Today let’s talk about why astronauts use spirulina. Spirulina is a type of dark green algae that is super concentrated with all sorts of nutrients.

Astronauts have a unique problem. They have to prevent certain health issues, such as:

1. Bone density depletion

2. Muscular atrophy

3. Metabolic rate change

4. Loss of body mass

5. Cardiovascular breakdown

6. Decreased immune system

Astronauts have to carry food that is persevered, dehydrated, or freeze-dried. They are also in an environment where they are exposed to high amounts of radiation, and they have to artificially regulate the oxygen, CO2, and temperature in the environment.

NASA did a research project in the 70s that concluded that spirulina is one of the most powerful concentrated foods available to mankind for increased immune function and removing toxins. They also stated that the nutrient value of 1000kg of fruits and vegetables equates to 1kg of spirulina.

Benefits of spirulina:

• It’s loaded with potassium, calcium, magnesium, and beta carotene

• It has all 8 essential amino acids

• It’s a nutrient-dense superfood

• It has iron and folate (it has 6x more absorption than normal iron supplements)

• It has a lot of phytochemicals (can help remove toxins and improve immunity)
