Myo-inositol improves insulin resistance
The effect of myo-inositol supplementation on AMPK/PI3K/AKT pathway and insulin resistance in patients with NAFLD.
Significant findings for IR management
We conducted a double-blinded, placebo-controlled clinical trial to explore how myo-inositol (MI) influences insulin resistance (IR) among obese individuals with non-alcoholic fatty liver disease (NAFLD). Our study involved 48 participants who were randomly assigned to receive either 4 grams of MI or a placebo daily for eight weeks.

Throughout this period, we measured various parameters such as weight, serum glucose levels, and insulin sensitivity indices before and after the intervention. Notably, we found that MI supplementation led to significant improvements in the expression levels of key genes related to the AMPK/PI3K/AKT signaling pathway, which plays a crucial role in regulating metabolism.

The results indicated noteworthy enhancements in insulin resistance for those who received MI, measured through multiple indices, reinforcing its potential benefits for liver health management. Thus, we observed that supplementing with myo-inositol not only bolstered the expression of important metabolic genes but also helped improve insulin resistance in our participants with NAFLD.

Myo-Inositol shows promise for NAFLD
Does myo-inositol supplementation influence oxidative stress biomarkers in patients with non-alcoholic fatty liver disease?
Direct evaluation of inositol's effects
We aimed to explore the effects of myo-inositol (MI) supplementation on oxidative stress in obese patients suffering from non-alcoholic fatty liver disease (NAFLD). In our double-blinded, placebo-controlled study, 51 newly diagnosed patients were divided into two groups—one receiving 4 grams of MI daily and the other receiving a placebo—while following dietary recommendations for an 8-week period.

At the end of the trial, we observed that both groups experienced significant reductions in body weight and other obesity measures. Interestingly, those taking MI showed a slightly larger decrease in weight, which was statistically significant. While there was no significant difference in most antioxidant levels between the two groups, we noted that the MI group did see a greater reduction in serum nitric oxide.

Although both groups benefited in some ways—like a decrease in feelings of hunger and desire for unhealthy foods—the MI group specifically showed a more pronounced reduction in the desire to eat fatty foods. Overall, MI supplementation positively influenced weight and certain oxidative stress markers, while also providing potential advantages in managing dietary cravings. However, we did not find significant changes in many of the oxidative stress biomarkers related to liver function, emphasizing that while MI appears beneficial for some aspects, more research is needed to fully understand its effects on liver health.

Helpful symptoms improvement
Helpful for my disease symptoms. There is no flushing or itching, and as my doctor says, it significantly aids in alleviating my liver disease symptoms.

Unresolved liver toxicity
My hba1c rose from 5.5 to 6.3 (pre-diabetic) and my blood sugar spiked after taking this supplement, which made me feel nauseous and fatigued. This excessive dosage poses a danger regarding liver disease and needs a clear warning.

Cholesterol management
Niacin without flushing or itching! It's well-established for improving cardiovascular health without adverse effects like severe itching. I find it highly beneficial, and it's helped maintain my cholesterol levels over the years.

Cholesterol caution
After about 140 pills, I was diagnosed with suspected Brugada syndrome during a health check. Upon stopping the pills, my arrhythmia improved, yet my cholesterol remains high, and I fear my attempts to lower it may have harmed my liver health.

Cholesterol management
Excellent! Niacin reduces LDL cholesterol, enhances HDL cholesterol and lowers triglycerides. It may help prevent heart disease and treat type 1 diabetes. Niacin assists metabolism and is essential for immune function. The typical maintenance dose is between 1000-2000 mg daily.
