Recommend Some Supplements

Since supplements from North America cost quite literally twice as much over here. For instance Flameout on this site costs $36.99(23.39 pounds) for 90caps, over here it costs $63.26(39.99 pounds), or Surge Workout Fuel on this site $49.99(31.60 pounds) over here $86.36(54.59 pounds). Can anyone recommend supplements for us brits? particular products, brands or ingredients to look for and ingredients avoid.

I’m looking for advice on an isolate/hydrolysate protein powder, Fish oil, multi vitamin, zinc, magnesium, vitamin D, a probiotic, rhodiola rosea, and maybe HCL


Also why does it cost so much to import supplements into Britain?
