Among the best superfoods, moringa and spirulina rank at the top of the list. Both plants are packed with powerful nutrients, minerals, and many bioactive compounds you need for a healthy body. However, moringa superfoods are probably the most popular because of their health and medicinal properties.

But which among these two plants is the healthiest? Well, both are superfoods that offer excellent nutrition content. But if you have to choose one of them, you need to compare the main nutrients and minerals to see which one is the most powerful.

To help you make the right choice between moringa vs spirulina, we are going to compare three main things: nutrient content, antioxidants content, and lastly, side effects and safety.

1. Nutrient content

Both superfoods are packed with almost the same nutrients and minerals. What differs is the amount each of them has. In this comparison, we will use 10g of each food to determine how much of these nutrients they contain.


One of the reasons why most people are going to moringa is because of the said high protein content. But you will be surprised to learn that spirulina is richer in protein than moringa. In fact, it has more than double protein content than moringa. In every 10g of spirulina, 5.75g is protein, while moringa is just 2.7g. If you were wondering why people refer to spirulina as protein beast, that’s the reason. If you are looking for proteins only in your superfood, you should go for spirulina.


Calcium is one of the essential minerals for healthy bones and teeth. If you are pregnant or have small kids, you need a diet rich in calcium. If you compare the two superfoods, moringa is the richest when it comes to calcium content. It has about 174mg calcium for every 10g, while spirulina has 12mg -that’s 14 more times than spirulina.

Iron is another mineral that’s very vital to our body health. You need iron to prevent anaemia, which is a deadly disease caused by iron deficiency. Iron also helps to boost haemoglobin in the blood as well as reduce fatigue. Did you know iron boosts immunity and concentration? Now you know. Moringa has 5 times more iron than spirulina. For every 10g of moringa powder, there is 15.7mg iron, while spirulina has 2.85mg in a 10g.


Fibre is a non-digestible carbohydrate that helps to improve gut health. It keeps your digestive system healthy and, more so, the bowel moving. If you are eating enough fibre (20-30g) per day, then you’ll never have problems with indigestion and constipation. Did you know that moringa has almost 10 times fibre than spirulina? Well, it has about 3.3g, while spirulina has 0.36g.

Vitamin A

You need enough amount of vitamin A for healthy skin, good vision, teeth, and other soft and skeletal tissue. But most importantly, this vitamin is crucial in protecting your sight. The vitamin also lowers the risk of certain cancers and boosts immunity. If you want a superfood rich in Vitamin A, go for moringa. The plant leaves have about 16 times vitamin spirulina.

Vitamin C

Vitamin C, commonly known as ascorbic acid, helps in growth, development, and body tissue injuries repair. It is the mineral that keeps your immune system in shape to protect you from diseases. Spirulina is richer in ascorbic acid compared to moringa. However, the difference is very small. While spirulina is at 1.01mg, moringa is at 0.99mg.

Potassium is one of the crucial minerals in the body. It’s a mineral that helps in regulating muscle contractions, nerve signals, and fluid balance. Potassium also helps reduce blood pressure and the risk of stroke. It’s also the mineral that boosts water retention, among many other health benefits. Both superfoods have a high potassium content, but moringa is more packed with 140mg in every 10g. Spirulina has around 136.3mg potassium per every 10g.


Carbohydrates are energy giving foods. You need carbs to provide the body with energy to do things, including the function of body parts such as the brain. If you take 10g of each superfood, moringa has 5.1g while spirulina has around 2.39g. This shows if you need more energy, moringa is the food to add to your list of superfoods.

When compared in terms of major nutrient content, moringa images the winner. Of the 8 nutrients, moringa has a higher content in most of them

2. Antioxidant Content

Apart from Vitamin c, a powerful antioxidant, your body needs many other compounds to stay healthy. Although both superfoods are rich in antioxidants, moringa has more antioxidants compounds.

Various research works have shown that moringa has over 40 antioxidants. This makes it more powerful than spirulina. However, spirulina only falls short by a few antioxidants. But if it’s about to select the food that’s rich in antioxidants, moringa is the winner.

3. Side Effects and Safety

In all superfoods, the side effects and safety are two crucial factors to take into consideration. Of the two foods, moringa is largely considered side effects free. So far, there has never been a case of side effects, and the plant has been used for years. However, moringa roots can be poisonous. That’s why leaves, fruits, and seeds are the widely used parts.

Spirulina has been associated with several side effects. People have complained of dizziness, stomach ache, headaches, and constipation after taking it. In fact, not everyone can take this food because the side effects might get worse. If you have gouts, kidney stones, or any thyroid condition, don’t take spirulina in any form.

Bottom Line

When doing a moringa vs spirulina comparison, note that both are superfoods rich in nutrients and minerals. Although spirulina is a protein beast, it falls short of essential nutrients when compared to moringa. That’s the reason why moringa is considered an all-around, more nutritious food. Moringa is also side effects free. These are just some of the reasons why it emerges as the best superfood in this comparison.
