Gotu Kola Powder Extract
Also known as: Gotu Kola, Asiatic pennywort, Indian pennywort, Jal Brahmi, Mandookaparni, Tsubokusa, Centella asiatica
Overview
Centella asiatica, commonly known as Gotu Kola, is a perennial plant native to the wetlands of Asia and Africa. Used extensively in Ayurvedic and traditional Chinese medicine, it is recognized for its potential health benefits including cognitive enhancement, and improvement in skin and vascular health. The plant contains bioactive compounds such as asiatic acid and madecassic acid, which are thought to exert various therapeutic effects, particularly on the nervous system. Gotu Kola is commonly available in powder, capsule, and tea forms. While preclinical studies suggest its efficacy in treating conditions like venous insufficiency and enhancing cognitive function, human studies are somewhat limited, with varying quality of evidence. Systematic reviews are scarce, but individual studies indicate modest benefits, particularly in elderly populations.
Benefits
Research indicates that Gotu Kola may help improve cognitive function, particularly working memory, with dosages typically around 750 mg/day. However, a meta-analysis found no statistically significant cognitive benefits across multiple studies. Additional evidence supports its use in managing venous insufficiency and promoting wound healing, although these findings are less consistent. Elderly individuals may particularly benefit from cognitive enhancement, but the clinical significance of improvements often appears modest and relies on a longer-term consistent usage. Studies suggest that benefits may become observable within a few months, yet long-term effects are not well-documented.
How it works
Gotu Kola's active components are thought to enhance neuroprotection through antioxidant mechanisms, mitochondrial function, and modulation of synaptic density. It influences key biological pathways associated with oxidative stress and inflammation, thereby potentially facilitating improved cognitive functions and vascular health. Its compounds may particularly target the nervous system, thereby enhancing memory and cognitive capabilities while also improving venous circulation.
Side effects
Gotu Kola is generally regarded as safe, with mild side effects including gastrointestinal discomfort and headache occurring in over 5% of users. Less commonly, some individuals may experience rashes, and in rare cases (<1%), there have been reports of hepatotoxicity. Due to potential liver-related risks, individuals with liver disease should exercise caution. Additionally, while drug interaction data is limited, consultation with healthcare providers is recommended for those on medications. Pregnant or breastfeeding individuals are also advised to seek medical advice due to a lack of comprehensive safety studies.
Dosage
The recommended minimum effective dose of Gotu Kola typically starts at 30-90 mg/day of extract, with an optimal dosage often around 750 mg/day based on cognitive studies. While upper safety limits are not clearly defined, doses up to 1,000 mg/day have been administered without significant adverse effects reported. No specific timing for intake has been established, and the supplement is commonly consumed as a capsule or tea. Bioavailability may be influenced by dietary factors, although the data on absorption is limited.
