Retinyl Palmitate "poor man's accutane" has and is being used successfully to systemically treat acne at doses comparable to Isotretinoin aka Accutane (40 mg/day accuate would roughly equate to 130000 IU Vitamin A if equivalent).
Now, the UL of Vitamin A is only 10000 IU / day - all about that here: the lowest dosage where vitamin A induced liver damage was suspected divided by 5. The case in question was a woman having consumed 25000 IU/day for about 6 years. Comparing hers to other cases in the above paper, it seems to be the TOTAL amount consumed over time that matters.Her dose would then be roughly equivalent to consuming 150000 IU/day over 1 year.
So, any way to make vitamin A supplementation safer? Some ideas:
- Do 100 000 IU for 1 month and then go down to 10000 IU and hope acne stays away?
- Any liver support supplements that could mitigate vitamin A toxicity?
- Is Isotretinoin really much safer? If it is, low dose Isotretinoin > low dose Retinyl Palmitate.
- Can Vitamin A be combo'd with other supplements, e.g. Vitamin B5 to maintain efficacy and reduce risk?
Cheers!
