Organic Plant Calcium FAQ
Why should you take plant-based calcium supplements for bone health?
Why should you take plant-based calcium supplements for bone health?
Calcium is critical for multiple functions in the body—everything from strong bones and normal muscle function to blood clotting, cellular health, hormone release, and even keeping a normal heartbeat. If blood calcium levels are low due to dietary intake, then calcium is taken from our bones and used by the body—which can negatively affect bone strength. Replacing this lost calcium on a daily basis is essential to maintaining normal calcium levels in bones. That’s a great reason to seek the best calcium supplement for you!

What makes New Chapter's Bone Strength different?
What makes New Chapter's Bone Strength different?
The truth is, many calcium supplements are derived from limestone rock. This simple, rock-based calcium lacks other bone-supportive nutrients like magnesium, and may not be used properly by the body. Bone Strength Take Care is different. For our holistic bone density supplements, we use organic Red Marine Algae from the wild coast of Iceland that is rich in calcium, with magnesium and 70+ naturally occurring trace minerals. Our source of calcium is backed by 27 studies!
- Formulated for better absorption with Vitamin D3 plus K2 that guides calcium to bones—where you want it*
- The most studied form of calcium, this algae calcium has research guided by international experts in orthopedics, sports medicine, and physiology
- Slim calcium tablets are easy to swallow and have slow and steady release
