What is Spirulina?

Spirulina is a blue-green algae that grows best in fresh and alkaline water and is known for having many nutrients. Its blue-green colour comes from the high chlorophyll and phycocyanin in its spiral-shaped cell structures.^[1]

Spirulina tastes earthy and slightly like seaweed, though that can be easily covered up when added to drinks or blended with fruits. In India, Tamil Nadu, Maharashtra, and Rajasthan are well known for farming spirulina due to their warm, alkaline water bodies.

Health Benefits of Spirulina

Spirulina is rich in nutrients that benefit your overall health and well-being. Below are some key health benefits of including spirulina in your diet. 

#1 Digestive Health Support

Spirulina might help your digestion by making it easier for your body to get rid of toxins and supporting good bacteria in your gut. It may help maintain gut bacteria balance by supporting the growth of beneficial bacteria, such as Lactobacillus and Prevotella.^[4]

This balance helps your body digest food and feel better overall. Additionally, spirulina contains antioxidants that may help manage inflammation in the digestive system, making it more comfortable for individuals with such issues. 

Spirulina may help your digestion by boosting healthy bacteria and protecting the gut, therefore reducing signs of bloating and better nourishing your body. ^[5]Furthermore, spirulina might help strengthen the gut wall and manage the risk of some harmful stuff getting into the blood, which can be good for your health in general.

#2 Antioxidant Benefits

Antioxidants in spirulina help keep the body’s cells healthy by guarding them against damage. Spirulina’s special blue-green hue comes from its main antioxidant, phycocyanin. In addition to phycocyanin, spirulina provides numerous other antioxidants, including beta-carotene, as well as various vitamins and minerals that benefit our overall health.^[6]

The antioxidants present might protect the body from the harmful effects of increased oxidative stress.

#3 Blood Sugar Support

Taking spirulina could help maintain balanced blood sugar levels for those with type 2 diabetes. It can also help you achieve a lower fasting blood sugar level, which is the amount of glucose in your blood after not eating for some time. 

Phycocyanin, polysaccharides, and GLA have been identified as bioactive factors that manage blood glucose and make insulin more effective. Some studies found that adding spirulina to your diet may help you control blood glucose and HbA1c levels when you have type 2 diabetes. ^[7]

Spirulina may improve insulin response by helping the body better manage blood sugar levels. The body can use glucose more efficiently for energy with better insulin sensitivity. Spirulina may also help manage cholesterol and triglycerides, both of which tend to be higher among people with diabetes. 

By supporting both blood sugar and fat levels, spirulina could help promote good health.^[8]

#4 Cholesterol Management

Spirulina is believed to help regulate cholesterol levels. It may help in managing the risk of getting cardiovascular diseases. Taking spirulina orally may help with both high and low blood pressure.^[9] It can help lower total cholesterol and LDL, often referred to as bad cholesterol, as well as triglycerides, a type of fat in the blood. Similarly, people may find that spirulina helps raise HDL cholesterol, which helps keep the heart healthy. ^[10]

This occurs because spirulina naturally contains phycocyanin, an antioxidant and anti-inflammatory compound. It is thought that spirulina may help manage overall cholesterol by absorbing less from food and aiding in the removal of extra cholesterol through bile.^[11] The hormone may also affect the way the body processes fats. As a result, your heart might work better, and your cholesterol could return to a healthy range.

#5 Immune Support

Spirulina’s nutrients could enhance your immune system. It can help increase the number of white blood cells that are responsible for guarding against diseases. Since spirulina contains antioxidants, it may help neutralise harmful molecules and reduce inflammation in the body.^[12]

Due to its rich content of key nutrients, spirulina may offer beneficial support for our immune system. Spirulina may also help manage allergy symptoms and support the immune system further.

Research indicates that spirulina possesses antiviral properties. According to research, a sulfated polysaccharide called calcium spirulan, derived from spirulina, helps protect against viruses by blocking their entry into cells and thereby strengthening the immune system.^[13]

#6 Hair Benefits

Spirulina may benefit hair health because it contains lots of essential nutrients, vitamins, minerals, proteins, and amino acids. It is almost 70% protein, and this protein has all the essential amino acids needed for keratin, which makes up hair strands. 

In addition, vitamins A and B may help promote healthy scalp cells and support increased hair growth by improving blood flow to the follicles. Vitamin C protects your hair follicles by acting as an antioxidant. 

Iron may help increase the flow of oxygen to the follicle, zinc helps regulate the body’s sebum levels and healing, and magnesium keeps calcium from building up and stopping growth. Also, both omega-3 and omega-6 fatty acids help manage inflammation and increase blood flow to the scalp, making sure your follicles get the necessary nutrients. Spirulina’s phycocyanin may give antioxidant support to the cells in hair follicles. 

Using spirulina in your regular diet or hair care products can make your hair stronger, help it grow, and maintain scalp health, which makes it a useful natural product for your hair.^[14]

#7 Nourishes Skin Health

Antioxidants, vitamins, and minerals found in spirulina are beneficial for skin health, as they protect from stress and inflammation. Vitamin A found in it helps skin cells regenerate and repair, and vitamin C increases collagen, which is essential for elastic skin and fewer wrinkles. ^[15]

B vitamins in the skin help maintain moisture levels and support the defense system. Zinc helps control the amount of oil in the skin and promotes effective wound healing. Because of phycocyanin, spirulina protects the skin from damage caused by the environment and contributes to a younger, healthier complexion. ^[16]

Eating spirulina may make your skin healthier and more resilient.

How to Incorporate Spirulina into Your Diet

Here are some simple and delicious ways to work spirulina into your meals.

• Using Spirulina Powder

Adding spirulina to dips like guacamole, hummus, or pesto gives you an extra nutritious boost. You can toss it on top of salads or popcorn for an extra kick of flavour. Consider making your energy balls or granola bars using peanut butter. Spirulina is known for its distinctive, earthy, seaweed-like taste, which is not to everyone’s liking.

• Taking Spirulina Tablets

 If you don’t enjoy the taste, take spirulina in tablet or capsule form instead.

• Adding Spirulina to Drinks

Spirulina powder mixes well into smoothies and increases their nutritional value. It can also be mixed into sweet fruit juices since the sugar hides the algae’s natural flavour.

Possible Downsides of Spirulina

Most studies suggest that spirulina is a safe dietary supplement that can provide antioxidant benefits. But spirulina may not be right for people who have any of these conditions:

• Digestive discomfort: When using spirulina, some people may initially have light stomach problems such as nausea, bloating, or cramping. Usually, these signs improve as the body becomes accustomed to the medicine.
• Allergic reactions: Even when it is rare, some people are sensitive to seafood or seaweed and can react to spirulina. If you experience itchiness, swelling, or difficulty breathing, stop using the medication and consult your doctor.^[17]
• Not suitable for autoimmune conditions: As spirulina might activate the immune system, it could be troublesome for those with autoimmune diseases. They should always consult a healthcare expert before using dietary supplements.^[18]
• Risk for people with PKU: Phenylketonuria (PKU) is a condition everyone should know about. Patients with PKU cannot handle an amino acid called phenylalanine, which exists in spirulina and other protein-containing foods. A build-up of phenylalanine can occur in people with PKU if they overeat this amino acid.^[19]
• Pregnancy and breastfeeding caution: Before you start using spirulina, pregnant or breastfeeding women should check with their doctor to prevent any risks for their baby.^[20]
• Quality concerns: Unsafe sources may allow contamination with toxins or bacteria to enter your spirulina. Whenever possible, opt for products sold by reputable brands to minimize the risk.
• Potential overdose risks: Having too much spirulina could bring about specific side effects. Giving the correct recommended amount of medication can prevent these issues.
