Description

You train with intention. You live with discipline. You expect your body to show up every day — stronger, faster, more capable than yesterday. But even the most dialed-in diet can leave gaps. Vitamin D levels run low in most adults. And without Vitamin K2, the calcium you absorb doesn't always end up where it belongs. So we built a solution that works as hard as you do. This high-potency formula combines:

- 5,000 IU of Vitamin D3 (Cholecalciferol) — supporting calcium absorption, immune readiness, hormone balance, and muscle function.

- 200 mcg of Vitamin K2 (as MK-7) — a clinically relevant dose that activates proteins responsible for directing calcium into bone and away from arteries.

This is the synergistic system that fortifies your structure, protects your cardiovascular pathways, and strengthens your immune resilience.

What sets this formula apart:

> Clinically relevant K2 dose (200 mcg) — double what most competitors offer

> High-potency D3 (5,000 IU) for optimal blood levels

> MK-7 form of K2 — the most bioactive and long-acting form

> Synergistic pairing for maximum calcium utilization

> Clean, disciplined formula — no unnecessary ingredients

30 capsules | 30 servings | One capsule per serving

WHY JOCKO VITAMIN D3 + K2 SETS A HIGHER STANDARD

D3 increases calcium availability. K2 ensures calcium is utilized correctly. Together: maximum bone support + cardiovascular protection. This is synergy, not just supplementation.

Bone Strength & Density

Vitamin D3 increases calcium absorption from the gut. Vitamin K2 activates osteocalcin — the protein that binds calcium into your skeletal matrix. ...

Cardiovascular Protection

K2 activates matrix Gla-protein (MGP), which inhibits calcium deposition in arteries and soft tissue. This keeps calcium out of your blood vessels ...

Immune Resilience

Vitamin D functions as a prohormone, influencing gene expression in tissues ranging from bone and muscle to the immune system and brain. It support...

Clinically Studied Ingredients

  • Vitamin D₃ — 5,000 IU (125 mcg)

    A high-potency dose of the body's preferred form of Vitamin D. Cholecalciferol is converted to calcitriol, the active hormone that binds to Vitamin D receptors in bone, muscle, immune cells, and endocrine tissues. Supports calcium balance, immune defense, muscle strength, and hormone-related health including glucose metabolism and mood regulation.

  • Vitamin K2 (MK-7) — 200 mcg

    A clinically relevant dose of the most bioactive and long-acting form of Vitamin K2. MK-7 activates osteocalcin (binds calcium into bone and teeth) and matrix Gla-protein (inhibits calcium deposition in arteries and soft tissue). This dose is double what most competitors offer — because adequate K2 activation requires adequate K2 dosing.

Frequently Asked Questions

What makes Jocko Vitamin D3 + K2 different from other D3 supplements?

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.

Why do I need K2 with my Vitamin D3?

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.

What is MK-7 and why is it better than other forms of K2?

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.

Why 5,000 IU of Vitamin D3?

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.

Why 200 mcg of K2 instead of 100 mcg like other brands?

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.

How does Vitamin D3 support immune function?

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.

Can Vitamin D3 + K2 support muscle function?

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.

When should I take Jocko Vitamin D3 + K2?

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

Is this formula suitable for athletes and high performers?

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.

Can I take Jocko D3 + K2 with other Jocko Fuel supplements?

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