Prevents fractures
15 people found this helpful
Vitamin K2 aids women during menopause, helping to prevent bone loss. As calcium is leached from bones with age, supplementation with vitamins K2 and D3 can mitigate this, as well as reduce fracture risks. I take these vitamins regularly, along with a trusted manufacturer’s low pricing. My wish is that my review bolsters your decision to try them.

Calcium absorption

This combination of vitamin K2 with D3 is excellent for those needing calcium. It provides 1000 IU of vitamin D3, well above the old guidance of 400 IU. The MK-4 form of K2 ensures calcium is directed to bones and teeth without thickening the blood. I’ve noticed my child's white spots on teeth have disappeared alongside regular calcium powder use. I recommend this for anyone facing dental or osteoporosis issues.

Excellent. I trusted Dr. Karim's advice, as vitamin K2 helps transport calcium to the bones rather than leaving it in the bloodstream. It took me a while to start using it.

Vitamin K2 contributes to maintaining bone density by aiding osteocalcin, a protein that binds calcium to bone tissue, making them stronger.

Stronger nails reported
4 people found this helpful
I took this alongside Nature's Bounty’s Calcium, Magnesium, and Zinc, noticing positive results after a month. My nails have strengthened, grow faster, and retain colour. The combination with K2 facilitates D3's quicker absorption into bones. Given St. Petersburg's lack of sunlight, this supplement likely protected me from illness during the colder months.

Improved health verified

Effective vitamin K2 + D3 at a dose of one tablet daily is of excellent quality and small size. It boosts health, immunity, as well as flexibility in joints and bones. Its efficacy is proven, and deficiencies diminish with great assimilation, especially during winter when sunlight is limited. The dosage is appropriate for adults; children should use a special vitamin D3.
