What are Vitamin D Side Effects?
You Might be Surprised...

What are Vitamin D side effects?" you ask. Well, there are VERY few side effects of vitamin d- and most of those are very easily remedied when you know a few tricks. There is a lot of confusion about the side effects of vitamin d because so many people get SIDE EFFECTS confused with Vitamin D Overdose Symptoms . Overdose symptoms are NOT the same as side effects of vitamin d, so please be sure to read the previous page so that you understand the difference between the two.

There have been thousands of studies done on Vitamin D and the vast majority of studies state that they were astonished at the remarkable LACK of vitamin D side effects. Of course, there are ALWAYS some side effects, but even placebos (sugar pills) have side effects in studies and you must COMPARE the amount and severity of side effects to those experienced by placebo. For the most part, there just simply are no more side effects of Vitamin D than those experienced by users of placebos. But here are a few that you might experience and some help for them.

 

 


What's Magnesium Got to Do With it

In order to MAKE vitamin D in the blood, your body must USE UP magnesium. And a large proportion of people are already mildly to moderately magnesium deficient (really!). And therefore, some people who take Vitamin D and believe that they are having vitamin D side effects are ACTUALLY having Signs of Magnesium Deficiency!!


These side effects of Vitamin D that are actually magnesium deficiency symptoms are:

These vitamin d side effects can be easily overcome by taking Magnesium and Vitamin D together- with the magnesium in a dosage as outlined on the Magnesium Dosage page. But magnesium is not the ONLY nutrient required to prevent problems from taking vitamin d. It's imperative to also be sufficient in Vitamins A and K when taking vitamin D, since other problems can include issues like Pain While Taking Vitamin D, that are multifactored and may have elements that include deficiencies of many nutrients.  


How Can You Avoid Vitamin D Side Effects

It is HIGHLY recommended that with any Vitamin D regimen, you also take a full spectrum of multivitamin and minerals that include Vitamins A, K and magnesium in adequate doses that will allow you to avoid the side effects of vitamin d that are due to lack of these necessary cofactors. I recommend getting the Vitamin D Absorption Pack in order to avoid these common problems.


Quality of Pills and Ingredients

Some people get nausea, feel sleepy, get a rash or get a bad taste in their mouth. These vitamin D side effects are VERY OFTEN not due to the vitamin d itself, but due to the oil that is used as a carrier for the vitamin d! You see, most vitamin capsules are made with oil and oil can go rancid over time. Even if the capsules have a date on them, there is no way to know how long the oil was sitting around before it was packaged. If you feel sick, get sleepy, get a metallic or foul taste in your mouth or think that you are 'allergic' to vitamin d- then the very first thing to do is to change your Vitamin D Supplement to one that is either:

  • Packed in Coconut Oil- which doesn't go rancid
  • Is packed 'dry' without oil

and this might solve your vitamin d side effects.

You can get a High Quality Dry (no oil) Vitamin D Supplement here.

OR

If you have trouble swallowing pills or you are supplementing small children, there is Vitamin D in a Spray available to make things easier for you.


Muscle and Bone Pain
Are Vitamin D Side Effects

This is a side effect of vitamin d that is not so easy to remedy and is actually a sign that you really NEED TO CONTINUE taking the vitamin d. If you experience Pain from Vitamin D this very likely means that your bones have become somewhat demineralized from having vitamin d deficiency for a very long time. When your bones are demineralized and you begin Vitamin D Therapy, this can cause calcium to begin to go back into the bones. When the calcium goes into the bones it drags fluids with it. This fluid can actually cause a small expansion of the 'collagen matrix' inside the bones and this expansion pushes out against the exterior covering of the bone which is very inflexible and has extensive nerve endings.

 

 

When this occurs, you can experience this as bone pain or even muscular pain. If you experience new or worsening pain from taking vitamin d, it is NOT Vitamin D Contraindication, a reason to be scared or to stop taking the vitamin d. If you continue with the Vitamin D Therapy, the pain should subside in several weeks. While uncomfortable, you will be better off in the long run if you manage the pain for this time and 'get through' to the other side.

On the other side of the coin, most pain that people experience could very well be from a deficiency of Vitamin D. Keep reading to see why something as severe as Fibromyalgia might be from Vitamin D Deficiency!
