Q: What is the typical ascorbic acid dosage for an adult?
A: The National Institute of Health has recommended a vitamin C dosage of 90 mg per day for males and 75 mg for females. However many people believe those figures are far outdated, especially for those who are under extra physical and mental pressure. Some recommend vitamin C supplements of up to 2,000 milligrams per day.
An extra 35 milligrams per day is often recommended for those whom smoke. Just to reiterate, the above figures are for adults age nineteen years and older. The recommended dietary allowance is lower for those whom are younger:
Age 14 to 18: 65 mg for females, 75 mg for males
Age 9 to 12: 45 mg
Age 4 to 8: 25 mg
Age 1 to 3: 15 mg
However you should first speak with a doctor to confirm that these doses are right for you or your child.
Mega Vitamin C Therapy
There are some, both medical professionals and everyday people, who believe that mega ascorbic acid dosage is more beneficial. These people typically consume anywhere from a few hundred milligrams all the way up to a couple thousand milligrams or more per day.
A study of more than 11,000 adult males in the United States, from 25 to 74 years of age, were used in a study conducted by the University of California Los Angeles. The study – which lasted a full decade – concluded that males who consumed 60 milligrams per day had a lifespan which was an average of six years less than those whom consumed 800 milligrams per day. However the results were highly scrutinized since supposedly the average ages in each group were different and other factors like diet were apparently not equal between the two.
Ascorbic Acid Overdose
Because it is a water soluble vitamin, it is not stored by our bodies. Rather, excess vitamin which is not needed leaves our body through urine. This is in contrast to those that are fat-soluble (like vitamin E) because our body can store them for long periods of time, therefore the chances of an overdose with a fat-soluble vitamin is much, much greater.
Because C is water soluble, it is unknown just how much would cause an overdose. Unofficially, 2000 mg per day is generally considered to be safe. Many state that excess ascorbic acid will probably not hurt most people, but it won’t give you any additional benefits either. In fact, taking super massive doses may cause digestive issues, like diarrhea. When around 10,000 or more milligrams is consumed per day, it has also been known to cause indigestion. Because it increases your absorption of iron, consuming too much has been known to contribute to an iron overload. There are other suspected conditions massive ascorbic acid dosages have been associated with also.
Not All Vitamin C Supplements Are Created Equal
Ascorbic acid is actually an artificial, fractional reproduction of vitamin C in it’s natural state (like found in fruits/veggies). Therefore, because it’s only a fraction of the natural vitamin, many speculate as to whether or not it truly works the same way. There has been compelling research which supports these claims. Because of this, more and more are turning to organic whole food supplements and all natural vitamins instead.
