FAQ

Isodrip is precision-distilled deuterium-depleted water bottled in glass. Ordinary water contains about 150 parts per million of deuterium — a heavier form of hydrogen. We bring that number down to 85, 105 or 125 ppm using vacuum fractional distillation, then verify every batch by mass spectrometry.

No. Isodrip tastes the same as clean still water. Some long-term drinkers describe it as “softer,” but blind taste tests do not reliably separate DDW from clean spring water.

Replace your normal drinking water with Isodrip — about 1.5 to 2.5 litres per day depending on your size and activity. There is no benefit to drinking extra; consistency matters more than volume.

You can, but heating does not change the deuterium ratio, and the bottle is small for cooking. Most people use Isodrip for direct drinking and stick to tap water for soup.

Your body deuterium ratio gradually returns to baseline. Nothing dramatic. Isodrip is not a habit you have to maintain at risk.

Deuterium is a heavier form of hydrogen — a hydrogen atom with one extra neutron. In water it sits at roughly 150 ppm. The deuterium-depletion hypothesis is that lowering this concentration may give mitochondrial ATP synthase a small but measurable break. The research is encouraging and ongoing.

They are completely different. Hydrogen water has dissolved molecular hydrogen gas (H₂) added to it. Deuterium-depleted water has the deuterium isotope partially removed. Different products, different mechanisms.

No. Alkaline water and “structured” or “hexagonal” water are marketing categories with no agreed scientific definition. DDW is a specific isotopic composition that can be measured to the part-per-million on a mass spectrometer.

Most foundational DDW research has come from Dr. Gábor Somlyai and HYD LLC. in Hungary, starting with their 1993 FEBS Letters paper. Our blog and Science page link to several peer-reviewed studies. Always check the original journal article rather than headlines.

Daily (125 ppm) for the first 4–6 weeks if you are new to DDW. Plus (105 ppm) for ongoing regular intake. Pro (85 ppm) for structured 30-day reset windows alongside training or travel.

Plastic micro-fragments make it into bottled water more often than anyone is comfortable with. Glass is heavier and costlier to ship, but for a product whose whole pitch is purity, glass is the consistent choice.

Yes — subscribe and save 15% per case, with free shipping in India. Pause or cancel anytime. The subscription is monthly by default; you can switch to fortnightly or quarterly.

Yes — unopened cases within 14 days. Opened cases cannot be returned for hygiene reasons, but if you are unhappy with your order, write to us and we will find a way.

Yes, at cost. Glass is heavy so international freight is meaningful. We aggregate shipments where possible. Email hello@isodrip.com for an international quote.

Each bottle has a QR code. Scan it to see the Certificate of Analysis for your specific batch — production date, source water, distillation runs, verified ppm and microbial panel.

We do not have enough specific data to recommend Isodrip during pregnancy or breastfeeding. Please ask your doctor.

Children can drink DDW; the research suggests no harm at consumer ppm levels. That said, we do not market Isodrip to children. Please use your own judgment with your paediatrician.

Sealed and out of direct sunlight is enough. Glass is forgiving. Once opened, refrigerate and use within 30 days for best taste.

No clinically significant interactions have been reported in the published literature, but the dataset is small. If you are on prescription medication, mention DDW to your physician so they can include it in your overall plan.
