What is berberine?

Berberine is a natural plant product in the alkaloid group, compounds known for their significant physiological effects. High concentrations of berberine can be found in plants like goldenseal, European barberry, and Oregon grape. For over 400 years, this bioactive compound has been used in traditional Chinese medicine to treat various ailments, including infections, digestive complaints, and respiratory conditions.

In modern times, the benefits of berberine have been recognized in managing metabolic disorders. Despite its potential, it’s worth mentioning that the FDA does not regulate berberine for safety and effectiveness, and scientific evidence backing many of its claimed benefits remains insufficient.

Enhanced Absorption with Milk Thistle

Recent studies have shown that combining berberine with milk thistle can significantly enhance its absorption and bioavailability. Milk thistle contains a compound called silymarin, which has been found to improve the solubility and intestinal absorption of berberine. This synergistic effect allows for better efficacy at lower doses, potentially reducing the risk of side effects.

The scientific basis for this enhanced absorption lies in silymarin's ability to inhibit certain enzymes in the liver and intestines that typically metabolize berberine quickly, allowing more of the active compound to enter the bloodstream. Specifically, silymarin blocks the action of p-glycoprotein in the gut, a transporter protein that pumps foreign substances, including berberine, out of cells. By inhibiting p-glycoprotein, milk thistle reduces the expulsion of berberine from intestinal cells, thereby increasing its absorption and bioavailability.

This combination not only improves berberine's effectiveness but also offers additional liver-protective benefits, making it a popular choice for those looking to support both metabolic and liver health. Berberine with Milk Thistle by NMN Bio was formulated by a PhD holding scientist to ensure superior safety profile, and enhanced results. While regular Berberine are absorbed by 3% when taken orally, Berberine with Milk Thistle in granular form is being absorbed by 90%. What does this mean? Your sugar cravings are gone in 10 days or less.

How does berberine work?

Upon entering the bloodstream, berberine interacts with various cellular targets, enabling a wide range of effects. Additionally, berberine has been found to be effective in managing high blood pressure, especially when used in combination with other medications. Berberine helps regulate blood sugar levels and blood glucose by enhancing cellular response to insulin, which is especially beneficial for individuals with diabetes. This regulation occurs through its impact on lipid metabolism and insulin sensitivity, making it a powerful tool for managing both blood sugar and lipid levels.

The effects of berberine are comparable to certain medications, yet it remains a natural plant product. Berberine binds to different molecules within cells, influencing multiple pathways simultaneously and offering a holistic approach to managing various health conditions. Interestingly, Berberine with Milk Thistle had a superior blood sugar balancing effects in a human clinical trial, when compared side by side to Metformin, an FDA-approved drug for type II diabetes.

Insulin Sensitivity and Aging

Since nutrient sensitivity is one of the hallmarks of aging, so is insulin sensitivity. As we age, our body's ability to respond to insulin diminishes, leading to increased blood sugar levels and a higher risk of metabolic disorders such as type 2 diabetes. This decreased insulin sensitivity, or insulin resistance, can accelerate the aging process and contribute to the development of age-related diseases.

Berberine plays a crucial role in enhancing insulin sensitivity, making it an important longevity supplement. By improving the cellular response to insulin, berberine helps regulate blood sugar levels and maintain metabolic health. This regulation is achieved through its impact on lipid metabolism and insulin sensitivity, which are vital for aging individuals aiming to manage their blood sugar and lipid levels effectively.

Moreover, berberine's ability to activate AMP-activated protein kinase (AMPK) is another reason it is considered a valuable supplement for longevity. AMPK is an enzyme that plays a key role in energy balance and cellular metabolism. Activation of AMPK by berberine helps mimic the effects of calorie restriction, a well-known strategy for extending lifespan and promoting healthy aging.

In summary, berberine's impact on insulin sensitivity and its activation of AMPK make it a potent supplement for supporting longevity. By addressing the metabolic challenges associated with aging, berberine helps maintain overall health and well-being, making it a valuable addition to any longevity-focused regimen.
