Optimizing natural testosterone levels is a key to muscle growth. One of the best ways to do that is through proper supplementation. Of course, 5% Nutrition has several potent testosterone boosters. One of these is 5% Nutrition Core ZMA - the new leader in Core testosterone products!

Ingredient Profile

Zinc - 30 mg

This important mineral plays a primary role in promoting healthy levels of testosterone. It also supports a healthy immune system and plays a role in protein metabolism. 

Magnesium - 450 mg

The mineral magnesium is essential in supporting muscle contraction and nerve transmission. It also supports electrolyte balance, energy metabolism, and plays a role in protein synthesis. Studies have suggested that intense workouts can lead to the loss of magnesium and zinc through sweat. This is the reason it is critical to restore these essential minerals as soon as possible. 

Vitamin B6 - 10.5 mg

One of the B vitamins, B6 has a role in the production of melatonin. Of course, melatonin aids restful sleep. It also supports serotonin production, which helps the body relax. Plus, it supports the production of norepinephrine, a neurotransmitter that plays a major role in mood. 

Boron -  5 mg

This key mineral helps increase the body's conversion of total testosterone into free testosterone. This is huge. After all, free testosterone is the amount that’s available for muscle growth. 

5% Nutrition Core Series - The Next Level Of Core Supplements!

If you look at the Core line of most other supplement companies, you will see that they consist of just a single ingredient. That’s fine if you’re looking for less-than-stellar results. It took 5% Nutrition to take the concept of a “Core” line and supercharge it by adding in 1-2 supporting ingredients. Who else but 5% could come up with an idea like that? This seemingly simple change completely changes these products and pushes them right to the top of the category. So if you’re looking for something more than just another Core product, look no further than 5% Nutrition!
