Our maximum allowable strength Vitamin D3 plus Vitamin K2 formula offers a scientific approach to keeping you replenished with a healthy vitamin D3 and K2 balance for 4 months. ✓? BOOSTED WITH COCONUT OIL FOR HIGHER ABSORBTION - Vitamin D is fat soluble, meaning it requires fats to be absorbed by the gut. Consequently, it's a good idea to supplement with a meal containing fats. To further maximise bioavailability, we at Oxford Organics formulate with coconut oil powder, which contains LCT and MCT fats. This ensures our customers the greatest chance of positive results with supplementation. ✓? WHY VITAMIN K2 IS IMPORTANT WITH HIGH DOSES OF VITAMIN D3 - Vitamin D in high doses greatly enhances levels of available calcium within the body. However if the body doesn't have the correct balance of K2, which is essential for osteocalcin carboxylation, calcium may not be delivered to the bones, which can then become porous, and may also be deposited in the arteries, which can become calcified and increase the risk of coronary heart disease.
