Why does the USA recommend only about 60mg-100mg of Vitamin C

>Why does the USA recommend
That's a tough call. Usually I don't think of nations as being capable of recommending things beyond the expertise of the people that recommended it in the first place. Did nations attain particular agency at some point or are you just not sure where the recommendation actually originates?

>The recommended daily intake by the U.S. Food and Nutrition Board of the Institute of Medicine for men more than 18 years old is 90 milligrams of vitamin C daily

>The upper limit of intake (UL) should avoid exceeding 2,000 milligrams daily in men or women more than 18 years old

That article goes into what this thread is about. I see people who take like 6 gram per day for skin and hair lightening effects from vitamin C.

I-I am the OP..

Vitaminc C deficiencies are hardly a problem,in the US. Those recommendations are,most,likely for poorer countries where vitamin deficiences are a real concern

Vitamin C is water-soluble and as far as I've read anything over 150 is excessive and pointless.

The health benefits of vitamin C are vastly inflated. The old wives' tale that it prevents colds, or helps fight them, is a dubious claim at best, and evidence is sparse.
As long as you're not in any danger of scurvy, you're probably fine. Consuming more vitamin C than you need will have no effect.

Then put your source material in the OP next time.

Non specifying a source is a >>>/pol/-grade tactic.
