Six quick questions. We match your answers to the ingredients in every product and show you the ones that fit, with the reasons why. No email needed.
We don't make everything. We choose the best.
When a maker does one thing better than anyone else, we stock theirs instead of making our own. Every product here earned its place on dose, form and testing.
How we choose- Doctors Formulas
Doctors Formulas are designed by practising clinicians who dose for results, not for the label, in forms the body can actually use.
- Precision Formulas
Precision Formulas build around standardised botanical extracts with the active compounds measured, so every capsule delivers what the label says.

Which product should I start with?
Start with one product for your main goal and take it daily, as the label directs, for a few weeks before adding anything else. Not sure which? The two-question quiz on this page points you to the right shelf, and our protocols pair products designed to work together.
Can I take these alongside medication?
Food supplements can interact with some medicines. If you take prescription medication, are pregnant or breastfeeding, or have a medical condition, speak to your GP or pharmacist before you start. Always follow the label and do not exceed the stated dose.
