Quick Answer
A methylene blue dosage chart is really just two pieces of label math laid out where you can see them: how many milligrams of USP-grade methylene blue are in each Nutricel product, and how that concentration converts to drops for the 1% liquid solution. This page puts both in scannable tables, plus a reverse mg-to-drops lookup and conversions for other common concentrations.
- Capsule mg is fixed and label-stated. Blue Boost 12 mg, Blue Immune 6 mg, Blue Renew 7 mg per capsule, Blue Shroom 7 mg, Blue Remove 18 mg, all verified on the live product pages.
- The liquid is a 1% solution, or 10 mg per mL. Using the standard 20 drops per mL dropper convention, one drop is approximately 0.5 mg. A 2% solution doubles that to roughly 1 mg per drop.
- This is unit-conversion, not a personal dosing recommendation. There is no bodyweight-based amount on this page. Follow the product label's Suggested Use section and talk to your healthcare provider about how much fits you.
Important: Methylene blue has documented interactions with serotonergic medications including SSRIs and MAOIs. Review the full adverse medications list before use.

Methylene Blue mg Chart by Nutricel Product
Every Nutricel capsule has a fixed milligram amount of USP-grade methylene blue printed on its Supplement Facts panel. That number does not change no matter how many capsules a label recommends, so it is the most reliable reference point for comparing products. The table below was verified directly against each live product page.
| Product | mg per capsule | Label serving size | Total mg per label serving | Approx. liquid equivalent |
|---|---|---|---|---|
| Blue Boost | 12 mg | 1 capsule | 12 mg per capsule | ~24 drops of the 1% liquid |
| Blue Immune | 6 mg | Varies -- see product label | 6 mg per capsule | ~12 drops of the 1% liquid |
| Blue Renew | 7 mg | 2 capsules | 14 mg (2 capsules x 7 mg) | ~28 drops of the 1% liquid |
| Blue Shroom | 7 mg | Varies -- see product label | 7 mg per capsule | ~14 drops of the 1% liquid |
| Blue Remove | 18 mg | Varies -- see product label | 18 mg per capsule | ~36 drops of the 1% liquid |
| Blue Liquid (1% solution) | 10 mg per mL | Measured with dropper -- amount set by you/your provider | Varies by amount used | 20 drops = 1 mL = 10 mg |
Three products (Blue Immune, Blue Shroom, Blue Remove) do not list a single fixed capsule count per serving on their label; Nutricel directs individual serving needs to a healthcare provider for those products. The mg-per-capsule figure itself is still fixed and verified regardless of how many capsules you are advised to take.
Drops to Milligrams: The 1% Liquid Conversion Chart
A 1% solution means 1 gram of methylene blue dissolved in every 100 mL of solution, which works out to 10 mg per mL. That part is simple percentage math. The part that actually answers "how many drops" is the dropper itself.
Pharmacy references define a standard medicinal dropper, per the convention shared by the United States Pharmacopeia, British Pharmacopoeia, and European Pharmacopoeia, as delivering 1 mL of an aqueous solution in about 20 drops. That puts one drop at roughly 0.05 mL. Multiply that by the liquid's 10 mg per mL strength and one drop works out to approximately 0.5 mg of methylene blue.
| Drops | Approx. volume | Approx. mg |
|---|---|---|
| 1 drops | ~0.05 mL | ~0.5 mg |
| 5 drops | ~0.25 mL | ~2.5 mg |
| 10 drops | ~0.5 mL | ~5 mg |
| 15 drops | ~0.75 mL | ~7.5 mg |
| 20 drops | ~1 mL | ~10 mg |
| 24 drops | ~1.2 mL | ~12 mg (matches one Blue Boost capsule) |
| 30 drops | ~1.5 mL | ~15 mg |
| 36 drops | ~1.8 mL | ~18 mg (matches one Blue Remove capsule) |
| 40 drops | ~2 mL | ~20 mg |
Why this is an approximation: a drop is a practical unit, not a lab-exact one. Actual drop size depends on the dropper tip, the liquid's viscosity and surface tension, and temperature, so treat every mg figure above as approximate rather than precise. This is also why the amount you personally use should be measured consistently with the same dropper each time.
Reverse Lookup: Target mg to Drops
The chart above starts from drops and works out to mg. This one runs the other direction: if you already know a target milligram amount, whether that is a round number or the exact figure on one of Nutricel's capsule labels, here is the drop count that matches it on a 1% solution.
| Target mg | Approx. Drops (1% Solution) | Matches |
|---|---|---|
| 1 mg | ~2 drops | - |
| 2.5 mg | ~5 drops | - |
| 5 mg | ~10 drops | - |
| 6 mg | ~12 drops | Blue Immune (1 capsule) |
| 7 mg | ~14 drops | Blue Shroom (1 capsule) |
| 10 mg | ~20 drops | - |
| 12 mg | ~24 drops | Blue Boost (1 capsule) |
| 14 mg | ~28 drops | Blue Renew (2-capsule serving) |
| 18 mg | ~36 drops | Blue Remove (1 capsule) |
Same approximation caveats apply here as above: real drop volume depends on dropper, viscosity, and temperature, so treat these as close estimates for comparison, not lab-exact figures.
If Your Liquid Is a Different Concentration
Every chart above assumes a 1% solution, which is what Nutricel's Blue Liquid is. Not every methylene blue product sold anywhere uses 1%, and 0.5% and 2% solutions both show up on the market. They look identical in the bottle. Only the label tells you which one you have, and that percentage directly changes how much a single drop delivers.
| Concentration | mg per mL | Approx. mg per Drop | Drops for ~10 mg |
|---|---|---|---|
| 0.5% | 5 mg/mL | ~0.25 mg | ~40 drops |
| 1% (Nutricel Blue Liquid) | 10 mg/mL | ~0.5 mg | ~20 drops |
| 2% | 20 mg/mL | ~1 mg | ~10 drops |
The same drop count is not the same dose across products. 10 drops from a 2% solution delivers roughly the same amount as 20 drops from a 1% solution. Always check the concentration printed on your specific bottle before applying any of the charts on this page, and never assume two bottles are equivalent just because the drop count looks familiar.
How to Read the Math on Your Label
People searching for a "methylene blue dosage chart by weight" are usually looking for a table that tells them how much to take based on how much they weigh. Nutricel is not going to build that table, and it is worth explaining why: adjusting a supplement amount for body weight is a clinical judgment call, one that depends on your health history, any medications you take, and goals only a healthcare provider can weigh together. A chart cannot make that call safely, and neither can a blog post.
What a chart can do reliably is unit conversion, and that is what the tables above are. The mg-per-capsule figures do not shift based on your body size; a Blue Boost capsule is 12 mg whether you weigh 130 pounds or 230 pounds. The liquid's 0.5 mg-per-drop conversion does not shift either, as long as you have confirmed the concentration on your specific bottle. Those numbers are fixed chemistry and fixed math. The only variable that should be personalized is how much you use, and that decision belongs with the Suggested Use section on the product label and a conversation with your healthcare provider, not with a formula tied to bodyweight.
For a walkthrough of how people commonly think about starting low and adjusting slowly with the liquid format, see Nutricel's methylene blue drops dosing guide. That article covers the reasoning; this page is the reference chart to come back to once you know the math.
Who This Is Not For
Do not take methylene blue in any form, at any dose, if you are currently using:
- SSRIs, SNRIs, MAOIs, or any other serotonergic medication (risk of serotonin syndrome)
- Known G6PD deficiency
- Pregnancy or nursing, without your healthcare provider's guidance
Review the full adverse medications list and Nutricel's methylene blue drug interactions guide, and consult your healthcare provider before starting methylene blue in any form or amount.
The Bottom Line
The numbers behind a methylene blue dosage chart are simpler than they look once you separate fixed chemistry from personal decisions.
- Every Nutricel capsule's mg amount is fixed and verified against the live product label: Blue Boost 12 mg, Blue Immune 6 mg, Blue Renew 7 mg per capsule, Blue Shroom 7 mg, Blue Remove 18 mg.
- The 1% liquid solution is 10 mg per mL, and a standard 20 drops-per-mL dropper puts one drop at roughly 0.5 mg. A 2% solution doubles that; a 0.5% solution halves it.
- Drop-based mg figures are approximate, since drop size varies slightly with the dropper, the liquid, and temperature.
- There is no bodyweight-based dosing chart here on purpose. That decision belongs with your healthcare provider, not a formula.
- Always follow the Suggested Use section on the product you bought, confirm the labeled concentration before converting drops, and review the adverse medications list before starting.
