Dual Blend Vitamin D3 + K2
Supports strong bones, immune health and steady energy through the dark months, when the winter sun can't make vitamin D for you.†
Why trust Dual Blend
The sun can’t cover the winter.
From November, northern sun makes little or no vitamin D. One softgel with breakfast doesn’t depend on it.†
Vitamin D pulls calcium in. K2 tells it where to go.
Winter sun covers the first half poorly, and most diets miss the second half.
Why it happens
Your skin makes vitamin D3 from UVB light. From November, northern sun is too weak to make much, window glass blocks UVB, and older skin makes less from the same light.
Vitamin D’s main job is to help your gut absorb calcium. Your liver turns D3 into 25(OH)D, the level a blood test reads, and your kidneys turn that into calcitriol, the active form. The enzymes along the way need magnesium.
Vitamin D doesn’t decide where that calcium goes. That job belongs to proteins like osteocalcin in bone and matrix Gla protein in vessel walls, and they only switch on with vitamin K. K2 comes mostly from fermented foods and aged cheese, which many diets lack.

How the two nutrients work together
D3 opens the door. K2 points the way.
Vitamin D3Opens the door to calciumOnce your body turns it into calcitriol, vitamin D helps your gut absorb calcium from food and supports immune health.† Cholecalciferol is the same form your skin makes, so the softgel doesn’t depend on the season.
Vitamin K2 (MK-7)Points the calcium to boneK2 activates osteocalcin, which binds calcium into bone, and matrix Gla protein in vessel walls.† MK-7 is the long-acting form of K2: in a comparison study it gave steadier blood levels than vitamin K1.

What the K2 research foundThree years, 244 womenHealthy women after menopause took 180 mcg of MK-7 or a placebo for 3 years. The K2 group lost less bone at the spine and hip. This softgel has 100 mcg.
Knapen, Osteoporos Int 2013

Common questions
What's in each softgel?
Vitamin D3 at 5000 IU (125 mcg) and vitamin K2 as MK-7 at 100 mcg. 60 softgels per pouch.
How do I take it?
Take 1 softgel daily with a meal that has some fat, since vitamins D and K are fat-soluble. If you have kidney disease, take blood thinners, or are unsure of your vitamin D level, check with your healthcare provider first.
Why K2 with D3?
D3 supports calcium absorption, and K2 supports the proteins that direct calcium to your bones.†
Can I take it with magnesium?
Yes. Magnesium is involved in converting vitamin D into its active form, so the two are commonly taken together.†
