So, Healthy Line, offers 5 evidence-based health benefits of spirulina.
1- Spirulina is rich in many nutrients.
The standard daily dose of spirulina is 1-3 grams, but doses of up to 10 grams per day have been used effectively.
These small algae are packed with nutrients One tablespoon (7 grams) of dried spirulina powder contains:
Protein: 4 grams
Vitamin B1 (thiamine): 11% of the RDA
Vitamin B2 (riboflavin): 15% of the RDA
Vitamin B3 (niacin): 4% of the RDA
Copper: 21% of the RDA
Iron: 11% of the RDA
It also contains adequate amounts of magnesium, potassium, and manganese, and small amounts of all the other nutrients you need.
Plus, the same amount contains 20 calories and 1.7 grams of digestible carbs.
Gram for gram, spirulina may be the most nutritious food on the planet.
A tablespoon (7 grams) of spirulina provides a small amount of fat – about 1 gram – including both omega-6 and omega-3 fatty acids in a ratio of roughly 1.5-1.0.
The protein quality in spirulina is excellent – it compares to eggs. It gives all the essential amino acids you need.
It is often claimed that spirulina contains vitamin B12, but this is wrong. It contains false vitamin B12, which has not been shown to be effective in humans.
2- It has powerful antioxidant and anti-inflammatory properties
Oxidative damage can damage DNA and cells. This damage can lead to chronic inflammation that contributes to cancer and other diseases. Spirulina is a great source of antioxidants that can protect against oxidation.
3- It can lower levels of LDL and “bad” triglycerides
Heart disease is the leading cause of death in the world, and many risk factors are associated with an increased risk of heart disease.
As it turns out, spirulina has a positive effect on many of these factors. For example, it can lower total cholesterol, bad LDL cholesterol and triglycerides, while raising the “good” HDL cholesterol.
In a study in 25 people with type 2 diabetes, taking 2 grams of spirulina per day significantly improved these markers.
Another study in people with high cholesterol determined that 1 gram of spirulina per day reduced triglycerides by 16.3% and the “bad” LDL by 10.1%.
Several other studies have found positive effects – despite higher doses of 4.5-8 grams per day.
4- It protects LDL cholesterol from oxidation
The fat structures in your body are subject to oxidative damage.
This is known as lipid peroxidation, and it is a major driver of many serious diseases.
5- It may have anti-cancer properties
Some evidence reports that spirulina has anti-cancer properties.
Animal research indicates that it can reduce cancer incidence and tumor size.
The effect of spirulina on oral cancer – or mouth cancer – has been particularly well studied.
One study examined 87 people from India with precancerous lesions – called oral submucosal fibrosis (OSMF) – in the mouth.
Among those who consumed 1 gram of spirulina daily for one year, 45% observed the disappearance of their lesions – compared to only 7% in the control group.
When these people stopped taking spirulina, nearly half of them developed the lesions the following year.
In another study in 40 people with OSMF lesions, 1 gram of spirulina daily led to greater improvement in OSMF symptoms.
