PlantFusion

PlantFusion Vegan Calcium, Premium Plant Based Calcium (1000mg) Sourced from Icelandic Red Algae, Plus Magnesium, D3, K2, and Boron, 90 Vegan Tablets

Free Shipping

Main Highlights

PLANT BASED CALCIUM MAGNESIUM: We start with a scientifically validated and trademarked source of calcium/magnesium concentrated to 1000mg per serving. We then add plant based vitamins D3 and K2 for calcium assimilation and critical trace minerals like strontium and boron which help form the bone matrix. Altogether more than a dozen different supplements in one. We call this the ultimate Fusion for bone health!
SOURCE MATTERS MOST: This ultra-premium plant based calcium and magnesium supplement is made from a unique trademarked ingredient called Aquamin. Aquamin is a nutrient dense form of algae grown in the pristine nutrient rich waters off Iceland. Calcium and magnesium from Icelandic red algae is a higher quality source of these minerals that is more absorbable in your body. This allows you to take a smaller dose than you might with synthetic forms of calcium for easy digestion.
D3, K2, BORON & STRONTIUM: Bone growth is a complex process that requires many different nutrients. Thats why our formula contains over 12 different supplements in one. These include plant based vitamin D3 & vitamin K2, plus the minerals boron and strontium which all play a role in creating the bonds that form our bone matrix for optimal bone density and strength.
CLEAN BONE SUPPORT FORMULA: We only use minerals that are tested for heavy metals, vegan certified, non-GMO verified, dairy free, gluten free, soy free and that contain no artificial ingredients or chemicals.
THE PLANT BASED EXPERTS: PlantFusion was one of the pioneers of plant based supplements over a decade ago. All products are produced under cGMPs (current Good Manufacturing Practices) and adhering to US FDA guidelines. All ingredients and finished goods are subjected to rigorous 3RD party analytical testing.
