The Benefits of D-3

D-3 is a vitamin that has earned the nickname of the "sunshine vitamin." When not taken as a supplement, it is usually found in animals. It is also known as cholecalciferol. Interestingly, you can also get D3 by absorbing it as sunlight, a relative rarity among humans. However, this can make absorbing D-3 naturally more of a challenge, particularly if you constantly wear sunscreen, don't get enough sun, or have darker skin, as a darker skin tone can make it harder to absorb sunlight.

D-3 works primarily by binding with the cells in your body. This has an impact on how much calcium and phosphate your body winds up absorbing - more on that later. 

 In addition to sunlight, you can get D-3 in many foods, including beef liver, butter, egg yokes, fresh salmon, and more. Indeed, many fish come loaded with D-3. However, again, if you don't eat fish, you may find yourself with a D-3 deficiency, increasing your need to take a D-3 supplement.

D-3 is important because it comes with many benefits. This includes:

  • Strengthening your bones. D-3 can increase the amount of calcium that your body absorbs. As a result, your bones can become stronger, making you more likely to break them in the event of an injury and helping to fight off other diseases, like arthritis. 
  • Protecting your immune system. Research indicates that vitamin D, in all forms, can help to strengthen your immune system and fight off many types of diseases. While no definitive conclusions have yet been reached, evidence also emerged which demonstrated that a Vitamin D deficiency increased the odds of someone getting COVID-19 and that higher levels of Vitamin D could be linked to less risk of contracting COVID-19. 

It is also worth noting that a lack of Vitamin D is associated with many negative health risks, including muscle pain and weakness, inflammation, arthritis, skin disorders, mood disorders, and more. The evidence is very clear: Vitamin D is highly useful to help ward off many types of diseases, boost your immune system, and make sure you are feeling well. 


The Benefits of K-2

Vitamin K-2 is a much more rare and under-discussed Vitamin. It is typically found in foods like animals and other fermented foods, including grass-fed cows, egg yolks, and organ meats, like liver. K2 typically comes in two different types, known as MK-4 and MK-7. 

One of the primary benefits of K-2 appears to be its ability to assist with the regulation of calcium deposits on your body. It works by strengthening your bones and teeth. It also assists in keeping calcium out of your blood vessels and helps with maintaining heart health by helping to keep your blood vessels functioning and free of calcium deposits. Indeed, higher rates of K-2 absorption are directly associated with a reduced risk of dying from some sort of heart disease. 

In addition to the obvious health and immune benefits of reducing heart disease, K-2 is also associated with improved dental health and a reduced risk of cancer. Multiple studies have found that K-2 is directly associated with a reduced risk of liver cancer and prostate cancer.

Other studies have made a more direct connection between K-2 and the immune system. For example, a 2019 study found postmenopausal women who took K2 showed inhibited T-cell proliferation, meaning that K2 could potentially boost their immune system.


Why Taking Them Together is Best

Evidence clearly indicates that D-3 and K-2 may have benefits for your immune system. However, some studies have also found that taking these two vitamins together - rather than separately - can help to boost their impact.

This effect appears tied to the way that the two vitamins work. Remember, D-3 helps to regulate the way in which your cells process calcium, while K-2 helps to regulate the way your body actually treats calcium. Taking the two vitamins at the same time can help to enhance the effect of each, ensuring a cellular synergy.

Some papers have speculated - with some evidence - that this can have a variety of impacts on your body. For example, a 2020 paper reviewed the evidence and mechanisms by which taking D-3 and K-2 may help the body fight off COVID-19, noting that there was clear evidence that these two vitamins contributed to the success and overall strength of your immune system. Reviews of this paper have noted that its conclusions are clear: K-2 intake can help to boost the impact of D-3 consumption.

These issues are particularly prevalent in western societies, as western diets tend to be low in both D-3 and K-2. These naturally occurring deficiencies make it even more clear that supplements which utilize both D-3 and K-2 are vital at this moment. The importance of taking both of these vitamins - together - has clearly grown, as some evidence suggests that COVID-19 can be fought off with the right supplements. 

As with all vitamins, you should always consult with your doctor before taking any supplements. This ensures that the vitamins you take won't interact with any medication you are taking. However, the evidence is clear: D3 and K2 have many health benefits.
