Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurobiological condition with onset in childhood. The disorder is characterized by inattention, impulsivity, and/or motor hyperactivity, which often affect the development and social integration of affected subjects. Phenylethylamine (PEA), naturally contained in the Klamath Lake microalgae and concentrated in the Klamin® extract, is an endogenous molecule with a general neuromodulatory activity. It functions as an activator for the neurotransmission of dopamine and other catecholamines, and very low concentrations of PEA may be associated with specific psychological disorders such as ADHD. The aim of our study was to evaluate the efficacy of the Klamin extract in treating a group of subjects diagnosed with ADHD. Thirty subjects, aged 6–15, who had been diagnosed with ADHD according to the DSM-IV TR criteria, were enrolled. The supplement was administered to all the subjects, who reported to an ADHD clinic for routine follow-up visits. Observations were made and data collected over a 6-month period. After 6 months of therapy the subjects appeared to show significant improvements based on assessments of their overall functioning, behavioral aspects related to inattention and hyperactivity–impulsivity, attention functions in both the selective and sustained component and executive functions. The study appears to confirm the initial hypothesis that the Klamin extract may positively affect the expression of ADHD symptoms. Additional larger studies on the effects of Klamin on ADHD are needed to further investigate the potential of this extract in ADHD treatment.

The aim of this study was to analyze the efficacy of berberine taken alone or in other formulations (with silymarin or other mixtures) on dyslipidemia through a systematic review of the literature and a meta-analysis. A systematic investigation was conducted on 19 studies that were selected based on inclusion and exclusion criteria. Both controlled trials (n = 12) and cross-sectional trials (n = 7) were included. The following formulations were examined: berberine used alone (n = 5), berberine combined with silymarin (n = 8), and other mixture containing berberine (n = 6). A meta-analysis was performed using a fixed-effects model and meta-regression. Total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides were considered. Moreover, possible associations of each parameter with age and the dose and duration of the treatment were analyzed. The data obtained showed a significant reduction in TC and LDL cholesterol for each formulation. A reduction in triglycerides was also observed for both TC and LDL but with a smaller impact. As regards HDL, a slight increase was observed, but it was not statistically significant. The formulation of berberine in association with silymarin was found to have the greatest impact on TC, LDL, HDL, and triglycerides. The greater efficacy of the formulation consisting of berberine associated with silymarin can probably be accounted for by the fact that the latter increases the bioavailability of berberine. However, it is necessary to carry out further clinical studies to better define the efficacy of the treatment and which patients show the best response.
