Product education

Oscap®: A Comprehensive Formula for Bone Density Support*

Thorne’s Oscap® is a comprehensive bone density supplement, expertly formulated with a synergistic blend of vitamins and minerals to support skeletal health. This formula goes beyond simple calcium by providing the most absorbable forms of its key nutrients, along with the essential cofactors that help the body properly utilize them. Oscap® is designed to help maintain bone mass and strength, making it an ideal foundational choice for women, men, and any individual seeking to proactively support their bone health.*

How It Works: More Than Just Calcium

Healthy bones require a team of nutrients working together. Therefore, Oscap® provides a complete formula that supports the entire bone-building process.*

Superior Forms for Optimal Absorption
This formula features DimaCal®, a highly absorbable form of dicalcium malate, which provides a higher concentration of elemental calcium and is less likely to cause constipation than other forms. In addition, it includes Albion® DiMagnesium Malate and Bororganic™ Boron Glycinate, which are true mineral chelates that ensure maximum bioavailability.*

Synergistic Nutrients for a Strong Bone Matrix
Vitamin D3 is included to significantly enhance the absorption of calcium in the gut. But true bone health also relies on a strong, flexible protein matrix. For this reason, Oscap® includes the active forms of Folate (5-MTHF), Vitamin B6 (P-5-P), and Vitamin B12. These B vitamins are crucial for helping to maintain healthy homocysteine levels, which is important because elevated homocysteine can interfere with collagen cross-linking and weaken the bone matrix.*

  • Provides a comprehensive formula for maintaining healthy bone density
  • Features highly absorbable forms of calcium, magnesium, and boron
  • Includes Vitamin D3 to maximize calcium absorption*
  • Contains active B vitamins to support a healthy bone matrix*
  • Formulated to be well-tolerated and easy on the digestive system
