Frequently asked questions
What is Theanine good for?
Theanine provides amino acids that serve as building blocks for proteins.
When should I take amino acids?
Often best on an empty stomach for optimal absorption.
Can I take this with protein?
Yes, though taking separately may improve absorption.
What are amino acids used for in the body?
Amino acids build proteins, neurotransmitters, hormones, and enzymes. Each has specific functions beyond protein synthesis.
Are amino acid supplements safe?
Generally yes for most people. Those with certain metabolic conditions should consult a practitioner.
Why take individual amino acids vs protein?
Individual amino acids provide targeted therapeutic effects. Protein provides balanced nutrition for general needs.
