Hi,
My brother has been prescribed a multivitamin with the following fat soluble vitamins as ingredients for 3 weeks. Vitamin A as palmitate - 2000 iu Vitamin D - 400 IU Vitamin E - 25 IU Is the vitamin A content in this safe ? I am asking because I dont know much about vitamins. I have read a lot of vitamin A toxicity and hence I fear it. Thank you. |

You can learn about Vit A here:
http://lpi.oregonstate.edu/mic/vitamins/vitamin-A This is not a high dose vitamin supplement. The Vit A content is twice the RDA... but upper level suggested to not exceed is 10,000 in the US.

Madisongrrl,
It is very dangerous to overdose on Cod Liver Oil and organ meats. eg. Liver of bear has vitamin A in dangerous amounts. 1 gram contains Vitamin A that wud suffice for 2 years. Ingesting this amount even inadvertently can be dangerous. It will cause hypervitaminosis A. There is no treatment for Vitamin A toxicity. Even small toxic amounts take months to deplete from your body. Vit D3 supplements can be taken by properly monitoring it. I am against Vitamin A supplements. There is no definite test for Vitamin A. There is a test but that is not correct. It shows wrong values. It is good to get Vitamin A from papaya ,cantaloupe ,milk and veg dietary sources. |

Here is an article by Chris Kresser that speaks to Vitamin A toxicity/deficiency. He also explains the interplay between Vitamins A and D and talks about cod liver oil vs organ meats. He points out that you would need to eat 22 ounces of beef liver or 5 tablespoons of cod liver oil each day to create a vitamin A toxicity. I only eat liver occasionally and take 1 teaspoon of green pastures fermented cod liver oil each day because I think it is a reasonable approach. http://chriskresser.com/9-steps-to-p...lement-wisely/ I'd also recommend reading anything by Chris Masterjohn PhD on this topic; he is a expert in fat soluble vitamins.

The short term vitamin supplements that your brother has been prescribed seem very reasonable to me, provided that he is avoiding seal or polar bear livers in his diet.
