Elderberry Berry Extract
Also known as: Black elderberry, Elderberry, *Sambucus nigra*
Overview
Elderberry (*Sambucus nigra*) is a fruit-bearing shrub native to Europe and North America, commonly used as an herbal supplement. Rich in anthocyanins, flavonols, and various polyphenols, elderberry is primarily noted for its antiviral and anti-inflammatory properties. Traditionally, it has been utilized to treat respiratory infections such as the common cold and influenza. Its key characteristics include a high antioxidant content, primarily from anthocyanins, which are associated with multiple health benefits. Research maturity is moderate, with growing interest in its potential applications in respiratory health despite the need for more rigorous trials to confirm efficacy and safety.
Benefits
Elderberry is recognized for reducing the duration and severity of upper respiratory symptoms, particularly in cases of viral infections like influenza. Studies have recorded a significant mean effect size in alleviating these symptoms, though results can vary across different trials. Additionally, elderberry may provide antioxidant and anti-inflammatory effects that could support cardiovascular health. Generally safe for adults, specific evidence regarding its effects on special populations, such as children and pregnant women, remains limited.
How it works
Elderberry's mechanism of action involves the modulation of inflammatory cytokines and the exhibition of antiviral activity, primarily facilitated by its constituents, particularly anthocyanins like cyanidin 3-O-glucoside. These compounds interact with the immune system to reduce inflammation and may inhibit viral replication, enhancing the body's defense against infections.
Side effects
Elderberry is typically considered safe for short-term use, with the most common side effect being gastrointestinal upset, although this is rare. Uncommon allergic reactions have been reported, while rare side effects are not well-documented. There is a concern for potential interactions with diabetes medications due to blood sugar modulation. Raw or unripe elderberries contain toxic compounds and should be avoided. Pregnant or breastfeeding individuals should consult healthcare providers before use due to insufficient safety data in these populations.
Dosage
There is no well-established minimum effective dose for elderberry; however, typical dosage ranges from 500 mg to 1,000 mg per day. Optimal dosages can vary based on the specific product and the condition being treated, with caution advised for amounts exceeding 1,000 mg daily. Elderberry is most effective when taken at the onset of symptoms and can be consumed in various forms, including capsules, syrups, and teas. Bioavailability may improve when taken with food.
