Vitamins & Supplements

A calm, honest corner of the supplement aisle. We rank vitamins, minerals and popular supplements by real Amazon ratings and review volume, and we try to be straight about what the evidence actually supports, from the genuinely useful (vitamin D over a UK winter, B12 if you are vegan, creatine if you train) to the more hopeful (collagen, sea moss). No miracle claims, just the best-rated version of whatever you were already going to buy.

Common questions

Are supplements regulated in the UK?

They are sold as foods, not medicines, so they are not tested for effectiveness the way drugs are. That is exactly why we lean on real buyer ratings and stick to established brands, and why we flag where the science is thin.

Should I ask a doctor before taking supplements?

For most everyday vitamins, no. But if you are pregnant, on medication, or managing a health condition, it is worth a quick word with a GP or pharmacist, as some supplements interact or are best avoided.
