Vitamin D3 and K2: Why You Should Never Take One Without the Other

Have you spent time taking vitamin K2-free vitamin D supplements? If yes, then you have been missing one of the major supplements that enhance the synergy of D3 and K2 vitamins. D3 and K2 vitamins are regarded as synergistic vitamins, as one without the other can be counterproductive. This paper analyses the synergy of these vitamins and their respective benefits and introduces Sainebio, a company in India that is trying to cater to the market need of providing these two vitamins in one capsule.

What Are Vitamin D3 and K2?

Vitamin D3: The Sunshine Vitamin

Vitamin D3, or "cholecalciferol", is a vitamin that the skin can make when exposed to sunlight. Cholecalciferol is vital for many bodily functions, including immune and bone health. Many Indians are vitamin D3 insufficient because their lifestyles are mainly indoors and they have both dietary and nutritional deficiencies.

Vitamin K2: The Calcium Director

One of the most essential types of vitamin K2 (vitamin K2 MK-7) has the primary function of driving calcium into the hard tissues (bones and teeth) and away from the soft tissues of the body, such as arteries and kidneys. If vitamin K2 is absent, calcium (that is absorbed by vitamin D3) is misplaced.

Why should Vitamin D3 and K2 be supplemented together?

The science behind vitamin D3 and K2 is clear:  there is D3 absorption of calcium from the gut into the blood, and without vitamin K2, the calcium in the blood is increased. This combination increases the likelihood of having blood calcium. The high calcium blood concentration increases the risk of damaging kidneys and developing calcified arteries.

Explain the combination.

Consider D3 as the nutrient that facilitates calcium absorption, while K2 acts as the traffic controller that determines its destination. Without K2 vitamin with D3, the calcium "traffic" can go to the wrong destination — your arteries instead of your bones.

●        D3 increases calcium absorption from the gut, but without K2, that extra calcium may accumulate in blood vessels rather than bones.

●        K2 activates two great proteins essential (one is needed) for D3 functions optimally: osteocalcin for calcification (bone formation) and to adjust the MGP (Matrix GLA Protein) to switch off and prevent (reverse) arterial calcification. *

Vitamin K2 7 Benefits You Should Know

When combining k2 vitamin with d3, the vitamin K2 7 benefits are amplified significantly. Here is why K2 in its MK-7 form is considered the gold standard:

Key Benefits of K2 MK-7 with D3

1. K2 prevents osteoporosis and bone fractures: K2 activates osteocalcin, a calcium ‘wielder’ protein that nets and clamps calcium onto the bones, thereby increasing the density of the support structures where it attaches.

2. K2 prevents cardiovascular disease: K2 activates MGP, allowing calcium to be ‘fenced’ off interstitial (within) arteries, thus keeping the arteries pliable (flexible).

3. K2 Prevents Jaw and Tooth Diseases: It calibrates (balances) calcium with jaw structure and strengthens the support of the tooth structure.

4. K2 Improves Immune Function: Vitamin D3 enhances immune function, whereas Vitamin K2 curbs inflammation.

5. K2 prevents the calcification of soft tissues: Vitamin K2 reduces the risk of soft tissue calcification (particularly kidney stones) by removing calcium from soft tissues.

6. K2 balances Hormones: Vitamins D3 and K2, alongside K2, influence the hormonal regulation of insulin sensitivity.

7. K2 Improves Athletic Performance: Enhanced endurance and recovery is attributed to stronger bones and a healthier heart.

Frequently Asked Questions

1). Is D3/K2 recommended?

Yes, but ideally the supplement should be taken in smaller doses. Without vitamin K2, D3 is likely to absorb calcium and create soft tissue and artery problems. So, D3 should always be combined with vitamin D3 and K2 to have a safe and effective supplement.

2). What is the ideal D₃K₂ ratio?

The recommended D₃:K₂ ratio depends on your overall health status, but generally, the K2 side is recommended to be in the range of 90 to 200 mcg (MK-7) of K₂ and 1000-2000 IU of D₃.

3). Are vitamin d3 k2 tablets  safe for everyday use?

Taking vitamin D3 and K2 tablets as recommended for everyday use is safe, as these vitamins are fat-soluble. To enhance absorption of the tablets, it is recommended to take them with a meal containing some healthy fat.

4). How long should K2 and D3 benefits last?

Most users begin to experience benefits such as improved health status, enhanced immunity, and increased energy within 4 to 8 weeks. Nevertheless, K2 and D3 benefits  related to bone health may require 3 to 6 months of use to manifest, and it is ideal to assess them through bone density scans as the time progresses.

Yes, Saine Bio's supplements are available for sale in India. Saine Bio vitamin D3 and K2 supplements  are backed by international quality assurance and are also available online.
