EstroBan, a Vitamin A, D, E, and K "multivitamin" with no unnecessary ingredients

Update 10/4/2016: I suspect that some kind of degradation occurs when mixing vitamin E and K, making me think it's preferable to take your fat-soluble vitamins separately if you don't mind the hassle.

I think personal investment is important in supplement manufacturing, so I was pleased to see a Ray Peat Forum member creating his own Vitamin A/D/E/K supplement.

Here's the entire ingredient list which avoids the unnecessary excipients common to other fat-soluble "multivitamins":

• Vitamin A (retinyl acetate). 5,000IU per serving.
• Vitamin D3. 1,000IU per serving.
• Vitamin E (mixed tocopherols, so it contains alpha, beta, gamma, and delta). 65mg per serving.
• Vitamin K2 (menatetrenone, MK-4). 2mg per serving.
• Organic olive oil
• Organic coconut oil

The container is, I believe, HDPE plastic (a good choice with regards to leaching anything).

It's only available in a liquid form, but the taste isn't too objectionable. If you've ever tried other vitamin E liquids (or progesterone in vitamin E oil), the taste is similar.
