Schizandrins
Also known as: Schizandrins, Schisandra lignans, Omija, Chinese magnolia vine
Overview
Schizandrins are a group of bioactive lignans extracted from the fruit of *Schisandra chinensis*, a plant traditionally utilized in Chinese medicine. Known for their antioxidant, anti-inflammatory, and potential anti-diabetic properties, schizandrins are primarily applied to enhance vitality and support cardiovascular and cognitive health. The research maturity level for schizandrins is moderate, with increasing interest in their pharmacological effects, despite variable evidence quality, including some high-quality studies alongside the necessity for more systematic reviews. Schizandrins are typically consumed through supplements derived from *Schisandra chinensis* fruit, often as an herbal extract in capsule or powder form.
Benefits
Evidence suggests that extracts containing schizandrins may facilitate a reduction in fasting plasma glucose (FPG) levels in patients with type 2 diabetes, though benefits attributed specifically to schizandrins remain less clear. Other potential benefits include enhancement of cardiovascular health and improvement in cognitive function, primarily based on traditional usage and animal studies. Specific populations that may benefit include individuals diagnosed with type 2 diabetes or those seeking antioxidant effects. The data on effect sizes and clinical significance are limited, with benefits potentially observable after several weeks of supplementation as demonstrated with *Schisandra chinensis* extracts.
How it works
Schizandrins likely exert their effects through antioxidant and anti-inflammatory pathways. They may influence glucose metabolism, interacting with the body's cardiovascular systems, although specific molecular targets for schizandrins have yet to be clearly identified. Current knowledge regarding their absorption and bioavailability is limited, which requires further investigation to understand their effectiveness better.
Side effects
Generally deemed safe when consumed in conjunction with *Schisandra chinensis* extracts, the long-term safety profile of schizandrins specifically is not well established. Common side effects are not well-documented, though potential gastrointestinal upset has been noted in some cases. It is advised to use caution in diabetic individuals due to possible hypoglycemic effects and interactions with diabetes medications. Pregnant and breastfeeding individuals should avoid schizandrins due to insufficient safety data. Additionally, special care is recommended for individuals with diabetes to monitor blood glucose levels while taking such extracts.
Dosage
While specific minimum effective doses for schizandrins have not been firmly established, typical supplementation involves *Schisandra chinensis* extracts, often dosed at around 500 mg per day. Maximum safe doses remain undetermined. There are no particular timing recommendations. Schizandrins are commonly administered in capsule or powder forms, and their absorption may be influenced by other compounds present in the extract. Specific cofactors that may enhance their efficacy have yet to be identified.
