Am I Vitamin D Toxic

I have been taking 50,000IU once a week for three weeks. After just my first dose I was experiencing bad muscle aches, stomach cramps and severe fatigue. Negative for mono and lyme.

Could this be from too much vitamin D?

You Are Not Toxic...
by: Kerri Knox, RN- The Immune Queen!

First of all, you can rest assured that you are NOT VITAMIN D TOXIC. I guarantee it, it has never happened on 150,000 IU's of vitamin d ever in history. Ever.

I am 100% sure that you are not vitamin d toxic!

OK, so what's going on. First of all, it's likely that you were quite vitamin D deficient for you to get put on prescription vitamin D. And sometimes, your body has some drastic biochemical changes in calcium metabolism when that happens, particularly if you are VERY vitamin D deficient.

Second, you are taking prescription Vitamin D, which is Vitamin D2. And researchers have stated unequivocally that Vitamin D2 should not be used for supplementation. You can read about why this is on the Vitamin D2 vs Vitamin D3 page.

So maybe it is the Vitamin D2 that you are having problems with and not the 'vitamin d' per se.

So, what to do? You NEED vitamin D and once you are vitamin D sufficient, it's not likely that this will be a problem, so first of all:

Dump that prescription Vitamin D and get some Good Quality High Dose Vitamin D3. These come in a dose of 5000 IU's per capsule. Start out taking 1 capsule per day and work up to 2 capsules per day.

That's a total of 10,000 IU's per day. That's a little more than your prescription, but it is a completely safe and effective dose to bring your Vitamin D Levels up.

Make sure that you take your pills with food because vitamin D needs fat in order to be absorbed and may be a little easier on your stomach getting it with food.

AND, finally make sure that you continue the 10,000 IU's per day and INSIST on another vitamin D level in 3 months in order to determine how you are progressing. You MUST get retested!!!

Whatever you do, you need to get your levels up and you need vitamin D to do it. If you live in a sunny area, you can also expose as much skin to the sun as possible for as long as possible without burning. This will get your levels up quickly and effectively as well.

Vitamin D3
by: Lesley

I have a Vit D deficiency (I have just been diagnosed with osteoporosis) and plan to take 1,2000mg calcium, 600mg magnesium, 1,000 iu Vit D3 and K2 100 mcg per day.

The doctor will be repeating the blood test for Vit D in three months time.

Once the levels are up, do I have to continue taking Vit D3? I am worried about the long term effects and also possible calcium problems (kidney stones).

strange choices for your treatment...
by: Kerri Knox, RN- The Immune Queen!

Hi Lesley,
I'm not sure how you came up with those dosages, but they are a bit strange. So, first of all, the calcium dosage is OK- I'm not big on calcium, even for osteoporosis, but most doctors recommend it and I'm not going to tell you to NOT take it, but calcium is less important for your bones than the magnesium and vitamin d.

Next, you should not have a preconceived notion about how much magnesium you'll be taking. Everyone's magnesium needs are VASTLY different and you should read the page to determine how much magnesium to take.

600 mg is a good place to START with magnesium, but it's possible that you could need nearly twice that.

Then about the vitamin d. 1000 IU's is a MAINTENANCE dose for a newborn infant, it is NOT a treatment dose for an adult. Please read the Vitamin D Deficiency Treatment page to see that your 1000 IU's needs to be increased by 7 to 8 TIMES that dose in order to treat deficiency.

And from what I have learned of vitamin d- there are ZERO long term negative effects from taking vitamin d- it does NOT increase the chance of kidney stones. The long term effects of not getting ENOUGH vitamin d, such as:

Symptoms of Fibromyalgia

Many Types of Cancer

Breast Cancer

It's one of the Causes of Heart Failure

and SOOOO much more. Vitamin D is a NUTRIENT- it is NOT a drug. You will need vitamin d for the rest of your life. And the fact that you have osteoporosis and are vitamin d deficient right now is proof that your lifestyle is NOT including appropriate intake of vitamin d.

Think of vitamin d as something as important as water. If you were diagnosed with dehydration and you go to the ER and get your body 'filled up' with fluids. You don't ask the doctor how long you'll need to keep drinking water after going home because the answer is "Forever".

You need water and vitamin d forever.

vit d3, calcium and magnesium
by: peggy

Hi, I am currently taking 1,000 iu D3 per day, 1,200 iu calcium peer day and 125 iu magnesium per day. is it ok to take these all together at breakfast? I also take 1200 mg fish oil in the morning. along with prescribed meds for Bi-polar disorder.

That depends...
by: Kerri Knox, RN- The Immune Queen!

Hi Peggy,

That depends upon what, exactly, you are trying to accomplish by taking that regimen of vitamins.

Please read the Vitamin D Requirements page to see that your dosage of vitamin d that you are taking is the amount that doctors familiar with proper vitamin d intakes are recommending for newborn infants- and what surprising adult dosages are recommended.

Next, please read the Magnesium Dosage page to see why 125 mg of magnesium is so low as to be simply worthless- plus I imagine that your calcium and magnesium are the incorrect TYPE of vitamins that are not even being absorbed anyway!!

So, if you are trying to accomplish longer term health, maintaining bones, getting cancer protection, etc- then the regimen that you are doing will NOT accomplish that.
