Black Currant Fruit
Also known as: Ribes nigrum, Blackcurrant, Black Currant
Overview
Blackcurrant (*Ribes nigrum*) is a fruit known for its high anthocyanin content, including delphinidin and cyanidin. It is used in dietary supplements for its antioxidant and anti-inflammatory properties. Research suggests potential benefits for exercise performance and overall health, but the evidence quality varies. Blackcurrant extracts are available in various forms, including capsules and powders. The fruit is a rich source of vitamins and minerals, contributing to its potential health benefits. While generally considered safe, further research is needed to fully understand its effects and optimal usage.
Benefits
Blackcurrant extract may enhance exercise performance by improving cardiovascular function and reducing oxidative stress, although results vary across studies. Benefits may be more pronounced in athletes or individuals engaging in high-intensity exercise. Some studies suggest potential benefits for the genitourinary system, but evidence is limited. The antioxidant and anti-inflammatory properties of blackcurrant's anthocyanins are believed to contribute to these effects. Effect sizes vary widely, and more research is needed to establish consistent clinical significance. The onset and duration of benefits are not well-defined.
How it works
Blackcurrant's anthocyanins exert antioxidant and anti-inflammatory effects, potentially improving exercise performance by reducing oxidative stress and inflammation. These anthocyanins may interact with cardiovascular and muscular systems to enhance exercise performance. Delphinidin's high hydroxyl group content contributes to its radical scavenging ability. While the bioavailability of anthocyanins is generally low, their metabolites may have higher bioavailability and synergistic effects. These mechanisms collectively contribute to the observed benefits of blackcurrant supplementation.
Side effects
Blackcurrant is generally considered safe when consumed in typical dietary amounts. Common side effects are not well-documented, but may include gastrointestinal upset. Uncommon side effects are rarely reported, but could include allergic reactions. Potential interactions with blood thinners may occur due to its antioxidant properties. Caution is advised in individuals with allergies to berries. Pregnant or breastfeeding women should consult healthcare providers before using supplements. High doses may cause gastrointestinal discomfort. Overall, the safety profile is favorable, but awareness of potential adverse effects is important.
Dosage
The minimum effective dose is not well-established, but typically ranges from 100 to 300 mg of anthocyanin-rich extract per day. Optimal dosage varies by study, often around 100-300 mg. The maximum safe dose is not clearly defined, but high doses may cause gastrointestinal upset. It is best taken before exercise to potentially enhance performance. Capsules or powders are common forms. Bioavailability may be enhanced with food intake. Further research is needed to refine dosage recommendations and establish safety thresholds.
