Vitamin C is a vital part of your daily diet since it is water-soluble and your body uses what it needs and excretes the rest. While you should get enough vitamin C from fruits, vegetables and juice, in some cases you may need to take a vitamin C supplement. Always check the expiration date on any supplement or medication.
You can get vitamin C in a variety of over-the-counter forms, including multivitamins, chewable tablets, powder and liquid solutions. Women need 75 milligrams of vitamin C daily while men require 90 milligrams, reports the Office of Dietary Supplements. Even though vitamin C is relatively safe in large doses, you should avoid consuming too much. Ingesting more than than 2,000 milligrams daily, which is the maximum amount you should have, may cause gastrointestinal distress, including gas, abdominal cramping and diarrhea.
Check the expiration on the package before you purchase it to ensure the date is not right around the corner. Expired supplements are probably safe, just not effective. Your expired vitamin C supplements may not have the same effect and benefits they did when they were fresh. Keeping them in the bathroom, where there is lots of humidity, can also affect potency by making them age sooner than the expiration date.
