Q. Im asking because I am sick so my friend gave me Emergen-C that has about 1,600% of your daily vitamin C.
I don't believe you can overdose on Vitamin C, but does your body keep absorbing Vitamin C? Or after like say a few hundred percent does your body just ignore the rest?

A. Although it is rare, vitamin C overdose is possible. Some symptoms include upset stomach & nausea. It can also sometimes cause kidney stones & copper deficiencies
Can i have improvement in my speech through better nutrition?
Q. I noticed when i started taking 65 mg of iron, it became easier for me to pronounce words and i had less soreness. I did some research online and found out that iron deficiency leads to inflammation of the tongue, nose, and face. This was consistent with the symptoms i had before and i don't have them as much anymore. Is there anything else i can do nutrition wise to improve my speech and reduce inflammation? I just bought new supplements with iron and vitamin c combined together.
A.
Can the body only assimilate 500 mg of anything?
Q. I drink 1000 mg of Vitamin C on most days, but my dad tells me that the body can only take in 500 mg.
Is this right, wrong?

A. Its neither right nor wrong - it far more complicated than that....
The amount you should take minimally is based on the amount required to prevent disease. In the case of vitamin C - the minimum amount to prevent scurvy is 60mgs.
Because humans are one of the few mammals (of four if memory serves) that do not produce vitamin C on its own, it has been theorized that we need as much other mammals that do make vitamin C - which would be the equivalent of many thousands of mg's a day - however, this obviously isn't two based on two things: 1) we would all have severe symptoms of deficiency most of the time; and 2) give most people a thousand mg's and they will have diarrhea. Loose stools are a sign you are getting to much for your body...
Vitamin C is an important nutrient when it comes to connective tissue (and 90% of your body is connective tissue of some fashion) and in various processes in the body so it was believed for a long time that we COULD use a lot of it - so its been researched - and very heavily at that - and most of the research says it's probably not a good idea to take in more than 250-500 mgs a day - that there is no additional benefit, and that there may be detrimental effects down the road.
More than what you need isn't always a good idea

Should my friend be concerned about the nutrients that she is consuming in excess?
Q. She is 20 yrs old, 5'4", 114 pounds....a year ago she weighed 120 pounds, and she has just started college. Recently she has been feeling tired and has difficulty concentrating in class.
She evaluated her diet and noticed that she consumes more than the amounts of vitamin A, vitamin C, and calcium. Her calorie intake is less than the recommended amount and, since she is losing weight is not enough to maintain her body weight. Her iron intake is well below the recommendation for women.
Is this a health risk?

Is this a health risk?
A. This is not necessarily a health risk, but there are a couple factors that you listed that need to change. Her weight at 114 is within the "normal" range; that's not a problem at all. Her goal calorie intake will significantly depend on her exercise habits. I'll list the appropriate scenarios based off of maintaining her current weight: 1530 (little or no dedicated exercise), 1750 (exercise 3 times per week), 1860 (exercise 5 times per week), 2080 (exercise everyday - everyday, no missing).
Her intake of vitamin C and calcium are of no real concern. They will not build up in her body, nor will they negatively affect her energy levels. The obvious concerns of what you've listed are her vitamin A and iron intake amounts. It sounds like you're already aware of vitamin A being a fat-soluble vitamin. If taken in excess (4,000 IU +) over a long period of time (12-15 months), it could become toxic in her body. I'm not saying that this is the case with your friend, but the levels of vitamins A, D, E, and K should be well regulated. Also, I listed the lowest precautionary level at 4,000 IU daily. People have taken doses of 100,000 IU per day and been able to reverse the toxic effect so, don't worry too much. Just get her to assess it before it becomes an issue. Her daily vitamin A intake should be around 2,300 IU or 700 mcg RE.
As for her iron deficiency, this would explain her low energy levels. This is a simple fix. I find that it's usually easier to add something to one's diet than it is to remove something. She can increase her consumption of high iron foods (red meat, fish, poultry, lentils, beans, leaf vegetables, tofu, chickpeas, black-eyed peas, too many to list) or simpler yet, she can take an iron supplement. A supplement would require no change in her eating habits. She would be more likely to accomplish this everyday. With supplementing iron, one should also increase their intake of folic acid and vitamin B-12, as iron depletes these in the body. I know of a supplement called Tri-Iron Folic that would be perfect. It's made by Nutrilite, the best in the supplement business. I personally only take their supplements because of their consistency and quality control (which are huge issues when you look into supplement companies), not to mention that they are the choice of many Olympic athletes. They are hard to find, as they are privately distributed. I get mine from a reliable source online, www.keylagohealth.com.
If your friend addresses these issues appropriately and still has similar symptoms, she should see her physician. There always could be some underlying issue that you may not be aware of.
I hope this helps.
