Bronson Vitamin D3 5,000 IU with K2 90 mcg comes in a 120 tablet bottle, a pairing that answers a question vitamin D alone leaves open: once calcium reaches the bloodstream, where does it go? Vitamin D3 raises calcium absorption from the intestine, while vitamin K2 activates the proteins that direct that calcium into bone and restrain its deposition in vessel walls. Putting both in one tablet replaces two bottles and two separate times of day.
What are vitamin D3 and vitamin K2?
Vitamin D3, or cholecalciferol, is a fat soluble vitamin formed in the skin under ultraviolet light that passes through two conversions, in the liver then the kidney, before it becomes active. Vitamin K2, or menaquinone, is also fat soluble, produced by certain bacteria and found in fermented foods and in products from pasture raised animals, and it differs from vitamin K1, which is tied to leafy greens.
Benefits of vitamin D3 with vitamin K2
- Directing calcium to bone: Vitamin D3 raises calcium absorption while vitamin K2 participates in fixing it within bone tissue.
- Arterial flexibility: Vitamin K2 is linked to activating proteins that reduce calcium deposition in vessel walls.
- Bone density with age: Together the two vitamins are associated with mineralizing bone tissue and keeping it dense.
- Immune support: Vitamin D receptors sit on the surface of most immune system cells.
- Muscle strength and balance: Vitamin D status is associated with skeletal muscle performance and steadiness in movement.
- Dental mineralization: Vitamin K2 participates in mineralizing dentin and dental cementum alongside its role in bone.
How the combination works in the body
Vitamin K2 acts as a cofactor for gamma-glutamyl carboxylase, the enzyme that adds a carboxyl group to two specific proteins: osteocalcin, secreted by bone building cells, and matrix Gla protein in vessel walls. Without that step both proteins remain in an uncarboxylated state unable to bind calcium. Vitamin D3 runs a parallel route, converting in the liver to 25-hydroxyvitamin D and then in the kidney to its active form, which increases calcium transport across the intestinal lining into the blood. One opens the door, the other sets the destination.
What sets this formula apart
Bronson pairs 5,000 IU of vitamin D3 with 90 mcg of vitamin K2 in a single tablet, a ratio aimed specifically at people taking vitamin D at a high dose. Vitamin K2 itself comes in two meaningfully different forms: MK-4, short lived in blood and needing repeat doses through the day, and MK-7, whose longer side chain extends its stay so one daily dose suffices. The tablet carries both doses in a single unit swallowed once, and 120 tablets cover an extended period without reordering.
Who is this product for?
- People taking vitamin D at a high dose who want vitamin K2 alongside it.
- People who spend most of the day indoors, away from direct sunlight.
- People concerned with bone density as they age.
- People who prefer one tablet over tracking two separate bottles.
How to use
Take the vitamin D3 with K2 tablet alongside a meal containing fat, following the dosage printed on the product label. Both vitamins are fat soluble, so absorption improves in the presence of a fat source such as olive oil, nuts or eggs. Attaching it to the main meal of the day helps, since a fixed time is easier to keep than a separate reminder.

Frequently asked questions
What is the difference between vitamin K1 and vitamin K2?
Vitamin K1, phylloquinone, comes from leafy greens and is tied mainly to clotting factors in the liver. Vitamin K2, menaquinone, comes from bacteria, fermented foods and products of pasture raised animals, and its prominent role is in tissues outside the liver such as bone and the vessel wall.
What is the difference between MK-4 and MK-7?
MK-4 is short lived in the bloodstream and calls for repeated doses through the day. MK-7 carries a longer side chain that extends its time in blood and makes a single daily dose sufficient.
Is vitamin D3 taken in the morning or the evening?
More important than the hour is taking it with a meal containing fat, since it is a fat soluble vitamin. Many people attach it to the main midday meal simply because that is easier to keep up.
