Vitamin C (this is it!)

I think I have stopped writing on here 1- been a crazy month 2 - bored of typing about vitamins! This is the last one I'll post about for a while, so we can move on to more INTERESTING topics (in my point of view).
Vitamin C:

Functions

• Also known as ascorbic acid: acts as a co enzyme that is needed to synthesize and use certain amino acids.
• Needed to make collagen - the most abundant protein in your body. Needed to maintain healthy bones, teeth, skin, and blood vessels.
• Acts as an Antioxidant, so it helps lessen the risk of chronic diseases such as heart disease and cancer.
• Helps absorb the iron in plant foods.
• Breaks down histamine (the component behind inflammation in allergic reactions).
• Boosts your immune system by enabling your body to make white blood cells which fight infections which is why many people believe vitamin c can help cure the "common cold".
  

Daily Needs

• Women need to consume 75 milligrams daily
• Men need to consume 90 milligrams daily

Food Sources

• American meet about 90% of their vitamin c needs by consuming fruits and vegetables. One serving of orange or grapefruit juice will just about meet an adult's daily needs.
  
• Tomatoes, peppers, potatoes, broccoli, oranges, and cantaloupe

Too much?
Consuming too much vitamin C (over 3,000 milligrams daily) can cause nausea, stomach cramps, and diarrhea. The upper limit for adults is set at 2,000 milligrams. Too much vitamin c can also cause kidney stones.

Where am I getting all this information? I am getting it mostly from a book titled "Nutrition and You" by Joan Salge Blake.
