D3K2 ReSet^®

The Bone and Immune Foundation

Food-based vitamin D3 with K2, one of the seven foundation formulas in the Maui ReSet protocol. Supports the structure and function of bone, immune, and cellular health as you age.

Bone and Structure

Vitamin D3 and K2 work together to support the maintenance of normal bones and the structure and function of connective tissue.

Immune and Cellular Support

Vitamin D contributes to normal immune function and to how cells maintain themselves over time.

A Normal Inflammatory Response

As part of the foundation stack, D3K2 ReSet^® supports a normal, balanced inflammatory response.

Science of Nutrition + Synergy

Food-based nutrients work best in concert. D3K2 ReSet^® pairs vitamin D3 with K2, and in the foundation it sits alongside the magnesium and minerals that vitamin D depends on to do its work.

Vitamin D3 and K2, Built to Work Together

D3K2 ReSet^® pairs the two fat-soluble vitamins the body uses in tandem: vitamin D3 to support normal immune function and the maintenance of normal bones, and vitamin K2 to direct that support toward the bone matrix. Pairing them in a food-based form is the sufficiency-minded way to support the structure and function of bone and connective tissue. It is the same partnership the body draws from whole foods, kept up daily as steady sufficiency rather than chased with a megadose once a shortfall sets in.

A Nutrient the Body Leans On as It Ages

Vitamin D is one of the nutrients people most often run short of, and keeping it sufficient is part of supporting a healthy aging trajectory. In the foundation, D3K2 ReSet^® supplies it alongside the magnesium it needs to activate, so the nutrients work together rather than in isolation. In older adults, vitamin D, with omega-3 and exercise, has been studied for more favorable trends in aging-related biomarkers.

How D3K2 ReSet^® Supported the Study Foundation

For six months, D3K2 ReSet^® was the bone-and-immune corner of the single daily foundation the Maui ReSet participants followed. Vitamin D works hand in hand with K2 and the magnesium it depends on, so rather than isolate any one nutrient, the pilot followed the whole foundation the way it is meant to be taken, together. The full pilot study shows how that foundation came together day by day, and what a complete, sufficiency-first six months actually looks like.

Common Questions

What do vitamin D3 and K2 do?

Vitamin D3 supports normal immune function and the maintenance of normal bones, while vitamin K2 helps direct that support toward the bone matrix. Together in a food-based form, D3K2 ReSet^® supports the everyday structure and function of bone and connective tissue as you age.

How much vitamin D3 and K2 should I take daily?

A common serving is one capsule of D3K2 ReSet^® a day, or as directed by your healthcare provider. In the Maui ReSet protocol it was taken daily alongside the other foundation formulas. Your ideal amount depends on your diet, sun exposure, and current levels, so confirm it with your provider.

Can I take vitamin D3, K2 and magnesium together?

Yes. Vitamin D actually relies on magnesium to become active, so taking them together makes good sense. In the Maui ReSet foundation, D3K2 ReSet^® sits alongside ReMag^® and the other minerals for exactly this reason, so the nutrients work together rather than in isolation as you age.

Will this lower my biological age?

No. No supplement reverses aging or changes a test result on its own, and we will not claim otherwise. D3K2 ReSet^® supports the normal structure and function of bone, immune, and cellular health. The goal is nutrient sufficiency and a healthier pace over time, followed as a trend.

What happens if you take D3 without K2?

Vitamin D helps your body absorb calcium, and vitamin K2 helps direct that calcium toward the bone matrix, where it supports the maintenance of normal bone. Pairing the two is the sufficiency-minded approach, which is why D3K2 ReSet^® delivers them together rather than vitamin D on its own.
