Spirulina For Vegetarians And Vegans: What Are Its Benefits?
Both vegetarians and vegans are at-risk populations when it comes to nutritional deficiencies.

What are the benefits of spirulina for vegetarians and vegans?
Helps Complement Protein Intake
One of the disadvantages of vegetarian and vegan diets is protein intake. Removing animal products from food means losing proteins of high biological value.
Those of plant origin have deficiencies in essential amino acids, apart from a lower digestibility.
Spirulina is a protein-containing algae. It presents a high percentage of them concerning its total composition. For this reason, it included in the framework of a vegan diet to seek to complete the protein intake.

However, the fundamental deficiency of vegan diets is vitamin B12. Spirulina contains it, but in a form that is not assimilable by the human body.
For this reason, the algae are not capable of meeting the requirements of said nutrient in vegans.
