New to Supplements? Here Is Where to Start
You don't need a cupboard full of bottles. Here is our straightforward GP guide to choosing your daily foundation, adding targeted pouches when you need extra support, and how our value bundles save you up to 16% (up to £9.98).
3 Simple Steps to Choosing Your Supplements
Every Dr Marks formula is designed by practising UK GPs so you can start with one pouch or combine them within UK EVM and European guidance levels when used as directed, without overlapping mega-doses.
Start with One Daily Multivitamin Foundation
Rather than guessing at single vitamins, most adults do best starting with a complete daily multivitamin matched to their stage of life (Men's, Women's, Over 50s, or Pregnancy), plus daily Vitamin D in autumn and winter.
Add Targeted Pouches for Specific Goals
Because our multivitamins use balanced everyday levels, you can pair targeted pouches where your body needs more:
- Triple Magnesium: Evening muscle, sleep & nervous system support
- Omega-3 Fish Oil: Daily EPA & DHA (2 softgels daily) for heart, brain & vision
- Triple B12 / B-Complex / Vit C: Extra support for energy & immunity
Or Pick a GP Value Bundle (Save up to 16%)
Want pouches that already work together out of the box? Our 5 GP Value Bundles pair our most popular combinations with built-in savings:
- Energy & Wellbeing · Winter Immunity
- Heart & Bones · Over 50s Essentials
- Couples Multivitamin Pack (Save up to £9.98)

Even If You Don't Buy From Us — 3 Things to Check on Any Label
If you choose not to buy from Dr Marks, that's completely fine. Here are the three things our GPs recommend checking before buying any high-street or online supplement:
1. Check the Form, Not Just the Front Label
Look for nutrient forms absorbed more effectively (bioavailable) and easier for your body to use (chelated) — such as Magnesium Bisglycinate instead of cheap Magnesium Oxide, and Methylcobalamin B12 instead of Cyanocobalamin.
2. Avoid Unnecessary Tablet Binders & Glazes
Hard-pressed high-street tablets often rely on synthetic tablet binders, glazes, and talc to hold their shape. Smooth plant-based capsules (HPMC) hold pure active nutrients without synthetic glues.
3. Check Dosage & Prescription Timing
Look for meaningful daily amounts safely dosed for everyday use (within UK EVM and European UK EVM and EFSA upper guidance levels), and always check if minerals like Iron, Calcium, or Magnesium need 2–4 hours spacing from your regular prescriptions.
