Active Ingredients

Leucine

Leucine is one of the three amino acids that are known as BCAAs.

Research has shown that leucine can significantly reduce catabolism, as well as improve muscle development (1).

Essential Amino Acids

Essential amino acids (EAAs) are amino acids that the human body cannot create on its own.

This requires them to be obtained from a range of food sources, each of which contain varying amounts of each amino acid. Alternatively, supplementation allows EAAs to be taken in a fixed ratio, optimised for muscle-building.

Studies show that EAAs significantly increase muscle protein synthesis in humans (2).

Who Takes It?

Athletes wanting to prevent muscle breakdown during workouts, or improve their growth and recovery will enjoy using Amino IV.

How to Take

Mix 2 scoops (12.5g) with 300-500mL water, and consume during your workout.

Side Effects

There are no significant side effects associated with the ingredients in Amino IV.

Pros

Large dose of Leucine to maximise muscle protein synthesis
Dissolves and absorbs better than regular leucine
Multiple flavours available.

Cons

Perhaps not enough of the other 2 BCAAs included.

Conclusion

Amino IV is a fantastic amino acid product which contains a great dose of Leucine and other essential amino acids.

One serving contains about double the leucine that is found in most other amino acid supplements, and the form used means it may mix and absorb better, too.

The only downside may be a slight shortage of the other two BCAAs isoleucine and valine, which are generally used up by the body in proportion to leucine.
