Benefits of Spirulina

Spirulina has dozens of health benefits which makes it a great supplement for a healthy lifestyle. We’re going to take a look at some of the most exciting benefits in more detail.

1. A Natural Multivitamin

First and foremost, spirulina supplements are incredibly rich in nutrients.

It’s so nutrient-dense in fact, that NASA once suggested that it be grown in space as an efficient source of food for astronauts.

What exactly can you expect to find inside your spirulina supplement?

Well, in a serving of 7g, which is 1 tablespoons’ worth, you’ll be getting:

  • 4g of Protein
  • 1g of Fat (omega-6 and omega-3 fatty acids)
  • Vitamins B1, B2, and B3 (thiamine, riboflavin, and niacin respectively)
  • Copper (21% of the RDA)
  • Iron (11% of the RDA)

Not bad, right?

There’s also a considerable amount of magnesium, manganese, potassium, and a healthy dose of other nutrients packed within this small serving.

Due to just how nutritionally-dense spirulina is, some have claimed that is the single most nutritious food we know of. 

That’s a huge claim, and if true, begs the question as to why you wouldn’t want to supplement with this real superfood?

2. Fights Fatigue

Unless you’re superhuman, you probably get tired from time to time. Fatigued, even. If you’re constantly on the move juggling your work, social life, and a bunch of other things, you’re bound to hit a brick wall every now and again.

Caffeine will help get you over the wall, but you shouldn’t rely on it. Too much caffeine can create dependency, and you might end up desensitising yourself to its stimulating effect.

That’s why a healthy alternative like spirulina can help give you the energy boost you need just when you need it. Unlike stimulants this supplement can reduce symptoms of fatigue without the harsh comedown.

Spirulina has been shown to increase the time it takes people to reach burnout. As a result of this increased endurance, you can sustain a higher level of output over a longer period of time. This is especially useful for athletes and anyone interested in fitness.

3. Contains Antioxidants

We all know about the antioxidants that you can get from eating handfuls of blueberries and other fruits, but spirulina takes it to another level.

Spirulina is an excellent antioxidant, which works with the body to reduce oxidative damage that can fuel chronic pain and inflammation.

If you suffer from chronic pain in any sense, it might be worth taking a look into how you could stand to gain from taking a regular spirulina supplement. It could provide some small measure of comfort, which would surely make it worthwhile.

4. Alleviates Allergy Symptoms

Here’s one for all of you who suffer with seasonal allergies out there. I know I do. There’s nothing worse than several months of irritation just when the weather’s getting better, and antihistamines can prove costly depending on how long you have symptoms for.

So with that in mind, wouldn’t it be nice to invest in a supplement with a natural antihistamine in it?

Taking a spirulina supplement regularly which would not only give you all the benefits listed here, but also potentially alleviate some of your allergy symptoms too.

Studies have shown that supplementing with as little as 2g a day can make a big difference, and provide relief from those irritating allergic rhinitis symptoms you have to deal with every year.

5. Helps Protect Against Cancer

While it might not be able to prevent it, spirulina has anti-cancer properties which can help your body fight the crippling disease more effectively.

It can’t hurt to take this supplement as a precaution though, since even the smallest chance of giving your body a greater chance of beating cancer should make it worthwhile.

Frequently Asked Questions About Spirulina

What is the best spirulina to buy?

We believe that Nutrex’s Pure Hawaiian Spirulina is the best supplement to buy.

Why?

Mainly because it works well. It will boost your energy levels and work to reduce inflammation in the body with its high number of antioxidants.

As a nice bonus, it is grown organically in Hawaii, and the powder is good to add into your food and drinks since it doesn’t have an awful flavour.

Is it safe to take spirulina everyday?

Despite the idea that once circulated claiming spirulina was in some way toxic (which turned out to be false), it is very much safe to take everyday in supplement form.

In fact, it goes beyond being just safe. The Dietary Supplements Information Expert Committee gave spirulina a class A rating back in 2011.

That being said, to ensure that the spirulina supplement you are taking is 100% safe and free from harmful chemicals, vet the manufacturer and check to see if what goes into the product is natural.

What should I look for in spirulina?

There are a few things you can look out for in a spirulina supplement to make sure it’s of a high quality.

First, check that the spirulina content of the supplement is at least 98%, or if it’s in powder from 100%. There should also be no preservatives or artificial ingredients present on the label.

When you have spirulina powder in front of you, you can check its colour for quality. You can tell that it’s good if it has a dark green matte shade to it, anything shiny is a bad sign.

Lastly, to determine whether the spirulina you’ve bought is good or not, you should smell it. While it has its own naturally occuring smell, spirulina shouldn’t smell offensive to the nose. If it does have a potent odour, then you know that it isn’t the highest quality.

What are the benefits of spirulina?

The benefits of spirulina are many, it is claimed to be one of the most nutritious foods available. 

By taking a regular supplement of this superfood, you will be taking on board a lot of health benefits that can be hard to find in such abundance with any other food.

They include, but aren’t limited to:

  •   Improved energy levels
  •   Reduced inflammation
  •   High Nutrient-intake
  •   Alleviated allergic rhinitis symptoms
  •   Cancer-fighting properties

The Final Word on Spirulina Supplements

Offering a wide range of benefits, and containing an extremely high level of nutrients, spirulina is one superfood that you shouldn’t live without.
