Talking a dose of 200mg or less your body will absorb up to 98%. Taking a dose of 1,000mg your body will only absorb up to 33%, before the excess is eliminated in the urine.

Up until fairly recently (evolutionarily-wise) people didn't cook their food, even proteins. Meat was often eaten raw or smoked, and as the animal's flesh was saturated with vitamin C, we also would have ingested that. Diets high in berries and root vegetables were the norm, as were such delicacies as grubs, an animal loaded with the vitamin C of its plant-based diet.

Advance forward to the last 50 years or so, and all proteins are cooked, destroying most of their nutrients, and 'veggies' are packaged boxes of something or another, and sugar intake has gone from a pound in an entire lifetime, to a pound a month or so... and vegetables are grown in nutrient-deprived soils.

Our diets in the last 50 years or so have undergone more change then in the 10,000 years before that. Who knows how many diseases are increasing concurrent with the decreasing quality of our diets?

The knee-jerk debunking never ceases to amaze me. Hey, information is all good; take it all in, consider it, and let others do the same. One thing I learned early on in the medical field; most doctors NEVER ask a patient what their normal diet is like on a daily basis; they all figure that everyone eats like they do. Nutritional education in most med schools consists of mere minutes...

Maybe an inability to consider new information is caused by vitamin deficiencies...

A tolerable upper limit (UL) of vitamin C was set at 2 grams for the first time in the year 2000, referencing this mild laxative effect as the reason for establishing the UL. … Stone and Pauling calculated, based on the diet of primates (similar to what our common ancestors are likely to have consumed when the gene mutated), that the optimum daily requirement of vitamin C is around 2,300 milligrams for a human requiring 2,500 kcal a day.

Vitamin C is a strong anti-oxidant and as such, degrades rapidly. There are a number of factors that contribute to our inability to obtain sufficient quantities naturally.

1. The fresh produce we eat is not fresh enough. By the time it gets into our mouths, the food has lost most of it's VC.

2. The modern food we grow has been bred to minimise VC content in an effort to make it more appealing to our palates.

2. Our palates develop from early childhood to accept sweet and salty foods. Foods high in VC are usually sour, astringent which our palate rejects.

3. Our daily requirement for VC varies depending on the environmental stresses we experience.
Our modern immune systems have not matured fully due to our diet and medical intervention. This places the immune system under greater stress than would otherwise be.
Our modern lifestyle is more emotionally stressful, which further suppresses our immune systems and other physiological systems.

For most of us, the requirements for VC in our modern world far outweighs the ability for our modern diet to supply.

Remember VC is an acid. Many minerals (like Zinc) are metals. What does acid do to metals (think battery acid and the body of your car)? What do you think happens when an acid and a metal are combined in a pill?

So how do you get 98% from 200mg, but only 33% from 1,000mg ?

So, the difference between the USDA guidelines and this study is only 300mg? That doesn't seem like enough to really make a big stink over.
