Ingredients Label

Active Ingredients

Zinc

Zinc is an essential mineral, which athletes are often deficient in, due to its loss via sweat.

Zinc has been found to be important for testosterone levels and physical performance (1).

The recommended daily intake is around 15mg.

Ashwaghanda

Ashwagandha is an adaptogenic plant.

Research shows that it can boost both athletic performance and testosterone levels in untrained people, but more research needs to be done in athletes (2).

An effective dose is 300-500mg.

Eurycoma Longifolia

Eurycoma Longifolia is a plant with aphrodisiac effects.

In men who have abnormally low testosterone levels, or who are stressed, supplementation may improve testosterone levels (3).

The effective dose is 200-300mg of a 100:1 extract.

Shilajit

Shilajit is a substance formed from the slow decomposition of plants.

It’s been shown by limited research to increase testosterone levels in infertile men (4).

As with many of the other ingredients, more research is required in healthy subjects.

DIM

Diindolylmethane (DIM) is a naturally-occurring compound in vegetables such as broccoli.

It’s been shown to have oestrogen-blocking effects, which can result in greater levels of free testosterone (5).

Who Takes It?

Male athletes who are of older age, or have otherwise abnormally low testosterone levels will benefit most from taking Ferodrox.

How to Take

Take 2 capsules daily with food, preferably in the morning.

Side Effects

May alter general mood, and increase libido.

Pros

Improves testosterone through multiple mechanisms
May improve physical performance
Improves energy levels.

Cons

May only work for men with abnormally low testosterone levels
Research in healthy males is limited for most ingredients.

Conclusion

Ferodrox is a well-rounded testosterone booster which taps into a variety of mechanisms for improving testosterone levels.

It contains a combination of herbs, minerals, and more, all of which have a positive influence on testosterone.

Most of these ingredients, however, have only been shown to work in men who have lower testosterone levels than normal.

This supplement will most likely only be worth the money if you’re an older male, or have abnormally low testosterone levels.
