Nerve pain is a major problem that affects many people, particularly diabetics, many of whom suffer from pain in the peripheral nervous system. This pain can cause distress, anxiety, and stress, as well as getting in the way of your ability to work or perform regular daily activities.

Finding a supplement that can help relieve peripheral neuropathy pain and improve nerve health can make a huge difference to your quality of life, but it can be hard to tell which ones really work and are worth your time and money.

One of the new product options is Nerve Factor nerve supplement from Rejuvica Health, a liquid formula that promises all-natural ingredients and effective relief from pain. But is it worthwhile? Can you trust Rejuvica Health?

Let us take a look into the claims made by Rejuvica Health about their Nerve Factor product and see if this nerve supplement is as good as it looks. Whatever your questions about this product are, you can find the answer below in our Nerve Factor review!

What is Nerve Factor?

The biggest thing we need to deal with in our Nerve Factor review is the question of what this liquid nerve support supplement actually is. This is a peripheral neuropathy focused pain treatment made by Rejuvica Health, a united states based company founded in 2014.

It is important to note that none of the products made by Rejuvica Health come with certification from the food and drug administration (FDA), so there is no guarantee that their claims are accurate or that their product is even safe without careful research.

That being said, the company has been awarded a fairly solid A- rating by the Better Business Bureau and has a pretty good reputation in its home state of California.

Nerve Factor, made primarily from turmeric, b vitamins, and other herbal extracts, claims to relieve pain and improve blood flow in the body, helping to deal with the diabetic problem of numb feet.

Rejuvica say that this product contains all-natural ingredients and vitamins in its formula and that it offers advanced relief from pain and related symptoms.

Below, we will take a look at all of the claims and ingredients Nerve Factor presents and see if using nerve factor is likely to work to help with your pain and the health of your nerves in the rest of our review of the Nerve Factor product. 

Does Nerve Factor Really Work?

This is the big one: does the Nerve Factor product actually work to relieve nerve pain? Well, we've investigated reviews from customer review sites and scientific studies of all of the ingredients in this formula from Rejuvica to see if it is safe and effective for the customer to use or whether other supplements are a better bet.

Because Nerve Factor supplements come in a liquid form, they are easier to digest than supplements in capsule form. The various ingredients in this formula are brewed in a cool extraction method for 36 hours by Rejuvica, ensuring that none of the ingredients are denatured by high temperatures. 

This supplement should be taken twice a day, 1/4 teaspoon at a time, mixed either with water or taken straight, and it seems to work. Nerve pain is a complex field, but Rejuvica Nerve Factor seems relatively effective, thanks to its formula of folic acid, vitamin, and other ingredients chosen to support nerve health and blood flow.

Nerve Factor Ingredients 

This product contains a range of different ingredients, all of which contain valuable B vitamins and nutrients. The ingredients list for this formula is as follows:

Passion flower, Turmeric root, White willow bark, Skullcap herb, Feverfew Herb, Oat Straw Herb, and also purified water and vegetable glycerin for liquid.

The nutrients contained in this formula's ingredients include vitamin b1, vitamin b6, vitamin b12, folic acid, acetyl l carnitine, and alpha lipoic acid.

Of these ingredients, the most useful is probably turmeric, the ever-popular substance known for having a wide range of mild health benefits. It is not going to change your life, but turmeric is definitely good for blood flow and nerve pain, particularly in the blood circulation around your feet.

The high levels of vitamin b1, vitamin b6, vitamin b12, and other vitamins in this are good for nerve protection. Turmeric, b vitamins, and similar ingredients are common in supplements like this, and while they might not be massively effective, they certainly don't hurt.

The passion flower included here is a bit of an odd one. Passion flower is believed to help a little with a sense of relaxation and calm, but there is not much actual scientific research to back up the claims of neuropathy supplements using this ingredient. The alpha lipolic acid included in the formula is good for oxidative stress, helping to reduce stress-related pain. 

The other ingredients, such as feverfew herb, oat straw herb, white willow bark, skullcap herb, and acetyl l carnitine, don't have much evidence supporting their claimed benefits for pain relief, but they are common in neuropathy supplements and do not seem at all out of place in this formula.

It is mostly the B vitamins in this formula that are going to make a difference to your nerves, and the fact that it is a liquid is certainly not a bad one at all.

Nerve Factor Benefits

The Nerve Factor official website makes some big claims; the top of the Rejuvica website starts by asking, in big, bold text, "What's the big secret behind Nerve Factor's Liquid Formula?". The answer to this is a simple one: it's B vitamins. 

The high vitamin content of this liquid formula and its ingredients ensure that blood flow is quickly and efficiently boosted, reducing neuropathic damage to your feet and helping to deal with pain only a few minutes after use.

The big benefit of this liquid formula over other similar products is that Nerve Factor works faster on nerve pain than tablets and capsules of any similar product that you could use.

Nerve Factor Side Effects

There are no side effects listed for the Rejuvica Nerve Factor product online, and without Food and Drug Administration (FDA) approval, there is no way to know exactly what the risks of this product actually are.

We also don't know exactly how much of each ingredient, from alpha lipoic acid to passion flower, has been included in any single bottle of the product, which makes it hard to guess at the risk of side effects. Working from similar product options, such as Nervestra, we can make a pretty good guess at the possible side effects of this.

If the concentrations of the ingredients are too high, there is the risk of minor side effects such as dizziness or diarrhea, but that is as bad as it seems likely to be. There is no guarantee without FDA approval, but it seems likely that side effects are a minimal risk with this product. There is nothing more dangerous than alpha lipoic acid and turmeric included in this, and both of those are fine!

Nerve Factor Reviews & Complaints

There aren't many reviews of Nerve Factor online, and what there are seem relatively mixed. Customers generally feel that Nerve Factor doesn't do very much for their nerve pain, although it certainly isn't harmful.

As with many nerve pain medication choices, customers complain that Nerve Factor tastes terrible. There is not much to be done about that, and personal tastes will always vary.

Some customers find that Nerve Factor is a much more convenient treatment for nerve pain than most similar product options, and some of those say that it works well for them, particularly for nerve problems in the feet.

Overall, customer response has been very mixed, with no clear answer as to whether this is a good product or not.

Where to Buy Nerve Factor

This product is easy to buy from major storefronts like Amazon, as well as from the manufacturer's website. A single bottle of the Factor Nerve product comes in at $44, which is quite a lot, but the money-back guarantee means that you can try the product without any risk of being left out of pocket if it does not end up being very effective for you.

Should You Try Nerve Factor?

This product from Rejuvica might not be the best choice out there or the most effective, but it is not dangerous and should be at least vaguely helpful for most people. Because of the mixed response, we can't really recommend this product very highly, but we wouldn't go as far as to advise you to avoid it. It is not a bad choice at all, but it is not reliable and does not seem to make much difference to neuropathic problems for many users. As such, our recommendation here is a strong "maybe." It is expensive, and the results aren't great, but it is a legitimate option, and some people find it useful. 

What's the best nerve pain supplement?

Determining what the best nerve supplement for nerve pain is can be a difficult and frustrating problem. The issue is that everyone's body is different, and different people may get different results from the same neuropathy supplement product.

Reading customer reviews of products is an excellent way to start, but sometimes you just want to get a clear answer. While it is not as simple as identifying an objectively best neuropathy supplement for everyone, we can certainly give you a good starting point.

For our money, the best of the neuropathy supplements available at the moment is likely to be Nerve Renew by LifeRenew.
