Caulerpa contains a high amount of iron (up to 81.3 mg per 100 g of dry matter in C. racemosa), [26] magnesium, and calcium. [24] Water content is species-specific and generally ranges from 75 - 94%. [24] The genus is known to have a high bioaccumulation rate, [27] [20] [28] which can make it less than ideal to consume on a regular basis.
