There are many different types of testosterone boosting nutrients on the market, which all are capable of different functions.
These are the main 3 functions you can expect depending on what T-Booster you decide to get:
These are the core ingredients to testosterone production.
They supply your body with the nutrients it needs to carry out all the steps necessary to increasing your overall testosterone.
Free Testosterone Promoters
These nutrients serve a secondary function, which is nearly as important as producing testosterone – promoting free testosterone.
Free testosterone are the T-levels that are circulating in your blood stream that you have immediate access to for both muscle gains and overall health – however you don’t have access to all of it.
On average you can only use around 40% of it at a time.
This is down to a protein called Sex Hormone Binding Globulin (SHBG) which binds to the other 60% – this strips the T-cells of their anabolic qualities and makes them useless when it comes to actual muscle gains.
These Free Testosterone Promoting nutrients inhibit the SHBG and lower the amount of testosterone they bind to in the blood stream.
They essentially allow you to maintain the T that you make.
Aromatase Inhibitors (Estrogen Suppressants)
These are found more commonly in testosterone boosters for the older man aged 35 and up.
As you get older, not only does your testosterone decrease, but your estrogen levels rise.
This is all down to the Aromatase Enzyme which converts testosterone into the female hormone.
Aromatase Inhibitors suppress the enzyme making their overall production of estrogen far slower and less effective.
This gives your testosterone all the room it needs to continue to grow.
The Top 10 Natural Testosterone Boosting Nutrients
According to our research – these are the best natural T-Boosting ingredients out there.
1. Vitamin D3
Don’t let the name fool you. Vitamin D3 is actually a hormone and can have a serious impact on your T-levels.
D3 is without a doubt, the most potent testosterone booster out there.
But an estimated 1 billion people are deficient in it! 
Absorbed mainly by our skin from the sun’s rays, it’s hard for you to get enough of it. Especially when you factor in people spending most of their time indoors, both at work and at home.
Studies have shown men supplementing over 3000 IUs of Vitamin D3 a day have both increased serum testosterone and free testosterone.
2. D-Aspartic Acid
The top amino acid for testosterone boosting.
DAA is one of the key components needed for reactions in the brain to provoke hormone releases – such as testosterone.
This nutrient is used to create the Lutienizing Hormone (LH) which is essential to both the production of testosterone and growth hormone. It’s a vital nutrient to have in your stack.
Studies have supplementing 2.66g of D-Aspartic Acid on a daily basis can increase serum testosterone by up to 30-60% over a period of 90 days.
This is arguably the best mineral in the testosterone boosting process.
Much like DAA, Zinc is needed for key reactions in the brain that creates LH – which is the precursor to growth hormone and testosterone.
You can get zinc from things like red meats and leafy greens – however, you’d do your Test levels a favor by supplementing it – or by eating Oysters.
Studies have shown Zinc supplementation to support athletes during long training seasons, keeping their testosterone levels elevated despite the constant stresses their body is under – on the flipside, athlete’s supplementing the placebo saw huge drops in their T-levels.
4. Oyster Extract
Also known as the ‘muscle multivitamin’, Oyster Extract contains many good ingredients that support the testosterone boosting process.
Containing 10x as much Zinc than you’d find in red meat, Oyster Extract is perfect for anyone looking to boost T.
Oyster Extract has also been seen to contain numerous amino acids, vitamins and other minerals which all support general health and well-being.
Studies have shown supplementing Oyster Extract can be just as effective for raising testosterone as zinc – the study was carried out on Zinc deficient subjects with the Oyster Extract performing the same functions.
Zinc may be the best mineral for producing testosterone, but magnesium is the best for promoting free testosterone.
Known for it’s ability to inhibit the Sex Hormone Binding Globulin protein (SHBG).
Magnesium helps maintain and support testosterone circulating in the bloodstream.
Studies have shown that daily supplementation of Magnesium greatly improves free testosterone – in both sedentary individuals and athletes.
This is one of the more interesting free testosterone promoters.
This is mainly because it’s hard to get enough of it throughout the day.
Found in foods like prunes, chickpeas and pears – these aren’t usually everyone’s go-to foods.
But they should be, as boron kicks ass at boosting Free Testosterone.
One study in particular has seen boron do incredible things. Subjects experienced a 29% increase in testosterone and a 39% decrease in estrogen.
A nutrient used in traditional medicine for libido enhancement – however there’s a lot that this nutrient can also do for our T-levels.
One of the main things Fenugreek does well is regulate blood sugar.
High blood sugar is one of the biggest causes of low testosterone as insulin directly affects T-levels.
Lower blood sugar makes this less of a problem.
Studies have shown that regular supplementation Fenugreek boosts sex drive and increases testosterone levels.
8. Asian Red Panax Ginseng
This type of Ginseng helps with two things:
Testosterone and erections.
It’s a powerful libido enhancer.
In terms of how it raises T, this ginseng, like Fenugreek, lowers blood glucose levels and diminishes the amount of SHBG in the blood stream.
Over the course of 12 weeks, men with erectile dysfunction supplemented Red Ginseng on a daily basis. The result was a dramatic increase in their erection strength and penetration success.
One of the best natural aromatase inhibitors you can come across.
Luteolin is a flavonoid that was compared against over 1,400 other natural ingredients.
It was seen to be the most effective when it comes to reducing estrogen levels.
Definitely something for the older man looking to boost testosteorne levels.
Studies have shown that luteolin is by far one of the most potent natural aromatase inhibitors you can come across.
10. Stinging Nettle
Another aromatase inhibitor to lower estrogen production.
But it also increases free testosterone.
One of the best things about stinging nettle is it’s ability to reduce Sex Hormone Binding Globulin (SHBG).
This increases the overall amount of free testosterone.
Stinging Nettle has been reported to have a dramatic affect when it comes to reducing Sex Hormone Binding Globulin.
The Best Place to Find These Nutrients
These are all the top nutrients that you can find to boost testosterone without turning to drugs or steroids.
But where is the best place to find nutrients like this?
It’s highly unlikely that you can fit all of these nutrients efficiently into your diet and still manage to get generous doses of all of them.
To do that you need a natural testosterone booster.
Natural T-Boosters provide your body with all the nutrients it needs to dramatically boost testosterone levels and increase muscle gains – but not all T-Boosters are made equal.
