the only calcium formula with more magnesium than calcium

Posted by Reviewer1583538 on Nov 21, 2010

99.9% of calcium formulas on the market have calcium & magnesium in a 2:1 ratio. This formula is the opposite ratio, with more magnesium than calcium. Virtually everyone is deficient in magnesium, NOT calcium. Magnesium is necessary to utilize the calcium in your system, as well as for MANY other functions in the body. I've been taking this formula for years. It helps prevent nighttime leg cramps, & it's critical for maintaining proper bowel function. And, as a bonus, Rainbow Light's product packaging is very eco-friendly.

This is the best combination of calcium to magnesium I've found. Glad to have it in a food based supplement.

Easy on the stomach

Rainbow light was suggested to me, by my acupuncturist here in Santa Cruz. I was having stomach cramps and indigestion problems with my over the counter drug store brand.

Helps with muscle pain

Posted by Reviewer2929277 on Jun 30, 2016

I skate commute to work and back regularly, this product helps with the muscle pain from back-to-back sessions. I also like the added vitamins and spirulina in it, for the price, I do think I'm getting a lot.
