Not a verdict — a checklist. Work through these and you'll make a decision you can defend either way.
The single most important item. Tingling and numbness have causes, several treatable, several progressive. Get blood glucose, HbA1c, B12, folate and thyroid tested first. Full detail in get diagnosed first.
If it's diabetes, is your glucose controlled? If it's B12 deficiency, are you being treated properly? Those interventions do more than any supplement. A supplement on top of them is reasonable; instead of them isn't.
NerveCept's isn't publicly documented. Email and ask for the complete list with milligram amounts. This is standard due diligence, not an unreasonable request.
Add it to everything else you take and compare against the 100 mg/day upper limit. Why this matters.
ALA against 600 mg, benfotiamine against 150–300 mg. See the label guide.
Particularly diabetes medication, thyroid medication and blood thinners. Take the panel to your doctor or pharmacist.
The brand asks for 30–60 days. A 2 or 3-bottle order covers that. Six months is a large commitment to a formula whose panel you may only just have seen.
This matters more for nerve symptoms than almost anything else, because they fluctuate naturally. Better days and worse days happen regardless of what you take — which makes memory an unreliable judge in both directions.
Before day one, write down for a week: how many days you had symptoms, intensity out of 10, whether they disturbed sleep, and any balance issues.
Daily tracking amplifies normal fluctuation into false signal. Weekly averages are far more informative.
If you start the supplement, change your diet and begin exercising in the same week, you won't know what did what. Stagger changes if you can.
Inside the 60-day guarantee, and past the brand's 30-day minimum. Compare your written weekly averages against your baseline week.
Realistic: fewer symptomatic days, or lower average intensity, sustained across several weeks. Modest but real, and visible in your notes rather than your impression.
Unrealistic: symptoms disappearing, or nerve function being restored. Where genuine nerve damage exists, "repair" in supplement marketing means nutritional support, not regeneration.
If symptoms worsen on any supplement regimen, stop and speak to a doctor — and mention the B6 content specifically. Worsening is not "it's working, push through."
