Hi there,

Thanks for your feedback.

On our product pages, as you note, we make it clear under the ingredients tab exactly how much methylene blue is in both Blue Cannatine and Just Blue (and very clearly show the rest of our ingredients as well). Although you are the first person in three years to give this feedback, we are always trying to do better so please let us know what suggestions you have and we’ll consider them!

We understand your concern about PEG. The type we use is completely non-absorbable and we use small amounts only. You can read all about why we use it here.
There are many different types of silica. We use a food-grade version that is completely safe as well which you can find in the vegetables in your refrigerator. You can read about it here.

And to your last common regarding MB and CO. MB is on the WHO list of essential medications to treat methemoglobinemia that occurs from carbon monoxide poisoning. You are, however, correct that VERY high doses of MB--at least 1mg/kg taken for a prolonged period of time or higher doses taken for shorter periods--can actually cause methemoglobinemia or a syndrome similar to CO poisoning.

Our dosing is health optimizing dosing of MB and comes nowhere near this dosing and there is absolutely no risk of the symptoms you describe.

The only side effects of our dosing are blue urine (benign) and, if you are taking an SSRI, a potential interaction causing serotonin syndrome (but even that risk is very low). You should also avoid our products if breastfeeding or pregnant or have a known history of G6PD deficiency.

We hope this answers your questions. Thanks for your honest and direct feedback!
