OUR GOAL
To provide the highest quality natural medicines at the lowest price.
PHILOSOPHY
Effective therapy for the patient can only be guaranteed after intervention by a specialist.
METHOD
P atients are always referred to a specialist prescriber for diagnosis and medication determination.
The NatuurApotheek then makes a custom preparation on a natural or orthomolecular basis. By continuously following the prescribed therapy with the patient, the specialist can determine whether it is desirable to repeat or adjust the therapy. With this method, the NatuurApotheek strives to bring the patient back to a healthy balance as quickly as possible.
The NatuurApotheek is a special company and a recognized pharmacy. Read more

During this five-day live course, over one hundred conditions are discussed (excluding cancer), with the best-supported treatment options for each condition based on Randomized Controlled Clinical Trials (RCTs). As a practitioner, you will gain insight into which orthomolecular remedies have the strongest scientific support for each indication.
In addition, much attention is paid to interactions between supplements and regular medication. Both positive and negative interactions are discussed. For each remedy, the possible interactions can range from a few to sometimes as many as twenty, based on RCTs or lower-level statistical evidence.
