Chlorella and spirulina deliver a number of nutrients. A 1-ounce gram serving of these algae contains the following 2 , 3 :. While their protein, carbohydrate, and fat compositions are very similar, their most notable nutritional differences lie in their calorie, vitamin, and mineral contents. Both algae are particularly rich in polyunsaturated fats , especially omega-3 fatty acids 4 , 5 , 6 , 7.
Omega-3 and omega-6 fatty acids are essential polyunsaturated fats that are important for proper cell growth and brain function 8. Therefore, you must obtain them from your diet 8. Intake of polyunsaturated fats has been associated with a lower risk of heart disease, particularly when substituted for saturated fats 9 , 10 , 11 , Omega-3 fatty acids, in particular, are associated with numerous health benefits , including reduced inflammation, improved bone health, and a lower risk of heart disease and certain cancers 8 , 13 , However, you would need to consume very large amounts of these algae to meet your daily omega-3 needs.
People typically only consume small portions of them However, a study that analyzed the fatty acid contents of these algae found that chlorella contains more omega-3 fatty acids, while spirulina is higher in omega-6 fatty acids 5 , 6.
Though chlorella offers some omega-3 fats, concentrated algal oil supplements are a better option for those seeking alternatives to animal-based omega-3 supplements. In addition to their high levels of polyunsaturated fat, both chlorella and spirulina are very high in antioxidants.
These are compounds that interact with and neutralize free radicals in your body to prevent damage to cells and tissues In one study, 52 people who smoked cigarettes were supplemented with 6. Both of these vitamins have antioxidant properties Furthermore, those who received a chlorella supplement also showed a significant decrease in DNA damage In another study, 30 people with chronic obstructive pulmonary disease COPD consumed either 1 or 2 grams of spirulina daily for 60 days.
Civilizations as far back as the Aztecs have used algae, such as spirulina and chlorella, as food 1. Due to its high protein content, NASA has used spirulina as a dietary supplement for their astronauts during space missions Currently, scientists are investigating chlorella as a potential high protein, nutritious food source for longer missions in space 20 , 21 , The protein found in both spirulina and chlorella contains all essential amino acids , and your body easily absorbs it 23 , 24 , Chlorella is rich in omega-3 fatty acids, vitamin A, riboflavin, iron, and zinc.
Spirulina contains more thiamine, copper, and possibly more protein. Numerous studies have shown that both chlorella and spirulina may benefit blood sugar management.

Higher levels of proteins in the plant world, vitamins of all groups, trace elements, minerals, amino acids, unsaturated fatty acids: no doubt, some algae have a beneficial effect on our health.
Spirulina, chlorella and klamath are among the "remarkable micro-algae". But what are the differences between these three algae? Here are the answers. Wild or cultivated algae Spirulina, chlorella and klamath are all blue-green algae or cyanobacteria , known for their health benefits. It is freshwater algae, rich in protein, vitamins and minerals. Blue-green algae is a group of primitive bacteria, known as cyanobacteria, which exhibit photosynthesis, reports Purdue University plant pathologist, Carole A.
Within this group is spirulina, a one-celled organism found in fresh waters of alkaline state. Spirulina derives its name from its spiral shape as seen under the microscope. Natural Ways to Health reports that as a single-celled organism it is uniquely large, with sizes equalling 0. This unique property makes some cells of spirulina visible to the naked eye. In desert conditions, some species of blue-green algae survive when the water source evaporates and temperatures reach degrees F.
Spirulina's ability to thrive in waters between 85 to degrees F and in alkalinity from 8 to 11 pH make it a hygienic food source, as other organisms cannot survive in the same conditions, according to Natural Ways to Health.
As spirulina grows, the plants bunch together, sticking to one another, allowing for easy harvest. Spirulina also reproduces very fast. Health benefits, from weight loss to cancer prevention, have been purported for blue-green algae products, according to the University of California Berkeley, which does not endorse the products for these purposes.
General nutritive value derived from spirulina includes protein, B vitamins, beta-carotene, several minerals and gamma-linolenic acid.
