Best Spirulina Powder Supplements (And Why They Are Worth Your Money)

One of the most popular and hyped up health foods from recent years is spirulina. Some say it’s a fad that will just disappear as time goes by, others say it’s the greatest thing since sliced bread.

I usually don’t get too excited about just one food in particular. Rather, I prefer to focus on maintaining a healthy balanced diet, eating a wide variety of different foods that all offer their own unique sets of nutrients and health benefits.

But there’s no denying that spirulina has a very rich nutritional profile. So much so that I use spirulina powder as a regular ingredient for my green smoothies. It’s just very convenient for me to add a teaspoon of spirulina powder each time I prepare a smoothie and enjoy its health benefits that way.

Let’s have a closer look at what spirulina actually is and what some of the best spirulina powder supplements are.

What is Spirulina?

Spirulina is an exotic word for blue-green algae that is suitable for consumption by humans.

Typically found in tropical waters with high-salt content, spirulina has been cultivated worldwide for many years due to its strong nutritional profile and health benefits.

Spirulina can be consumed either as a whole food or as a dietary supplement, usually in the form of powder or tablets. As a food, spirulina has quite a strong seaweed flavor which is why some prefer to consume it in powder form.

It’s essential to only consume spirulina that has been grown in clean, non-contaminated waters. The below listed supplements are from reputable brands that make sure their products are clean and thoroughly tested.

Health Benefits of Spirulina

So why should you consider adding spirulina to your diet? If you have a closer look at its nutritional profile below, it becomes immediately clear that spirulina is perhaps one of the most nutrient dense foods in the world. As a result, its health benefits are numerous.

With 58g protein per 100g, dried spirulina is one of the most popular sources of protein for vegans. Spirulina is also extremely rich in iron, an essential mineral that assists in various functions in our bodies, such as creating red blood cells.

In addition, dried spirulina is a great source of various B vitamins, in particular vitamins B1 (thiamin) and B2 (riboflavin).

While each B vitamin has its own unique benefits and responsibilities, in general the B vitamin family helps to produce necessary energy from the food that we eat and supports normal nervous system function. B vitamins also play a crucial role in forming red blood cells.

And with a staggering 195mg of magnesium content (55% DV), dried spirulina is a good candidate to be added to my list of favorite magnesium rich foods.

Final Thoughts

Spirulina and turmeric are my two favorite supplements that I find worth buying. Spirulina has an incredibly rich nutritional profile and in powder form it’s very easy to add to green smoothies.

But with any so-called “superfood”, moderation is key. There is absolutely no point in overdosing yourself with a popular food such as spirulina.

Superfoods don’t really exist, it’s simply a marketing term for popular products that happen to be nutrient dense. Your diet should consist of a wide variety of different foods that all offer their own nutrients and health benefits.

A spirulina powder supplement can be a very welcome addition to a balanced diet. Not as a treatment for health issues, but to simply get your nutrients in that your body will appreciate.
