Vitamin D3/K2 (10,000 IU/100mcg), 120 Capsules

(5 reviews) Write a Review

The privately formulated Riordan Clinic D3/K2 supplement combines the amazing healing capacity and safety of Vitamin D and vitamin K into the convenience of one capsule to support optimal bone health.

Why Vitamin D3/K2 Capsules?

Vitamin K is essential for the proper utilization of calcium. Through its activation of the protein osteocalcin, vitamin K helps to bind newly absorbed calcium to the mineral matrix in bone. In addition, vitamin K has been found to help maintain bone mineral density by decreasing the activity of osteoclasts, a cell that breaks down the bone matrix. Therefore, vitamin K and vitamin D not only share similar qualities but they also act in synergy within the body.

A growing body of research shows that when it comes to bone health, ensuring optimal intake of vitamin K is a critical piece of the puzzle. New research is focusing on the synergistic relationship between vitamin K (specifically, vitamin K2) and vitamin D3, especially in terms of bone strength and cardiovascular health.

How does Vitamin D3/K2 Capsules aid your health?

Vitamin D is well known for the role it plays in helping to regulate calcium and bone metabolism. Vitamin D can increase the expression of osteocalcin and other important compounds from osteoblasts to help support bone formation. It can help to breakdown bone and mobilize calcium when it is needed elsewhere in the body. Vitamin K2 may play important roles in supporting cardiovascular health and normal arterial elasticity. MK-7, a natural form of vitamin K2, in particular has shown to have rapid bioavailability in the body and can be effective for supporting bone health.

The super combo of D3 and K2 ultimately promotes bone health, supports cardiovascular health and blood sugar balance, boosts immune function and supports blood circulation.

 Vitamin D3's natural partner is Vitamin K2. The genius of this combo begins with proper respect for D3's function of powerfully enhancing calcium absorption. Recent research has shown that excessive calcium intake alone can be harmful to the body. Ron Hunninghake M.D., "Lunch and Lecture: The Dynamic Duo" Health Hunters Newsletter (October 2013)

    K2 and D3

    Posted by Jan p on Apr 11th 2024

    Hi I came across this website because many companies offer this vitamin with a Macy oil that included palm oil and coconut and avocado. I’m new to this vitamin but was happy to purchase it . I don’t feel the benefits but take it daily and it’s it’s helping with my calcification and putting the calcium where it belongs instead of my arteries and heart . I love this company and the products they offer . I’m glad I found it !!!

    I was pleasantly surprised at how small these capsules are. Prior to ordering this combo, I was taking separate doses of D3 and K2, This small capsule is so much easier to take.

    I like only having to take one small pill to get both vitamins.
