Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Joint health and inflammation, arthritis support.
  • We looked for evidence on: Osteoarthritis, Rheumatoid arthritis (RA), Back pain, Tendinopathy, Joint pain, Inflammatory arthritis.
  • The strongest evidence on file: Devil's Claw is rated "Possibly Effective" for Back pain (Natural Medicines).
  • Also on file: Devil's Claw is rated "Possibly Effective" for Osteoarthritis.
  • Also on file: Devil's Claw is rated "Insufficient Reliable Evidence To Rate" for Rheumatoid arthritis (RA), Tendinopathy.

Devil's claw is rated possibly effective for back pain and osteoarthritis based on available evidence. We don't hold enough reliable data to rate its use for atherosclerosis.

If you're considering it for back pain or joint discomfort, talk with your doctor about how it fits into your overall care plan.

The evidence, ingredient by ingredient Devil's Claw

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Devil's claw is generally well tolerated for short-term use in healthy adults, but it can cause digestive upset—diarrhea, indigestion, and stomach discomfort are the most common side effects, reported in about 8% to 18% of people in trials. Rare cases of gastrointestinal bleeding have been reported, and a small number of trial participants reported headache, ringing in the ears, loss of appetite, dizziness, or sleep problems, though it's unclear if devil's claw was the cause.

Avoid this supplement during pregnancy—devil's claw may affect the uterus and its safety hasn't been established. Also avoid it while breastfeeding because there isn't enough safety information.

If you're pregnant, nursing, or thinking about becoming pregnant, talk with your doctor or pharmacist before taking it.
