Some markers improved; the most important one didn't. That mixed result is exactly why we show it. ## Why we read independent research first — and why you should too Most mainstream medical research is paid for by someone with a product to protect. When the funder profits from the result, the science bends — not usually through outright fraud, but through the quiet pressures of study design, selective publication and the way results are emphasised. Decades of meta-research confirm it: industry-funded trials reach favourable conclusions several times more often than independently funded ones. The cost of letting that bias run is not theoretical. Pain medicines once declared “safe” helped drive an overdose crisis that has killed hundreds of thousands. A blockbuster arthritis drug stayed on the shelves for years after its manufacturer saw the heart-attack signal mounting. Real products, real profits, real harm — documented in court records, not guessed at. - **Small independent labs have no ioniser, pill or patent to defend.** Their incentive is to find the truth and publish it — not to please a shareholder. - **The studies above come from exactly that kind of lab.** We have labelled each one's size and type honestly, included the disappointments, and linked every source. - **Read preliminary work as preliminary.** An honest pilot study is not a sales pitch — and a sales pitch dressed up as science is not a study. This is water, not medicine. We believe in honest inquiry pursued in good conscience: follow the evidence — and follow who paid for it. It would be easy to only tell you about the studies with tidy, positive results. We'd rather show you the messy ones — because that's how honest science looks. This 2008 randomised trial in *Nutrition Research* is a good example. ## What the study did In a randomised, placebo-controlled crossover design, 30 people with type-2 diabetes or impaired glucose tolerance drank about 900 mL of hydrogen-rich water per day for eight weeks, then switched. Researchers tracked blood lipids, oxidative-stress markers and glucose control. ## What they found Several markers moved in a favourable direction — for example, LDL ("bad") cholesterol and some measures of oxidative stress. But the headline long-term blood-sugar marker, **HbA1c, did not change significantly**. In the subgroup with impaired glucose tolerance, glucose tolerance appeared to normalise in a few people — an interesting but small finding. > Some improvements, no change in the marker that matters most, in a small and short study. That's a genuinely mixed result, not a win. ## The honest take We include this study precisely because it is not a slam-dunk. It hints that hydrogen might influence some metabolic markers, and it equally shows that the effect — if real — is modest and unproven. It is not a treatment for diabetes or any other condition; there are no authorised EU health claims here, and anyone managing blood sugar should follow their doctor, not a water machine. ## References 1.
