#6 of 7 · Lowest Price per Gram✓ Label verified · Supplement Facts read Oct 11, 2026Real retailer photo, cut out. Label unedited.
Consider it if price per gram is the only thing that matters. Ten grams of amino acids for forty-eight cents is hard to beat, and the ingredient list is as short as it gets.

Marketing Claims Vs. Reality
10 g of essential amino acids per serving.
The panel prints a 10 g blend of the nine essential amino acids. It gives no split, so the amount of each one cannot be checked.
Third-party tested.
The listing states it, and NSF's Certified for Sport database lists one lot of the 1 kg bag. The 500 g bag we link is not on that NSF record.
What Our Test Actually Found
The one number that is missing
Leucine is what triggers muscle protein synthesis, and an EAA label is where you look for it. This panel names leucine first in the blend, which by labelling convention means it is the largest component, and stops there.
Certified, for a different bag
The NSF listing is real, and it is specific: one lot, 1 kg package. If the certification matters to you, buy that size and match the lot number on nsfsport.com.

- $0.48 per 10 g, the cheapest here
- 10 g of amino acids per serving
- One other ingredient
- 50 servings a bag
- Proprietary blend: no amount for leucine or any other amino acid
- NSF listing covers one lot of the 1 kg bag only
- Unflavored and bitter
- Teaspoon measure
- You want the lowest cost per gram
- You want an unflavored powder with one excipient
- You are fine not knowing the leucine amount
- You want to know how much leucine you take
- You are drug-tested: only one lot of the 1 kg bag is NSF listed
- You dislike measuring 4 teaspoons of bitter powder
Ten grams of amino acids for forty-eight cents is hard to beat, and the ingredient list is as short as it gets. Because the blend is proprietary, the leucine dose is unknown, which is the number an EAA product is bought for. Nutricost costs a little more and prints every amount.
BulkSupplements sells 500 g of essential amino acids for $23.97, which makes a 10 g serving cost $0.48 (Amazon US, Oct 11, 2026). The panel reads 'Essential Amino Acids 10 g' and then 'Proprietary Blend', followed by nine names: leucine, isoleucine, valine, lysine HCl, threonine, phenylalanine, methionine, histidine HCl and tryptophan. It prints one total and no amount for any single amino acid, so you cannot tell how much leucine a serving holds. The only other ingredient is sunflower lecithin. NSF's Certified for Sport database lists the unflavored EAA powder for one lot of the 1 kg bag (listing 1796669); the 500 g bag we link is not on that record.
Cheap and plain, with the key number left out
If you only want grams of amino acids for the least money, this is it. We rank it sixth because an EAA product that does not print its leucine amount asks you to trust the blend. Nutricost prints every amount for $0.75 per 10 g.
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.
