Why would a carnivore athlete use an EAA powder at all?

Most carnivore athletes do not need EAA powder every day. If you already eat enough meat, eggs, and total protein, food does most of the work. Yet EAA powders can help in four common spots: fasted early training, travel days, low appetite phases, and cutting blocks where you want amino acids with fewer calories than a full meal. The ISSN says daily protein near 1.4 to 2.0 g/kg works for most active people, and each feeding should bring a good leucine dose plus the rest of the EAAs. [ISSN protein stand]

What counts as “zero-additive” for this article?

I used a hard screen. A true pass needed all of these: unflavored, no sweeteners, no acids for taste, no gums, no colors, no helper agents like lecithin, and no extra actives beyond the amino acids. That screen is tighter than most brand claims. “No artificial sweeteners” is not the same as “zero-additive.” “Unflavored” is not the same as “plain amino acids only.” This matters because many labels that look clean still add sunflower lecithin, sweetener systems, or extra compounds.

Which supplements pass a strict screen, and which ones come close?

The table above uses only product details I could verify from the official pages or product-label image captured in this review.

Why does MyProtein Impact EAA Unflavoured rank first?

It ranks first because it looks like the closest match to what strict carnivore buyers want from an EAA supplement: a plain blend of the nine essential amino acids, no flavor system in the unflavored version, and a strong leucine number. The product snippet lists 2.9 g leucine per 9 g serving, which lands right in the practical leucine range many athletes target around training. That is a better label fit than products that add lecithin or extra actives. The catch is cross-contact. The page snippet says it may contain milk, soy, and gluten.

Why does BodyHealth PerfectAmino Unflavored still matter?

BodyHealth gets a high spot for one reason. It is the cleanest no-sweetener option I could verify in detail. The page says the product is pure, unsweetened, and unflavored. It lists 5 g per scoop, says the aminos are absorbed in about 23 to 30 minutes, and shows a price of $45.95 for the unflavored powder. But strict buyers need one warning. This is not a plain 9-EAA powder. It adds uridine, ATP, thymidine, adenine, and other nucleic acid building blocks. So I would call it “clean and bitter” rather than “zero-additive EAA-only.”

There is one more twist for tested athletes. BodyHealth sells an NSF Certified for Sport powder, but that version is flavored and sweetened. So the brand gives you a fork in the road: the unflavored version for label simplicity, or the NSF version for sport testing. You do not get both in one tub from the current line I checked.

Which popular powders miss the zero-additive bar?

Naked EAAs Unflavored is the best near-miss. The label image shows 50 servings, 45 calories, and a full EAA panel with 2,400 mg leucine, 1,200 mg isoleucine, 1,200 mg valine, 1,200 mg lysine, 1,200 mg threonine, 900 mg methionine, 450 mg phenylalanine, 450 mg histidine, and 250 mg tryptophan. The brand says there are no artificial flavors, sweeteners, or colors. Yet the label still lists sunflower lecithin. That one extra ingredient keeps it out of the strict top spot.

BulkSupplements EAA Powder lands in the same bucket. Search results for the official product page list sunflower lecithin as the other ingredient. That makes it unflavored, but not zero-additive. If your rule is “no sweeteners, no flavors, and I do not mind lecithin,” it still has a place. If your rule is “plain EAAs only,” it misses.

What does the new science say about dose, leucine, and timing?

The 2023 ISSN position stand gives the clearest map. It says muscle protein synthesis at rest can rise with free-form EAAs at doses as low as 1.5 to 3.0 g. It says the effect seems to level off near 15 to 18 g. It says free-form EAAs raise blood amino acid levels fast, and it says free-form EAAs can stimulate muscle protein synthesis more than an equal amount of intact protein. [ISSN position stand]

A 2024 Frontiers paper adds a useful real-world point. In 12 healthy older adults, a 3.6 g high-leucine EAA blend raised muscle protein fractional synthetic rate by 48.9% over basal values. That paper is in older adults, not lifters in a gym. Yet it still shows why small EAA doses can work fast if the blend is leucine-heavy.

Do meat and eggs still beat EAA powder for carnivore athletes?

In most cases, yes. That is the cleanest answer. A 2024 crossover trial in 16 adults aged 65 to 85 found that a beef-based meal drove 47% higher post-meal muscle protein synthesis than an isocaloric, isonitrogenous vegan meal. Plasma essential amino acid exposure was stronger too, with an incremental area under the curve of 87 versus 38 mmol·6 h/L. This was not a supplement study, but it backs a basic carnivore point: animal food still matters.

That means the best use case for EAA powder is not “replace steak.” It is “cover a gap.” Think dawn training, travel, a hard cut, or days when chewing a full meal feels rough. If your daily meat and egg intake already puts you near the protein target, skip the powder and keep the money.

What should you buy this month?

Buy MyProtein Impact EAA Unflavoured if your top rule is “closest thing to plain EAAs only.” Buy BodyHealth PerfectAmino Unflavored & Unsweetened if your top rule is “no sweeteners and no flavor system,” and you are fine with extra nucleic acid compounds. Buy Naked EAAs Unflavored only if you accept sunflower lecithin. Skip flavored versions if your whole point is a no-additive carnivore setup.
