Is Vitamin D3 Good For You?

Is Vitamin D3 Good For You?


On a daily basis, we muddle through our alphabet of vitamins to try and consume enough for our bodies to function healthily. It can be a confusing task, as some vitamins come in easier forms than others, a classic example of this is Vitamin D. A vitamin that can be found in small amounts in food but our best option seems to be mainly from the sun.


While vitamins A, B, C, and E can be found more abundantly in food, the number of vitamin D in foods is minimal. Meaning, we don’t consume enough to obtain the recommended amount. This makes the known fact of 75% of people having a vitamin D deficiency, pretty understandable.


This “sunshine vitamin” is absorbed through the skin. Yale Medicine Dermatologist David J. Leffell, MD explains that “We each have vitamin D receptor cells that, through a chain of reactions starting with conversion of cholesterol in the skin, produce vitamin D3 when they’re exposed to ultraviolet B (UVB) from the sun.”Therefore, when we sit in the sun, our skin essentially produces vitamin D.


However, this is not always an easy task for some, and can depend on where in the world you are living, the overall climate, what type of day it is or even your specific skin type. So, if you're out there thinking you may not be getting enough sun or consuming enough vitamin D rich foods, supplements are inevitably a great option to look for.



What are the Benefits of Vitamin D3?


Vitamin D is not only found in nearly every cell in our bodies but can potentially impact almost 2000 different genes. It demonstrates the potential to make changes to our bodies at a cellular level, as once vitamin D binds to a receptor, it can turn our genes on or off. Through studies, NCBI was able to find that “any improvement in vitamin D status will significantly affect the expression of genes that have a wide variety of biological functions. Of more than 160 pathways linked to cancer, autoimmune disorders and cardiovascular disease which have been associated with vitamin D deficiency.”


This process leads to the benefits of vitamin D3 including:

Bone Health

D3 leads to strong and healthy bones due to being able to help regulate calcium and phosphorus. This, in turn, leads to bone growth and formation.

Boosts Mood

With our brains containing vitamin D3 receptors, an insufficient amount can bring our mood down. This can be seen when many people deal with the winter blues as they lose their source of the sun. Since D3 can aid in the creation of neurotransmitters, which help regulate our mood, we are able to fight off negative emotions like clinical depression.


For those with diabetes, D3 does a lot more to help you than you may believe. By stimulating the pancreas, D3 triggers the process to make insulin. This is very important in managing blood sugar levels.

Heart Health

By regulating blood sugars, D3 can support heart health. Lower levels of vitamin D have been seen to increase the possibility of heart attacks, although there isn’t a clear-cut reason as to why.


Studies have shown that vitamin D3 could potentially slow down the progression of cancer or combat certain forms of cancer, specifically breast, colon, and prostate cancers. Despite much more research being needed, it is seen that with D3 aiding in the regulation of cell growth, it could slow down any new blood vessels in cancerous tissue.  


Immune System

Maintaining adequate levels of vitamin D3 will also benefit your immune system, calms your blood pressure, and can even see you having better results in the gym.



Vitamin D3 Deficiency Symptoms


A deficiency in vitamin D3 can mean many things, and research has strengthened throughout the years as doctors come to terms with how severe a deficiency in D3 can be.

Healthline lists the symptoms as being:

Becoming sick or infected often
Fatigue and tiredness
Bone and back pain
Impaired wound healing
Bone loss
Hair Loss
Muscle Pain


Vitamin D deficiency is incredibly common, however, most people aren’t always aware that they are having any severe issues. This is due to some of these symptoms being subtle or potentially linked to other health issues you may have. On the same note, these symptoms can increase in risk over time if not dealt with, so speak to your doctor if you believe you may be deficient in this imperative vitamin.



How much Vitamin D3 Do I need?

The recommended daily allowance (RDA) will depend on your age bracket. For most people, 600 IU per day will be sufficient. This is due to age affecting our ability to synthesize vitamin D and absorb calcium.


Keep in mind, that too much of something can be a bad thing too. This is very true when it comes to overdosing on vitamin D. So much so, that if your levels become far too high, the outcome could be dangerous. states that overdoses could cause “nausea, loss of appetite, thirst, urinating more or less than usual, body aches, stiffness, confusion or irregular heartbeat.”



Vitamin D3 foods

As stated previously, vitamin D3 is found in certain foods, however, the amounts are smaller than what we would like and we often don’t consume enough of the foods to reach our RDA. The consumption of vitamin D also becomes a little tricky if you are on a vegetarian or vegan diet as egg yolks in free-range eggs, mushrooms and cereals are literally the only non-meat foods with vitamin D.


As for those on a traditional diet, vitamin D can be found in oily fish like herring, swordfish and cod liver oil. For the rest of your vitamin D foods, you’ll be looking at fortified foods, which manufacturers add to commercially available foods, such as milk, orange juice and certain breakfast cereals.


Because of the lack of vitamin D3 found in foods, it could be vital for you to start reaching for a supplement. Therefore, if it is winter, bad weather, or your finding your not consuming enough vitamin D3 in your daily diet, consider supplementing it with our 2 in 1 Support K2+D3. Our supplement will also give you vitamin K2 which will benefit your bones by aiding you in absorbing calcium and receding calcium plaque in your arteries.

Vitamin K2 D3


The vast variety of vitamins we must consume in a day is incredibly important and despite our sources of vitamin D being more on the minimal side, it’s just as important to make sure we are getting enough. With better moods, stronger bones, and a boost in heart health, there is no reason to not start focusing now.
