Vitamin A 6000IU/day

I was under the impression that this figure is more like 2500IU/day from all sources. When taken in excess of 8000IU it can cause birth defects. 6000IU seems quite high.

I read on the red marks/scars board that anything over 1gram of vitamin C was too much.

It's hard to get a clear answer, i've heard all sorts of figures.

Vitamin C is pretty useful though, and your body excretes it fairly easily. Vitmain C is an anti-inflammatory and it helps rebuild damaged skin tissues, so you're probably using alot of Vitamin C given that acne is an inflammatory disease for the most part. Plus the damaged skin needs to be repaired. It's probably fair to assume that acne sufferers need much higher amounts of Vit. C.

Vitamin Information

Vitamin A --- Male 5,000 IU per day, female 4,000 IU per day, although 10,000 IU per day is normally used in supplementation. Toxicity and symptoms of high intake....Dosages exceeding 15,000 IU per day must be taken under medical supervision. Toxicity can appear in some individuals at relatively low dosages and the symptoms may include nausea, dizziness, menstrual problems, skin changes and dryness, itchiness, irritability, vomiting, headaches and long term use can cause hair loss, bone and muscle pain, headache, liver damage, and an increase in blood lipid concentrations. Pregnant women must be careful as a high intake of this vitamin can cause birth defects.

Pro-vitamin A - beta-carotene does not cause toxicity.

Be careful if you in the unlikely event run across polar bear on a menu - 500 gram (about ½ a pound) of polar bear liver will deliver about 9,000,000 IU to your diet - a very lethal dose. Headaches, blurred vision, loss of hair, drowsiness and diarrhea, enlargement of the spleen and liver can all be indications when your intake is too high.

Vitamin E -- Males 300 iu (10 mg) per day and females 8 mg per day....Toxicity and symptoms of high intake. High intakes may induce diarrhea, nausea or abdominal wind. People on anticoagulant medication should not take more than 1,200 iu per day.

Vitamin C -- The RDA is 60 mg, per day - yet this amount will only prevent you from picking up scurvy and more recent studies suggest that an intake between 200 - 500 mg per day may be the most beneficial for healthy people. The recommend dosage for pregnant or lactating women is 75-95 mg per day. Toxicity and symptoms of high intake....Since ascorbic acid is a water-soluble vitamin, toxic levels are not built up or stored in the body, and any excess is lost mostly through urine. If extremely large amounts are taken gastrointestinal problems may appear, but will normalize when the intake is cut or reduced. To determine a level where a person might experience discomfort is difficult, since some people can easily stomach up to 25,000 mg per day, while others start having a problem at 600 or 1,000 mg.

Some people using mega dose therapy of vitamin C may have side effects such as gastrointestinal complaints including diarrhea, nausea and abdominal cramps. These side effects normally stop as soon as high potency intake is reduced or stopped.
