Latvian Scientists Unlock St. John's Wort as a Rich Vitamin E Source

A research project in Latvia has explored St. John's wort as a possible source of vitamin E. Scientists grew 40 varieties of the plant to identify those with the highest concentrations. The findings suggest it could become an alternative way to obtain this essential nutrient in the region.

The study took place in Dobele, where 12 species of St. John's wort were cultivated and analysed. Researchers focused on their tocotrienol content, a form of vitamin E known for its antioxidant benefits. Four of these species showed particularly high levels and were selected for further testing.

The team then examined how different growing conditions affected vitamin E accumulation. Plants raised in greenhouses produced significantly higher concentrations than those grown outdoors. This discovery led to a partnership with a local company to develop a prototype product. The new item extracts vitamin E compounds directly from the plant.

Vitamin E is valued for its ability to neutralise free radicals, which can damage cells. If successful, this project could offer Latvia a homegrown source of the nutrient, reducing reliance on imports.

The research confirms that St. John's wort thrives in Latvian conditions and can yield useful amounts of vitamin E. A prototype product has already been created, marking a step toward commercial use. Further development will determine whether large-scale production becomes viable.
