Frequently asked questions

How do powder and capsule labels compare?

Use the declared L-glutamine amount for the same quantity or serving basis. A scoop, a capsule and a recommended daily portion are different measures; check their stated amounts before comparing.

Does an unflavoured product contain only L-glutamine?

Not necessarily. Unflavoured describes the flavour, not the complete ingredient list. Read the ingredients for capsule materials, processing aids or other components stated on the pack.

Which mixing and use instructions should I follow?

Follow the directions on the exact product, including the portion size, liquid quantity and frequency where stated. Do not copy a scoop measure or daily amount from another product.
