A whey or plant protein serving carries several times the essential amino acids of a scoop of pure aminos, so the powder wins only on convenience and on days when solid food or a thick shake is unappealing.</div></details><details><summary>What about branched-chain amino acid tubs?</summary><div class="a">Three of the nine is a strange thing to buy. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9571679/" target="_blank" rel="noopener">A systematic review of oral branched-chain supplementation in athletes</a> found the soreness signal was the most consistent finding, with performance and body composition effects negligible. A full essential profile is the more defensible purchase.</div></details><details><summary>Will this build muscle on its own?</summary><div class="a">No, and no honest reading of the literature says it will. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10561576/" target="_blank" rel="noopener">The essential amino acid position stand held in the NIH library</a> describes amino acids as raw material for muscle protein synthesis, and raw material without a training stimulus is just an expensive drink.</div></details><details><summary>Is there anyone who should not take it?</summary><div class="a">Anyone with kidney disease or on a protein restricted diet should ask their clinician first, and so should anyone pregnant or nursing, since the manufacturer's own label advises against use. Unexplained muscle loss, poor appetite or unintended weight change deserve a medical assessment rather than a supplement, and <a href="https://ods.od.nih.gov/factsheets/ExerciseAndAthleticPerformance-Consumer/" target="_blank" rel="noopener">the consumer fact sheet on exercise supplements</a> is a fair place to start reading.</div></details></div><div class="src-list"><h3>Sources</h3><ul><li><a href="https://ods.od.nih.gov/factsheets/ExerciseAndAthleticPerformance-HealthProfessional/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Dietary Supplements for Exercise and Athletic Performance, Health Professional Fact Sheet</a></li><li><a href="https://ods.od.nih.gov/factsheets/ExerciseAndAthleticPerformance-Consumer/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Dietary Supplements for Exercise and Athletic Performance, Consumer Fact Sheet</a></li><li><a href="https://www.nia.nih.gov/news/how-can-strength-training-build-healthier-bodies-we-age" target="_blank" rel="noopener">National Institute on Aging: How Can Strength Training Build Healthier Bodies as We Age</a></li><li><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4394186/" target="_blank" rel="noopener">NIH National Library of Medicine: Protein Intake and Muscle Function in Older Adults</a></li><li><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11369567/" target="_blank" rel="noopener">NIH National Library of Medicine: Protein Supplementation Combined With Resistance Exercise in Older Adults With Sarcopenia</a></li><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12674588/" target="_blank" rel="noopener">NIH National Library of Medicine: Oral Pure Branched-Chain Amino Acid Supplementation, Exercise Performance and Body Composition</a></li><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9571679/" target="_blank" rel="noopener">NIH National Library of Medicine: Oral Branched-Chain Amino Acids Supplementation in Athletes, a Systematic Review</a></li><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10561576/" target="_blank" rel="noopener">NIH National Library of Medicine: Essential Amino Acid Supplementation on Skeletal Muscle and Performance</a></li><li><a href="https://ods.od.nih.gov/factsheets/WYNTK-Consumer/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Dietary Supplements, What You Need to Know</a></li><li><a href="https://www.nccih.nih.gov/health/using-dietary-supplements-wisely" target="_blank" rel="noopener">NCCIH: Using Dietary Supplements Wisely</a></li></ul></div><div class="ac-sig"><div class="rule"></div><p class="toyour">To your health,</p><svg width="320" height="72" viewBox="0 0 320 72" role="img" aria-label="Ageless Coach.
