healthy weight is crucial to helping stimulate testosterone production.
Eat a Balanced Diet
A diet rich in whole foods, lean protein, antioxidants, and healthy fats will help stimulate healthy testosterone production, while processed foods, saturated fats, and alcohol will inhibit it.
Get Proper Rest
Research showed that prolonged lack of sleep can reduce a healthy young man’s overall testosterone levels [20].
Manage Stress
A 2016 study reported that low levels of serum testosterone occur during both physical and psychological stress, directly linking stress to hormonal balance. This connection is often mediated by elevated cortisol levels, as chronic stress triggers an increase in this hormone, which can, in turn, suppress testosterone production [21].
FAQs
Here are some questions posed by readers regarding the best testosterone booster on the market today.
What Is the Most Effective Supplement To Boost Testosterone?
TestoPrime is our top pick; it includes well-researched ingredients like D-aspartic acid (DAA), which plays an important role in testosterone production [9].
How To Check Testosterone Levels?
To check testosterone levels requires a blood test, usually in the morning when testosterone levels are peaking.
What Are Signs of Low Testosterone in Men?
Things like low sex drive, erectile dysfunction, loss of muscle mass, fatigue, and mood changes like irritability and depression are often indicators of low testosterone levels in men.
Can Low Testosterone Cause Anger?
Yes, diminishing testosterone levels can contribute to anger stemming from increased irritability and frustration [22]. It is usually more pronounced in those who are prone to feelings of annoyance and short-temperedness.
Which Vitamins Are Best for Testosterone?
Prioritize vitamins A, C, and E. Vitamin D also has testosterone-boosting effects. These vitamins, particularly the antioxidants among them, help protect the cells involved in hormone production.
Best Testosterone Booster: Conclusion
Age sneaks up on us all, and declining testosterone levels can be a frustrating and depressing reminder of that fact for menopausal men. Testosterone shots by prescription are not only expensive over the long term, but can also have some serious side effects in some instances.
This article focused on over-the-counter all-natural testosterone boosters, from the best sports nutrition testosterone boosters to the best testosterone boosters for men over 50. TestoPrime tops our list, but the best one for you will depend on your particular needs.
Before trying any of our suggestions, it would be a good idea to consult with your doctor first to determine if the supplement you’re considering is right for you.
Good luck.
