CS, is Vitamin A Safe?

I'm currently taking 13000 IU per day, at what dosage does it become dangerous? I still have a little too much sebum, can I up the dosage or not? Thanks in advance

"While often thought of as potentially toxic, Vitamin A is very safe and only toxic when consumed in amounts of 100,000 IU (International units) or more per day over several months. A daily dose of 10,000 IU is sufficient to maintain health while larger doses may be taken to overcome a deficiency.

According to the Merck Manual, vitamin A toxicity is rare. One case of vitamin A toxicity in adults was reported in Arctic explorers who developed drowsiness, irritability, headaches and vomiting, followed by skin peeling. This was not long after consuming several million IUs of vitamin A derived from polar bear and/or seal liver. The explorers soon recovered and experienced no long-term side effects.

When larger doses of vitamin A are taken in the absence of Vitamin D there have been reports of lower bone density in some cases. Conversely, high doses of vitamin D in absence of Vitamin A can also create some problems, such as immune and bone problems. This is why it is important to consume levels of each vitamin for optimal health."

Thank you tooyoung , so I can take 23000 IU per day without any trouble (I consume 2000 IU of Vit D per day)?

Dr. Mercola isn't too up to speed on vitamin A. That article came out in 2009.

I'm currently 15000 IU, so nothing to worry about with that dose? I would rather go down to 10000 IU but my softgels are 15000 IU

Fred,
I swear you've asked this same question before.

I'm not sure the when of an article is important. In 2 years a Healthy Fixx article from 2011 will not be irrelevant in my opinion.

Have you read something that comes out and suggests a dosage 10,000 IU of vitamin A? Or goes towards disproving the contention in the Mercola article that too much Vitamin A can negate the effectiveness of Vitamin D? Can you provide a link to that?

Here is an article from 2010 from Mercola on Vitamin A and Vitamin D: http://articles.mercola.com/sites/articles/archive/2010/03/16/warning-new-proof-confirms-if-you-take-this-supplement-vitamin-d-will-not-work-as-well.aspx

It's because I'm stupid.

^ That is the smartest post you've ever posted.

Go fuck yourself.

How's that one?

A lot of important research on vitamin A has been very recent, especially detailing its association with vitamin D.

Fred, 15,000 IU is no problem.

Thank you CS .

"While that may seem like both animal and plant sources provide the retinol our bodies need, it's not exactly the case. It has long been assumed that provitamin A automatically converts to retinal on demand but we now know that up to 50% of the population has a defect in the enzyme responsible for converting provitamin A to retinal. If you're only consuming provitamin A, no retinal means no retinol."

Could you please provide a reference for this? TIA

i´ve got some follow-up questions: what is a good source of vitamin a? i eat a few eggs/day but i guess thats not enough, is it? i´d probably have to eat some type of liver once/twice a week, but i really can´t be bothered. so what kind of supplemental vitamin a would you guys recommend?

It sounds like you're probably getting enough. It's okay to supplement though regardless, you'll find a link on the previous page.

thanks! you´re a wise man

i heard danny roddy is eating his eggs raw to save the vitamins etc.. are there any concerns regarding that? i read that some anti-nutrients in eggs are drawing out biotin. is that correct? i kinda feel better with raw eggs. the sulfur-smell of eggs is kinda annoying and raw eggs are pretty convenient.

Consumption of raw eggs does not prevent biotin absorption, that is a myth. Eating many raw eggs is one of the best things one can do for their health. In fact, I received a private message or two from members who have found this to be very beneficial for them.

healthyfixx is awesome! one thing that i find good about my beginning hair loss is that i started being really interested in biochemistry (which is probably neccessary when studying biology ) since i spend much of my freetime researching, i know that im on the right track with my studies..
