Awesome stuff, pure leucine, highly recommend.
All of the people complaining that it doesn't mix well don't realize that they are dealing with pure leucine. Pure amino acids don't mix well. If you want something that mixes well and tastes great then go look elsewhere, some place that has a ton of fillers and additives. You can't have it both ways. I'd prefer to have the unadulterated, pure supplement. I don't want people adding things to my supplements. I personally just take a spoonful straight and then wash it down with some water. Don't have to worry about mixing then. Keep up the great work, Nutrabio. Also this is completely plant-based, which is a huge plus. Don't have to worry about eating duck feathers or other garbage like that.

great product
Bought this for my husband. He said it's working well for him. Will buy more when needed. It did take a long time to get it. LOL But it was worth the wait.

Best shaken, not stirred. Needs flavor, but good for recovery.
Works well for recovery and blood flow. Only draw backs are no flavor and hard to mix. Recommend mixing with a juice or flavored drink, but shaking is the best way to mix.

Virtually unusable. Disgusting.
This product is virtually impossible to even get into my stomach. It smells and tastes absolutely disgusting. It cannot be mixed with fluids because it's hydrophobic, so you can't even tough out the vile flavor by just chugging it. It just floats and clumps and sticks to the sides of the cup; total disaster. You might try mixing it with food, but the flavor is so strong, you are liable to ruin whatever dish you mix it with. The one way I have found to tolerably consume this is by painstakingly mixing it with a large spoonful of peanut butter in a bowl, and then eating the peanut butter (better yet if you also add some agave), but adding this many calories isn't going to be for everyone, and it's a real ordeal mixing it. Do not buy this product.

Great product, good company
Outside of Thorne, Nutrabio is one of my favorite supplement companies to get my sups from. Things like Leucine here, and Glutamine. Great bang for your buck considering how much they give you and the quality of the supplements keeps me coming back. Not written by chatgpt or a bot, I just love this stuff.

Difficult to dissolve in coffee
The product is ok. However it will not dissolve in coffee easily for some reason.
