I have to admit that I’m not as knowledgable on vitamins as I probably should be - but isn’t 5000 IU’s of Vitamin D3 a little on the high side?

Is there a point where your body doesn’t absorb vitamins when they reach that high of a level?

Sometimes I take 6-7K if the flu is sweeping through town. The problem with the gubmint recommendations is that they recommend what is normal for a perfectly healthy person who eats a perfectly balanced meal and gets the perfect amount of exercise a day. That is not me. Of course I do eat healthfully and I choose organic food, preferably from my back yard, and local meats without added ammonia, but our diets are still lacking in many vitamins. Many of us are vitamin D deficient and don't know it, so taking more than the gubmint recommendation is necessary. If you are frequently ill, that is a sign that you might have a deficiency. Ask your doc for a test.

I forgot to add sunlight. SPF 5000 is now en vogue. Unless we are outside for more than one hour, we do not use sunblock and my 2 1/2 year old has never had a sunburn. Our bodies need the vitamin D that the sun naturally provides us. Plus it’s free! So many children are sick more often, and it’s not just because of daycare depots. Part of the problem is that their mommies slather them with chemical sunblocks for a trip to the mailbox.

With vitamin d, you need to get tested to see what your blood level is. When you get to a therapeutic dose in your bloodstream, you will no longer get sick with viruses and you will be preventing cancer and a host of other things.

I got tested in a hot summer month when I was getting sun exposure, and was already taking 2000 units of d3. My level was 25, far too low. I upped my dose to 10,000 units and after a few months, went back and my level was still too low at 45. I now take 15,000 units a day. A therapeutic dose brings your blood level up to 60. Maybe you only need 500 units.every human is different.
