Buying Guide: Amino Acids
📋 Table of Contents
1What's the difference between BCAAs and EAAs?
BCAAs (branched-chain amino acids) contain only 3 amino acids and are good for muscle recovery during workouts, while EAAs (essential amino acids) include all 9 essential amino acids your body can't make itself. EAAs are more complete but BCAAs are often cheaper and better if you're just training.
2How do I know if an amino acid supplement is high quality?
Look for third-party tested products (Informed Choice or NSF certified) and check the label for the specific amino acid amounts in grams. Avoid products that list "proprietary blends" without showing individual ingredient amounts, as you won't know what you're actually getting.
3Should I buy powder or tablets/capsules?
Powder is more cost-effective and lets you adjust doses, but tablets are convenient if you travel or dislike mixing drinks. Powder also mixes better into your pre-workout or post-workout shakes compared to swallowing multiple capsules.
4What serving size should I choose?
For daily users, a 250-500g container lasts 1-2 months depending on whether you take it once or twice daily. If you're new to amino acids, start with a smaller size to test tolerance and flavors before committing to bulk purchases.
5Is it worth paying more for flavored amino acids?
Flavored versions cost slightly more but make a real difference if you're drinking it daily—unflavored can taste metallic and bitter. If taste matters to you, flavored is worth the extra cost; if you're mixing it into a smoothie anyway, save money with unflavored.
