The topic of methylene blue has been popping up in Toronto functional medicine and IV therapy circles. Sure, it sounds like a new shade of paint – but it actually has a key role in the history of conventional medicine!
Methylene blue (MB) has been studied in recent years for potentially supporting:
- Mental clarity and concentration
- Cellular energy (to reduce fatigue)
- Healthy aging
Scientists are intrigued by MB’s impact on brain function because the brain alone requires copious amounts of energy. That said, supporting energy production on a cellular level could theoretically (and positively!) affect cognition.
If you’re in pursuit of enhancing memory, reducing inflammation, or sustaining long-term wellness, you may be interested in this post! We introduce you to basic facts about methylene blue and how our IV Lounge can personalize this as an oral supplement or IV vitamin therapy.
Top 10 methylene blue quick facts
- It’s been embraced by Western medicine practitioners for over a hundred years. MB was the first synthetic remedy used in conventional medicine! The compound was used to treat malaria during the late 1800s. In the 1900s, it was also found to be therapeutic for cyanide poisoning.
- MB may support the ‘power plants’ of your cells. The mitochondria of your cells generate most of your cellular energy. Methylene blue has been shown to improve cellular respiration, helping to produce your body’s ‘energy currency’ called adenosine triphosphate (ATP).
- Small doses can potentially enhance cognitive clarity. When energy production is efficient, mental clarity and focus can be naturally reinforced. Human studies have shown that low MB doses may possibly enhance memory and brain activity, especially in regions that emphasize recall and attention skills.
- MB may promote antioxidant effects. Free radicals, which are unstable molecules that can cause cellular damage, can excessively accumulate in the body and trigger inflammation. Tailored methylene blue might be beneficial for stabilizing free radicals before they cause harm, making this therapy potentially helpful for managing some chronic conditions.
- It also contains antimicrobial properties. When activated by light, methylene blue has been shown to kill bacteria, viruses and fungi. It can also interact with the genetic material of microbes, damaging their DNA and preventing these germs from multiplying in the body.
- Adjusted doses might support mental health improvements. Getting methylene blue IV therapy or taking them as oral tablets may be impactful for mood and brain chemistry. Some studies suggest that MB bears influence over neurotransmitters, including serotonin and dopamine, especially since “…methylene blue has antidepressant, anxiolytic, and neuroprotective properties documented by both animal and human studies,” reports a CNS Drugs piece.
- It may be protective against neurodegeneration. Many brain diseases involve misfolded proteins. For example, in Alzheimer’s disease, certain proteins called tau proteins get tangled; and in Parkinson’s, there are clumps of misfolded proteins called alpha-synuclein. MB has the potential to interfere with protein clumping, helping to prevent toxic buildups. Think of it this way – methylene blue may be capable of preventing ‘protein junk’ from clogging your brain cells.
- Dosing significantly impacts health outcomes. The key to methylene blue’s effectiveness is dosing – this is due to the fact that it has a hormetic effect. This means that low doses can lead to beneficial effects, while high doses can lead to opposite effects. Hence, proper dosing and guidance from a healthcare practitioner are essential for relevance and safety.
Is this treatment right for you?
At the Toronto Functional Medicine Centre, methylene blue may be prescribed to qualifying patients as intravenous therapy or oral supplementation. To explore MB for your health and well-being, a qualified healthcare provider must assist you, such as one from our IV Lounge.
Personalized care must be considered for methylene blue administration, as your dosage must be customized. This means that an initial consultation is mandatory for getting a formal prescription – this session will involve a deep-dive into your personal health history, lifestyle and environmental factors, and current use of supplements and medications. We may explore other underlying concerns prior to prescribing MB, and functional lab testing may be advised for scrutinizing oxidative damage, cell health, inflammation, etc.
Note: Methylene blue is not recommended and will not be prescribed for pregnant and/or breastfeeding patients; those diagnosed with G6PD deficiency; people with severe kidney issues; and a known sensitivity to MB. If you’re currently on SSRIs, methylene blue is not advised because it can put you at risk for serotonin syndrome.
In perspective, MB is an example of how an older compound can find new life in our modern health needs. Its effects are wide-ranging – but also dependent on adapted dosing. Our clinicians can tailor several modalities for your health needs, from lifestyle modifications to tailored nutritional / botanical supplementation. Our functional naturopathic doctor is adept in pharmacognosy, so our wellness strategies take medication interactions, genetic profile, etc. into consideration.

Gain cognitive clarity, manage pain, and more at the Toronto Functional Medicine Centre
When was the last time you felt naturally energetic, free of pain, and confident in your long-term wellness needs? With functional medicine, the goal is to understand the root cause of health shortcomings. Knowing these can help you take actions toward optimal functioning. This involves applying a personalized approach to your health and well-being, tailoring therapies exclusively for your biology. Many patients who struggle with chronic illness opt into our functional medicine protocols for managing hot flashes, fatigue, insulin resistance, depression, weight gain, and more.
Our functional integrative wellness practices are comprehensive – we can responsibly mix and match Western and naturopathic medicine, various herbal medicines and hormone balancing strategies (i.e. bio-identical hormone therapy), and IV drip therapies. As we share space with the wellness hub Supernatural Yorkville, you also have access to their longevity tools, including cryotherapy, lymphatic drainage suits, red light therapy, and mediation frequencies. We aim to promote a therapeutic partnership between our clinicians and patients – every question you have is valid, and we provide you with lengthy sessions to help you understand your condition.
Our holistic care services also include functional lab testing, and some of the tests we offer cannot be accessed by some conventional medicine clinic. Our lab testing services are valuable for scrutinizing biomarkers linked to gut health, oxidative stress, metabolic detoxification, toxin exposures, cognitive decline, and more. These tests are necessary for customizing some modalities, such as IV therapy drips, oral supplements, and estrogen/testosterone therapy.
Currently, methylene blue can be prescribed and customized by our IV Lounge practitioners. Request your initial appointment now to reap the benefits of our holistic health modalities, IV vitamin therapy, and more from the Toronto Functional Medicine Centre.
