I try mixing 5g leucine in 16oz water 4x a day but the leucine doesnt mix well with the water. any suggestions?
No, it’s doesn’t mix well with water. It’s just the nature of pure leucine.
Better to mix it into protein shakes. You won’t even notice there.
Or do what I do: toss a scooper of it right into your mouth, chase it with water, swish, and swallow. Not the most pleasant method, but takes all of 3 seconds.
