There's absolutely zero evidence that taking more than 100% of your daily required amount of any vitamin is effective for anything. Your body simply cannot absorb or make use of it. What you've described may very well be a placebo effect.

Take a daily supplement which ensures you are getting a sufficient amount, and nothing more. Anything beyond that is literally getting flushed down the toilet in your urine.

I know from experience that megadosing vitamin C is a sure fire way to get hot flushes and diarrhoea. Probably not the results people are after though!

I take your point, but I think it's important to say that this isn't strictly true. Your daily requirement is what you need for normal functioning, not what you can absorb.

For vitamin C, this isn't a huge distinction - it's water soluble, and the excess will be flushed, as you say. But for fat soluble vitamins, you absolutely can absorb more than a 100% dose. This is usually bad, and comes about from things like home overdosing or extremely narrow diets. It's occasionally medicinal, though, with something like isotretinoin being very similar to a major overdose of vitamin A.

I wouldn't suggest overdosing on vitamins to anyone unless a doctor tells you do, but it's worth noting that it does cause an effect - usually a bad one.

You're parroting the official medical position which has not been revised in decades. There's a lot of opinions on the web based on incomplete science. I read a lot about it, and in the end decided to try it.

Who cares if it's a placebo, as long as it works I'm taking it.

For the record, homeopathy did absolutely nothing for me, so I'm not sure I have much of a placebo gullible body ;-)

Yes, because it's proven basic science.

And I'm a living example disproving your basic science. Some days I can get by with 2 grams, some other days I need up to 10 grams to shut symptoms.

If it was a placebo, why would I need varying doses to suppress symptoms and why homeopathy didn't work as a placebo ?

Then explains me why vit C works better than regular medicine for my allergies (no symptom at all with vit C but they are just reduced by half with antihistamines).
