What are the side effects of Nervecept?
The side effects of Nervecept are unknown as a product, because no trial has tested the capsule. What exists is a set of cautions for its eight ingredients.
Which ingredient causes which side effect?
Each ingredient has its own caution, and several overlap on the stomach.
| Ingredient | Caution |
|---|---|
| Glucosamine 500 mg | Shellfish-derived; may raise blood sugar; warfarin caution (NCCIH, Glucosamine and Chondroitin) |
| Boswellia 67 mg | Stomach upset, skin allergy (Tavakoli et al., Boswellia adverse events) |
| Turmeric root 50 mg | Bleeding risk; liver injury with enhanced products (NCCIH, Turmeric) |
| Bromelain 8 mg | Stomach upset, diarrhea |
| Quercetin 8 mg | Kidney disease and drug processing (VKM, Rutin and Quercetin supplements) |
Who should be careful with Nervecept, and which signs need a doctor?
Anyone with a shellfish allergy, on a blood thinner, or with diabetes, liver or kidney disease should be careful. The label also says to ask first if pregnant, nursing or under 18.

See a doctorAny of these, or tingling that is getting worse, is a reason to see a doctor. Many causes, such as diabetes or low B12, can be treated, and early treatment protects nerves. A supplement should not delay it.
Go nowNumbness with weakness, trouble speaking, confusion, vision change, loss of bladder or bowel control, or after a head, neck or back injury needs emergency care. Call 911 or go to an emergency room.

Keep taking prescribed medicine and ask your doctor or pharmacist. You can report a problem to the FDA (FDA, How to Report a Problem with Dietary Supplements). See the side effects guide.
What should you do before you order?

FAQ01
Questions about side effects
Can Nervecept upset your stomach?
It can. Boswellia and bromelain are both linked to stomach upset or diarrhea in the sources we cite. Take the capsule with an 8 oz glass of water, as the label says.
Does Nervecept interact with warfarin or aspirin?
It may. Glucosamine and chondroitin have been tied to more bleeding in people on warfarin, and turmeric may raise bleeding risk. Tell your prescriber about the bottle before you start.
What happens if you take Nervecept with a shellfish allergy?
The label states it contains shellfish (crayfish), so a reaction is possible. Ask your doctor first, and seek emergency care for swelling or trouble breathing.
