I'm vegan and I use hemp protein powder. It just rocks! I use it in my smoothies and it digests very well.

I know for me, I have food sensitivities to dairy, soy, and gluten, so I have to watch the commerical protein powders.

I read some place that your body doesn't make protein from protein, but rather, amino acids. So, I'm workin' on eatin' things with lots of amino acids. I researched this and discovered that dark, leafy vegetables and greens have the most amino acids...that about blew me away
