There are no known significant interactions between devil's claw and a standard vitamin B complex supplement. It is generally considered safe to take these two together.
Why this happens
Devil's claw and B vitamins are processed by the body through different pathways. Devil's claw is primarily used for its anti-inflammatory properties, while B vitamins act as essential nutrients for energy and cell function. They do not interfere with each other's absorption or effectiveness.
What you should do
You can take these together as directed on the packaging. However, if you have a history of stomach ulcers or gallstones, you should speak to a pharmacist or doctor before starting devil's claw, as it can increase stomach acid.
Important precautions
Stomach ulcers or gallstones
Devil's claw can increase stomach acid and stimulate bile production, which may worsen stomach ulcers, duodenal ulcers, or gallstones.
Diabetes
Devil's claw may lower blood sugar levels; you must monitor your blood glucose closely as your diabetes medication dosage may need adjustment.
Heart rhythm disorders (arrhythmias)
Devil's claw can affect heart rate and blood pressure; use with caution if you have a heart condition or take blood pressure medication.
Food and drink warnings
Alcohol
It is best to avoid or strictly limit alcohol when taking Devil's Claw. Devil's Claw can increase the production of stomach acid, and alcohol is a known stomach irritant. Combining them may increase the risk of stomach upset, irritation, or gastric ulcers. Additionally, both substances are processed by the liver; combining them may increase the strain on liver function.
It is best to avoid or strictly limit alcohol when taking Vitamin B complex. Alcohol interferes with the absorption of B vitamins (especially B1 and B12) and increases their excretion from the body, making the supplement less effective. Additionally, chronic alcohol use can lead to severe B vitamin deficiencies.

Patient picks for Drug interactions

Can I take Iron supplements and Sedoxil together?
Taking iron supplements at the same time as Sedoxil (mexazolam) may reduce how much of the medication your body absorbs. This could make the Sedoxil less effective at treating anxiety or helping you sleep.

Can I take Flecainide and Wegovy together?
Wegovy (semaglutide) can slow down how quickly your stomach empties. This might change how your body absorbs flecainide, which is a medicine that needs to be kept at very specific levels in your blood to work safely and effectively. Additionally, both medications can occasionally affect your heart rhythm or heart rate.
