As with all Functional Formularies products, we do not use any added emulsifiers or preservatives. Therefore, you  may see oil separation with our Keto Peptide formula. This is completely normal and you  do not need to be alarmed. Think of it like the organic peanut butter you buy at the grocery that has the oil on top that you have to mix back up when you get home. If you get a pouch that has separated, just reblend it in a blender for 30-45 seconds and it will be ready to use.
