The difference between diet pills and compounding

Diet pills vs. compounding: what's the difference? Why personalised programmes via a doctor and pharmacy are safer and more effective.

Not all weight support is equal

If you search online for help with weight loss, you'll find everything: diet pills, supplements, shakes, and medical programmes. It's important to understand the difference.

Diet pills and supplements

What are they?

Products you can buy online or at a drugstore. They often contain ingredients like caffeine, green tea extract, or fibre. They're sold as "dietary supplements" — not as medicines.

The risks

  • No medical oversight: no doctor assesses whether it's safe for you
  • No proven efficacy: supplements don't need to demonstrate effectiveness
  • Unknown side effects: the ingredients aren't always fully tested
  • No personalisation: the same pill for everyone, regardless of weight or health
  • Compounding

    What is it?

    A treatment prepared by a BIG-registered pharmacist based on a prescription from a doctor. It contains pharmaceutical active ingredients in a dosage specifically determined for you.

    The advantages

  • Medically supervised: a doctor assesses your health profile before treatment
  • Personalised: dosage tailored to your body and goals
  • Pharmaceutical quality: prepared according to European Pharmacopoeia standards
  • Regulated: pharmacy inspected by the IGJ
  • Legal and regulated: under Dutch and European legislation

    Why does compounding cost more?

    The higher price reflects:

  • The assessment by a qualified doctor
  • The individual preparation by a pharmacist
  • Pharmaceutical raw materials of controlled quality
  • Ongoing medical supervision
  • It's the difference between a self-service solution and a professional medical programme.
