Recovery & Amino Acids
BCAA, EAA, glutamine, and collagen supplements for people who want to support muscle repair, reduce soreness, and recover faster between training sessions.
What to Look For
- BCAAs vs. EAAs: BCAAs include three essential amino acids; EAA formulas contain all nine and are more complete for recovery. If you are not meeting protein targets through food, EAAs are the better choice.
- Leucine content: Leucine is the primary amino acid that triggers muscle protein synthesis. Look for at least 2–3g of leucine per serving in BCAA and EAA products.
- Collagen vs. complete protein: Collagen supports connective tissue (tendons, ligaments, cartilage) but is not a complete protein for muscle. Use it alongside a complete protein source, not as a standalone recovery supplement.
Frequently Asked Questions
What is the difference between BCAAs and EAAs?
BCAAs are three of the nine essential amino acids: leucine, isoleucine, and valine. EAAs include all nine essential amino acids the body cannot make on its own. If you already eat enough total protein from whole foods or protein powder, BCAAs add limited benefit. EAAs are more useful if your total protein intake is low or you train fasted.
Do I need amino acid supplements if I eat enough protein?
Probably not for muscle building. If you are hitting 0.7–1g protein per pound of bodyweight from food and protein powder, separate amino acid supplements add little on top. They are most useful for people training fasted, following very low-calorie diets, or looking for an intra-workout recovery signal.
When should I take recovery supplements?
Intra-workout or immediately post-workout are the most common windows. The post-workout period (within 1–2 hours) is when muscle protein synthesis is elevated and muscles are most receptive to amino acid uptake. That said, total daily protein intake matters more than precise timing for most people.
