What is compounding? Everything you need to know

Compounding is the custom preparation of medication by a pharmacist. Discover how it works, why it's legal, and what the advantages are compared to standard branded products.

What is compounding?

Compounding — also known as magistral preparation — is the preparation of medication by a registered pharmacist, tailored specifically to the individual patient. Instead of a standard pill from a factory, you receive a treatment that precisely matches your body, your dosage and your needs.

This is not a new concept. Before the rise of the pharmaceutical industry in the 20th century, all medicines were made this way. Today, it's a regulated practice that is growing in popularity, particularly for personalised treatments.

How does it work?

The process is straightforward:

  • A doctor assesses your health profile and prescribes a personalised treatment
  • A licensed compounding pharmacy prepares your treatment from pharmaceutical raw materials (APIs)
  • Quality control according to European Pharmacopoeia (Ph. Eur.) standards
  • Home delivery — discreet and within 2-3 working days
  • Is it legal?

    Yes, fully. Compounding is legally protected under:

  • The Dutch Medicines Act — pharmacists are authorised to prepare individual formulations
  • EU Directive 2001/83/EC, Article 3 — the magistral formula exemption
  • European Pharmacopoeia — quality standards for preparations
  • Every compounding pharmacy in the Netherlands is registered in the BIG register and is inspected by the Health and Youth Care Inspectorate (IGJ).

    What are the benefits?

    Personalised dosage

    Standard branded products come in fixed dosages. With compounding, the dosage is precisely tailored to your weight, health and goals.

    More affordable

    Branded products for weight management often cost €300-400 per month. Compounded preparations use the same active ingredients but without the brand markup — bringing the price down to from €155 per month.

    No unnecessary additives

    Commercial medications often contain fillers, colourings and preservatives. Compounded preparations contain only what you need.

    Dutch quality

    All preparations are made by BIG-registered pharmacists in licensed Dutch pharmacies, according to the strictest European standards.
