BoneUp® 3 Per Day offers many of the same nutrients of regular BoneUp® but in a convenient, 3-capsule formula. BoneUp® is a comprehensive micronutrient formula that provides StimuCal™ MicroCrystalline HydroxyApatite (MCHA) and micronutrients to support bone health.* StimuCal™ MCHA is a natural source of calcium shown to support bone mineral density better than calcium carbonate.* StimuCal™ also provides bone proteins, including type I collagen.* Vitamins D3 and K2 (as natural MK-7 from fermentation) work together to support calcium deposition into bones.*
