What is Nerve Factor?
Nerve Factor is a natural supplement that is intended to increase nervous system comfort, reduce pain and tingling, and support long-term nervous system function. It comes in liquid form and there are about 48 servings in each bottle. The bottle also has a built-in dropper so you can administer the correct dosages.
The claims made by the manufacturer are left very vague. They mainly reinforce the idea that it is good for nervous system health and that it might help with common nerve pains. Multiple users have said that it helped alleviate tingling sensations in the extremities of the body.
Nerve Factor is a fairly popular nerve support supplement and it is even sold in some physical stores throughout the country. Some people seem to like it for its comfort-enhancing effects. Most people seem to use it in order to stop certain sensations that they believe to be caused by nerve damage.

How Does Nerve Factor Work?
Again, the manufacturers of this supplement remain very vague about how they think Nerve Factor will work in a practical sense. Most of their claims are about how they made the supplement and not what it will do. So to gain an understanding of how it might work, we need to look at the formula.
For instance, one of the main ingredients in the formula is skullcap. Skullcap is a flowering plant that has been used to treat a variety of psychological and nervous disorders.[1] When observed in clinical studies, skullcap has shown the ability to induce a feeling of calm and relaxation.
There is a dearth of hard clinical evidence that ties it directly with short or long-term nervous system health though. While ingredients like skullcap may hold benefits for cognition and psychological abnormalities, it may not directly influence the nervous system.
Nerve Factor Ingredients
Whole Passionflower Extract – Passionflower has long been used as a sort of natural sedative. Some studies show that passion flower has an effect on GABA production in the brain which may account for the natural “relaxing” effects of passionflower. According to the National Institutes of Health, it may also benefit neuropathic pain:
These findings suggest that Passiflora incarnata might be useful for treating neuropathic pain.[2] The antinociceptive and behavioural findings inferring that its activity may stem from underlying opioidergic and GABAergic mechanisms though a potential oleamide-sourced cannabimimetic involvement is also discussed.
Turmeric Root – Inflammation of the nerves has much the same effect as inflammation in other parts of the body: generally, it causes pain. The active compound in turmeric, curcumin, is a potent anti-inflammatory and some studies have found that turmeric suppresses glial activation and blocks pain signals in the spine.[3]
Thiamin – Thiamin is a form of vitamin B1 and there have been some studies that have identified thiamin deficiency as the potential cause of nervous system disorders. Specifically, studies have observed increased damage to nervous system signal receptors in conditions of thiamin deficiency.[4]
Alpha Lipoic Acid – Alpha lipoic acid may have analgesic effects on neuropathy caused by diabetic conditions. [5]Alpha lipoic acid is also an antioxidant so it may have nervous system-supporting benefits for the user. Still, it is unclear if ALA is useful for neuropathy not caused by diabetes.
Skullcap Herb – It has been claimed that,
The leaves of American Skullcap (Scutellaria lateriflora) are commonly used to address symptoms of neuropathy and nerve pain.[6]
Studies show American Skullcap has significant antioxidant effects, and may help protect against neurological disorders, such as Alzheimer’s disease, Parkinson’s disease, anxiety, and depression.
However, consumers need to be careful with skullcap as it may cause adverse interactions with other herbs and medications.

Minor Relief, Not Worth Price
Felt a tiny bit of comfort sometimes, but overall, Nerve Factor was costly for such limited relief. Tastes bad, and the benefits were inconsistent at best.
Pain Didn’t Really Improve Much
Used this for nervous system support, yet nerve pain and tingling barely changed. Results were so mild over the weeks that it was hard to tell if it did anything at all.
Unpleasant Taste Made It Hard
Tried Nerve Factor daily, but the taste was really unpleasant and made usage uncomfortable. Any reduction in tingling or nerve discomfort was subtle and not worth the struggle with the flavor.
