On Vitamin A,E,D and K

[Matty D]

Hey friends,

I am living in Germany and right now I only have access to a few Vitamins from Biotics Research. I already ordered some from Haidut and am really looking forward to checking them out. But I'd like to learn more so here a few questions on the products I have...

Vitamin D emulsion:
- cholecalciferol emulsion
- emulgator: hydrated arabic gum (Acacia Senegal)
- carrier: sesame oil

Vitamin A/E emulsion:
- RE Vitamin A palmitate emulsion
- emulgator: hydrated arabic gum (Acacia Senegal)
- carrier: sesame oil
- Vitamin A
- Conservator: Vitamin E

Vitamin K emulsion:
- 500mcg Vitamin K1 (fytomenadion)
- emulgator: hydrated arabic gum (Acacia Senegal)
- carrier: sesame oil

RE Vitamin K1
This is obviously not vitamin K2 which is often talked about. What is the difference between K1 and K2?

Thanks Guys!
