Experts Question Alkaline Water Benefits Above pH 9.8 as Risks Outweigh Temporary Relief
1 articles · Updated · Fox News · Jun 6
Summary
Experts said evidence for alkaline water’s health benefits remains weak, with any effect—such as brief heartburn relief—likely temporary rather than a meaningful long-term change.
Harvard Health’s Howard LeWine said stomach acid quickly overwhelms alkaline water and kidneys rapidly rebalance blood pH, limiting claims that it can neutralize body acidity.
Mayo Clinic flagged safety concerns when alkaline water exceeds pH 9.8, warning it may contribute to hyperkalemia; experts said risks may be higher for people with kidney disease or those taking PPIs.
Claims that alkaline water may help bone loss, acid reflux or GERD have appeared in some studies, but experts said more research is needed to confirm durable benefits.
Nutritionist Robin DeCicco said reducing acidity is better addressed through diet and reflux-management habits—real foods, less sugar and caffeine, not lying down after meals—and medical advice when symptoms persist.
