Can I take Devil's claw and Vitamin C together?

Why this happens

Devil's claw and vitamin C are processed by the body through different pathways and do not interfere with each other's absorption, metabolism, or effects.

You can continue taking both supplements as directed. However, always inform your doctor or pharmacist about all supplements you are taking, especially if you have underlying health conditions like stomach ulcers or kidney stones.

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.

Kidney stones (oxalate)

High doses of vitamin C can increase the amount of oxalate in your urine, significantly raising the risk of developing kidney stones, especially if you have a history of them.

G6PD deficiency

If you have glucose-6-phosphate dehydrogenase (G6PD) deficiency, high doses of vitamin C can cause your red blood cells to break down (haemolysis).

Haemochromatosis

Vitamin C increases the absorption of iron from your food. If you have an iron-overload disorder like haemochromatosis, you should avoid high-dose supplements.

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.

Caffeine (Coffee, Tea, Energy Drinks)

High doses of vitamin C may slightly increase the rate at which your body breaks down caffeine. This could potentially reduce the effects of caffeine, though this is usually only significant with very high supplemental doses of the vitamin.
