NutraBio 100% Pure L-Leucine - Muscle Recovery and Support - Naturally Fermented Free Form Amino Acid - Vegan, Non-GMO, Gluten Free - (500 Grams)

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.

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.

This Leucine has lasted me a surprisingly long while. When I go to lift weights, I throw in a scoop of pre-workout as well as a scoop of this product, and you can't even taste it! Whatever you are supplementing, or drinking throughout the day, I would say anything other than coffee or water and you won't even know that this is there. With water, it's definitely not a bad taste or anything like that, if you're just sensitive to what you drink you might raise an eyebrow, literally just need like one drop of flavor. Without a doubt -- this product helps fight fatigue and muscle soreness. I would still recommend creatine first though.

I like the confidence-inspiring seals, convenient packaging, and the fact that a scoop is provided. However...One of the little plastic scoops provided is purported to be 1 serving = 3g of leucine. The problem is that 1 level scoop is simply not 3g. It's more like 2g. And if you're not being careful to fill the scoop to the brim, it's more like 1.7, or just over half a serving.In 5 trials of 3 different measurement methods on a gram scale (loose, compact, heaping) all averaged out to less than 3g (2.1, 2.7, 2.8, respectively). Based on the 'loose' measurements the scoop should be about 43% larger; a 7 or 8cc scoop is appropriate for a 3g dry-weight.

Did not "rate" flavor or thickness (irrelevant for this product). I had a much older version (same company) that I used up but I'm convinced that this version has identical nutritional value to the older one (but seems slightly more dense). I still weigh out the amount I need (typically 3g) using a very accurate scale.Note that leucine is difficult to dissolve in water, and by itself is bitter to taste. I add other ingredients as part of my homemade mix (which includes leucine) and perhaps because of the other ingredients, it mixes much easier in water.

Smells like fish and impossible to mix…..nasty stuff! This is my first L-Leucine purchase, so maybe this is expected. Either way, I don’t recommend.

Neutral taste. Does not mix well. Bought it as an extra source, but now I think I could have gotten the same from a good steak.

Add this to my protien shake for better uptake in the gut . Works for me.
