There is a great misunderstanding about vitamins and minerals among most people today. One large part of misinformation is the RDI “Recommended Daily Intake” and RDA ” Recommended Daily Allowance.” Most people believe that this is the most or highest levels of any vitamins and minerals that can be taken safely. This would be completely wrong!! If that were the case, the abbreviation would be MDI ” Maximum Daily Intake” and MDA “Maximum Daily Allowance.” The truth is, these are actually the Minimum dose of these important vitamins and minerals you must have to ensure you do not get the disease or pathology associated with that vitamin or mineral. For example, If you do not get the required dose of 90mgs per day for an extended amount of time, you could get scurvy. Remember your history? James Lind who first proved it could be treated with citrus fruit in experiments he described in his 1753 book, A Treatise of the Scurvy, though his advice was not implemented by the Royal Navy for several decades. So what does this mean? If you eat more that one fruit or go over the RDI you will get sick? No way!!! Linus Pauling “who was a brilliant Biochemist used to take over 10,000mgs per day and was just fine. Vitamin C is sometimes used by homeopathic doctors to treat and cure types of skin caner with intravenous vitamin C and use upwards of 100,000mgs to 210,000mgs. That goes right into your bloodstream and there is a report of feeling lightheaded and/or nauseous. There are no other side affects associated with this treatment. Its a dirty little secret a lot of people don’t want you to know. To be a bit more specific, it would be very difficult to overdose or get sick taking large amounts of Water soluble vitamins. However, The fat soluble vitamins you should be aware of and those can can be dangerous in large doses. Remember, there are regular doses and clinical doses. Be sure you consult a Clinical nutritionist when taking large doses of any vitamins or foods. “WARNING!” A nutritionist and a Clinical Nutritionist are two different things. Be sure you see a Clinical nutritionist!!! The education is more detailed.
