Barefoot coral calcium popularity problemThe only problem is it’s become so popular, that it’s now a big business. There is so much misinformation out in the market and so many unethical companies trying to make a quick buck. Bob Barefoot estimates that 90% of the coral calciums in the US market are the low-grade beach (rock, or fossilized) coral harvested from the beaches as compared to the high grade marine coral harvested from the ocean floor. Marine grade coral is 24% calcium and 12% magnesium, the perfect (2:1) nutritional ratio for maximum calcium absorption. Beach coral or fossilized coral is 37% calcium and less than 1% magnesium. |
