Why choose Viworo devil's claw
- Joints and mobility. Devil's claw is traditionally associated with the wellbeing of joints, muscles and tendons.
- After physical effort. A classic for those who stay active: sport, physical work, long walks.
- 1:1 fluid extract. One kilo of root for every litre of extract: the plant stays concentrated in every drop.
- The right root. We work with the tuberous secondary roots – the part rich in harpagoside, the characteristic bitter compound.

How to use devil's claw extract
- After meals. 10 drops in a little water, twice a day.
- In cycles. Traditionally taken over periods of 6–12 weeks, ideally together with exercise.
- Diluted to taste. The flavour is strong and bitter; you can add the drops to half a glass of water.
Shake before use. Natural sediment and slight colour variations are normal in a pure plant extract.
