An Atlantic seaweed supplement” usually means a dietary supplement derived from seaweeds (algae) harvested from the Atlantic ocean or nearby coastal waters. These can come in forms like dried seaweed, powders, capsules or liquid extracts. The seaweed may include varieties rich in vitamins, minerals, antioxidants, fiber and other bioactive compounds.
Because seaweed grows in ocean water, it absorbs a wide array of minerals and trace elements naturally — making these supplements often marketed as a “nutrient-dense, natural” alternative to standard vitamin/mineral pills
