We use superior science to make smarter formulas like Jarrow Formulas® BoneUp® Three Per Day. It offers the same nutrients of regular BoneUp® but in a 3-capsule formula. It provides StimuCal MicroCrystalline HydroxyApatite (MCHA) and micronutrients to support bone health and density and skeletal nutrition. StimuCal MCHA is a natural source of calcium shown to support bone mineral density better than calcium carbonate. It also provides bone proteins, including type I collagen, which is shown to support bone health. Vitamins D3 and K2 (as MK-7) are included to support calcium deposition into bones.* Adequate calcium and vitamin D as part of a healthful diet, along with physical activity, may reduce osteoporosis risk later in life.* *These statements have not been evaluated by the Food and Drug Administration.
