I can't speak to it's efficacy, but for me, it left a nasty after-taste, so I stopped using it. I recently started the Pauling Therapy and I can take the VitC and Lysine powder in water no problem. But this Proline tastes really awful.

I use this as part of Dr Linus Pauling's heart protocol. I am almost off my heart meds, which were affecting my ability to breathe. I wish everything came in powder form, make your own capsules, get away from magnesium stearate and silica and the like.
