How Much Vitamin C Should I Take ? Dr.Michael Greger For many years, the RDA (the recommended daily allowance) for vitamins was just based on preventing deficiency with a margin of safety. But, the minuscule amount of vitamin C, for example, needed to avoid scurvy is not necessarily the ideal intake for optimal health. So, what might be the optimal intake of vitamin C? Let’s ask the body. How might we do that? By seeing how much the body absorbs and excretes. Experiments showing how much vitamin C our body absorbs and excretes can give us a sense of how many vitamin C rich fruits and vegetables we should be take each day.

200 mg is the best you usually get the most you need from the food you eat

Thoughts on Linus Pauling Mr. Greger? 200mg a day is a joke! nowhere near enough to prevent disease or even to treat it.

Nope, you wrong. A human body needs to take 1000 mg of Vitamin C per every 25lbs of body weight , so if a person weights 200lbs, that person needs 4000mg of vitamin C. Take 2000 mgs in the morning with a full stomach and 2000 at night with a full stomach. A great brand is NutraBio which I get on Ebay. I also take Zink and Seleniun which helps each other for better adsortion. Zink and Selenium are great for Testosterone and prostate health. I am 50 yrs old and thank God I feel great.

your math is off. 25 goes into 200 8 times, so 8000 mg per day, not 4000.

its true 5000 milligrams of vitamin c is a better option of getting rid of the flu than a flu shot This world believes every doctor they see even if they are wrong and even if it is a fact it could be false since there is never a right answer because there is no being that can Safely and fully prove anything

I have a Question what is the best time to take glutathine povidone 500mg
Dennis Price (1 год назад)
200 mg got within range of the optimal levels, 2000 mg got to the higher end, for the second chart greatest benefit was 200mg, it does show a lower risk at 1200 and 1200 absorption rate was 50 percent which is 600mg absorbed not 200, so maybe smaller amounts of c throughout the day would have some improvements. Vitamin c in large doses has been known to cure many diseases so I imagine the absorption rate would change if you were sick.

The body can absorb it and yes it does cause it to be flushed out but at a rate of taking the same amount everyday can cause it to flush less

Did you watch the video? Your body can't absorb that much so you'll just pee it out!

Smita Chakraborty I'm not a Dr but do you have any specific health conditions. It is important to get 200mg through food to minimize heart attack and stroke risk but extra vitamin c supplement can't hurt.
