Our verdict in brief

Arialief is a once-daily nerve capsule whose core — palmitoylethanolamide (PEA, branded "Primepalm"), magnesium glycinate and alpha-lipoic acid — is the most evidence-adjacent formula in our nerve queue: PEA genuinely has small trials and meta-analyses showing modest neuropathic-pain relief at 600–1,200 mg/day, and ALA's 600 mg diabetic-neuropathy file is real. But the PEA amount hides inside the Primepalm trademark, no dose for anything is published, supporting ingredients differ between listings, the guarantee is advertised as both 60 and 180 days, and marketing claims "FDA clearance" — a status supplements cannot have. Evidence rating: 2.5/5. Product Fit Score: 3.1/5. Sudden or undiagnosed nerve symptoms still start at a doctor, not a checkout.

Evidence & product fit

Evidence Rating: 2.5/5

PEA has a genuine file — small trials and meta-analyses show modest neuropathic-pain reduction at 600–1,200 mg/day — and ALA's diabetic-neuropathy evidence is real at 600 mg; the score stops there because no dose is published, and trial-dose PEA doesn't fit a one-a-day capsule with room left over.

Product Fit Score: 3.1/5

This separate practical score is the equal-weight average of the five factors below. It does not increase the evidence rating and is not a customer rating.

Product Fit factorScore (out of 5)Why
Formula completeness2.0The active is wrapped in a proprietary name ("Primepalm") with its PEA content undisclosed; supporting ingredients vary between listings; guarantee advertised as both 60 and 180 days; and an "FDA clearance" claim appears on marketing pages — a status no dietary supplement has.
Ease of use4.5The capsule format is generally straightforward, but clear serving directions were not available in the product facts we verified.
Guarantee & buying terms3.060 days on the pages closest to official; screenshot yours.
Price / value2.0$49–79/bottle against generic PEA, magnesium glycinate and ALA sold openly at known doses for far less.
Category relevance4.2The named formula is broadly aligned with nerve support positioning. Category relevance measures fit to the intended use; it does not mean the finished product has been clinically proven effective.

Might suit you if…

  • Someone with diagnosed neuropathic pain whose prescriber has cleared a PEA trial — though an open-label PEA product at a stated 600–1,200 mg is the version of that experiment worth running
  • {'A magnesium angle': 'if cramps-with-tingling is your picture, glycinate is a reasonable form — also cheaper bought as itself'}

Skip it if…

  • Anyone buying because "FDA clearance" sounded official — no supplement has that; the claim itself is the tell
  • Undiagnosed tingling, burning or sciatica-like pain — cause first (glucose, B12, disc, entrapment), capsule later if ever
  • Anyone on blood thinners or diabetes medication without a prescriber conversation — ALA lowers glucose; turmeric (in some listings) interacts with anticoagulants

The Evidence Rating reflects research on the finished product and/or named ingredients for the intended use. The Product Fit Score is a separate practical assessment of formula completeness, ease of use, guarantee/buying terms, price/value and category relevance. Neither score is a customer rating, and affiliate relationships do not determine either score. See the full scoring method.

What Arialief is

Arialief is a one-a-day capsule from "Arialief Labs" (Aurora, Colorado listings) sold against neuropathy, sciatica and tingling at $49–79 per bottle depending on bundle, with a 60-day guarantee (some pages say 180 — FAQ). Label is web-sourced: the PEA + magnesium glycinate + ALA core converges across every listing; the supporting cast (butcher's broom, L-carnitine, turmeric, boswellia) varies by source; and no amounts are published anywhere — including by the affiliate page that claims the label "lists all dosages clearly" while listing none.

Why this one's different — and why it still can't score well

Our nerve reviews so far graded sedative herbs (Nerve Fresh) and an unidentifiable product (NerveCalm). Arialief's core is another species: PEA has actual randomized trials for neuropathic and sciatic pain (modest effects, 600–1,200 mg/day), ALA has the category's best-known file (600 mg, diabetic neuropathy), and magnesium glycinate is a defensible form of a nerve-relevant mineral. Ingredient selection: genuinely good.

The formula then does the one thing that makes good selection unverifiable — wraps its headline compound in a trademark ("Primepalm") with no stated PEA content, publishes no doses at all, and sells at a multiple of what the same three compounds cost open-label at known trial doses. Capsule arithmetic (FAQ) says the trial-range amounts don't fit anyway. Add the guarantee self-conflict and the impossible "FDA clearance" claim, and the pattern completes: this market's best formula idea, run through its standard machinery.

Verdict

2.4/5 — the highest score in our nerve set, for the ingredient thinking; every deduction is a concealment or a false regulatory claim. The reader who got this far wanting the actual experiment: diagnosis first, then open-label PEA at a stated 600–1,200 mg plus prescriber-screened ALA 600 mg — the same idea, checkable, usually cheaper, and refundable-by-not-needing-a-refund.

Frequently asked questions

Is PEA legitimate for nerve pain?

More than anything else in this aisle — palmitoylethanolamide is an endogenous fatty-acid amide with small randomized trials and meta-analyses showing modest neuropathic and sciatic pain reduction, typically at 600–1,200 mg daily over 3–8 weeks, with a benign side-effect profile. It's the rare funnel ingredient a pain clinician might actually discuss. Which is exactly why the dose matters and its concealment costs this product most of its score.

How much PEA does Arialief contain?

Not published — the PEA arrives as "Primepalm," a proprietary form whose content even sympathetic reviewers note isn't broken out on the label. For scale: trial-range PEA alone occupies most of a large capsule; a one-a-day capsule also fitting magnesium, ALA and botanicals arithmetically cannot hold it. Absent a stated amount, assume sub-trial.

Is the "FDA clearance" claim real?

No — and it can't be. Dietary supplements are not reviewed, approved or "cleared" by the FDA before sale; facilities register and follow manufacturing rules, which is a different thing every supplement shares. A seller converting facility registration into product "clearance" is teaching you how to read the rest of its page.

Which guarantee applies?

Pages nearest official state 60 days; others advertise 180 — the same conflict pattern as NerveCalm, our other nerve-funnel review. Score assumes 60. If purchasing, screenshot the terms at your checkout and keep the confirmation email; "no auto-renewal" claims are worth verifying on the card statement too.

Before you buy a nerve-health supplement

Numbness, burning, tingling or weakness can come from diabetes, vitamin deficiency, medication effects, nerve compression and other conditions that need a diagnosis. Supplements do not treat the underlying cause of neuropathy. New weakness, rapidly spreading numbness or loss of bladder/bowel control requires urgent assessment.
