DMSO Supplements: Miracle Cure or Dangerous Distraction?

You may have heard the buzz about DMSO (dimethyl sulfoxide) as a "cure-all" supplement. People claim it treats everything from arthritis to cancer; but what does the science really say? Let's separate fact from fiction. 

‍

Current State of Knowledge: 

DMSO is an organosulfur compound with a long history of medical intrigue. It is a by-product of paper making and is found in wood (Saling). It was originally used as an organic solvent, but it has recently been gaining popularity for its supposed anti-inflammatory properties. A 2017 study found that while low levels of DMSO do not harm immune cells, higher concentrations reduce lymphocyte activation and inflammatory cytokine production, showing an anti-inflammatory effect in vitro (de Abreu Costa et al.). DMSO is FDA approved as a prescription medication for treating symptoms of bladder syndrome among a few other conditions (Saling). 

DMSO gets absorbed topically, meaning through your skin, which is often why it is found in a variety of creams, lotions, or ointments. DMSO was originally thought to treat osteoarthritis (OA), but a meta-analysis found that DMSO “are not clinically effective in the reduction of pain in the treatment of OA” (Brien et al.). Another study found that chronic low doses of DMSO improved memory, anxiety, and behavior in an Alzheimer’s mouse model (Penazzi et al.). However, human data is sparse.

‍

Methodological Insights: 

The DMSO literature is limited by small sample sizes, lack of blinding or controls, and publication bias toward positive findings. Many promising animal results have not been translated to humans. 

Additionally, DMSO is a "penetration enhancer" that helps other substances enter the body. This quality makes it hard to isolate DMSO's specific effects as it's often combined with other compounds, clouding interpretations (Marren).

‍

Three Viewpoints:

Mainstream Medical Perspective:

Rheumatologists and clinical researchers urge caution regarding DMSO’s therapeutic use beyond its approved role as a pharmaceutical penetration enhancer. It was shown that DMSO has no clear evidence in the treatment of osteoarthritis. Many healthcare professionals declare that further research must be done on DMSO to determine its safety and efficacy (Brien et al). 

DMSO is FDA approved to treat interstitial cystitis, which may be a course of treatment that healthcare professionals may recommend. Overall, DMSO research does not seem to support the claims regarding its “anti-inflammatory” properties, and many healthcare professionals may agree. If you are considering using DMSO, consult your healthcare provider to determine whether it is appropriate and safe for your individual needs.

Alternative / Holistic:
Some practitioners in integrative and naturopathic medicine view DMSO more favorably, citing its anti-inflammatory and analgesic properties as observed in preclinical studies. Early research and recent animal models suggest potential benefits, but even proponents acknowledge that dosing, purity, and administration are critical variables. It is important to note that although some promising results have come out of animal studies, they have not been translated into human studies and therefore its effectiveness in humans is unknown. 

Public and Social Media Perspective:
DMSO has gained renewed attention on social media, where athletes and fitness influencers frequently promote it for post-exercise soreness and injury recovery. However, science communicators and pharmacologists caution that personal testimonials are not evidence and that unsupervised use carries risks. 

‍

Synthesis: 

The controversy between DMSO supporters and skeptics involves anecdotal evidence versus scientific facts about the use of DMSO. Although there are interesting findings from studies on animals and patients, there has not been enough proof for it to be applicable for regular conditions.

Alternative health advocates argue this absence of evidence isn't evidence of absence. They lean on traditional use and patient experiences to support DMSO supplementation.

‍

Future Directions:

1. Conduct robust human trials of DMSO for inflammatory conditions like arthritis, using placebo controls and clinically relevant endpoints.
2. Explore optimal dosing, administration (oral vs. topical), and safety/toxicity profiles.
3. Investigate DMSO's mechanisms of action and synergy with other compounds.
4. Develop standardized, quality-controlled DMSO supplements to ensure purity and potency.
5. Educate the public on potential risks like skin irritation, garlic body odor, and contaminant concerns with industrial-grade DMSO.

‍

Closing Summary: 

Until well-designed human studies are conducted, DMSO supplements remain experimental, and anecdotal reports should not replace standard medical care. DMSO remains a puzzling paradox due to its tangible potential mixed with a frustrating lack of hard proof. While some dismiss it as an unsupported gimmick, others see an undervalued therapy deserving deeper study. As always, the truth likely lies in the nuanced middle.

‍

Credibility Rating: 3/10

• Scientific Evidence in Humans: 2/10 (few controlled trials, mixed results)
• Animal Model Strength: 5/10 (several positive studies, unclear translation to humans)
• Safety Profile: 4/10 (appears low risk but under-researched, contaminant concerns)
• Risk-Benefit Ratio: Unclear (potential benefits, but long-term risks unknown)
• Medical Consensus: Skeptical to neutral (most doctors advise against without more data)

LyfeiQ Score: 3/10 

The potential is intriguing, but the proof is lacking. Until better human studies emerge, approach DMSO supplements with healthy skepticism and medical supervision. Don't bet your health on anecdotes alone.
