I'm sorry you read this junk on the internet. If topical benzoyl peroxide 5% 2x/day has not cleared you in two weeks, get with your personal physician for prescription-strength rx. Acne is a serious illness and deserves 21st-century treatment. ...Read more

What is the upper tolerable limit of Vitamin A per day?

What is the upper tolerable limit of Vitamin A per day?

10,000 iu/day but...: The official recommendation for maximum intake of Vitamin A is 10,000 iu/day though reports of toxicity generally don't occur unless people take at least 25,000 iu/day for prolonged periods.

The acute toxic dose of Vitamin A for an average adult is >660,000 units of Vitamin A, which would be 600 capsules of cod liver oil. Acute toxicity of Vitamin D in adults is generally a non-issue as it would take a massive overdose to cause acute symptoms. ...Read more

Taking more than the recommended dose of vitamins, prenatal or otherwise, is not recommended. ...Read more
