KD Ultra

KD Ultra by Arthur Andrew Medical combines 2500 IUs of vegan vitamin D3 with a full-spectrum blend of the available Vitamin K2 chains (referred to as menaquinones) MK4, MK6, and MK7 (MKs) as well as Vitamin K1 for the ultimate health benefits of each component.

However, because Vitamins D and K are fat-soluble (meaning they dissolve in fat), we added the enzyme [lipase] to break down ingested fats, allowing your body to properly release the vitamins from fat and absorb them efficiently. That means no more missing out on all the perks of taking your vitamins!

Vitamin D3

Our formula includes vegan vitamin D3 (the natural form produced by the skin upon exposure to sunlight) from reindeer lichen. Vitamin D regulates calcium and phosphorous levels to support and maintain strong bones. It also plays a role in calcium absorption, bone health, and immunity.

Vitamins K and D have a synergistic relationship that promotes strong bones and cardiovascular health. If you don’t include both in your supplement routine, you could be missing out! That’s why we formulated KD Ultra to include everything you need for broad-spectrum benefits in a single supplement.

What is the difference between vitamin D2 and vitamin D3?

These two forms of Vitamin D were thought to be equivalent, however, that is far from the truth. Vitamin D2, or ergocalciferol, is inexpensive to produce and almost always what is found in fortified foods. It is actually less potent and has a shorter duration of action than its Vitamin D3 counterpart known as cholecalciferol.

According to a research study, health professionals increased testing for Vitamin D sevenfold between 2008 and 2013, and it’s thought that over 1 billion people are deficient in this vital nutrient.

What are lichens you ask?

Lichens are naturally occurring organisms found throughout the world and can best be described as a fungi-algae sandwich, two different organisms that live together as one. The fungi actually protect the algae which allows lichens to grow in some of the most extreme environments the world can offer.

A majority of supplemental Vitamin D3 is chemically stripped from lanolin, a yellow waxy oil found in sheep’s wool and then irradiated to produce D3. KD Ultra uses a naturally derived D3 from lichen, a much cleaner and natural form of this vital nutrient.

Vitamin K

Vitamin K comes in many forms and is essential for proper Vitamin D utilization. Our formula includes Vitamin K1 as well as all available supplemental forms of Vitamin K2 (MK4, MK6, and MK7) for full-spectrum health benefits. Vitamin K supports proper blood health, strong bones and cardiovascular health.

In addition, adequate vitamin K is actually necessary to get the health benefits we’ve all come to know about vitamin D.


Lipase is an enzyme that breaks down lipids (fats) and fat-soluble vitamins. Without enough lipase, fats cannot be fully broken down and properly absorbed by the body. This may limit the benefits you expect to get from taking your vitamins. Lipase is essential for complete vitamin assimilation, which is why we have included it in our proprietary formula.


Take 1-2 capsules daily of KD Ultra, or as directed by your healthcare practitioner. If taking more than one capsule, they may be split up and taken with each meal, or taken all at once. For best results, please refer to the guide below or as directed by one of our health coach professionals.


Do not take KD Ultra without the consent of your physician if you are currently taking anti-coagulants, or if you are pregnant or nursing.


Store in a cool dry place with lid tightly closed.
