Vitamin D3 K2 Capsules - 4000 IU Vitamin D & 100mcg Vitamin K MK7 | 60 Capsules

The Crucial Role of Vitamin K2 with High Doses of Vitamin D3

Taking high doses of Vitamin D can significantly increase the amount of calcium available in the body. However, without an adequate balance of Vitamin K2, which is crucial for the activation of osteocalcin, this calcium may not be properly utilized by the bones, potentially leading to weaker bones, and might also accumulate in the arteries, raising the risk of heart disease.

Enhanced Absorption with Coconut Oil - Since Vitamin D is fat-soluble, it needs dietary fats for optimal absorption. Recognizing this, Oxford Organics includes coconut oil powder in our formulation, rich in both LCT and MCT fats, to enhance the bioavailability of our supplements, ensuring our users receive the full benefits.
Comprehensive Support in a Single Tiny Capsule - Our formulation delivers 2000% of the Nutrient Reference Value (NRV) for Vitamin D3 and 133% NRV for Vitamin K2 in a compact, easy-to-swallow capsule. This potent blend of Vitamin D3 K2 is designed to support bone, teeth, and immune health over two months with just one small capsule daily.
Rigorous Lab Testing for Optimal Efficacy - Oxford Organics is committed to excellence and transparency, rigorously testing our formulas twice — once during manufacturing and again by an independent third-party laboratory. This ensures the purity and potency of our products, aligning with our mission to deliver high-quality supplements. Our products are proudly manufactured in the UK, exceeding local and EU standards in BRC Grade AA facilities.
Our 100% Satisfaction Guarantee - We invite you to become part of the Oxford Organics family, a community dedicated to improving wellness. We're so confident in the quality of our Vitamin D3 with K2 capsules that we offer a lifetime 100% money-back satisfaction guarantee.

Description

How to get the best results

Consistency makes a difference, really!

Taking your daily serving consistently helps support balance over time, with effects that tend to build rather than show up all at once. Making it part of your routine is what allows those changes to add up.

A subscription is the best way to keep things on track - no need to remember to reorder, and no interruptions to your routine (and it's more cost effective with 20% off included).

"Your body is remarkable. Our job is simply to give it what it needs - purely, precisely and without compromise."

Dom Haines

Chief Nutrition Officer

Formulated by British nutraceutical experts.

There's a difference between a supplement that looks impressive and one that actually performs. We build for performance, always.

The proof of any formula isn't on the label - it's in how you feel at the end of the week, the month, the year. That's the only standard we build to.

Every formula respects your body's natural processes. Gentle where it needs to be. Powerful where it counts. Never more than necessary. Never less than effective.

Designed for your body, not for the label.
