Abstract: Some algae, particularly blue-green and green algae, contain very high levels of protein, typically 40 to 60% (of dry matter), that can be used as functional food ingredients. Algal proteins possess a high nutritional value in terms of protein content, amino acid quality and nutritional acceptability If you have not tried algae protein, it is time to consider the benefits of adding it to your diet. Algae supplements appear to be similar to fish supplements. Data indicate that supplementing between 1 and 2 grams of algae oil per day significantly elevates blood levels of DHA and EPA. This dose may also help to lower blood triglycerides, raise HDL, control inflammation, and lower blood pressure and heart rate. Algae also need water and they find their nutrients in the water. Their nutrients are carbon, oxy- gen, phosphorus and nitrogen. ... Algae make their own energy by using: Sunlight + Carbon Dioxide + Water + Chlorophyll Glucose + Oxygen.
