120 vegetarian capsules with two fat-soluble vitamins - each containing 5,000 IU of cholecalciferol (D3) and K2 in the form of menaquinone-7. The format is designed for approximately four months of daily intake.
Composition and dosage per capsule
- Vitamin D3 (cholecalciferol) - 5000 IU (125 mcg)
- Vitamin K2 (menaquinone-7, MK-7) - present in the complex
- Form: vegetarian capsules (vcaps)
- Number of servings: 120
Why are D3 and K2 combined in one formula?
Cholecalciferol increases the absorption of calcium and phosphorus in the intestines. But D3 alone does not control where calcium goes after absorption. This is where menaquinone-7 comes in: it activates proteins that direct calcium into bone tissue while simultaneously preventing its accumulation in artery walls and soft tissues.
Together, these two vitamins form a logical chain: D3 ensures the intake of calcium, K2 in the form of MK-7 determines its distribution. That is why the manufacturer Solaray combined them in one product, and not in two separate bottles.
How much vitamin D3 is 5000 IU - is it a lot or the norm?
5000 IU (125 mcg) is a dose often chosen in cases of confirmed deficiency or with minimal sun exposure. For comparison: standard preventive doses are usually 400-1000 IU per day, and therapeutic doses are from 2000 IU and above. Before taking 5000 IU for a long time, it is recommended to check the level of 25(OH)D in the blood and consult a doctor - excess D3 accumulates, unlike water-soluble vitamins.
Action of each component
Vitamin D3 (cholecalciferol)
Supports the mineral density of bones and teeth, participates in normal muscle function, and helps support the immune system. It is this form - cholecalciferol - that is synthesized in the skin under the influence of UV radiation and is considered a priority compared to D2 in terms of absorption.
Vitamin K2 (menaquinone-7)
Activates osteocalcin, a protein that incorporates calcium into the bone matrix. At the same time, it activates matrix Gla protein (MGP), which prevents calcium from being deposited in the arteries. The MK-7 form has a longer half-life compared to MK-4, so one daily capsule provides stable levels of K2 throughout the day.
How to take Solaray D3 + K2
Manufacturer's recommendation: one capsule per day with a meal. Fat-soluble vitamins are better absorbed with food containing fats - for example, during the main meal with oil, nuts or avocado. The duration and appropriateness of taking is determined by a doctor or nutritionist based on tests.
Who is this format suitable for?
Vegetarian vcaps capsules are suitable for those who avoid gelatin shells. The 5000 IU dose is relevant for people with a confirmed D3 deficiency, as well as for those who spend most of the year in regions with limited insolation or mostly indoors.
The product does not contain gelatin - suitable for a vegetarian diet. Before starting the intake, it is recommended to consult a doctor, especially when taking anticoagulants: vitamin K2 interacts with warfarin group drugs.
