Glisodin Superoxide Dismutase
Also known as: Gliadin-protected superoxide dismutase, GliSODin, GP-SOD, Superoxide Dismutase (SOD)
Overview
Superoxide Dismutase (SOD) is a naturally occurring antioxidant enzyme crucial for neutralizing harmful superoxide radicals, thereby reducing oxidative stress. GliSODin is a proprietary formulation of melon-derived SOD combined with gliadin, a wheat protein. This gliadin protection is vital as it shields the SOD enzyme from degradation in the digestive tract, significantly enhancing its oral bioavailability. The primary aim of GliSODin supplementation is to mitigate oxidative stress-related damage. It has shown particular promise in clinical applications for skin conditions like vitiligo, where oxidative stress plays a key role. While research is ongoing, some clinical trials, especially in dermatology, indicate its potential. GliSODin acts as a potent free radical scavenger, offering a targeted approach to antioxidant support.
Benefits
GliSODin offers significant benefits, particularly in conditions linked to oxidative stress. In a randomized, placebo-controlled trial involving 50 vitiligo patients, GliSODin combined with narrowband UVB (NB-UVB) phototherapy resulted in nearly 20% repigmentation after 24 weeks, a statistically significant improvement compared to the placebo group's ~9% repigmentation (p < 0.0001). This study also noted a significant improvement in quality of life scores (DLQI) for the GliSODin group. The effect size, approximately doubling the repigmentation rate, is considered clinically meaningful for vitiligo. Beyond vitiligo, GliSODin provides general antioxidant protection by reducing oxidative stress markers, suggesting potential benefits in other oxidative stress-related conditions, as supported by mechanistic and animal studies. These benefits are primarily observed in adults with non-segmental vitiligo, with improvements typically seen after 12 weeks and optimal results at 24 weeks, potentially extending up to 6 months or longer.
How it works
GliSODin functions by delivering orally bioavailable Superoxide Dismutase (SOD) to the body. SOD's primary mechanism involves catalyzing the dismutation of superoxide radicals (O2•−) into less reactive species, specifically oxygen and hydrogen peroxide. This process effectively neutralizes one of the most damaging free radicals, thereby reducing oxidative damage to cells and tissues. In the context of vitiligo, this protection is crucial for melanocytes, which are highly susceptible to oxidative stress-induced damage, a key factor in the disease's pathogenesis. By reducing superoxide levels, GliSODin indirectly modulates redox-sensitive signaling pathways. The gliadin component is critical for its efficacy, as it protects the SOD enzyme from enzymatic degradation in the gastrointestinal tract, ensuring its absorption and systemic antioxidant effects.
Side effects
GliSODin has demonstrated a favorable safety profile in clinical trials, generally being well tolerated with no serious adverse events reported. Common side effects were not observed above placebo levels, and any reported adverse events were mild and transient. Uncommon or rare side effects have not been documented in available studies. However, due to the presence of gliadin (a wheat protein) in its formulation, GliSODin is contraindicated for individuals with gluten intolerance or celiac disease. There are no significant drug interactions reported, but caution is always advised when combining supplements with medications. Safety in special populations such as pregnant or breastfeeding women has not been established, and consultation with a healthcare professional is recommended before use in these groups. Long-term safety studies up to two years have indicated good tolerance without reported side effects.
Dosage
For adults with non-segmental vitiligo, the recommended dosage of GliSODin is 1 gram per day for the initial 12 weeks, followed by a maintenance dose of 0.5 grams per day. This regimen was effectively used in randomized controlled trials. The optimal dosage ranges align with these clinical trial protocols, as no toxicity has been reported at these studied doses, and a maximum safe dose has not been definitively established. Timing considerations are important, especially when used in conjunction with other therapies; for instance, efficacy was observed when daily oral GliSODin was combined with twice-weekly NB-UVB phototherapy. The gliadin-protected formulation is essential for oral efficacy, as it prevents the enzymatic degradation of SOD in the gut, ensuring its absorption and bioavailability. No specific cofactors are identified as required for its action.
FAQs
Is GliSODin effective alone or only with phototherapy?
Clinical evidence primarily supports GliSODin's efficacy in combination with narrowband UVB (NB-UVB) phototherapy for vitiligo. Its standalone efficacy is less clear and requires further research.
Is GliSODin safe for long-term use?
Studies up to two years have reported good tolerance with no significant side effects, suggesting a favorable long-term safety profile for GliSODin.
Can individuals with gluten sensitivity or celiac disease take GliSODin?
No, GliSODin contains gliadin, a wheat protein. Therefore, it is not recommended for individuals with gluten intolerance or celiac disease.
When can I expect to see results from GliSODin?
Improvements in conditions like vitiligo are typically observed after approximately three months of consistent use, with optimal results often seen around six months.
Does GliSODin cure vitiligo?
While GliSODin, particularly when combined with phototherapy, can significantly aid in repigmentation for vitiligo patients, it is not considered a cure for the condition.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC8360035/ – This randomized, placebo-controlled trial investigated the efficacy and safety of oral gliadin-protected superoxide dismutase (GP-SOD) combined with narrowband UVB (NB-UVB) phototherapy in 50 adults with non-segmental vitiligo over 24 weeks. The study found that the GP-SOD group achieved nearly 20% repigmentation, significantly higher than the placebo group's ~9%, alongside improved quality of life scores and good safety. This high-quality RCT provides strong evidence for GP-SOD as an adjunct therapy in vitiligo.
