Organic Black Currant Powder

Also known as: Blackcurrant, Black Currant, *Ribes nigrum*

Overview

Blackcurrant (*Ribes nigrum*) is a nutrient-rich fruit, renowned for its high concentration of anthocyanins, which are potent antioxidants. This supplement can be ingested in various forms, including juice, extracts, and powders. Its primary applications include enhancing athletic performance, promoting cardiovascular health, and supporting gut health. The maturity of research on blackcurrant reveals moderate quality, with several studies indicating its positive effects on exercise performance and gut microbiota. Varied research quality exists, with systematic reviews and randomized controlled trials (RCTs) providing robust evidence, while other areas remain under-researched. Blackcurrant is considered safe for consumption, with no significant adverse effects identified, making it a favorable addition to dietary supplements.

Benefits

1. **Athletic Performance**: Evidence indicates a small yet significant improvement in athletic performance with a standardized effect size of 0.45 (95% CI 0.09-0.81, p = 0.01) in individuals consuming blackcurrant supplements. Athletes may find the most benefit from supplementation. 2. **Gut Health**: Blackcurrant acts as a prebiotic, improving the population of beneficial gut bacteria, which can enhance overall digestive health. This effect was evidenced in an RCT showing increased beneficial bacteria and reduced harmful enzymes in a human sample. 3. **Insulin Sensitivity**: Preliminary animal studies suggest that blackcurrant extracts could improve insulin sensitivity and positively influence gut microbiome profiles, particularly in models of type 2 diabetes. Overall, blackcurrant demonstrates potential across various health-related areas, with athletes and diabetic individuals likely to see the most pronounced effects.

How it works

The health benefits of blackcurrant are primarily attributed to its anthocyanin content, which exerts antioxidant and anti-inflammatory effects. These compounds are believed to enhance athletic performance by improving blood flow through increased nitric oxide production and modulating systemic inflammation. Additionally, blackcurrant may positively impact the gastrointestinal system by influencing gut microbiota composition, promoting beneficial bacteria while suppressing harmful strains. Although anthocyanins generally exhibit low bioavailability, they are quickly absorbed and metabolized, allowing them to exert their effects effectively in the body.

Side effects

Organic blackcurrant powder is widely regarded as safe with no known significant side effects reported in scientific literature. Some minor gastrointestinal discomfort may occur, although this is not frequently documented. There are no identified drug interactions or contraindications associated with blackcurrant supplements, making them suitable for most individuals. However, it is advisable for pregnant or breastfeeding women to consult healthcare providers before integrating blackcurrant into their regimen. Overall, the safety profile appears favorable with no major health risks reported, reinforcing its potential as a beneficial nutritional supplement.

Dosage

For enhancing athletic performance, recommended dosages of blackcurrant powder range from 105 to 210 mg of total anthocyanins. Optimal dosages for other health benefits, such as gut health or metabolic improvements, have yet to be firmly established due to limited research. While clear maximum safe doses are not defined, typical consumption levels are considered safe. To maximize the exercise-related benefits, consumption shortly before physical activity is advised. Different forms of blackcurrant, including powder or extracts, may vary in absorption rates, so consumers should consider these factors when selecting their supplements.
