Vitamin D3 with Vitamin K-2 Daily - Chewable - 90 tablets

We pair them because biology pairs them

Vitamin D3 initiates: it supports calcium absorption, normal immune function, and receptors found in tissues throughout the body — including neural tissue. Vitamin K2 completes: it supports the proteins that help direct calcium toward bones and teeth, where it belongs.

One without the other is an incomplete thought. We don't sell incomplete thoughts.

Why a brain company formulates vitamin D

Vitamin D receptors are present throughout the nervous system — including in brain regions involved in regulating sleep and mood. That's why vitamin D status is part of how we think about whole-body brain health: research continues to explore its relationship to sleep quality, emotional balance, and cognitive wellness, alongside its well-established roles in immune function and bone maintenance.

Many adults get less sun exposure than their vitamin D needs assume — and spend most of the day indoors. This formula exists for exactly that gap: supporting healthy vitamin D status, so the systems that depend on it aren't running short.

What's inside — and why these doses

• Vitamin D3 — 50 mcg (2,000 IU). The body's preferred form, at a meaningful daily dose that stays within conservative clinical guidance — enough to support healthy vitamin D status without megadosing.
• Vitamin K2 as Menaquinone-7 — 75 mcg. MK-7 is the form of K2 studied for its longer activity in the body, supporting the calcium-directing proteins that make the D3 pairing work.
