TestoFuel ingredients

What TestoFuel does better than anyone else is use the right ingredients, with the right doses, to optimize your T levels.

Keep reading our TestoFuel review to discover what’s inside and how the ingredients work.

1. Vitamin D3

Known as the sunshine vitamin, D3 is technically a hormone… and an important one too when it comes to stimulating androgen production.

The ‘sixth steroid hormone’ is one of the most extensively researched nutrients out there.

It’s been shown to improve everything from bone, muscle and vascular health, to mood, brain power and immune system efficiency, vitamin D3 really is one of the best supplements out there.

When it comes to testosterone, vitamin D3 has been found to have a direct influence. In one study, a daily dose of 3,332 IU resulted in over a 25% increase in androgen levels [1].

And another study found that older men with low vitamin D levels were much more likely to have lower free testosterone levels – as well as a significantly higher risk of bone problems [2].

2. D-Aspartic acid

This amino acid is used to synthesise new protein cells.

As a neurotransmitter, D-AA as it’s commonly known, has been shown to help boost muscle mass and power output, speed up fat loss – and most of all, increase testosterone levels.

It does this by triggering the release of the androgen precursor called luteinizing hormone. This hormone carries messages from the brain to the testes, essentially working like an alarm clock to wake up testosterone production.

The research is beyond conclusive.

For example, one study reported that in as little as 2 weeks, D-AA ramped up anabolic hormone levels by nearly 50% – and by a massive 60% in 12 weeks [3].

3. Oyster extract

What’s the first thing that comes to mind when you think about aphrodisiac foods? 

That’s right – oysters. For many years this food has been considered to be the absolute best libido-boosting tonic around.

The problem is though that not only are they hard to get hold of, oysters don’t always taste that great either. They are a pretty acquired taste – and for some, just not nice at all.

But that’s where oyster extract comes in. It’s the best natural source of zinc you’ll find – and as such, have been found to effectively treat low mood, brain health, obesity and hormone levels.

When it comes to optimizing androgens, zinc-rich supplements have been shown to elevate T levels even during exhaustive exercise – in both elite level cyclists [4] and football players too [5].

4. Fenugreek

So far, we’ve covered the ingredients that directly increase testosterone levels by stimulating production.

Fenugreek though, attacks your hormones from a different angle. This gives you a double-barrelled assault on your hormone levels.

That’s because this sweet and aromatic Mediterranean herb acts like a defensive wall against SHBG – a type of protein that swallows up testosterone and makes it unusable.

When 30 regular gym-goers were given 500 mg of fenugreek each day for 8 weeks, a number of significant benefits occurred [6].

• A sharp increase in total and free testosterone
• Muscle mass increased and fat decrased
• Bench press and leg press strength improved

5. Ginseng

This mildly spicy, bitter herb has long been thought of as a libido enhancer as well as potent aphrodisiac. But it’s much more than that.

Ginseng boosts cognitive ability and brain power [7], meaning you can channel your energy into more productive gym workouts.

The result? More muscle, more strength.

Ginseng also plays a part in regulating your insulin sensitivity, meaning you’ll find it easier to curb your food craving and shred fat whilst on a weight cut.

But the real benefit here is the effect of ginseng on testosterone levels.

That’s because much like fenugreek, this Asian herb has the power to kick your luteinizing hormone into action – remember, this hormone is the one that slaps your testes into pumping out more testosterone.

And as an added extra, ginseng  has also been shown to have a direct action on androgen production too – ramping up both testosterone and its derivative hormone DHT in as little as a few weeks [8].

6. Zinc

We’ve already talked about the power of zinc when we introduced you to oyster extract. But it’s such a potent mineral that TestoFuel have added another 10 mg just to make sure your low androgen levels have no where to hide.

Men with low zinc levels are pretty much guaranteed to have low serum testosterone levels [9].

It really is that important!

This essential mineral stimulates testosterone directly by putting the brakes on aromatization – the process by which high levels of testosterone get converted to the female hormone estrogen [10].

So while other commanding TestoFuel nutrients work hard to up your androgen levels, zinc works even harder to make sure these sky high levels remain elevated.

7. Magnesium

Another essential mineral – magnesium – is responsible for managing hundreds of biological reactions in the body.

Magnesium is the chemical version of the traffic officer – guiding your enzymes to the right places in order to optimize health and performance.

From ensuring good sleep quality, to regulating your metabolic rate; magnesium is one of the most important minerals you’s want to find in a high-quality testosterone-boosting supplement like TestoFuel.

When it comes to boosting hormone levels, this chemical element is a fast-acting, dynamic and forceful mineral that has been shown to elevate testosterone in as little as 4 weeks [11].

8. Vitamin K2

There’s the brash and powerful potency of D-AA and there’s the strong and reliable sturdiness of vitamin D3 in TestoFuel.

Together, they form a full on assault on your low hormone levels.

But there’s also the silent confidence of nutrients such as vitamin K2 – a fat-soluble compound known as menaquinone. 

That’s because K2 supports vitamin D3 in its testosterone-boosting role, giving it a helping hand in ramping up your androgen levels.

Vitamin K2 has even been seen to lead to 70% increases in testosterone over less than 6 weeks too, when supplemented on its own [12].

While D3 might steal the limelight, K2 is definitely a formidable supporting player.

9. Vitamin B6

Last but not least, there’s B6 – a water-soluble vitamin known for its ability to regulate energy by controlling and supporting your metabolism.

Much like zinc, B6 hacks away at aromatization, helping you to keep hold of your newly acquired sky-high testosterone levels – by as much as 30% in some studies [13].

It also boost other androgens that support testosterone as well.

It’s a great all-rounded and helps to keep this fantastic supplement grounded and formidable.
