NOW Foods Mega D-3 & MK-7 — 5,000 IU Vitamin D3 + 180mcg K2, 60 Veg Capsules

A high-potency D3 + K2 combo from NOW Foods — 5,000 IU of vitamin D3 paired with premium soy-free MenaQ7 MK-7, for bone strength, immune health, mood support, and cycle balance.

The Supplement Most Women Are Missing

Vitamin D deficiency is one of the most common nutritional gaps in women of reproductive age — and one of the most consequential. Low vitamin D is directly associated with worse PMS symptoms, more painful periods, lower mood during the luteal phase, and irregular cycles. Most people who live and work indoors are deficient without knowing it, and a standard diet rarely provides enough to compensate.

Why D3 + K2 Together

Taking vitamin D3 alone raises calcium levels in the blood — which is the goal for bone health. But without K2, that calcium can accumulate in soft tissue and arteries rather than being directed to bones and teeth where it belongs. MK-7 (the form of K2 in this supplement) activates the proteins that guide calcium to the right places, making D3 both safer and more effective when taken together.

Why MK-7 specifically: There are two main forms of K2 — MK-4 and MK-7. MK-7 has a much longer half-life in the body (72+ hours vs a few hours for MK-4), meaning one daily capsule maintains consistently active K2 levels all day. NOW Foods uses MenaQ7 — the most researched, soy-free MK-7 available.

What This Supports

  • Cycle health — adequate vitamin D is linked to reduced period pain and more regular cycles
  • Mood and energy — vitamin D receptors are found throughout the brain; deficiency is closely tied to low mood and fatigue
  • Immune function — one of vitamin D's most well-established roles
  • Bone and teeth health — D3 and K2 work together to build and maintain bone density
  • Cardiovascular health — K2 supports healthy arterial function through proper calcium metabolism

Why NOW Foods

NOW Foods has been a family-owned supplement company since 1968. Their manufacturing carries NPA A-rated GMP certification — one of the most rigorous quality standards in the industry, covering laboratory testing, potency verification, and product formulation. The 4.8-star rating from over 6,500 reviews reflects decades of earned trust.

Good to Know

The 60-count bottle is a 2-month supply at one capsule per day. A 120-count option is available for better long-term value. Vegan capsules, Halal and Kosher certified, packaged in the USA. If you add only one new supplement this year, a quality D3+K2 is one of the most broadly beneficial choices you can make.
