Ecklonia Stem And Leaf Extract
Also known as: *Ecklonia maxima*, Kelp, Brown Seaweed, Ecklonia, *Ecklonia cava*
Overview
Ecklonia species are brown seaweed found in coastal waters and are recognized for their abundance of bioactive compounds, including fucoidan and dieckol. These compounds are linked to various beneficial properties, particularly in agriculture and human health. As biostimulants, they are employed to enhance plant growth by improving factors such as nitrogen use efficiency and water use efficiency. In the context of dietary supplements, *Ecklonia* extracts are investigated for their potential antioxidant, anti-inflammatory, and antiviral effects, with some studies highlighting significant efficacy in vitro, although robust evidence in humans is still emerging. The research maturity level regarding its health benefits is moderate, with ongoing investigations needed to validate its health claims and usage guidelines.
Benefits
In agricultural contexts, *Ecklonia* extracts have been shown to significantly increase fresh and dry biomass, enhance leaf expansion, and improve yield in crops like leaf lettuce, with a noted 32.6% to 37.5% increase in biomass at various concentrations. Furthermore, these extracts improve water and nitrogen use efficiency, making them valuable for sustainable farming practices. For human health, *Ecklonia cava* extracts exhibit potent antiviral activity against the Zika virus with an IC₅₀ of 4.88 μM. The antioxidant and anti-inflammatory properties of its bioactive compounds are also promising, although human clinical data is limited. Current evidence suggests that populations such as athletes or individuals looking for natural anti-inflammatory supplements may benefit from *Ecklonia* extracts.
How it works
The bioactive compounds in *Ecklonia* extracts, particularly fucoidan and dieckol, interact with several biological pathways. Dieckol has demonstrated the ability to form stable complexes with Zika virus proteins, inhibiting viral replication mechanisms, which contributes to its antiviral efficacy. In plants, these compounds enhance growth by facilitating nutrient uptake and improving both water and nitrogen use efficiencies. Additionally, the antioxidant and anti-inflammatory activities may positively influence immune and metabolic systems in humans by mitigating oxidative stress.
Side effects
The safety profile for *Ecklonia* extracts indicates that they are generally well-tolerated with no specific adverse effects definitively established. There is no substantial evidence identifying common or rare side effects, and no interactions with medications have been documented. However, comprehensive safety studies in humans are lacking. Special populations such as pregnant or breastfeeding women, and individuals with existing health conditions, should consult healthcare professionals before starting new supplements, particularly due to the absence of established safety thresholds.
Dosage
Dosage recommendations for *Ecklonia* extracts remain largely undefined for human health benefits, as there are no established minimum effective doses due to limited clinical trials. In agricultural applications, effective concentrations range from 1 to 4 mL L⁻¹. The most common forms of these extracts are liquid or powdered, and absorption could vary based on the preparation. No maximum safe doses have been identified, nor specific timing considerations. As research progresses, more precise dosage guidelines may emerge.
