Starting from a point of education. Learning about the supplements or supplementation can be gained from one or all of Dr. J Wallach's books...start there. Dead Drs Don't Lie would be a brilliant introduction. It is advocated not what you take but what you can absorb so check out your digestive system and avoid certain foods. The supplements in powder form reminds me somewhat of powdered baby milk. However, the supplements contain much more nutrients. Personally, I find the powdered for easy to mix and bottle up so it can be consumed away from home. So far no complaints. I purchase for other members of my family whom are elderly and still able bodied and hope the supplements keeps their body maintained. Expensive? well one has to calculate the cost of other degenerative ailments due to a lack of vitamins and minerals.
