Marketing Claims Vs. Reality
10 g EAAs.
True for two scoops. One serving on the panel is 8.2 g of powder with 4,750 mg of essential amino acids.
Zero sugar.
The panel prints 0 g total sugars; sweetness comes from sucralose and acesulfame potassium.
Muscle recovery and muscle growth.
EAAs stimulate muscle protein synthesis (Ferrando 2023); a 5.6 g BCAA drink raised it by 22% over placebo after training (Jackman 2017). The effect on muscle gain depends on total protein intake.
What Our Test Actually Found
Read the front as two scoops
The headline number on the tub is the two-serving column. Plan on two scoops if you want the dose the label advertises; the 40-scoop tub then lasts 20 days.
Flavor is the feature
Unflavored amino acids are bitter. Xtend covers that with flavors and two artificial sweeteners, which is the reason to buy it and the reason it scores low on formula.

- Every amount printed for one and two scoops
- Electrolytes included
- $1.18 per 10 g of EAAs
- Zero sugar
- 4.75 g of EAAs per scoop; two scoops needed
- Sucralose and acesulfame potassium
- Artificial flavors
- No testing statement
- You will only drink aminos that taste good
- You want electrolytes in the same drink
- You are happy to take two scoops
- You avoid sucralose, acesulfame potassium or artificial flavors
- You want a full dose in one scoop
- You need a certified product
Take two scoops and you get 9.5 g of EAAs with 3 g of leucine for $1.12. One scoop alone is under 6 g and under 2 g of leucine. The label is fully open, the electrolytes are a plus for training, and the sweetener system is artificial. No testing statement appears on the label or listing.
Xtend EAA is the tub to pick if taste decides whether you take your aminos. The panel is printed for one and for two servings. One 8.2 g scoop gives a 5 g amino blend: 1.5 g leucine, 750 mg each of isoleucine, valine and threonine, 650 mg lysine HCl, 200 mg phenylalanine, 100 mg tryptophan, 25 mg each of histidine and methionine, plus 250 mg arginine. That is 4,750 mg of essential amino acids per scoop. The '10 g EAAs' on the front refers to two scoops, and the label says to take two servings a day for best results. Each scoop adds 150 mg sodium and 120 mg potassium. It is sweetened with sucralose and acesulfame potassium and uses natural and artificial flavors. On Oct 11, 2026 it cost $22.39 for 40 scoops on Amazon US.
A good-tasting EAA that needs two scoops
Xtend EAA is honest on the panel and pleasant in the glass. Take two scoops for 9.5 g of EAAs and 3 g of leucine. If you avoid artificial sweeteners or want a certified product, look at Momentous; if you want the most amino acids per dollar, NAKED.
If This Doesn’t Fit — Try These
01NAKED EAAs
If you want essential amino acids in a dose that matches the research, this is the tub: 9.25 g with 2.4 g of leucine, all nine amounts printed, nothing added but sunflower lecithin.
02Nutricost EAA Powder
For sixty cents a scoop you get 8 g of EAAs, plenty of leucine and a label that states third-party testing.
03Momentous Vital Aminos
Momentous earns its place with one thing none of the cheaper tubs has: NSF Certified for Sport for every lot, confirmed at the certifier.

PMID 37800468 — International Society of Sports Nutrition Position Stand: Effects of essential amino acid supplementation on exercise and performance. The ISSN position stand concludes that free-form EAAs raise blood EAA levels quickly and stimulate muscle protein synthesis, that the response starts at 1.5 to 3.0 g at rest and plateaus at about 15 to 18 g, that non-essential amino acids are not needed for it, and that aging calls for a larger share of leucine.
