Highly bioavailable calicum supplement derived from Maerl seaweed to promote strong bones.


Highly bioavailable calicum supplement derived from Maerl seaweed to promote strong bones.

Your body requires a wide array of vitamins and minerals on a daily basis. Calcium-rich foods such as foods like milk, yogurt, cheese, leafy greens, seafood, and some fruits are a good source of calcium but, many people still don't get enough.

Dr. Peter D'Adamo, author of Eat Right 4 Your Type, developed the ClearCal natural dietary supplement to include exceptionally pure calcium derived from Maerl seaweed found only in the isolated coastal areas of southwest Ireland. This unique calcium is formulated without any additional mineral cofactors to promote a high absorption rate. It also contains a wide variety of essential nutrients and trace amounts of magnesium, boron and zinc.

Suitable for all blood types, ClearCal is 100% vegetarian and produced in a GMP quality-assured certified through the Natural Products Association. ClearCal is 100% vegetarian and is made without most of the common food allergens, and does not contain sugar, salt, gluten, wheat, yeast, corn, soy, eggs, dairy, preservatives, colors, flavors or artificial ingredients

120 vegetarian capsules
Suggested Use: Two (2) capsules twice daily as a dietary supplement.

    The best calcium supplement I've ever used. Not harsh or hard on the stomach, and easily absorbed. Highly recommended!

    Really lovely product. The effect is subtle but profound, and it treats my weird type O gut with respect. Highly recommended.

  • ClearCal to the Rescue

    Posted by Tauni Dawson on Apr 4th, 2018

    I have a food allergy to dairy products and have struggled absorbing enough calcium to make a difference in my life. Last year, I ended up in the emergency room because a kidney stone got stuck. It was determined it was a calcium-oxalate kidney stone. I read that my body didn't have enough calcium to bind with the oxalate and go through the proper channels of getting rid of it. I needed 1200 mg of calcium per day. i have tried other Calcium supplements with no success since I either got sick off of them or it was too big of a pill to swallow. Last year I started the Blood Type Diet along with taking ClearCal. I have no side effects or issues taking ClearCal and no issues swallowing it either. Per the Urologist - i no longer have any visible kidney stones either. Yeah!!!

    I've read on another website that calcium in the form of seaweed is best, so I feel good about using ClearCal.

  • Best calcium I've ever used

    I've used a ton of different calcium products over the years. For the last 10 years I have consistently come back to this one. I find I don't need to take as much and I can feel an obvious difference. If you think this product is expensive you'll find that you will actually spend less due to the potency.
