Study, Trial or Testing Result Summary
Members OnlyHuman studies
This product is a vitamin B12 gummy sold for energy, and here it is being considered for occasional heartburn and acid indigestion relief. We were not given any human studies that test vitamin B12, or any other ingredient in this gummy, for heartburn, acid indigestion or fast relief of stomach upset. Because no studies were supplied, we cannot say whether it helps, does nothing or makes symptoms worse for this goal. The label we have is incomplete and lists only calories without amounts. The store listing names calories, total carbohydrate, vitamin B12 and sodium, and the product name gives 1000 micrograms of vitamin B12. There are no counted reviews and no written reviews could be read, so we know nothing about how members or other buyers have found it for heartburn. No experts on our panel commented on it. Until human studies on this goal appear, this product stays in the emerging group, and anyone with frequent or severe heartburn should look to options with direct evidence and speak with a health professional. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
Vitamin B12 is a smaller ingredient in this product, and the panel mostly speaks well of it: five of the ten latest positions are recommends, two are uses, two are neutral, and one is a warning. Panelists mainly take it for nerve health, brain function and mood, and energy, and several say to get tested and supplement if levels are low, with vegans singled out as most at risk. The form named most often is methylcobalamin, with one panelist preferring a liposomal and micellar version, one suggesting a under-the-tongue form for older people, and one aiming for a blood level around 500. For doses, one panelist takes 1 gram each morning, and for pairings, panelists mention vitamin B6, folate, and methylated folic acid. On caution, one panelist advises against it if your diet already covers your needs, one says to avoid it too close to bedtime, and one stopped taking it alongside fat burner injections and then had a rough emotional and hormonal period.
