Overview

A 240-tablet bottle pairing 1200mg of calcium with vitamin D3 in an unflavored tablet, labeled gluten free, dairy free and non-GMO, aimed at daily bone health support for adults.

Many calcium tablets leave out vitamin D3, which the body needs to make use of calcium, so combining both nutrients in one tablet simplifies the daily routine. This formula also carries gluten free, keto, paleo, plant based and vegetarian diet tags, plus a dairy, lactose and non-GMO allergen profile. The label lists teeth health alongside bone strength and immune support as intended uses.

  • 1200mg calcium with vitamin D3 per serving
  • 240 tablets per bottle
  • Gluten free, dairy free, lactose free, non-GMO
  • Fits keto, paleo, plant based and vegetarian diets

Who it's for

Adults looking for a straightforward calcium and vitamin D3 tablet, especially those following gluten free, vegetarian or plant based diets. Less suited to anyone needing a chewable or liquid format instead of a tablet.
