Nervala is a once-a-day nerve support capsule from Barton Nutrition. It has just two ingredients: 600 mg of alpha-lipoic acid and 75 mg of benfotiamine, a fat-soluble form of vitamin B1. Alpha-lipoic acid at this dose has been tested in people with diabetic nerve damage, with modest results. The benfotiamine dose is much lower than in most studies.
On the official sales page it costs $49 to $67 a bottle, depending on how many you order, with a 365-day money-back guarantee.

What is in Nervala
Barton Nutrition's own product page lists the amounts from the Supplement Facts panel. One serving is 1 capsule, and each bottle holds 30 servings (one month). The right-hand column is the seller's own wording.
| Ingredient | Amount per capsule | What the seller says |
|---|---|---|
| Alpha-lipoic acid (ALA) | 600 mg | An antioxidant that helps "neutralize free radicals" and support nerves |
| Benfotiamine (vitamin B1) | 75 mg | A fat-soluble B1 that "supports normal nerve signaling" |
The seller says to take one capsule with your first meal of the day. The page says there are no other added ingredients.
What the research says about the ingredients
Alpha-lipoic acid
Alpha-lipoic acid is the best-studied supplement for diabetic nerve pain, but most trials are short.
- SYDNEY 2 (2006): 181 people with diabetic nerve damage took 600, 1,200 or 1,800 mg of ALA by mouth, or a placebo, for 5 weeks. Symptom scores (stabbing pain, burning, pins and needles, numbness) fell by about half in the ALA groups and by about a third with placebo. Higher doses did not work better, but caused more nausea, vomiting and dizziness. The authors said 600 mg once a day gave the best balance of benefit and side effects.
- NATHAN 1 (2011): 460 people with mild to moderate diabetic nerve damage took 600 mg of ALA or a placebo for 4 years. The main measure (a combined score of nerve tests) did not differ between the groups. Some secondary nerve exam scores were better with ALA. Serious side effects were reported more often in the ALA group (38%) than with placebo (28%).
- A 2012 review pooled trials and found ALA lowered symptom scores. The authors said the clearest benefit was with ALA given through a vein for 3 weeks. They said it is unclear whether the gains seen after 3 to 5 weeks of ALA by mouth are big enough to matter in daily life.
So the 600 mg dose in Nervala matches the trials. But the effect of ALA pills was modest, and the long trial did not meet its main goal.
Benfotiamine
- BENDIP (2008): 165 people with diabetic nerve damage were assigned to 300 or 600 mg of benfotiamine a day, or a placebo, for 6 weeks. One symptom score improved, mostly in the higher dose group. A second symptom score did not change. The authors said more studies are needed.
- Fraser 2012: 67 people with type 1 diabetes took 300 mg a day or a placebo for 24 months. Vitamin B1 levels in the blood went up a lot, but there was no difference in nerve function.
Nervala has 75 mg per capsule. That is a quarter of the lowest dose in these trials. We did not find human trials of 75 mg benfotiamine for nerve symptoms to cite here.
The bigger picture
The National Institute of Diabetes and Digestive and Kidney Diseases (part of the NIH) says that diabetes experts have not made special recommendations about supplements for people with diabetes. It advises talking with your doctor before using supplements. The proven way to keep diabetic nerve damage from getting worse is to manage blood sugar, blood pressure and cholesterol.

Barton Nutrition also sells Nervala on its own store, with different prices and a different refund period. Check which page you are ordering from before you pay.
Refund policy
The ClickBank sales page offers a 365-day, 100% money-back guarantee. It says you can contact Barton's U.S. customer service at any point in that year for a refund. Barton's own store page lists a 90-day guarantee instead, and says shipping fees are not refunded. Keep your order email and write down which site you bought from.
Who should be careful
- People taking diabetes medicine or insulin. The seller itself says alpha-lipoic acid can mildly lower blood sugar, and asks you to talk with your doctor so your numbers can be watched.
- People on thyroid medicine, chemotherapy or blood thinners. The seller asks these groups to check with a doctor first.
- People who are pregnant or breastfeeding.
- Anyone with new numbness, weakness or a foot sore. Nerve symptoms can come from many causes, including low vitamin B12, thyroid problems, alcohol and some medicines. See a doctor first.
Our verdict
Nervala is one of the more open nerve supplements: two ingredients, with the doses published. The 600 mg of alpha-lipoic acid matches what researchers tested, though the benefit of ALA pills was modest and the 4-year trial missed its main goal. The 75 mg of benfotiamine is far below the studied doses. If you want to try it, ask your doctor first, especially if you take diabetes medicine, and keep the refund terms of the page you bought from in mind.
FAQ
What are the ingredients in Nervala?
Two: 600 mg of alpha-lipoic acid and 75 mg of benfotiamine (a form of vitamin B1) in each capsule, according to Barton Nutrition's product page.
Does Nervala work for neuropathy?
There are no published studies on Nervala itself. Its main ingredient, alpha-lipoic acid at 600 mg, lowered symptom scores in short trials of people with diabetic nerve damage, but a 4-year trial did not meet its main goal. Nervala is a supplement, not a treatment for neuropathy.
How much does Nervala cost?
On October 27, 2026 the ClickBank sales page listed $67 for one bottle, $59 a bottle for three ($177) and $49 a bottle for six ($294).
Does Nervala have a money-back guarantee?
Yes. The ClickBank sales page offers a 365-day guarantee. Barton's own store lists 90 days. Check the terms of the page you order from.
Can I take Nervala with metformin or insulin?
Ask your doctor first. The seller says alpha-lipoic acid can mildly lower blood sugar, so your doctor may want to watch your numbers.
