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.

This does not even dissolve in hot coffee. I hate it. and now I discover that it is NOT RETURNABLE! It was not opened so I feel like I was robbed by not being able to return it. I am quite furious about this!

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.

Difícil de diluir, lo que hago es echar el polvo dentro de mi boca e inmediatamente tomar un vaso de agua (tipo enjuague) así de esa manera “baja” fácilmente.
