Don’t you wish to go back to the time when you weighed 10 pounds less? Are you bored of wearing loose clothes, dark jeans, and body shapers to hide your figure? The fact is, these clothes cannot protect you from obesity-related diseases such as PCOD, diabetes, cardiovascular disease, and infertility. But losing weight can.
If you are serious about getting back in shape, do more than just eating healthy and exercising. Having supplements can speed up the process, and one such natural weight loss supplement is spirulina (1).
This biomass of blue-green algae has been branded as “Best Food for the Future” by the UN for many reasons, weight loss being one of them (2). Read on to find out how spirulina aids weight loss, where to buy it, dosage, and more.

How Spirulina Aids Weight Loss
Spirulina is low in calories and high in protein. It has antioxidant and anti-inflammatory properties, suppresses appetite, boosts fat mobilization, and lowers blood sugar and blood pressure. All of these factors aid weight loss.
Spirulina is a biomass of floating microalgae found mostly in the water reservoirs of Africa, India, Mexico, and America (3). It is highly nutritious, a reason it was promoted by the Intergovernmental Institution for the use of Micro-algae Spirulina Against Malnutrition (IIMSAM) to fight starvation and malnutrition (2).
The NASA recommends spirulina as food for astronauts on a space mission (4). It is also consumed by soldiers during wars that last long. Here is how spirulina benefits weight loss.
1. Low In Calories
One tablespoon (7 g) of spirulina contains only 20 Calories (5). Consuming low-calorie foods is critical if you want to lose weight. It will help create a negative energy balance. You can add spirulina to your morning smoothie or juice without having to worry about consuming too many calories.
2. High In Protein
When it comes to weight loss, a low-carb and high-protein diet works for most dieters. Spirulina contains about 60-70% protein and contains all the essential amino acids (5).
Proteins take longer to digest than simple carbs. Hence, spirulina can keep you full for longer (6). Also, proteins help build lean muscle mass, thereby making you look toned and increasing your muscle power and endurance and preventing post-exercise muscle damage (7).
3. Is Highly Nutritious
Spirulina is rich in vitamins C, B1, B6, B5 and E, minerals, such as copper, zinc, and manganese, useful enzymes, and dietary fiber that makes it a perfect weight loss supplement (5). These minerals, vitamins, enzymes, and dietary fibers help in digestion and metabolism, eliminate toxins, and prevent fat absorption.
4. Has Antioxidant And Anti-Inflammatory Properties
Spirulina has antioxidant and anti-inflammatory properties (8). The antioxidants help to nullify the harmful oxygen radicals and prevent the body from producing pro-inflammatory molecules. This prevents the body from being in a state of stress and curbs inflammation. Toxic build-up and inflammation are two leading factors of weight gain, which spirulina can prevent.
5. Suppresses Appetite
Spirulina is also an appetite suppressant. It contains the amino acid phenylalanine that stimulates the secretion of cholecystokinin that helps to suppress appetite (9).
6. Lowers Cholesterol Levels
Many scientific studies conducted to find the benefits of spirulina have confirmed that spirulina possesses lipid-lowering properties. It helps lower bad cholesterol (LDL) and triglyceride levels and increase good cholesterol (HDL) levels in the blood. Consuming spirulina can boost fat mobilization, which is what is critical for weight loss (10), (11).
7. Lowers Blood Sugar
High blood sugar can increase the risk of developing insulin resistance, obesity, PCOD, and diabetes. Spirulina helps lower the blood sugar levels in individuals with type 2 diabetes. Including spirulina in your diet can help in regulating insulin spikes, protecting you from diseases and preventing weight gain (12).
8. Lowers Blood Pressure
Spirulina also helps to lower systolic and diastolic blood pressure, making it a potent antihypertensive agent. High blood pressure and stress lead to weight gain. Spirulina supplementation can lower the concentration of fats in the blood, thus preventing weight gain (13).
These are the 8 reasons spirulina is considered one of the best weight loss supplements. Now, let’s find out how you can consume spirulina
and take a look at the spirulina dosage for weight loss in the powder and tablet forms.
- Stir a tablespoon of spirulina powder into your juice or smoothie.
- Stir a tablespoon of spirulina powder into a glass of water.
- Add a tablespoon of spirulina powder to your salad, soups, homemade salsa sauce, curries, and stir-fried veggies.
- Add ½- 1 tablespoon spirulina to your cakes, pastries, and homemade energy bars.
If you want to take spirulina tablets, it is safe to take a 500 mg tablet 3-4 times a day. But make sure you talk to your doctor before using spirulina for weight loss.
The dose may vary with the problem. Further studies are required before a therapeutic recommendation is established.
But is consuming spirulina is safe?
The FDA has approved spirulina as safe for consumption. However, it is best to consult a doctor because you may be allergic to spirulina, do much better by consuming any other natural weight loss supplement, or not even need to consume spirulina.
Also, avoid consuming spirulina if you are allergic to seafood or have hypothyroidism. Though it is safe for consumption, you may feel feverish or fatigue after you consume spirulina.
Here is a list of things you should consider before buying spirulina for weight loss.

You may buy spirulina online or at any pharmacy nearby. Check the label for the expiry date, buy from a known brand, and ensure it is organic.
