Berberis vulgaris
Barberries are small red berries derived from Berberis vulgaris. They are rich in the bioactive compound berberine, which has been extensively studied for its effects on blood glucose regulation, lipid metabolism, and inflammation.
In a longevity context, barberries are particularly relevant due to their impact on key metabolic pathways and cardiometabolic risk factors.
Almonds provide a unique combination of monounsaturated fats, fibre, vitamin E, magnesium, and polyphenols. Polyphenols are concentrated in the skin and contribute to antioxidant and potential prebiotic effects, while the combination of fat, fibre, and protein supports sustained energy and metabolic balance.
Berberine has been shown to significantly reduce fasting blood glucose and HbA1c in human trials.
Studies show reductions in LDL cholesterol, triglycerides, and total cholesterol.
Berberine improves insulin signalling and glucose uptake.
It has been shown to reduce inflammatory markers linked to metabolic disease.

Berberine significantly reduces HbA1c, fasting glucose, and lipid markers across multiple trials.
View study on PubMed →Barberries are a potent source of berberine, with strong human clinical evidence supporting their role in blood sugar regulation, lipid metabolism, and overall metabolic health. They represent one of the most clinically validated plant ingredients for improving cardiometabolic risk factors.
