How To Get Enough Vitamin D

When we think of “vitamins,” we know they’re super-important for health.  

But vitamin D is special.

It’s difficult to get enough vitamin D; vitamin D is, therefore, a very common deficiency.

So, let’s talk about how much of this critical fat-soluble vitamin we need, and how you can get enough. The three ways to vitamin D are exposure to the sun, consuming vitamin D containing food and through supplements.


Why is vitamin D important, and how much do we need?

Vitamin D helps us absorb calcium from our food and acts as a hormone to help us build strong bones. Vitamin D can also help with immune function, cellular growth, and help to prevent mood imbalances such as depression and seasonal affective disorder.

Not getting enough vitamin D can lead to bone diseases like osteomalacia. Inadequate vitamin D can also increase your risk of heart disease, autoimmune diseases, certain cancers, and even death. The “official” minimum amount of vitamin D to strive for each day is merely 400-600 IU. Many experts think that this is not nearly enough for optimal health.

To ensure you get adequate amounts of vitamin D, you can implement any combination of the three vitamin D sources mentioned above on a weekly basis.


How can I get enough vitamin D from the sun?

Your skin makes vitamin D when it’s exposed to the sun; that’s why it’s referred to as the “sunshine vitamin”. How much vitamin D your skin makes depends on many things. Location, season, clouds, clothing, excess fat and genetics all affect the amount of vitamin D your skin can produce from the sun. One standard recommendation is to get about 5–30 minutes of sun exposure between 10:00 a.m. – 3:00 p.m. to the face, arms, legs or back. This should be done without sunscreen, at least twice a week. Of course, we should always avoid sunburns and of course, in some locations (and seasons of the year) it’s not easy to get sun exposure.  So, how can we get enough vitamin D in other ways?


How can I get enough vitamin D from food?

Vitamin D is naturally found in fatty fish, liver, and egg yolks. Some mushrooms make vitamin D when they’re exposed to the sun.

Some foods are “fortified” (which means vitamin D has been added) with vitamin D. These include milk, some orange juices, breakfast cereals, and yoghurt. It will say on the label how much vitamin D has been added per serving.

Because vitamin D is fat-soluble, you can increase the absorption of it from your food if you eat it with some fat (healthy fat, of course). Between sun exposure and food, it still may be difficult to get even the minimum of 400 IU of vitamin D each day; this is why vitamin D supplements are quite popular.


How can I get enough vitamin D from supplements?

It’s easy enough to just “pop a pill” or take some cod liver oil (which also contains vitamin A). Either of these can ensure that you get the minimum amount of vitamin D, plus a bit extra.

But before you take vitamin D containing supplements, make sure you check that it won’t interact with other supplements or medications you may be taking. Always read your labels, and ask a healthcare professional for advice.

Do not take more than the suggested dosage on the label of any vitamin D supplement, except under medical care.

The maximum amount recommended (for the general population) is 4,000 IU/day. Too much vitamin D can raise your blood levels of calcium (to an unsafe level), and this can affect your heart and kidneys.

The best thing, if you’re concerned, is to ask your healthcare professional to do a blood test and make a recommendation about how much vitamin in supplement form is right for you. Your healthcare practitioner may recommend higher amounts of vitamin D supplementation for a short time while under their care.


Other Factors To Consider

The more fat tissue you have, the poorer you’ll be at storing vitamin D. Often those who are overweight need to supplement continuously to keep their vitamin D at a healthy level.

There are also genetic variations that can result in poor vitamin D storage and this is why it’s important to monitor your vitamin D level to ensure that you are supplementing enough to make a difference.

If you have a magnesium deficiency, you’ll likely struggle to maintain healthy vitamin D levels as these nutrients work synergistically. Vitamin K2 is also important for support vitamin D absorption.

Remember that a normal vitamin D blood test result is not necessarily optimal. Normal is often considered to be >50 nmol/l. However, the is plenty of research that indicates 75 nmol/l is the minimum safe level and that in fact, the higher your vitamin D, up to a level of 250 nmol/l, the more health benefits there are, especially for cancer prevention.


Conclusion:

Vitamin D is an essential fat-soluble vitamin and many people have a hard time maintaining adequate levels.  There are three ways to get vitamin D: sun exposure, through certain foods, and in supplements.

I’ve given you some ideas on how you can get the minimum 400-600 IU or vitamin D daily but many people will need more than this especially if they are already deficient. 

If you’re concerned, it’s best to request a blood test that tests your vitamin D levels to be sure what’s right for you. Always take supplements as directed.
