What is Vitamin D3?

Vitamin D3 is a form of vitamin D, the other forms are vitamin D1 and D2. All of them nearly have equal roles to play inside our body but when it comes to efficiency, Vitamin D3 is slightly better as it’s naturally formed while D1 and D2 are not. We obtain vitamin D from direct exposure to sunlight or from other sources like vitamins & supplements or foods containing a good amount of it.

What is Vitamin K2?

Vitamin K is a nutrient that was found to play an important role in blood clotting. In an article published by Healthline, it was revealed that the initial discovery was reported in a German scientific journal, where it was called “Koagulations Vitamin” — which is where the “K” comes from. Vitamin K mainly has two forms, and they are K1(phylloquinone) & K2 (menaquinone). K1 is mostly found in plants and leafy vegetables, while K2 is found in fermented and animal-based foods.

Vitamin K2 further has 2 more types, that are MK-4 and MK-7.

Now that you have known what vitamin D3 and K2 are, let’s look at the health benefits of Vitamin D3 and K2and how jointly they work benefitting your body.

Functions and Benefits of vitamin D3 and K2

1. Healthy Immune System

Our immune system has a very important role in defending your body from foreign, unwanted, attacking organisms that are meant to cause trouble to one’s health. To keep your immune system working properly, a number of nutrients are required. A report suggests that people with lower levels of vitamin D experienced more infection compared to people with adequate levels.  Vitamin D is the most powerful immune modulator, and its function is to normalize anything inside our body that is either too much or too little, like cytokine storm.

Our immune system makes two antimicrobial compounds and the first one is cathelicidin another one is defensin. Vitamin D is responsible for making these 2 antimicrobial compounds helpful to the immune system and in reducing inflammation. 

Vitamin K2 is also considered important for playing a role in balancing the immune system. Moreover, in many liver, lungs, and leukemia cases K2 is shown to be beneficial in killing cancer cells. 

Thus, vitamin D3 and K2 gives a healthy immune system.

2. Strengthening Bones

Our skeleton is made out naturally to give the body maximum strength. Bones are an integral part of it and are made up of calcium. Whenever our body is running low on calcium it starts to eat bone to collect calcium, thus leaving us with weak and brittle bones. Osteoblast- a cell responsible for bone formation, osteoclast- a cell responsible for the bone breakdown, these two work continuously inside our body and as long as proper vitamins like D3 & K2 are adequate in levels we are blessed with healthy bones.

Osteoblasts produce osteocalcin that is responsible for taking calcium from the bloodstream and binding that very calcium to bone for proper bone mineralization and makes the bones less prone to fracture. However, the newly produced osteocalcin from osteoblasts requires vitamin K2 to become active.

Apart from K2 vitamin D3 also has a major role to play when it comes to bone health. Vitamin D3 helps our body to absorb calcium and phosphorus effectively. Also, children and old people are at risk of low vitamin D. Osteoporosis is a condition where bones get porous and raise chances of fractures, vitamin D3 along with K2 may give you stronger and healthier bones.

3. Better Calcium Absorption

Vitamin D3 has an important role in calcium absorption, when we first consume vitamin D3 it is an inactive form to aid calcium absorption, therefore it travels to the liver and from there to the kidney where it becomes calcitriol, an active form that is helpful for absorption of calcium. As we now know that vitamin D3 is an important fat-soluble vitamin that promotes calcium accumulation so that our body does not use the bones for its bodily needs.

That’s not all, vitamin D3 without K2 can be less effective and in cases where the patient consumes a higher amount D3 can be harmful too. Think of vitamin D3 as a hero and K2 as his sidekick, K2 is responsible for guiding D3 to where it should go and it should not. When D3 is in high amounts it can accumulate into soft tissues and other places in the body where it can cause trouble for health, here K2 prevents that.

Vitamin D3 and K2 combination that is of appropriate dose may improve calcium absorption.

4. Promotes Heart Health

Vitamin K2, especially the MK-7 form is beneficial for promoting heart health. Proper levels of K2 can reduce the stiffness of arteries and also reduce arterial calcification. This helps your heart to work not much hard and saves you from risks of potential heart diseases. Vitamin D3 has been known to improve the blood pumping ability of the heart.
