My mum might have imposed cod liver oil capsules on me when I was a little lad. Other than that, I've never taken any supplement. I want to get all I need from a mixed diet of the best ingredients I can afford, and I'll eat everything (except apple sauce: yuk). I'm wary of going short of Vitamin D in winter but the fortified cereals I eat, the oat milk and the countless eggs I consume, maybe, do the trick...
