Retinol (vitamin A) acetate/palmitate liquids with the fewest additives
I've been frequently asked about replacements for InterPlexus' NutriSorb A after it ran into production problems, but haven't had a good answer until recently. Now I know of a few products that I think make good replacements. They're all liquids, which is a good way to supplement vitamin A for two reasons:
- It's easy to apply topically.
- There's generally fewer excipients in both number and volume (the equivalent capsules are much larger than the typical liquid dose of a drop or two).
All three products are retinol esters. You can choose between retinyl acetate (also called retinol acetate) or retinyl palmitate (also called retinol palmitate), the form that was used in NutriSorb. I think any of them are good choices.
Suggestions for oil-based retinyl palmitate liquids:
Available at 2,500IU or 15,000IU per drop, with approximately 900 or 1,430 drops per bottle, respectively.
Retinyl palmitate, MCT (medium chain triglycerides) from coconut oil.
5,000IU per drop, approximately 340 drops per bottle.
Retinyl palmitate, tocopherols, MCT.
Suggestion for ethanol-based retinyl acetate liquid:
The ethanol solution should be particularly good for topical application.
2,400IU per drop, approximately 340 drops per bottle.
Retinyl acetate, ethanol, distilled water.
In the UK?
BioCare has a retinyl palmitate option that looks good to me:
2,500IU per drop. BioCare told me that there are 545 drops per 15 ml bottle, at least for its previous incarnation as "Bio-A".
Extra virgin olive oil, vitamin A (as retinyl palmitate), antioxidant (DL-alpha-tocopherol).
