[Supplement Sleuth] 3 stars: Verified Active Potency on Lab Report, but 10x Dosing Error in Graphics
Methylene blue is a compound where verified USP Grade purity and accurate dosing guidance are essential. Evaluating this product against the third-party Certificate of Analysis (COA) uploaded to the listing images shows solid analytical testing alongside some glaring marketing and dosing contradictions.What the Lab Report ConfirmsAccredited Lab Assay: The published report from Progressive GMP Labs (Torrance, CA) matches Lot #251017-2B (Exp: 11/2027).Active Potency: The assay confirmed 4.62 mg of methylene blue and 10.7 mg of vitamin C per capsule (against a 5 mg / 10 mg target specification).Context for Dose: Around 4–5 mg per capsule is a commonly used low-dose range in nootropic products, so this result fits that general pattern.Why the Powder Is Off-White: The lab lists a total capsule fill weight of 0.2882 g (288.2 mg). The active methylene blue makes up only about 1.6% of the capsule content, which explains why the powder looks light/off-white rather than deep blue.The Major Dosing & Transparency Disconnects10x Math Discrepancy in the Graphics: The “Daily Protocol” infographic on this listing states that “1 capsule = 0.5 mg” and “2 capsules = 1 mg”, recommending users ramp up to “2–4 capsules daily.” However, the lab report for this lot shows each capsule actually contains about 4.62 mg. If a customer follows the 4-capsule recommendation thinking they are getting 2 mg total, they are actually closer to 18–20 mg based on this lab result. A 10x discrepancy on a potent compound is a non-trivial oversight.Copy-Paste Listing Errors: The protocol graphic includes a stray footnote stating “*At 4 drops per day dosage,” which looks like text copied over from a liquid product without the math being properly updated.Missing Heavy Metal Panel: While the listing header advertises the batch is “Verified Free Of Heavy Metals,” the 1-page report is strictly an active potency assay. It omits any ICP-MS screening data for lead, arsenic, cadmium, or mercury.Customer Support Blindspot: Direct outreach to customer support regarding batch records initially resulted in an “out of stock” answer, and they did not appear aware that a lab report for this exact lot was already posted in the Amazon image carousel.The ProsReal third-party lab testing from an accredited facility matching Lot #251017-2B.Confirmed 4.62 mg methylene blue and 10.7 mg vitamin C per capsule.Fill weight and potency that line up with typical low-dose nootropic usage ranges.The ConsSignificant 10x dosing conflict between the listing infographic (0.5 mg per capsule) and the lab assay for this lot (4.62 mg per capsule).Listing graphic includes apparent copy-paste leftovers from liquid products (“*At 4 drops per day”).Heavy metal and elemental impurity panel is missing from the published report, despite the “heavy metal free” banner.Customer support did not initially surface compliance documentation that was already on the listing.Verdict3 stars. The lab work confirms this is real methylene blue at a sensible low dose for my batch, and I give them full credit for posting a batch-matched COA directly to the listing. However, the listing’s protocol graphic quietly lowballs that dose by about 9 to 10x, and the prominent “heavy metal free” promise is not actually backed up by the potency-only COA they chose to show. This is not mystery powder, but it does require a careful buyer who is willing to double-check the math, read past the marketing, and verify the fine print.

Very good presentation
I really liked the presentation of this product. The bottle is well packed and the capsules are easy to incorporate into the daily routine. I also find it interesting that you combine methylene blue with vitamin C. The packaging indicates that it is USP grade and that it was tested by third parties, which gives me a good impression about the control of the product. The presentation is elegant and the bottle has a convenient amount. Overall, I am satisfied with the purchase and the quality of the presentation.

Methylene Blue in capsule form!
A USP 99.9% grade of Methylene Blue in an easily digested capsule, instead of the much harder to swallow, liquid dropper formula. 5mg per dose along with 10mg of Ascorbic Acid (Vit C). Of the many benefits touted, I do find an increased alertness and quicker recall of past events.

easy to take
I started taking these again because lately I’ve been forgetting things way too easily 😅, so I figured I’d give them another try and see if they help.So far, they haven’t bothered my stomach at all, which is a big plus for me. They’re easy to take and I haven’t noticed any weird aftertaste or anything like that.For the price, I think you get a pretty good amount. I also really liked the packaging. The box looks nice and feels like a good-quality product when you open it.I can’t really say yet if they’re helping with my memory because I just started taking them again, but so far, so good. I’ll keep taking them and see what happens. Hopefully my brain gets the memo! 😂

Nice product
I’ve been using the HEALTHLETIC Methylene Blue Capsules for about two weeks. As a college student and volleyball player, I have a pretty busy schedule with classes, practices, and games, so having something convenient that fits easily into my routine is important to me. I’ve noticed that I feel a little more focused and energized throughout the day, especially when I have a long day of classes followed by volleyball practice. I also really like the capsule form because it’s clean and easy to take compared with liquid methylene blue. The added vitamin C is also a nice bonus. Overall, these capsules have been a convenient addition to my daily routine, and I would definitely continue using them.

Solid Quality and Clean Formulation, Though Effects Were Milder Than Expected.
HEALTHLETIC’s USA‑made USP Grade Methylene Blue Capsules offer a high‑quality formulation with clear attention to purity and safety. The combination of 5mg pharmaceutical‑grade methylene blue and 10mg vitamin C is well‑constructed, and the product’s third‑party testing, formaldehyde‑free composition, and non‑GMO certification reinforce confidence in its manufacturing standards.From a usability standpoint, the capsules are easy to take and well‑tolerated, and the clean ingredient profile is a strong advantage for anyone prioritizing transparency and professional‑grade supplements. I did notice some cognitive and clarity‑related benefits, but the effects were not as pronounced as those I’ve experienced with another brand. While still effective, the overall impact felt more subtle and gradual.
