Frequently Asked Questions
What is the best amino acids supplement?
Based on our analysis of 775 amino acids products, GABA 250 mg ranks #1 with a SupplementScore of 78/100. Scores are based on label quality - dosage transparency, formulation cleanliness, and ingredient disclosure.
How are amino acids supplements scored?
Every product is scored algorithmically using data from the NIH Dietary Supplement Label Database. The SupplementScore evaluates dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts).
Does a higher score mean the supplement works better?
No. The score reflects label quality, how transparent and clean the product label is, not clinical efficacy, bioavailability, or safety. A higher score means better label practices, not guaranteed results.
