Kion Aminos Capsules vs Nutricost EAA Capsules

Buy the Kion Aminos capsules if you want a full clinical dose of all nine EAAs in a capsule and care about a clean label. Buy Nutricost EAA if you want a small, easy two-capsule serving and a large capsule count. Kion delivers about 5 g of EAAs per seven-capsule serving, with 2 g of leucine, and is vegan, non-GMO and free of fillers and dyes. Nutricost delivers 1,200 mg per two-capsule serving and lists magnesium as a mineral. Kion's 4.9 rating from 860 ratings is stronger than Nutricost's 4.6 from 61, but Kion means swallowing seven capsules a day.

  • Choose the Kion Aminos if you want a clinically dosed 5 g EAA serving with 2 g leucine and a clean vegan label.
  • Choose the Nutricost EAA if you want a compact two-capsule serving and a large capsule count.

Questions and answers

Which is better for muscle recovery?
Kion Aminos. Its 5 g serving with 2 g leucine matches the doses used in EAA recovery research. Nutricost's 1,200 mg serving is far smaller, so you would need several servings to match it.
Which is easier to take every day?
Nutricost. Two capsules per serving is far easier than Kion's seven. If you dislike swallowing pills, that gap matters more than the dose difference.
Does Nutricost list how much leucine it has?
No. The label gives only the total 1,200 mg EAA figure and the amino acid list. Kion publishes every amino acid amount, including 2,000 mg of leucine.
Is Kion worth stepping up to?
Yes if you want a full clinical EAA dose and a clean vegan label in one product. Stay with Nutricost if a small serving and a big capsule count matter more to you.
Are both gluten free?
Yes. Both are labeled gluten free. Kion also states vegan, soy-free and non-GMO, and says it uses no binders, fillers, stearates, coatings or dyes.
Which has more servings per container?
Nutricost, with 120 two-capsule servings from 240 capsules. Kion has 30 seven-capsule servings from 210 capsules.

The two-capsule serving is seen as reasonable by some and as too many pills by others.
