Product description needed to generate the points.
Main Highlights
Vitamin D3 and K2 High Strength Capsules with No Fillers - Our clean 5-in-1 formula delivers Vitamin D3 (4000 IU), Vitamin K2 MK-7 (90mcg), Zinc, Boron and MCT oil in one daily capsule.

We've also added Boron, a mineral that helps metabolise Calcium and Magnesium. The MCT oil, extracted from coconuts, provides healthy fats essential for proper absorption of the fat-soluble Vitamins D and K2.
Pure Formula, UK-Made Quality Assurance - Unlike many competitors, our vitamin k2 and vitamin d supplements contain absolutely NO artificial fillers, bulking agents or anti-caking agents—just clean, active ingredients for optimal absorption.

Vitamin D3 5000 IU & Vitamin K2 100mcg (MK-7) x120 Capsules - High Strength Vitamin D & K2 Supplement for Men & Women, Made in the UK by Royal Oak Health
Royal Oak Health
Why we love it
Premium strength for optimal health.
Enhanced absorption, easy to swallow.
Providing four months of support.
Main Highlights
Maximum Strength Vitamin D3: Vitamin D is an essential nutrient our bodies produce naturally following exposure to UVB rays (hence the sunshine vitamin). However, during the winter months it can become difficult to maintain sufficient vitamin D levels.
