How to choose without getting burned
1. Ask for the test report
A Certificate of Analysis is a lab report for a specific batch. Look for the lab's name, the test method, the batch number and a purity figure. If a seller dodges the question, move on.
2. Know the format
Drops and capsules are pre-measured. Powder needs a precise scale and careful handling, and it stains heavily. We do not give preparation or dosing advice.
3. Check your medicines
Methylene blue can interact with some antidepressants and other medicines. The FDA has warned about this, so speak to a doctor or pharmacist before you try it.
4. Count the shipping
Sanare Lab and BP Life ship free over a minimum order, and CZTL does not state a cost. Outside the US, CZTL is the only one of the three that lists shipping abroad.
Common questions
Is methylene blue FDA-approved?
An injectable form is FDA-approved to treat a blood condition called methemoglobinemia, given under medical supervision. The FDA has not approved the drops, capsules or powders sold online.
Can methylene blue interact with other medicines?
Yes. The FDA has warned that methylene blue can cause a dangerous reaction with some antidepressants. Ask a doctor or pharmacist before use.
Which supplier is cheapest?
BP Life has the lowest-priced item, a $12.99 balm, and its drops are $29.97. Sanare Lab is $29.99 for drops or capsules. CZTL starts at $30 for 1 g of powder. The formats differ, so compare what you actually need.
Are these products tested?
Each company says so in its own way, and we have not run tests. Ask for the certificate for the batch you are buying.
How We Compare Methylene Blue Suppliers
Methylene blue suppliers sell very different things. One store offers liquid drops, another sells capsules, and a third sells bulk powder. Because the formats differ, we compare methylene blue suppliers on what each company says about testing, labelling, price and shipping, and not on a single price per gram.
Here is what we look at for each of the methylene blue suppliers on this page:
- Test reports. Does the store publish a Certificate of Analysis for each batch, or only say that products are tested?
- Labelling. Is the product described as USP grade, and does the store say what it is intended for?
- Company details. A real address and a way to contact the company are signs of a business that expects questions.
- Shipping. Free-shipping thresholds and the countries a store ships to change the real cost of an order.
- Stock. Sizes that show as sold out cannot be ordered, so we note them.
Safety points about methylene blue
The FDA has not approved methylene blue drops, capsules or powders sold online, and the medicine can interact with some antidepressants. That is why every one of our methylene blue suppliers pages carries a reminder to speak to a doctor or pharmacist first. We do not give dosing or preparation advice.
