What are some algae supplements?

Dried pond scum: Like everything else in nature, algae such as spirulina, chlorella and the curious bacteria called blue-green algae contain biomolecules. You might get them more enjoyably and less expensively from some healthy-raised fruits and vegetables from your local farmer's marker. There's nothing magic here, just advertising. If you are interested in supplements, get with a responsible holistic-focused doc.
