Vitamin D3 + K2

What Is Vitamin D3 + K2?

Vitamin D3 + K2 by TWC provides vitamin D3 (cholecalciferol) and vitamin K2 (MK-7) together in a convenient daily capsule. This pairing is supported by a growing body of research demonstrating that D3 and K2 function synergistically — D3 promotes calcium absorption, while K2 activates proteins that direct calcium into bones and keep it out of soft tissue and arterial walls. Together, they form a foundational pair for musculoskeletal and cardiovascular wellness.*

Key Benefits

• Vitamin D3 supports immune function, mood regulation, and bone mineralization*
• Vitamin K2 (MK-7) activates osteocalcin and matrix GLA protein for calcium direction*
• Supports healthy bone density and long-term skeletal integrity*
• Promotes cardiovascular health by supporting arterial flexibility and calcium regulation*
• Features bioavailable forms for superior absorption compared to standard supplements

Who Should Take This?

Vitamin D3 + K2 is appropriate for virtually all adults, as vitamin D insufficiency is endemic in modern populations regardless of geography. It is particularly important for individuals with limited sun exposure, darker skin tone, obesity, or older age — all factors associated with reduced vitamin D synthesis. Our doctors include this among their top core supplement recommendations for the majority of patients they see.

How to Use

• Serving Size: As directed on label (typically 1 capsule daily)
• Timing: With a fat-containing meal to maximize D3 absorption
• Duration: Daily ongoing use; annual vitamin D blood testing helps optimize dose
• Stacking: Pairs with magnesium (needed for D3 activation) and omega-3s as part of a core foundational wellness protocol

Our Doctors’ Take

Our doctors consider vitamin D3 + K2 one of the non-negotiable foundations of a wellness supplement protocol — the research is compelling, the deficiency is widespread, and the safety profile of the D3/K2 combination is excellent. TWC’s formula delivers a clean, effective combination at an accessible price point that makes consistent daily use realistic for every patient. If a patient is going to start somewhere, this is often where we point them.*
