We read all 88 pages of the world's leading sports nutrition body's official position on essential amino acids — so you don't have to. Here's what matters, with verbatim quotes, original visualisations, and one interactive calculator.
Verbatim from the position statement abstract. We've added plain-English context underneath each.
"Essential amino acids (EAAs) are required components of the human diet, and their availability stimulates muscle protein synthesis (MPS)."
EAAs are the only protein components your body cannot make itself. They are the trigger and the building blocks of every gram of new muscle.
Ferrando et al., 2023 · Conclusion 1"Free-form EAA ingestion induces a rapid (within minutes) and pronounced rise in peripheral EAA concentrations, in turn driving an increased rate of MPS."
Free-form EAAs bypass digestion. Plasma levels spike in 15 minutes — vs 60–90 minutes for whey protein.
Ferrando et al., 2023 · Conclusion 2"The MPS response to EAA ingestion is dose-dependent in a non-linear fashion."
Twice the EAAs does not equal twice the MPS. There is a threshold and a ceiling.
Ferrando et al., 2023 · Conclusion 3"MPS is stimulated by oral consumption of as little as 1.5–3.0 g of EAAs and reaches a maximum at approximately 15–18 g."
A single Bare scoop (5g) sits at ~80% of maximum MPS — the optimal point on the dose-response curve for most adults.
Ferrando et al., 2023 · Conclusion 4"Increasing the availability of non-essential amino acids (NEAAs) beyond what is required to support normal physiology does not result in any further increase in MPS over the EAAs alone."
The non-essential amino acids in whey protein are metabolic ballast for MPS purposes — calories without performance return.
Ferrando et al., 2023 · Conclusion 5"Free-form EAA supplementation provides a uniquely effective method of stimulating MPS that is not dependent on the digestion or absorption of intact protein."
EAAs work even when whole-protein digestion is impaired — useful intra-training, fasted, or for older adults with reduced gastric function.
Ferrando et al., 2023 · Conclusion 6"Repeated EAA-induced stimulation of MPS does not diminish the anabolic response to subsequent meals."
There is no 'muscle full' effect within a day. Multiple EAA doses + meals each trigger fresh MPS — the more spikes, the more total muscle built.
Ferrando et al., 2023 · Conclusion 7"An increased intake of leucine, achieved either by greater protein intake or supplemental EAAs containing higher proportions of leucine, may overcome the anabolic resistance associated with aging."
After 50, the leucine threshold rises. Bare's leucine-enriched formula (40% leucine vs ~10% in whey) directly addresses this.
Ferrando et al., 2023 · Conclusion 8"EAA supplementation enhances the recovery of skeletal muscle function following exercise-induced muscle damage."
Faster recovery, less soreness, more frequent productive sessions — the practical outcome of consistent EAA dosing.
Ferrando et al., 2023 · Conclusion 9"Supplemental EAAs may be a viable strategy to maintain muscle mass during periods of caloric restriction."
Cutting? You need MORE EAAs, not less. A 5g scoop adds zero meaningful calories but preserves the muscle a deficit would otherwise sacrifice.
Ferrando et al., 2023 · Conclusion 10"MPS is stimulated by oral consumption of as little as 1.5–3.0 g of EAAs and reaches a maximum at approximately 15–18 g." — Ferrando et al., 2023, Conclusion 4
The threshold scales roughly with lean body mass — heavier athletes need slightly more EAAs to trigger maximal MPS. One 5g Bare scoop comfortably crosses threshold for most adults under 100kg.
"Free-form EAA ingestion induces a rapid (within minutes) and pronounced rise in peripheral EAA concentrations… in turn driving an increased rate of MPS." — Ferrando et al., 2023, Conclusion 2
"Increasing the availability of non-essential amino acids… does not result in any further increase in MPS over the EAAs alone." — Ferrando et al., 2023, Conclusion 5
"Repeated EAA-induced stimulation of MPS does not diminish the anabolic response to subsequent meals." — Ferrando et al., 2023, Conclusion 7
No diminishing returns. Each EAA dose triggers a fresh MPS spike that whole-food meals build on top of — not against.
"An increased intake of leucine, achieved either by greater protein intake or supplemental EAAs containing higher proportions of leucine, may overcome the anabolic resistance associated with aging." — Ferrando et al., 2023, Conclusion 8
Leucine threshold required to overcome anabolic resistance, by age cohort. A single Bare scoop crosses the under-50 threshold; older athletes can stack 1.5–2 scoops.
"Supplemental EAAs may be a viable strategy to maintain muscle mass during periods of caloric restriction." — Ferrando et al., 2023, Conclusion 10
"Essential amino acids (EAAs) are required components of the human diet, and their availability stimulates muscle protein synthesis (MPS).
