Vitamin D3 and K2, two crucial nutrients that are fat-soluble and are not produced by the body itself. This article will make you aware regarding the sources of above-mentioned vitamins and 5 important tips on choosing the right supplement.

What is Vitamin D3 And K2?

Vitamin D3 is another form of vitamin D and it is the most effective & beneficial form. Vitamin K2 is another nutrient that is important for playing various health-related roles for you. Vitamin K2 also has 2 other forms that are MK-4 and MK-7. MK-7 is the healthiest form because it is highly bioavailable to the body. These 2 nutrients have quite a work together to perform, like improving bone health, supporting immunity, and much more. Check out our previous blog where we have discussed their potential benefits in detail. 

Vitamin D3 and K2 Benefits


Lets, look over on how to get vitamin D3 with K2. Yes, by that we mean sources of it.

Sources of Vitamin D3 and K2       

Vitamin D3 and K2 can be obtained through a number of sources. Basically, there are 2 sources, 1) Through food 2) Through dietary supplements.However there is a primary source other than these two for vitamin D3, and yes you have guessed it right it is the sun.

Sun Light

Vitamin D is also known as ‘Sunshine Vitamin’ because sunlight is the primary source of vitamin D. When your skin is exposed to direct sunlight, UVB rays turn into vitamin D in your body. It is the easiest way of acquiring vitamin D. However, due to changes in our lifestyles, it is getting harder even to sit for half an hour in the sunlight. As we work inside an office that barely has any direct sun rays, we drive cars with our windows shut and away from sunshine. 

Though it is the easiest source of vitamin D, sunburn, a permanent tan, dead skin cells, and most importantly skin cancer are potential risks of exposing your skin to direct ultraviolet rays.



1. Foods

There numerous foods that are a good source to satisfy your vitamin D3 and K2 combination needs. But some foods are common while the rest are unlikely to be in an average person’s diet. Anyway here is the list.

Vitamin K Sources

2. Supplements

In the market, there are hundreds of dietary supplements available that are processed to be rich in vitamin D3 with K2. It is the best way to acquire vitamin D3 and K2 benefits but wait, with every good thing a little bad always comes. Not all the supplements are beneficial and helpful like the way their manufacturers portray, some can cause you serious health deteriorating side effects due to their improper and immoral way of manufacturing. We intend to help you choose the right supplement with these 5 helpful tips.

1.Efficiency & Quality 

The first and foremost thing when considering to use vitamins and supplements, evaluate a little bit about the supplement you are planning to buy. As we take an example of vitamin D3 and K2 supplements, some supplements may contain either vitamin D2 or D1 along with K1 instead of K2, well they are not exactly the vitamins you are looking for. As the other forms of vitamin D and K compared with D3 and K2 are less effective. Always lookout for the exact form of supplements as alternative forms may not be so beneficial.

LeoNutra uses the proper form of vitamin D3 with K2 in proper proportion so that you may acquire optimum benefits.

2. FSSAI Mark

According to the jurisdiction of India, “The FSSAI has been established under the Food Safety and Standards Act, 2006, which is a consolidating statute related to food safety and regulation in India. FSSAI is responsible for protecting and promoting public health through the regulation and supervision of food safety.”

This statement clears the doubts regarding safety and various standards by which a supplement should abide just like supplements manufactured by LeoNutra does. Look on the backside of the bottle you will see an FSSAI logo which means it is approved by FSSAI. 



3. GMP Mark

Here is another mark you should keep an eye on when selecting a supplement. GMP or Goods Manufacturing Practices is one type of system that works to keep a pre-decided standard for any pharmaceutical products. Also, they take care of the production of the product and asks for documents that can prove the production procedures goes by their standards for a quality product. 

Good Manufacturing Practice


4. Dosage

IU (International Units) is a measuring unit used for medicines, vaccines, vitamins & supplements, and other similar biologically active substances. IU is an easy yet trusted source to know the proper amount of ingredients used in supplements as IU is practiced universally, thus creating no problems when compared with other supplements. 

5. Ingredients

Ingredients are the core part of any supplement, therefore it is advisable to take a closer look at the list of ingredients, as some of you may be allergic to an ingredient used in the making of the supplement or you are looking for a supplement that avoids using a certain ingredient in it. It’s better to know that the product is vegetarian or vegan friendly or it is non-vegetarian. Nowadays people tend to look for supplements that are free from gluten, dairy products, animal products, gelatin, or anything else that may not be beneficial.
