Product Description

Seeking Health Vitamin D3 K2 is a vitamin D supplement that provides 5,000 IU of highly bioavailable D2 and 100 mcg of MK+7 K2. These high quality ingredients are easily absorbed and utilized by the body.

Low levels of vitamin D can result in health issues like fatigue, mood problems, depression symptoms, low immunity, and impaired bone health. You may not even realize the vitamin deficiency because these symptoms appear over time.

Globally, 1 billion people have vitamin D deficiency and 50% of the people in the US have vitamin insufficiency. Natural dietary foods are poor sources of vitamin D. The main way to get vitamin D is through sunlight exposure. Your body produces vitamin D as your skin is triggered to create vitamin D3. But, people don't get exposed as much to sunlight due to indoor jobs and risk of high exposure to the sun's UV rays.

So, low levels of vitamin D may be because of limited sun exposure or your body doesn’t efficiently produce it. Getting your vitamin D through fortified food and supplements can be the best option to increase vitamin D levels. Seeking Health Vitamin D3 K2 provides you vitamin D3 directly and the K2 ensures that calcium absorbed goes to the bones and teeth.

Research Evidence

  • Multiple studies and trials have shown that vitamin D and K is a powerful combination. The joint supplementation of vitamins D and K may be more effective than taking them alone for bone and cardiovascular health.
  • Another randomized, double-blind clinical trial demonstrated that taking 180 µg of vitamin K2 for 3 years improves cardiovascular health.
  • A recent randomized controlled trial published in the Nutrients Journal (2025) demonstrated that 2000 IU of vitamin D3 and 240 µg of vitamin K2 for 24 weeks may help improve RECOVER long COVID Research Index score and inflammation.

By helping your body absorb more calcium and redirect it to calcium and bones, Seeking Health Vitamin D3 K2 works synergistically. Adequate vitamin D3 in the body helps absorb calcium from the food or calcium supplements you take. So, it increases calcium levels in the bloodstream.

Once calcium is in the blood, vitamin K2 directs this calcium into appropriate destinations in your body. It activates key proteins:

  • Osteocalcin: Transports calcium to bones and teeth
  • MGP: Binds calcium in soft tissues, ensuring that it doesn't accumulate in places arteries and kidneys (where you don't want excess calcium)

Without a sufficient amount of vitamin K2, vitamin D3 supports higher absorption of calcium and it may not be deposited correctly. Excess calcium floating in the bloodstream can overtime lead to potential arterial plaque, while bones remain depleted. Experts recommend that you take both D3 and K2 together for effective and correct absorption of calcium.
