Metformin: To Do Or Not To DO

Metformin is a medication primarily used to treat type 2 diabetes. It works by reducing glucose production in the liver, increasing insulin sensitivity, and improving glucose uptake in peripheral tissues. However, over the years, Metformin has been found to have numerous benefits beyond treating diabetes. Let us examine the history of Metformin, its neurological, psychological and physical benefits, its use in bodybuilding and anti-aging movements.

History of Metformin

The history of Metformin dates back to the 1920s when it was first extracted from the plant Galega officinalis, commonly known as French lilac. It was initially used to treat diabetes in Europe during the 1950s. However, it was not until the 1990s that the drug gained popularity in the United States when it was approved by the Food and Drug Administration (FDA) for use in treating type 2 diabetes. Since then, it has become one of the most commonly prescribed drugs for the treatment of diabetes.

Neurological Benefits of Metformin

In recent years, researchers have begun to investigate the potential neurological benefits of Metformin. One study published in the journal "Brain Research" found that Metformin could improve memory and reduce cognitive impairment in mice (1). Another study published in the "Journal of Alzheimer's Disease" found that Metformin could reduce the risk of developing Alzheimer's disease (2). The researchers found that Metformin could reduce inflammation in the brain, which is thought to play a role in the development of Alzheimer's disease.

Psychological Benefits of Metformin

Metformin has also been found to have psychological benefits. One study published in the "Journal of Clinical Psychopharmacology" found that Metformin could improve symptoms of depression in people with type 2 diabetes (3). The study found that Metformin reduced symptoms of depression, anxiety, and overall psychological distress.

Physical Benefits of Metformin

Metformin is primarily used to treat type 2 diabetes, but it has also been found to have numerous physical benefits. One study published in the "Journal of the American Medical Association" found that Metformin could reduce the risk of cardiovascular disease in people with diabetes (4). The researchers found that Metformin reduced the risk of heart attack, stroke, and death from cardiovascular disease by 30%.
Metformin has also been found to have anti-cancer properties. One study published in the "Cancer Epidemiology, Biomarkers & Prevention" found that Metformin could reduce the risk of cancer in people with diabetes (5). The study found that Metformin reduced the risk of developing cancer by up to 25%.

Use of Metformin in Bodybuilding

Metformin has gained popularity in the bodybuilding community due to its ability to increase insulin sensitivity and improve glucose uptake in peripheral tissues. This can lead to improved muscle growth and recovery. One study published in the "Journal of Physiology" found that Metformin could improve muscle protein synthesis in healthy individuals (6).
However, it is important to note that the use of Metformin in bodybuilding is controversial and not recommended by healthcare professionals. Metformin is a prescription medication and should only be used under the guidance of a healthcare professional.

Use of Metformin in Anti-Aging

Metformin has gained popularity in the anti-aging community due to its potential to increase lifespan and reduce age-related diseases. One study published in the "Aging Cell" found that Metformin could increase the lifespan of mice (7). The researchers found that Metformin increased the activation of AMP-activated protein kinase (AMPK), which is thought to play a role in the aging process.
However, the use of Metformin in anti-aging is still an area of ongoing research and debate. While some studies have shown promising results, it is important to note that the effects of Metformin on human aging are not yet fully understood, and further research is needed to determine its safety and efficacy in this context.
