A combination of Fish Oils and Vegetable Oils put together for us by Lee Jackson. Basically this is the ultimate nutritional bulk oil for use in any type of mix, not just fishmeals. We sell The Complete Food Oil in 250ml bottles, so you can keep it as fresh as possible. This product should be kept refrigerated at all times. Dosage is relatively low for a bulk oil – 10-15ml per 16oz/500g.
