What Nerve Fresh does – and what it is for
It adds five plant ingredients to your day: passionflower, marshmallow root, corydalis, prickly pear cactus and California poppy. The maker presents it as daily nerve support. As a dietary supplement, it is not intended to diagnose, treat or prevent any disease, and it cannot repair nerves.
Does it work for neuropathy?
There is no evidence that Nerve Fresh treats neuropathy. The maker's page makes strong claims about relieving nerve pain and targeting specific enzymes; we left those out because there is no published trial of the product to back them.
Neuropathy is a diagnosis, not a single condition. Diabetes is the most common cause, but low vitamin B12, thyroid problems, kidney disease, alcohol, some medicines and other conditions can cause it too. Finding the cause matters, because treating it is what protects the nerves.
What is known about the ingredients
Passionflower and California poppy have long traditional use for calm and rest, and passionflower has been studied for its calming effect. Corydalis is a traditional Asian herbal root that contains alkaloids with sedative properties. Marshmallow root is rich in mucilage, a soothing plant fiber, and prickly pear contains antioxidant plant compounds. These are findings about the ingredients – often in different forms and amounts – not about Nerve Fresh as a product.
When to see a doctor
See a doctor if you have numbness, tingling, burning or pain in your feet or hands, especially if it is new, spreading or getting worse; if you have diabetes and notice any change in feeling in your feet; or if you have weakness, balance problems or a wound that is slow to close. Get urgent care for sudden numbness or weakness, particularly on one side of the body.
How to take it
The label serving is 2 capsules a day; the maker suggests one in the morning and one before bed. Do not exceed it. Because some ingredients can cause drowsiness, see how it affects you before driving.
