Testosterone boosters are everywhere. They’re all over the supplement market with a lot of claims, but not a lot of studies. So, what are the best testosterone booster supplements?
In this article, we examine the top testosterone boosters for a man that help the most with production of testosterone: what works – and why. These are nutrients that can help balance your hormone levels that are backed by clinical studies to prove their efficacy as testosterone supplements.
How do Testosterone Boosters help Testosterone Levels?
Natural testosterone boosters help testosterone levels by supplying your body with the natural nutrients it needs to encourage more of the male hormone.

Best Testosterone Booster 2021 (Bodybuilding and Muscle Mass)
Looking to build muscle mass, boost energy levels, and take your lifting career to the next level? Don’t worry – we compiled a list of the best testosterone booster supplements that:
- Boost Muscle Mass
- Increase Endurance
- Speed Up Recovery
- Improve Physique
- And more
Below are the top options that work the best for bodybuilding and muscle mass. They’re back by clinical studies and are the best natural options to give you the biggest return from all your hard work in the gym.
Here’s our top picks:
#2. D-Aspartic Acid in Testosterone Boosters
TL;DR: DAA has been seen in multiple studies to raise testosterone. One study shows it to raise test by 42% over 12 days. Another shows it boosting T levels by an average of 30 – 60% over 90 days. It rocks.
D-Aspartic Acid is an amino acid which is ideal for natural testosterone boosting and muscle mass. It works well because it can help promote your body’s levels of the Luteinizing Hormone (LH).
LH is your body’s precursor to both growth hormone and testosterone. The more of this that you have in your system, the more support your testosterone levels have to rise.
So, to get this amino acid in a testosterone supplement is always a good sign that you’re in for an effective ride.
But just how effective is D-Aspartic Acid compared to other testosterone boosters? Is it the best to boost testosterone?
In one study, men aged between 27 and 37 took D-Aspartic Acid for a period of 12 days. At the end of the study, 20 out of the 23 men that were supplementing DAA had an average increase of 42% in overall testosterone.
Three days later, without using any D-Aspartic Acid, their testosterone was still 22% higher than it had been at the start of the study.
In a similar study, men aged between 27 and 43 took D-Aspartic Acid over a period of 90 days. At the end of the 90 days, there was an average growth of 30 – 60% in overall testosterone.
D-Aspartic Acid is one of the more potent testosterone boosters and a great option for those who are looking to maximize their T levels and improve muscle mass for bodybuilding. One of the better testosterone boosters.
#3. Zinc (Best Mineral for Testosterone Production)
TL;DR: Studies indicate low Zinc levels appear to go hand-in-hand with low testosterone. Not only that, supplementing Zinc can help boost testosterone that has been lowered by intensive training and other factors.
Zinc is one of the most useful testosterone boosters for helping your testosterone levels with bodybuilding and muscle mass.
One of the main advantages that Zinc has, like DAA, is that this mineral can help to raise your overall levels of LH – the Luteinizing Hormone. As we’ve mentioned, fueling your LH can help with increased production and release of your growth hormone and testosterone.
The most notable study is from 2006, where a group of wrestlers were experiencing temporary low testosterone levels from training to exhaustion. When supplementing Zinc it seemed to reverse this effect and restore their T back up to their optimum levels – so they could keep training hard without the downsides.
Another study saw that supplementing Zinc can help to raise serum testosterone levels, in those who had experienced a drop in T from dialysis.
Other studies have indicated a connection to low zinc levels and low T levels. By helping to keep you Zinc intake at an optimum level, you may be able to maintain steady and healthy T and better muscle mass.
It’s a great mineral for free T and one of the main testosterone boosters to help T levels in a man. Another one of the top-tier testosterone boosters.
#4. Vitamin D3 + Vitamin K1 and K2 (Best Vitamins for Testosterone Production)
TL;DR: Numerous studies show that long-term supplementation of Vitamin D3 can help raise your levels of testosterone. Vitamin D is technically a hormone and closely linked to boosting testosterone levels – and experts believe up to 1 billion people are deficient in it!
Vitamin D is an essential vitamin to your body – and it’s also technically a hormone. It’s a potent, natural resource that has been linked to promoting your testosterone level. Especially with Vitamin K2 and K1.
Why do we need to supplement it for bodybuilding and muscle mass?
Because your body naturally absorbs it through your skin via the sun’s rays – and considering that we spend most of our time indoors, that’s not a whole lot of Vitamin D.
Experts actually believe that up to 1 billion people are deficient in Vitamin D. Not only that, studies have also found that there is a link between deficiencies in Vitamin D3 and low testosterone.
In one study, participants were made to spend more time outdoors in the summer sun. In doing so, there was a large spike noticed in their overall testosterone.
A yearlong study, involving participants supplementing Vitamin D supplements daily noticed a 20% increase in testosterone levels on average.
As it is technically a hormone – and one that most of us are deficient in – supplementing vitamin D3 can be huge for promoting your overall testosterone.
It’s always good to supplement Vitamin D3 with Vitamin K2 and K1. Vitamin K2 and K1 can help guide the added calcium to your bones, for a healthier skeleton and joints, as well helping to increase testosterone levels.
Best Testosterone Booster for Males over 40 (Top Ingredients)
As you start to get older, your testosterone levels begin to drop. This typically begins after 30, with your testosterone levels declining around 1% every year.
At first, it’s not that noticeable – but sooner or later the effects start to show. Couple that with the lifestyle changes you face at that age – running a family, more responsibility and generally stress, stress, stress! It’s a cocktail of disaster for your T levels.
However, there are natural ingredients out there which can help with testosterone production, as well as managing your levels of stress. Combined this can give you a testosterone boosting supplement which can not only help your T levels – but can also help your mindset as well. Helping to promote better hormonal balance and more effective lifestyle management.
#5. Ashwagandha (as a Testosterone Booster)
TL;DR: Ashwagandha is arguably one of the most potent herbs when it comes to raising testosterone levels. KSM-66 Ashwagandha is the best and can help raise testosterone, muscles mass and even lower stress.
There are numerous ways that this herb can help improve your levels of T. It can help both directly and indirectly. Personally, we see it as one of the best testosterone boosters.
Indirectly, Ashwagandha can help lower cortisol, your body’s stress hormone. When your cortisol levels are higher, your testosterone levels drop. This is how your body manages the hormones. Ashwagandha has been seen in clinical studies to help reduce levels of the stress hormone, and by extension increase testosterone.
Lowering stress is ideal for the over 40s as this is typically a harder point in your life with children, work and more factors that create low testosterone levels.
In another study, Ashwagandha was seen to promote muscle mass and even reduce body fat by 3.5% compared to the placebo group.
The best form of Ashwagandha is definitely KSM-66. There’s an endless list of clinical studies supporting the KSM-66 strain. It’s seen to help stress, low testosterone levels, endurance, strength, sex drive, weight management, memory, anti-aging, sleep and more.
It’s one of the finest natural testosterone boosting supplements.
#6. Magnesium (for Free T Levels)
TL;DR: You should be looking to get a good amount of Magnesium in your testosterone booster. It’s effective for protecting your free testosterone and maintaining your overall T levels.
Magnesium is one of the better minerals out there for men over 40 for testosterone. It’s effective for helping raise your levels of free testosterone.
Free testosterone is the amount of T that is freely circulating throughout your body. The threat to this type of testosterone is Sex Hormone Binding Globulin (SHBG). SHBG binds to the free testosterone in your system, and strips it of its anabolic potency. The result is that it reduces your overall levels of free testosterone.
Supplementing Magnesium can help to minimize this problem. Studies show that taking Magnesium can help to reduce the impact of SHBG. Magnesium does this by inhibiting the SHBG, which helps stop it from binding to your free flowing testosterone.
#7. Mucuna Pruriens (Leans out Chest Muscle)
TL;DR: Mucuna Pruriens can help raise testosterone, lower stress, fight man boobs and even raise dopamine. What more could you want?
Mucuna Pruriens are a great testosterone booster for males over 40. The main active ingredient that matters most in Mucuna Pruriens is L-DOPA.
L-DOPA can raise your brain’s level of dopamine which can offer a combination of good effects including reducing levels of the stress hormone cortisol, erections, sex drive and generally making you feel better.
What it can also do is increase your levels of GnRH – that’s gonadotropic-releasing hormone. This can help to raise your body’s levels of the Luteinzing Hormone. As we’ve mentioned this is your body’s precursor to both growth hormone, and testosterone.
Another benefit of L-DOPA in Mucuna Pruriens is that it can help reduce your overall levels of prolactin in your body. Prolactin is the hormone in your body which is linked to causing soft breast tissue – or man boobs – which is more of a risk as you get older.
By getting a good supply of L-DOPA, you can help reduce your levels of that hormone, and help create a leaner and meaner chest. It can also help in areas such as stress management and sex drive.
Best Testosterone Booster for Men over 50 (Best Ingredients)
Lower testosterone is an issue in older men. It’s natural – but that doesn’t mean you have to settle for it. There are plenty of natural options out there which can help to fight the process and allow you to maintain (and in some cases raise) as much testosterone as possible at over 50.
However, testosterone isn’t the only problem. Another factor from being older men is a rise in estrogen – the female hormone. This can unbalance your hormones and create more issues for your overall health and improve sex drive.
Below, we have compiled a list of what we believe to be the best testosterone boosters for men over 50. These can help if your testosterone levels are low, or even if you are struggling from a rise in estrogen.
#8. Boron (Top Mineral for Fighting Estrogen)
TL;DR: Boron is great for both raising testosterone, and lowering estrogen. This is ideal as those are big factors that need support as you get older.
Boron makes our list of the top testosterone boosters for men over 50 because it has been clinically proven to do 2 things: boost testosterone, and lower estrogen.
A full review of Boron in 2015 in the IMCJ covered a lot of the mineral’s overall effects, with the main takeaways being that it can help increase free testosterone by nearly 25%. It can also almost have the amount of estradiol (estrogen) in your system, and even allow more free testosterone to bond with proteins in your blood which can help as you age.
With all that considered, this makes it a great choice as a testosterone booster for men over 50. It can tackle many of the age-related factors that affect T as you get older. Including allowing for more protein binding and reducing growing levels of estrogen.
Boron has even been seen to help in these areas with subjects who are suffering from low testosterone. It’s an effective, natural mineral for T levels.
#9. Luteolin (Top Nutrient for Fighting Estrogen)
TL;DR: Luteolin can help lower estrogen – which becomes a much bigger problem as you get older.
The final testosterone booster that we’ll be covering in our list is Luteolin. It is an antioxidant found in citrus fruits like lemons and oranges.
Luteolin is technically not a testosterone booster – but it is a great natural aromatase inhibitor.
The aromatase enzyme is an enzyme in your blood which converts your testosterone into estrogen. As you get older, this enzyme becomes more active, converting more T into estrogen. This is definitely not what you want for hormone optimization.
Studies have shown that supplementing luteolin can potentially inhibit estrogen biosynthesis – which could in turn reduce your overall levels of the female hormone.
As you get older and your estrogen levels rise, and your T levels decline – it’s smart to get all the help you can get. Luteolin has some promising studies behind it and a great tool to help deter a rise in estrogen.

Testosterone Boosting Foods / Not Supplements
Testosterone boosters aren’t everything. Eating right and exercising goes a long way too. Below, we’ve compiled a list of some of the best testosterone boosting foods out there that you should add to your diet to maximize your overall progress.
Here’s a shortlist of the foods that could help you the most.
Tuna as a Testosterone Booster
Tuna contains a rich source of Vitamin D. Vitamin D, as you’ll know by now, is technically a hormone which has close links to raising testosterone levels.
Due to the mercury content, moderation is key with a food like this. Two to three servings a week should be enough for you to get a healthy supply of this vitamin from your food.
Other fish options that contain good amounts of this vitamin would be salmon or sardines. There’s plenty of options.
Milk as a Testosterone Booster
Milk is another good source of Vitamin D. Mostly touted for it’s ability to help bones and muscles through its high calcium and protein content, many people forget that it also contains a good amount of Vitamin D.
Again, with a nice amount of D in here, milk can help support a rise in your testosterone levels.
Pro-tip: Opting for a lower fat milk like skimmed or semi-skimmed may be a wise idea to avoid saturated fat content.
Egg Yolks as a Testosterone Booster
Again, another rich source of Vitamin D. Eggs can help raise testosterone levels by offering a good amount of this natural vitamin.
Not only that, eggs are also an effective source of healthy cholesterol. This can help support the leydig cells in your body to promote overall testosterone.
An egg a day is a good way to get the health benefits from this food, without overdoing it.
Fortified Cereals as a Testosterone Booster
Cereals that have been fortified with Vitamin D can be ideal for helping low testosterone. Getting fortified cereals into your diet can help increase your overall vitamin D and increase testosterone levels.
These types of cereals also pack vitamins and minerals that offer general health benefits to keep you going.
Oysters for Low Test
Unlike most of the other food we’ve mentioned, oysters are good for testosterone due to their level of Zinc.
Zinc is a great example of testosterone boosting supplements, as it can increase your levels of the luteinizing hormone (LH), which is your body’s precursor to both growth hormone and testosterone.
Beef is a red meat that you shouldn’t over-consume. However, in moderate amounts it can be fine for your health – and even beneficial to your testosterone.
Beef contains a good amount of Zinc and Vitamin D, which can both contribute as testosterone boosting supplements.
Finally, a nice plant-based testosterone booster in our list of T boosting foods. Beans, lentils, chickpeas and more all contain a good amount of Zinc.
It’s a nice natural testosterone booster and an easy one to have with numerous meals to improve your low testosterone levels and give yourself a good amount of protein.
