Comparing gram-for-gram, just one gram of PureSeaTM contains around 12 times as much calcium as spirulina, 4 times as much potassium as chlorella, and nearly 30 times as much iron as spinach*, according to our manufacturing partner Seaweed & Co.

Previously marketed by LEHVOSS as GeeSeaNutra®, this extremely nutrient-rich brown algae (also known as Knotted Kelp or Wrack seaweed) has been recently relaunched under the PureSeaTM brand name with a variety of formats, and based on their Patent Pending technologies.  PureSea™ Protect is the latest addition which offers a micro-encapsulated flavourless off-white powder with enhanced nutrition due to protection of key nutrients during digestion according to recent research with Newcastle University Medical School (publication in preparation).
