Who Cannot Take Devil’s Claw? A Clear, Honest Guide Before You Use It
Devil’s Claw is one of the most popular herbal supplements used for joint pain, stiffness, and arthritis. It’s often marketed as a “natural alternative” to conventional pain relief — and while it can be effective for some people, that marketing leaves out an important truth:
Devil’s Claw is not suitable for everyone.
As someone who works in the supplement space, I believe it’s irresponsible to talk only about benefits without being equally clear about who should not take it. Natural does not automatically mean safe, and ignoring contraindications is how people end up with unnecessary side effects or complications.
This guide explains, plainly and without scare tactics, who should avoid Devil’s Claw — and why.
1. People with Stomach or Digestive Conditions
Devil’s Claw works in part by stimulating digestive secretions. That’s one reason some people report improved digestion — but it’s also exactly why it can cause problems.
You should not take Devil’s Claw if you have:
- Stomach ulcers
- Duodenal ulcers
- Chronic gastritis
- Frequent acid reflux or heartburn that is poorly controlled
In real-world use, this is one of the most common reasons people stop taking it. Stomach irritation, discomfort, or worsening reflux are not rare side effects — especially at higher doses.
Strong opinion:
If your stomach is already sensitive, Devil’s Claw is simply the wrong tool. There are other joint supplements that don’t increase gastric activity.
2. Anyone Taking Certain Medications
This is where Devil’s Claw is most often misunderstood.
Because it’s an herbal supplement, people assume it won’t interfere with medication. That assumption is wrong.
You should avoid Devil’s Claw or seek medical advice first if you are taking:
- Blood-thinning medication
- Heart or blood pressure medication
- Diabetes medication
- Anti-inflammatory or pain medication on a long-term basis
Devil’s Claw may:
- Alter how some medications are absorbed
- Increase the risk of side effects
- Compound effects, such as blood thinning or blood sugar changes
This matters particularly for arthritis sufferers, many of whom are already taking prescribed medication. Stacking supplements on top without checking interactions is not sensible — even if the supplement is plant-based.
3. People with Gallbladder Problems
Devil’s Claw can increase bile production. While that may sound harmless, it’s not suitable for people with:
- Gallstones
- A history of gallbladder inflammation
- Bile duct obstruction
In these cases, increased bile flow can aggravate symptoms or trigger discomfort.
This isn’t a fringe warning — it’s a well-established contraindication that is too often buried in small print.
4. People Scheduled for Surgery
Devil’s Claw may affect blood clotting. Because of this, it is not recommended for people who:
- Are due to undergo surgery
- Have recently had a surgical procedure
A common guideline is to stop taking it at least two weeks before surgery, but this should always be confirmed with a healthcare professional.
If you’re dealing with joint pain and also planning surgery, this is not the time to experiment with supplements.
5. People Who Assume “More Is Better.”
This isn’t talked about enough.
Devil’s Claw is often sold in high-strength formulations, and some people assume that taking more will bring faster or stronger pain relief. In reality, higher doses increase the likelihood of:
- Digestive upset
- Headaches
- Dizziness
- Interaction issues
If you’re sensitive to supplements or have had side effects from herbal products in the past, Devil’s Claw may not be appropriate — or may require a very cautious approach.
A Word for People with Arthritis
Devil’s Claw can be helpful for some people with arthritis, but arthritis sufferers are also more likely to fall into the risk groups above.
Many are:
- Taking long-term medication
- Managing multiple conditions
- Dealing with digestive sensitivity
That combination means Devil’s Claw should never be taken casually or because it was “recommended online.
Strong opinion:
If a supplement isn’t suitable for a significant portion of the people it’s marketed to, honesty matters more than hype.
Should You Speak to Your GP?
Yes — particularly if you:
- Take any regular medication
- Have a diagnosed medical condition
- Are unsure whether Devil’s Claw is appropriate for you
This doesn’t need to be a dramatic medical conversation. A pharmacist or GP can usually advise quickly once they know what you’re taking and why.
Final Thoughts: Who Should Not Take Devil’s Claw?
To be absolutely clear, Devil’s Claw is not suitable for everyone.
You should avoid it if you:
- Have stomach or ulcer-related conditions
- Take certain medications
- Have gallbladder issues
- Are you preparing for surgery
- Have a history of reacting badly to herbal supplements
Natural supplements can be powerful — and with that power comes responsibility. The right supplement, taken by the wrong person, is not the right solution.
If you want joint support, make sure it’s the right support for your body, not just the most popular option on the shelf.
