I was reading it was possible to take so much vitamin c that they reach some sort of bowel tolerance, and then their body is maxed out and can have a great effect on free radicals in the body/immune strength. Has anyone dones this? I'm considering doing it?
Well, any more vitamin C per day than about 4000-5000 mg would be wasting your money. I agree that 4000-5000 is beneficial, but this may cause bowel intolerance like you say and you will have to go to the bathroom a lot.
I am glad you brought up vitamin C. There are a lot more health benefits from vitamin C than just immunity. Think of all the health ailments our western society has. The RDA is simply just enough not to have scurvy, which right now is 60 mg. However, humans are the only animal not to manufacture their own vitamin C. Now, think of all the depression, heart conditions, muscle aches and pains, cardiovascular problems, etc. There are peer reviewed and refereed journal articles relating vitamin C supplementation to the relief of those ailments. And people are not getting enough vitamin C by a long shot. So, I'm all for vitamin C supplementation and I would encourage a good quality supplement, and powder forms are good too, where you just dissolve it in a glass of water and it makes a citrus drink for you.
Another thing about RDA values, they are just set so that you don't have a deficiency. Not having a deficiency does not equate to having enough. Look at iodine. The RDA is 150 ug. However, we know that the healthiest people in the world consume around 13 mg!
I've been mega dosing on vitamin c for 6 yrs now. I will bowel tolerance every 4-6 months just to keep my levels up. Which is anywhere around 22grams to 30 grams. I've taken as much as 95 grams in 24 hrs when body was stressed. My daily dosage is 8gms to 15 grams. Divided into 3 doses.
I see family members getting sick but it just passess me bye, knock on wood.
And yes I eat lots of friuts and veggies too. When I due a vitamin c flush (BTL) I take vitamin c 2grams every half hour till a get very loose stools. Then back off the vit. c till my regular dose is due. Hope this helps.
I, too, am all for C and I think Linus Pauling was brilliant!
I do, however, take a buffered C so that I can take large doses of it without developing loose bowels. A brand I like is called Advan C. LypoSperic C is also an excellent source, but I only take it from time to time because it is very expensive.
