50000 IU of vitamin d once a week enough?

I currently take 50000 iu vitamin d once weekly?

Could this amount make me feel a little weak and sickly and should I be taking more calcium,possibly a supplement with it?

Also, could this possibly be too much? or
even not enough?

Taking d2
by: Kerri Knox, RN

no one should take d2. I've gone over this on the Prescription Vitamin D page. And I have a page on pregnancy and vitamin d. Please search for it on my site.

VitD3 plus Calcium plus Magnesium Plus Omega 3
by: Anonymous

Althougth VitD is essential and a deficiency has been linked to a plethora of ills, findings show VitD3 plus Calcium plus Magnesium Plus Omega 3 are essential as well, to make it all work correctly.

My D # was 20, took prescription (the 50,000iu little blueish green pills) for 16 weeks at night before bed. After a week or two, also started taking low doses of Magnesium in a powder form (I think it's called Natural Calm, you make a tea out of), and then added Calcium Orotate. ( Orotate is the delivery mechnanism.) Then a few weeks later added a good Omega3. (D and Omega3 work together.

It has been about 8 months, 80% of my chronic fatique systems have all but disappeared, my muscle strength returned (could hardly lift a gallon of milk last year), can handle stress no problem, the BIGGEST change is I no longer use any asthma medicine. I am NO LONGER short of breath after 20 to 30 steps!!!!!! My life has turned around.

Had been using asthma meds for about 5 years....after 6 to 7 months on D (prescription) I have not had to use any asthma meds! I am absoluted amazed. Now that my levels of D are up (had another blood test), I am on over the counter D3 (between 2000 and 4000 per day, Calcium, Magnesium <300mg and Omega3. (I sometimes skip a day)

I still can't believe the difference it has made in my physical and mental (handling stress) well being. Family and friends also notice a BIG difference.

Key points

o Take the prescription D before bedtime.
o If you decide to research and take it all D,Cal, Mag & Om3, add other minerals slowly, let your body get used to one for a week or two and then add a new one the following week
o Take the time to figure out how much Magnesium and or Calcium you need.

Hope this helps.

More About Vitamin D

Those are tough questions without knowing MUCH more about your condition. Vitamin D 50,000 IU could simply be a maintenance dose for some people while it COULD be toxic to others- children, small people, or people who are out in the sun all of the time.

So, my suggestion is that you and determine your dosage from that, but be sure to read my page on Prescription Vitamin D to see why I do NOT recommend taking the prescription form, as you have most likely been given.

Could that dose make you feel "weak and sickly"? Some people may feel initially worse when they first begin to correct a long standing vitamin deficiency, but that feeling should pass in a few days to a week or two. If you are not willing to 'get through' that period of initially feeling worse, then it's possible that you may never feel better.

I don't suggest that MOST people take extra calcium except what is already in their multivitamin. Westerners get PLENTY of calcium already, for the most part, but you are asking for BIG trouble if you are taking the high dose vitamin d by itself. Vitamins are NOT drugs and should NOT be taken in high doses alone or I guarantee that you will be causing yourself to have some other deficiencies that could make you feel AWFUL.

The VAST VAST majority of problems that people have when they take vitamin d are due to an imbalance of other vitamins caused by taking the vitamin d by itself.

Magnesium deficiency, specifically, causes a LOT Of problems when people take high dose vitamin d by itself.
