Vitamin D3 + K2

Two key differentiators: First, we include a clinically relevant dose of K2 (200 mcg) — double what most competitors offer. Second, we use the MK-7 form of K2, which is the most bioactive and long-lasting form. Most D3 supplements either skip K2 entirely or underdose it.

D3 increases calcium absorption, but it doesn't control where that calcium goes. Without K2, calcium may deposit in arteries and soft tissue instead of bones. K2 activates the proteins that direct calcium into your skeletal system and keep it out of your blood vessels. They work as a synergistic system.

MK-7 (Menaquinone-7) is the most bioactive and long-lasting form of Vitamin K2. It has a longer half-life than MK-4 (the other common form), meaning it stays active in your body longer and provides more consistent support for calcium-regulating proteins.

5,000 IU is a high-potency dose designed to maintain optimal blood levels of Vitamin D, especially for active individuals. Many adults are deficient, and the standard 400-1,000 IU doses often aren't enough to reach optimal levels. This dose supports bone metabolism, immune defense, hormonal balance, and muscle function.

200 mcg is the clinically relevant dose shown to effectively activate calcium-regulating proteins like osteocalcin and matrix Gla-protein. Many brands underdose K2 at 100 mcg or less. We chose efficacy over cost savings.

Vitamin D functions as a prohormone that influences gene expression in immune cells. It supports innate defenses (your body's first line of response) and helps maintain balanced immune responses, helping your body respond effectively to pathogens without overreacting.

Yes. Adequate Vitamin D helps maintain muscle strength, protein synthesis, and neuromuscular coordination. Vitamin D receptors are present in muscle tissue, and deficiency is associated with muscle weakness and reduced performance.

Take one capsule daily with food. Both D3 and K2 are fat-soluble vitamins, so taking them with a meal containing fat improves absorption.

Yes. This formula provides clinically relevant doses designed for people who demand more from their body. It supports bone density, cardiovascular health, immune resilience, hormone balance, and muscle function — foundational systems for performance and recovery. Manufactured in cGMP-compliant FDA-registered facilities.

Yes. D3 and K2 are foundational nutrients that complement other supplements. They support the structural and systemic health that enables everything else you do.
