A good quality mulberry leaf extract can be distinguished by its colour, processing technology as well as species and origins. In terms of colour, premium mulberry leaf extract is bright green in colour; brown colour would suggest a lower quality. The appropriate processing technology is also crucial to the nutritional value of mulberry leaf extract. Low temperature processing is the key to retaining the precious nutrients and active compounds of the mulberry leaf. Lastly, the species and origin of mulberry tree would also make a difference to the quality of mulberry leaf extract. Mulberry trees grown on the coastal regions are sturdier from having to withstand the harsh conditions and the fruits they bear are richer in nutrients.
Fulfilling the above 3 key criteria, the Organic Mulberry Leaf Extract in Mulbiotic would be considered as one of the best mulberry extracts available in the market. It is bright green in colour, processed under low temperature without chemicals and made from the leaves of white mulberry trees grown along the coastal regions of Japan. Mulbiotic delivers exceptionally high amounts of nutrients, including phenolic acids and flavonols.
