Our analysis — editorial take, not from the label
Trades the Original's 7 g of BCAAs for full nine-amino coverage at a smaller total: a 5 g blend per 8.2 g scoop with 1.5 g leucine, every amino spelled out individually, and the headline 10 g EAA claim resting on taking two scoops.

Cautions
- The 10 g EAA figure on the front of the tub is a two-serving number; one scoop supplies 5 g
- 250 mg of the 5 g blend is L-arginine, which is not an essential amino acid
- Sweetened with sucralose and acesulfame potassium

Product details
Where this label sits
Xtend EAA is one of the amino formulas in the Scoop Sense database. The label uses at least one proprietary blend, so a blend total stands in place of the individual amounts inside it. It runs 40 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of September 2026 — never from the marketing page.
Key ingredients & studied doses
- XTEND EAA Amino Blend · 5 g. Covers all nine essential amino acids, but the per-scoop total sits under the roughly 10 to 15 g used in most free-form EAA research — the label's own two-scoop direction is what reaches 10 g.
- L-Leucine · 1.5 g. Below the roughly 2.5 to 3 g leucine amount commonly used to trigger muscle protein synthesis in studies; two scoops reach 3 g.
- Electrolytes (sodium, potassium) · 150 mg sodium / 120 mg potassium. A light electrolyte addition for sipping during training, far below the amounts in dedicated hydration mixes.
Flavors & sweetener
Four flavors — Mango, Lemon Lime, Blood Orange and Watermelon — sugar-free and sweetened with sucralose plus acesulfame potassium; the 328 g net weight is the Mango tub's, and the others vary a little.
Who it's best for
People who want the full essential amino spectrum around training. Skip it if you want every individual dose disclosed on the label. Derived from the label figures above — not medical advice.
How we log this label
Every entry is built the same way: we read the current supplement facts panel, log each disclosed dose, compare it against the amounts used in published research, flag proprietary blends, and state the cautions plainly. The full methodology explains each step.
This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice. The bars compare what the label states; we do not laboratory-test the product to confirm it.
-
Leucine1.5 g
At or above the studied amount0studied range 0.7 g–3 g4 g
The ISSN position stand puts an acute protein dose at 700–3000 mg of leucine, and about 1–3 g per meal as the amount needed to stimulate protein translation.
Source: Jäger et al., Journal of the International Society of Sports Nutrition 2017 — “Acute protein doses should strive to contain 700–3000 mg of leucine and/or a higher relative leucine content”
-
Total EAAs5 g
At or above the studied amount0studied range 1.5 g–15 g20 g
Stimulation of muscle protein synthesis has been reported from as little as 1.5 g of EAAs, with the maximal useful single dose put at 15–18 g — more in one sitting adds nothing. BCAAs alone supply only three of the nine essential amino acids.
Source: Ferrando et al., Journal of the International Society of Sports Nutrition 2023 — “Reasonable dosage of an EAA supplement does not exceed 15 g, meaning that even as much as three maximal doses per day is in line with normal daily consumption of EAAs…”
-
Sodium150 mg
The studied range is 300–700 mg of sodium per litre of fluid, and this label does not state the volume to mix a serving into — so its concentration, which is what the range measures, cannot be worked out from the panel. Check the mixing instructions on the pack.
Source: Mosler et al., German Journal of Sports Medicine 2020 (DGE position) — “the optimal sports drink should contain 400-1100 mg / l sodium in addition to carbohydrates (4-8%)”
One or more amounts on this label sit inside a proprietary blend, so the individual doses behind the blend total cannot be compared at all.
Common questions about Xtend EAA
Is Xtend EAA an EAA or a BCAA product?
A full-spectrum EAA product: 5 g of essential amino acids per serving, of which 3 g are the three BCAAs. Research on muscle protein synthesis centers on the full nine essential aminos rather than BCAAs alone.
What does the proprietary blend in Xtend EAA hide?
The XTEND EAA Amino Blend lists 5 g as a combined total. A blend total tells you the sum of its ingredients, not the individual doses inside it — which is why blend entries can't be checked against studied amounts.
Do the numbers for Xtend EAA assume one scoop or two?
All figures on this page are per full labeled serving. The 10 g EAA figure on the front of the tub is a two-serving number; one scoop supplies 5 g.
