I have been taking a kind of health drink cocktail mixture that comes in powder form mixed with water, and consists 3 different things: one, calcium, two, a daily Multi-vitamin drink, which is a combination of beta-Carotene, Vitamin C, Vitamin B-12, Magnesium, Zinc, Potassium etc. The third supplement I take is a powerful Bioflavonoid called OPC-3. It has very strong anti-inflammatory properties and is made of grape seed extract, Pine Bark Extract or (Pycnogenol), Red Wind Extract, Bilberry Extract and Vitamin C. Crohn's disease has a lot to do with inflammation and this Supplement seems to do a very good job of controling it. Even my joints seem to have benefited from this stuff. Formerly I had a lot of trouble with my knees. Anyway, being that it is a powder (patented and called Isotonix)that quickly disolves in water, it is actually absorbed into my stomach lining in as little as 5 minutes, where pills take hours to absorb. In my case, I had a lot of my intestines taken out, so something that is quick absorbing is very important. Heck, even my skin has taken on a smoother more youthful appearance. I'm 61. Great Stuff!!
