FAQ

Neolight Waters is the parent manufacturing company behind two consumer brands — Isodrip (wellness D2C) and Deutra (clinical grade). We produce precision deuterium-depleted water for athletes, longevity practitioners, B2B brands and clinics worldwide. Every batch is verified by isotope-ratio mass spectrometry calibrated to V-SMOW2 standards.

Same chemistry, different audiences. Isodrip is the everyday wellness line for D2C. Deutra is clinical-grade for hospitals, oncology centres and integrative clinics — distributed under physician guidance only. Neolight Waters is the parent: it sells the premium athlete and longevity line direct, and runs bulk supply to other brands.

Our deuterium-depletion facility is in India, housing multi-stage vacuum fractional distillation columns, an in-house isotope-ratio mass-spectrometry lab, a food-grade bottling line and remineralisation suite.

We do not know. Customer reports cluster around sleep, HRV and morning recovery rather than raw output. We sell water, not a stopwatch promise. The honest framing: replace your daily drinking water with DDW for 60 days and track your own metrics.

The most common pattern across our customer base: a 4-week foundation at 105 ppm, a 4–6 week intensive at 65 ppm (often timed to a competition prep block), then maintenance at 105 ppm. These are patterns we observe, not prescriptions.

Customers commonly use Neolight alongside resistance training, zone-2 cardio, sauna, time-restricted eating, and standard supplementation (creatine, electrolytes, omega-3, magnesium). DDW does not interfere with any of these.

Bulk 25 ppm concentrate (5L, 25L, 200L drums), custom-fill finished water at any ppm 25–125 in any volume, and full white-label private-label production with your branding. Typical first-run MOQ is 5,000 bottles, lead time 4–6 weeks from artwork sign-off.

Volume- and ppm-tiered. Lower ppm requires more distillation passes and costs more per litre. We do not list prices publicly because the meaningful number depends on volume, ppm, packaging and destination. The quote form takes a minute and we reply within two business days.

Yes. We ship a 1L evaluation pack with a recent CoA for qualified B2B accounts. Use the supply quote form and indicate “evaluation sample.”

Every shipment carries a Certificate of Analysis. For qualified buyers under NDA, we provide the full documentation pack — equipment qualification summary, batch CoA template, production SOP overview, food-safety registration documents and third-party test results.

Yes. We use freight-grade boxes and have shipped to North America, Europe and the Gulf without breakage. Heavy water bottles in glass are not cheap to fly. We are working on closer-to-customer fulfilment in the EU and US over the next 12 months.

Sealed and out of direct sunlight is enough. Glass is forgiving. Once opened, refrigerate and use within 30 days. Bulk drums have separate handling instructions in the supply pack.

Bottled water in general is not great for the planet. Our partial answer is glass-first, India-made, freight-aggregated where possible, and a return-and-reuse pilot for cases ordered within India. We do not pretend this is solved.

±2 ppm batch accuracy. Every production batch is sampled at three points and analysed by isotope-ratio mass spectrometry, calibrated against international reference standards (V-SMOW2 and SLAP2). External cross-check samples are sent to a third-party lab quarterly.

Every bottle has a QR code that opens the Certificate of Analysis for that specific batch in your browser. Production date, raw water source, distillation runs, verified ppm, total dissolved solids, microbial panel and storage recommendations are all there.
