TestoFuel Review

What ingredients are in TestoFuel?

D-aspartic acid (D-AA) – 2300 mg

This is non-essential amino acid That is related to testosterone production and conversion of substances into testosterone. Usually, the daily dose for adult males is 2,000-3,000 mg. Particularly, for infertile men, D-AA can increase testosterone levels. Resistance training athletes can use D aspartic acid as a temporary booster.

D-AA works in the brain to trigger a release of hormones. Studies indicate that D-AA is concentrated in glands accountable for sexual functioning. D-AA stimulates the release of Luteinizing Hormone, this results in the testes producing testosterone. As a result, this boosts testosterone that results in the bodies estrogen levels dropping.

A study concluded: “We demonstrated that D-aspartic acid, which occurs as a physiological compound in the mammalian pituitary and testis, plays a role in the regulation of the release and synthesis of LH and testosterone.”

Vitamin D3 – 5000 IU

One of the more familiar vitamins, vitamin D is taken in by exposure to sunlight (by a reaction with ultraviolet light) . Generally, D3 can also be obtained by consuming various foods; oily fish, dairy products and cereals. It’s preferable to gain vitamin D from the above sources. A study published in 2010 reported: “We aim to evaluate whether vitamin D supplementation influences testosterone levels in men. Results suggest vitamin D supplementation can increase testosterone levels.”

Oyster extract – 100 mg

Oysters are the quintessential aphrodisiac (though champagne is a close contender). Ask Casanova, who devoured oysters by the truckload. In 2005, The Daily Telegraph journalist A Lusher reported, oysters are rich in amino acids to increase levels of sex hormones. One of the amino acids present in oysters was the aforementioned D-aspartic acid. An article titled 6 Foods That Boost Testosterone, oysters came out top. Oysters are well-known to contain unusually high levels of zinc (a natural testosterone booster in its own right). Indeed, it is generally agreed that oysters contain the most zinc than that of any other types of foods. 100g of cooked oysters contains about 79 mg of zinc (over 500% of the daily value). By comparison, zinc-rich lean beef contains just 12mg of zinc per 100g.

Ginseng – 100 mg

Panax Ginseng is a plant native to East Asia and North America. Historically, it has been used in Chinese medicine to treat a variety of sexual/ libido problems. Ginseng is known to improve blood flow and nitric oxide, this both improves recovery and aids libido. Studies indicate ginseng may reduce cholesterol, help erectile dysfunction, and improve libido. Low levels of both adrenocorticotropic hormone (ACTH) and adrenaline suggest low levels of testosterone. As a result, ginseng can help raise amounts of both of these hormones.

Fenugreek – 100 mg

A herb native to warmer climates of southern Europe and Asia, Fenugreek is widely used for its libido-enhancing powers. Brisbane’s University of Queensland concluded that Fenugreek extract “demonstrated a significant positive effect on libido and may assist to maintain normal healthy testosterone levels.” Another point worth noting is that Fenugreek contains saponins. These are naturally-occurring chemical compounds which may: promote the release of LH; block other enzymes that convert testosterone into other forms; and increase levels of testosterone’s precursor molecules. As a final point, there is some evidence that powdered Fenugreek seeds may help with the control of blood glucose.

Magnesium – 200 mg

An essential factor in any sportsman’s diet, magnesium assists with the metabolism of carbohydrates and proteins. Crucially, for a testosterone booster like TestoFuel, a study reported “supplementation with magnesium can increase your free and total testosterone values in sedentary and in athletes. Hormone improvements are higher in people who exercise than in inactive individuals.” This means, users who exercise regularly when taking magnesium supplements generally boost their testosterone levels higher compared to those who take supplements without exercising. Also, Magnesium is said to improve exercise performance of users who workout.

Vitamin B6 – 5 mg

A key vitamin in the “B” group, vitamin B6 reduces estrogen production, thereby increasing testosterone levels. An Austrian study revealed that vitamin B6 plays an important part in testosterone production: individuals with adequate vitamin B6 levels possess significantly higher testosterone levels than those with lower levels of the vitamin.

Vitamin K2 – 18 mcg

Not heard of it, eh? Don’t worry not many people have. Vitamin K is present (mostly) in green leafy vegetables and cheese, and most research has been conducted using the humble rat. Scientists concluded that there is a correlation between low vitamin K levels and low testosterone levels. It’s not the most conclusive statement. However, it’s generally agreed you will need to adequate vitamin intake for healthy hormone levels. To conclude, medical professionals suggest that vitamin K plays a direct role on testosterone synthesis, which can be affected by low vitamin K levels. Generally, vitamin k2 is a vitamin K type you won’t consume as much of. Vitamin K2 is a factor for ranking TF above TestoGen.

Zinc – 10 mg

An essential mineral (and metal) for various reasons, but can Zinc boost your testosterone? Medical professionals agree a zinc deficiency is prevalent throughout the world (including the USA). In addition to this, in men with severe/ moderate zinc deficiency is associated with hypogonadism (lower function of the gonads). Research concludes zinc can play an important role in modulating serum testosterone levels in normal men. Undoubtedly, zinc is a key ingredient for testosterone supplements.
