Supplements, vision products, weight-management products and fitness tech come in very different pack sizes and subscription offers, so price per serving or per unit is often a fairer comparison than the pack price. We list product details as provided by manufacturers and retailers and do not make health claims; this section is not medical advice. If you have a health condition, are pregnant or take medication, speak to a pharmacist or GP before starting a new product. Fitness trackers and smartwatches are consumer gadgets — their readings are estimates.
As retailers are connected, every offer here is ranked by its total landed price — the item price plus standard delivery — with the time each price was checked. Some retailer links are affiliate links; a commission never changes which offer we label as the cheapest.

How to choose
Choosing supplements: what to look for
Three questions to ask yourself, and the specifications that matter for each answer.
1.What are you shopping for?
- Vitamins or supplements
- Compare price per serving, and read the label and manufacturer guidance.
- Contact lenses or eye care
- Buy lenses to your current prescription from a registered seller.
2.Do you have dietary preferences?
- Vegan
- Check the label for vegan certification and ingredients.
- No preference
- Compare the number of servings per pack.
3.How do you prefer to buy?
- Larger packs for better value
- Larger packs often lower the price per serving — check the expiry date.
- Smaller packs to try first
- A smaller pack costs less upfront if you are not sure yet.
- A regular subscription
- Check the subscription terms and how to cancel before signing up.

Supplements: common questions
Do you recommend health products?
No. We compare prices and listed product details only. For advice about whether a product is right for you, speak to a pharmacist or GP.
Why compare price per serving?
Pack sizes vary, so price per serving or per unit is a fairer way to compare. We show it where retailers list enough information.
Are fitness tracker readings accurate?
They are estimates from consumer sensors, useful for following your own trends over time. They are not medical devices; for any health concern, speak to a healthcare professional.
Where does product information come from?
Product details come from manufacturer and retailer listings. Always read the label and the manufacturer's guidance.
