If you haven’t heard of “super seaweed,” wakame is here to change that.
A recent study from the University of London found that wakame is not just another superfood with numerous nutritional benefits, but also a natural calcium powerhouse. It offers an excellent alternative for those who cannot consume lactose due to intolerance.
Calcium, as we know, is crucial for healthy bones, muscles, and nerves—and wakame is rich in it. But that’s not all. The researchers showed that wakame is not only packed with calcium, but also enhances the body’s ability to absorb it efficiently, thereby increasing its effectiveness.
“This discovery is a significant breakthrough for lactose-intolerant individuals,” explained one of the lead researchers. “They can now enjoy a high-quality, plant-based source of calcium without relying on dairy products. In addition to calcium, wakame contains other essential vitamins, such as vitamin K and vitamin C, which aid calcium absorption and support overall health.”
However, it is important to note that wakame poses challenges with regard to Jewish dietary laws, as even after thorough cleaning it has been found to contain high levels of insect impurities.
So how can it be consumed? Through certified kosher dietary supplements, which are available at select pharmacy chains.
