Turmeric extract in Flow Nerves: what 95% curcuminoids tells you, and what it does not
Turmeric extract is one of the six ingredients Flow Nerves names, and the sales page describes it as 95% curcuminoids. That figure is a strength of the extract, not an amount per capsule, and no amount is printed. The one nerve trial we read found no difference. LiverTox reports liver injury cases, so ask a pharmacist first if you take a blood thinner.

What it is
What is turmeric extract in Flow Nerves?
Turmeric extract is one of the six named ingredients in the Flow Nerves capsule. The seller lists it inside a proprietary blend and prints no amount for it.
We hold no Supplement Facts panel, so we cannot say what the bottle prints. The sales page describes the extract as "95% curcuminoids" (Flow Nerves seller brief). Curcuminoids are the group of compounds in turmeric root that curcumin belongs to.
That percentage describes how concentrated the extract is. It does not say how much extract sits in one capsule. Ask the seller for a photo of the panel before you buy.
| Name as the seller lists it | Turmeric Extract, sales page: 95% curcuminoids (milligrams not printed) |
|---|---|
| What it is | An extract of the turmeric root standardized, per the sales page, to 95% curcuminoids; no amount is printed |
| What it is sold for | A named plant extract |
| Amount printed | amount not printed |
| Amount used in research | NCCIH; LiverTox; MSK; a curcumin bioavailability review; one 16-week nanocurcumin trial in 97 people with diabetic neuropathy |
| What the studies found | NCCIH says 'We don't know enough to definitively conclude if turmeric or curcumin is beneficial for any health purposes' and does not list neuropathy. A 2025 trial in Tehran gave 97 people with type 2 diabetes and diabetic peripheral neuropathy nanocurcumin 40 mg twice daily or placebo for 16 weeks and saw no significant difference in pain, the Neuropathy Disability Score or the screening exam; the authors say only one earlier randomized trial had looked at curcumin for this. A review says curcumin is poorly absorbed and lists piperine and other forms that raise absorption. The seller's 95% curcuminoids figure is a strength of the extract, not an amount per capsule. |
| Main caution | LiverTox rates turmeric likelihood score A as a cause of liver injury, with onset 1 to 4 months after starting and some cases reaching liver failure; NCCIH says to stop and call a provider for fatigue, dark urine or jaundice. MSK says people on warfarin or other blood thinners should not take turmeric supplements because of bleeding risk, and NCCIH says supplements may be unsafe in pregnancy. |
The 95% line
What do curcuminoids mean, and does 95% make it stronger?
A 95% curcuminoid extract is a concentrated form of turmeric. It does not tell you the dose, and it does not tell you how much your body absorbs.
A review of curcumin research reports that curcumin is poorly absorbed, and that piperine, liposomes or nanoparticles raise absorption (Anand 2007, curcumin bioavailability). We do not know whether Flow Nerves uses any of them, so we do not call the extract "enhanced" or "bioavailable".
What studies tested
Has turmeric or curcumin been tested for nerve symptoms?
Barely, and the one randomized trial we read found no difference. No trial tested Flow Nerves.
NCCIH says not enough is known to conclude that turmeric or curcumin is beneficial for any health purpose, and its page does not list neuropathy (NCCIH, Turmeric). A 2025 trial gave 97 people with type 2 diabetes and diabetic peripheral neuropathy nanocurcumin 40 mg twice a day or a placebo for 16 weeks. It found no significant difference in pain, the Neuropathy Disability Score or the screening exam (Mansour 2025, nanocurcumin neuropathy trial).
The people already had a diagnosed condition, the product was a nano formulation rather than a 95% extract, and the result was null. We read no trial for general nerve discomfort. The gauge below is an editor's reading of the human evidence, not a rating of Flow Nerves.
Magnesium
Little17 of 100
We found no human trial of magnesium glycinate for nerve symptoms; a Cochrane review found no clinically meaningful cramp benefit in older adults. (NIH ODS, Magnesium)
Alpha lipoic acid
Mixed36 of 100
Trials were in people already diagnosed with diabetic neuropathy at about 600 to 1,800 mg a day; the 4-year trial missed its main goal. (Hsieh 2023, oral alpha-lipoic acid meta)
Butcher's broom
Little17 of 100
The evidence is about leg swelling and heaviness from veins; we found no trial of butcher's broom for nerve symptoms. (Vanscheidt 2002, butcher's broom trial)
L-carnitine
Little17 of 100
The neuropathy trials used acetyl-L-carnitine at 1,500 to 3,000 mg a day, and the Cochrane review rates the certainty very low. (NIH ODS, Carnitine)
Turmeric
Little17 of 100
The one randomized trial we read (40 mg of nanocurcumin twice a day for 16 weeks) found no difference in pain or neuropathy scores; LiverTox rates turmeric 'A' for liver injury cases. (NCCIH, Turmeric)
Coenzyme Q10
Very little6 of 100
MSK mentions one placebo-controlled trial that suggested less pain in diabetic neuropathy; we read no trial of our own, and the statin-pain meta-analysis found no benefit. (MSK, Coenzyme Q10)
Our reading of the sources, not a measurement. Each needle is an editor's judgment of how well human studies support the nerve-support line for that ingredient, at studied amounts. It does not rate Flow Nerves: no study tested the capsule or this six-ingredient blend.
Liver
Can turmeric supplements affect the liver, and what about the gallbladder?
Yes, liver injury has been reported with turmeric supplements. LiverTox gives turmeric a likelihood score of A, its top category.
LiverTox says onset is typically 1 to 4 months after starting, daily doses in the reports ran from 100 to over 1,000 mg, and most people recovered within 1 to 3 months of stopping. Some cases reached liver failure, death or transplant. These are case reports, not a rate, and none involved Flow Nerves (LiverTox, Turmeric).
NCCIH says to stop and call a provider for fatigue, dark urine or jaundice (NCCIH, Turmeric). If you notice dark urine, yellow skin or eyes, belly pain or unusual tiredness, stop the capsule and get medical care the same day.
On the gallbladder, we found no source in our set on turmeric supplements and gallbladder disease. If you have liver or gallbladder disease, ask your clinician first.

Is turmeric a problem with blood thinners?
MSK says people taking warfarin or other blood thinners should not take turmeric supplements, because of bleeding risk (MSK, Turmeric).
We found no clinical trial of curcumin with antiplatelet drugs, so we cannot say how large the risk is. MSK also lists a chemotherapy caution. NCCIH's turmeric page does not name blood thinners, so we do not credit the point to it.
If you take a blood thinner, ask your prescriber or pharmacist before adding any turmeric product. Never stop or change a prescribed medicine because of a supplement. NCCIH says turmeric supplements in pregnancy may be unsafe, so pregnant or nursing readers should ask a physician first.
What is unknown
What do we not know about turmeric in Flow Nerves?
We do not know the amount, the form or whether the extract is absorbed well. No source answers those for this capsule.
- The amount per capsule: not printed in the material we were given.
- Any trial of this capsule or blend: none found.
- Any link between this capsule and liver injury: none reported in our sources, and none ruled out.
Persistent tingling, numbness or weakness needs a clinician who can look for a cause such as diabetes or a B12 shortage. A supplement does not find the cause.
Next steps
What should you ask a pharmacist about turmeric?
Bring a photo of the bottle and your medicine list, and ask three short questions: do I take a blood thinner, is my liver a concern, and what else am I taking.
Name every supplement, including magnesium and anything sold for nerves or circulation.
FAQ
Turmeric extract in Flow Nerves: common questions
Is there turmeric in Flow Nerves?
Yes. The seller names turmeric extract as one of six ingredients and describes it as 95% curcuminoids on the sales page. No amount is printed, and we hold no Supplement Facts panel, so the dose per capsule is unknown.
Does 95% curcuminoids mean the capsule is 95% curcumin?
No. The figure describes the extract, meaning how concentrated its active compounds are. It does not say how much extract the capsule holds. Without a printed amount, the 95% line cannot be turned into milligrams.
Can I take Flow Nerves with warfarin?
MSK says people taking warfarin or other blood thinners should not take turmeric supplements, and coenzyme Q10 has a warfarin report too. Ask your prescriber or pharmacist before taking Flow Nerves, and never change a prescribed medicine yourself.
Has turmeric been shown to help neuropathy?
We found no such result. One 2025 randomized trial of nanocurcumin in 97 people with diabetic neuropathy found no significant difference from placebo. NCCIH says not enough is known to conclude turmeric helps any health purpose.
Does Flow Nerves use a form of turmeric that absorbs better?
We do not know. The sales page says only 95% curcuminoids. A review reports curcumin is poorly absorbed unless paired with something like piperine, and the page names no such helper. We found no source on this capsule's absorption.
What are the signs of liver trouble from turmeric?
LiverTox and NCCIH point to fatigue, dark urine, yellow skin or eyes and belly pain. If you notice any, stop the capsule and get medical care the same day. Onset in the reports was usually 1 to 4 months after starting.
