Algae and leafy greens—from spirulina and chlorella to spinach and kale—contain compounds that have drawn scientific attention for decades. These foods are rich in chlorophyll, carotenoids, minerals like iron and magnesium, and various phytochemicals. Understanding what research actually shows about how these substances work in your body, and where claims outpace the evidence, helps you make informed choices about whether and how to use them.
The articles here explore what happens when you consume these foods: how your body absorbs their nutrients, what human studies reveal about their effects on energy, immunity, and disease risk, and which popular claims rest on animal research rather than trials in people. You'll find information about the differences between whole greens and concentrated supplements, and what questions scientists still haven't fully answered.
