Frequently Asked Questions

What is the difference between EAAs and BCAAs?

BCAAs (Leucine, Isoleucine, Valine) are three of the nine Essential Amino Acids (EAAs). While BCAAs are excellent for muscle energy and recovery, a complete EAA formula provides all the necessary building blocks your body needs for optimal muscle protein synthesis and other vital functions.

Is this product only for serious athletes?

No. While it’s certified safe for elite athletes, Thorne’s Amino Complex is beneficial for anyone who is physically active. It can help reduce soreness from a weekend hike, support muscle tone from regular gym sessions, or provide a clean energy boost for any activity.

Why is the NSF Certified for Sport® seal important?

This certification is the highest standard in sports nutrition. It guarantees that every batch of the product has been tested to be free from banned substances, contaminants, and that it accurately reflects what is on the label. It signifies the ultimate level of trust and purity.
