Schizandra Berry Extract
Also known as: Schizandra Berry, Omija, Five-Flavor Berry, Schisandra chinensis
Overview
Schisandra chinensis, commonly known as Schizandra Berry or Omija, is a plant native to East Asia, prized for its berries. These berries possess a unique five-flavor profile: sweet, sour, salty, bitter, and umami. As an herbal supplement, Schizandra is traditionally used to enhance vitality, improve mental clarity, and support immune function. The berries are rich in lignans, such as schisandrin, as well as flavonoids and phenolic acids, which contribute to its potential health benefits. Research on Schizandra is ongoing, with studies exploring its antioxidant, anti-inflammatory, and adaptogenic properties. While some studies show promising effects, more rigorous trials are needed to confirm its efficacy and safety. It is available in various forms, including capsules and extracts.
Benefits
Schizandra chinensis has shown potential in improving glycemic control and enhancing antioxidant capacity, according to some studies. Research indicates that an Omija extract and soybean mixture improved glycemic control in type 2 diabetes models. While some studies suggest potential benefits in muscle strength and fatigue reduction, the evidence is mixed. Schizandra may be particularly beneficial for individuals with type 2 diabetes or those seeking antioxidant support. However, more research is needed to quantify the clinical significance and effect sizes of these benefits. Observed benefits typically manifest over several weeks of consistent supplementation.
How it works
Schisandra chinensis exerts its effects through multiple biological pathways. Its antioxidant activity helps combat oxidative stress, while it may also influence glucose metabolism, potentially by enhancing GLUT-4 expression. Schizandra interacts with various body systems, including the cardiovascular system, where it may improve endothelial function, and the immune system, where it may enhance immunity. Lignans like schisandrin target cellular pathways involved in inflammation and oxidative stress. The absorption and bioavailability of Schizandra may vary based on extraction methods and formulation.
Side effects
Schizandra chinensis is generally considered safe when used appropriately, but comprehensive safety data are still lacking. Common side effects are not well-documented, but potential gastrointestinal upset has been reported. Uncommon and rare side effects are largely unknown due to limited reporting. Schizandra may interact with blood thinners or diabetes medications due to its effects on glucose metabolism. It is contraindicated during pregnancy and breastfeeding due to insufficient safety data. Caution is advised for individuals with diabetes or those taking medications that affect blood sugar levels. It is important to consult with a healthcare provider before starting Schizandra supplementation, especially if you have pre-existing health conditions or are taking other medications.
Dosage
The minimum effective dose of Schizandra chinensis is not definitively established, but typical dosages range from 500 mg to several grams per day. Optimal dosage ranges are variable, and more research is needed to determine precise recommendations. The maximum safe dose is not well-defined, so caution is advised when exceeding typical supplement ranges. There are no specific timing recommendations, but taking it with meals may help reduce gastrointestinal upset. Common forms include capsules and extracts. Bioavailability may be influenced by the presence of other nutrients or the method of extraction. No specific cofactors are required for its use.
