Quiet Nerves Ingredients: The Six Named in the Formula

Quick answer

Quiet Nerves is made with six ingredients: magnesium glycinate, alpha lipoic acid, butcher's broom, L-carnitine, turmeric and coenzyme Q10.

The turmeric is a 95% curcuminoid extract. Each ingredient has its own human studies, and the brand does not print an amount for each one.

The formula

What ingredients are in Quiet Nerves?

Mineral

Magnesium glycinate: what is it, and does it help nerves?

Magnesium glycinate is magnesium bound to glycine, an amino acid. Its nerve research is the thinnest of the six.

Magnesium glycinate powder, ingredient photo
Magnesium powder. The brand does not say how much magnesium glycinate one capsule holds, or how much of that is magnesium itself.

What it is

Your body uses magnesium in muscles, nerves, bones and blood sugar control. Adults need 310 to 420 mg a day from all sources (NIH ODS, magnesium).

What human studies found

A study of 978 adults with type 2 diabetes linked low blood magnesium to weaker nerve signals, but no one took a supplement (Chu et al., 2016). A small 8-week trial of 300 mg magnesium citrate a day did not show a clear gain over placebo (Ranjbar Arani et al., 2026).

Safety notes

Supplement magnesium has an adult upper limit of 350 mg a day, and large doses often cause diarrhea.

Antioxidant

Alpha lipoic acid: what is it, and what doses did trials use?

Alpha lipoic acid, also called thioctic acid, is an antioxidant the body makes in small amounts. It is the best-studied of the six for diabetic nerve symptoms.

Alpha lipoic acid powder, ingredient photo
Alpha lipoic acid powder. Nerve trials measured it in hundreds of milligrams a day.

What human studies used and found

The SYDNEY 2 trial gave 181 people with diabetic nerve damage 600, 1,200 or 1,800 mg by mouth once a day for 5 weeks. All three doses cut symptom scores more than placebo, and 600 mg did as well as the higher doses (Ziegler et al., 2006).

A four-trial review found a clear benefit from ALA given by IV drip, but gains from ALA by mouth were of unclear value (Mijnhout et al., 2012).

Safety notes

Nausea, vomiting and dizziness rose with the higher doses in SYDNEY 2. With insulin or diabetes pills, ALA may push blood sugar too low (Linus Pauling Institute, lipoic acid), and case reports link it to a rare autoimmune cause of low blood sugar (Veltroni et al., 2018).

Botanical

Butcher's broom: why is a leg vein herb in a nerve formula?

The brand does not say, but butcher's broom (Ruscus aculeatus) most likely backs its circulation line. The root extract of this small shrub has been studied for leg veins, not nerves.

Butcher's broom plant, ingredient photo
Butcher's broom, a shrub native to Europe. Extracts come from the root, and the only trials found measured swollen, heavy legs.

What human studies used and found

In a 12-week trial of 148 women with chronic venous insufficiency, a Ruscus extract shrank lower leg volume and eased heavy, tired legs more than placebo (Vanscheidt et al., 2002). A pooled look at 31 trials of a combination product, with 150 mg Ruscus extract per capsule, found modest drops in leg pain, cramps and heaviness (Boyle et al., 2003).

Safety notes

Memorial Sloan Kettering advises people with diabetes not to take it, after a reported case of diabetic ketoacidosis (MSK, butcher's broom). That matters, since diabetes is the leading US cause of nerve damage (NINDS, peripheral neuropathy).

Amino acid derivative

L-carnitine: is it the same as the acetyl-L-carnitine in nerve trials?

No. The brand names L-carnitine, but the nerve trials used acetyl-L-carnitine, a related form, so their results cannot simply carry over.

L-carnitine powder, ingredient photo
L-carnitine powder. The brand names this plain form, not the acetyl form that the nerve trials used.

What it is

Carnitine helps carry fats into the parts of cells that burn them for energy. The body makes its own, and animal foods add more (NIH ODS, carnitine).

What human studies used and found

Two year-long trials gave 500 or 1,000 mg of acetyl-L-carnitine three times a day. The higher dose eased pain where pain was the main complaint and improved vibration sense, but nerve conduction did not change (Sima et al., 2005). Cochrane rated the evidence very uncertain (Rolim et al., 2019 (Cochrane)), and another review noted most trials were maker funded (Li et al., 2015).

Safety notes

Near 3 grams a day, carnitine can cause nausea, diarrhea and a fishy body odor.

Botanical

Turmeric at 95% curcuminoids: how does it differ from the curcumin in the nerve trial?

The info page says the turmeric is standardized to 95% curcuminoids, the root's yellow compounds. The one nerve trial found used nano-curcumin, a high-absorption form.

Turmeric root and powder, ingredient photo
Turmeric, the root behind the extract. A 95% standard describes how pure the extract is, not how much of it sits in each capsule.

What human studies used and found

In an 8-week trial, 80 people with type 2 diabetes took 80 mg of nano-curcumin or a placebo. The curcumin group ended with lower neuropathy scores and lower blood sugar (Asadi et al., 2019). No nerve trial of a standard 95% extract was found.

What it isRoot extract, mostly curcuminoidsTiny particles made to absorb better
In Quiet NervesYes, per the info pageNot stated
Nerve trials foundNoneOne small trial, 80 mg for 8 weeks

Safety notes

Federal experts find too little evidence that curcumin helps any condition, and note liver injury reports with high-absorption products (NCCIH, turmeric). Turmeric may also raise bleeding risk with warfarin or other blood thinners (MSK, turmeric).

Antioxidant

Coenzyme Q10: what did the one nerve trial find?

Coenzyme Q10, or ubiquinone, is an antioxidant your body makes and uses to produce energy in cells. One small trial has tested it in diabetic nerve damage.

Coenzyme Q10 powder, ingredient photo
Coenzyme Q10 powder. Studies of rare inherited energy disorders have used 600 to 3,000 mg a day safely (NIH ODS, mitochondrial disorders).

What human studies used and found

In that trial, 49 people with type 2 diabetes took 400 mg a day or a placebo for 12 weeks. Symptom scores and some nerve signal tests improved in the CoQ10 group, with no drug-related side effects (Hernandez-Ojeda et al., 2012). The summary mostly compares people with their own starting scores, not with placebo.

Safety notes

Side effects are usually mild, such as poor sleep or an upset stomach. CoQ10 may interact with warfarin and with insulin (NCCIH, coenzyme Q10).

Dose check

How much of each ingredient does Quiet Nerves contain?

Nobody outside the company knows. Every bar stays empty because no amount is published; each note gives the dose used in human studies.

Quiet Nerves label amountFull bar = dose used in human studies
Magnesium glycinate

Label: not published. Studied: no proven nerve dose; supplement upper limit 350 mg. (NIH ODS, magnesium)

Alpha lipoic acid

Label: not published. Studied: 600 mg a day by mouth (SYDNEY 2). (Ziegler et al., 2006)

Butcher's broom

Label: not published. Studied: studied for leg veins only. (Vanscheidt et al., 2002)

L-carnitine

Label: not published. Studied: trials used acetyl-L-carnitine, 1,500-3,000 mg. (Sima et al., 2005) (Rolim et al., 2019 (Cochrane))

Turmeric (curcuminoids)

Label: not published. Studied: 80 mg nano-curcumin (one small trial). (Asadi et al., 2019)

Coenzyme Q10

Label: not published. Studied: 400 mg a day (one small trial). (Hernandez-Ojeda et al., 2012)

Why the gap matters: Studied doses of alpha lipoic acid (600 mg) and acetyl-L-carnitine (1,500 mg or more) already pass 2 grams a day before the other four are counted. That is hard to fit in one capsule.

FAQ

Quiet Nerves ingredients FAQ

How many ingredients are in Quiet Nerves?

Six: magnesium glycinate, alpha lipoic acid, butcher's broom, L-carnitine, turmeric at 95% curcuminoids, and coenzyme Q10. Other ingredients are not published.

How much alpha lipoic acid is in Quiet Nerves?

Not published. In the SYDNEY 2 trial, 600 mg a day by mouth worked as well as higher doses.

Is the L-carnitine in Quiet Nerves the same as in nerve studies?

No. The nerve trials used acetyl-L-carnitine at 1,500 to 3,000 mg a day, a different form.

Does Quiet Nerves use nano-curcumin?

Nothing published says so. The info page describes turmeric at 95% curcuminoids, a standard extract, while the one nerve trial found used nano-curcumin.

Why does Quiet Nerves contain butcher's broom?

The brand does not say. Its research covers leg vein symptoms, which fits the circulation line. People with diabetes should read the safety note above first.

Has Quiet Nerves itself been tested in a study?

No study of the product or of this six-ingredient mix was found. Every result here comes from single-ingredient research.
