If the word “microalgae” has you imagining something slimy pulled out of a pond, don’t fret! You don’t need to scoop this stuff up yourself to reap the incredible health benefits.

Health-conscious buyers can use spirulina supplements to help their bodies achieve peak performance. It’s easy and convenient to add spirulina powder to smoothies, dips, and even baked goods, turning your favorite everyday foods into superfoods.

While spirulina tablets are available, using a powdered spirulina supplement will help you take in maximum nutrients without any added fillers or chemicals.

Your body wants spirulina! The power and potency of spirulina can’t be overstated – spirulina is an incredible superfood!

Let’s dive deeper into each of the many benefits of this natural gift.

✓  It’s a Good Source of Protein

The best and probably most surprisinvg benefit of spirulina is the fact that it’s a top-notch source of complete vegan protein.

This humble algae contains anywhere from 55-70% protein, which is more than soybeans and cooked meats. Consider that even omnivores’ golden child, cooked beef, only maxes out at a modest 40.6% protein. A few teaspoons of spirulina in your meal is a good way to sneak in some extra protein – as well as plenty of vitamins and minerals – without a lot of calories or volume.

Maybe instead of asking “where’s the beef”, the phrase should be “where’s the spirulina”?

✓  It Protects Against Cancer

We know that the more vibrant a whole foods’ color, the more efficient it tends to be at protecting us from cancer. Just think about beautiful berries and dark, leafy greens.

Spirulina is also a powerful cancer fighter. Phycocyanin, the biliprotein that gives spirulina its beautiful blue color, has been shown to inhibit cancer-colony formation. The high levels of chlorophyll also show evidence of cancer prevention.

If cancer runs in your family, or you simply want to take out some extra insurance, consider conscripting a spirulina supplement to help prevent cancer cells from running amok in your body.

✓  It Reduces Cholesterol

Spirulina is a perfect way to lower your cholesterol and blood pressure the natural way, without having to deal with side effects from prescription medication.

A recent study found that 1g of spirulina per day for 90 days decreased triglycerides by 16.3%, total cholesterol by 8.9%, LDL cholesterol by 10.1%, and total cholesterol to HDL ratio by 11.5%.

Just a gram of spirulina per day can lower total and LDL cholesterol and increase the amount of “good” cholesterol – all without ever needing to pop a pill!

✓  It Boosts Energy

The iron in spirulina can provide a big boost in energy – no need to reach for that 2 pm cup of coffee! The best part is that spirulina provides natural iron without any side effects of traditional iron supplements.

By providing a boost of iron and reducing oxidative stress with the help of antioxidants, spirulina helps give a surge of energy. Its iron and nutrient content makes it an ideal energy booster for menstruating or pregnant women, or the elderly.

Even if you’re none of those things, many people experience an energy boost from this food. For best results, take your spirulina in the morning or afternoon instead of in the evening.

✓  It Helps with Weight Loss

Watching your waistline? Add spirulina to your supplement stack, and your body will thank you!

There are many reasons Spirulina aids in weight loss goals. The first reason is that Spirulina is extremely high in nutrients. This can help reduce feelings of hunger by providing your body with the nutrition it’s craving. The protein content of spirulina can also keep you satiated, causing you to eat less.

The fatty acids in Spirulina also help regulate blood sugar and insulin, which in turn minimizes gorging on carbs and consumption of excess calories.

Make losing weight a little easier, with nothing more than a sprinkle of spirulina!

How Does Spirulina Taste?

There’s no getting around it – spirulina can be an acquired taste. Mainly because it must be consumed in its raw state as cooking or brewing the spirulina can affect the potency of the nutrients.

There are ways to make this superfood a little easier on the palate. Many health gurus swear by mixing a little spirulina into a smoothie or juice – the strong tastes of the fruits and vegetables in the drink will help mask the taste of the spirulina. It goes very well with orange, carrot, and celery juice.

For the utilitarian consumer, you can easily take powdered spirulina as a shot. Simply mix the spirulina with some water, toss it back, and chase with fresh water or your favorite juice.

Is it a delicacy? No. But the health benefits of spirulina are worth a few seconds of unpleasantness. Ultimately, the flavor is easily masked under the taste of your favorite fruits or vegetables.

What to Look for in a Spirulina Supplement

1 – Is it Organic?

To make sure you’re getting the best quality nutrients into your body, you’ll want to opt for a brand that’s grown completely organically.

In addition to keeping harsh chemicals and pesticides out of your food and out of your body, it’s especially important to buy organic spirulina because of where it grows. As it’s a microalgae, Spirulina grows in water, and water can be subject to excessive amounts of pollution, toxins, and heavy metals. Whatever the water contains will seep into the spirulina.

By consuming a spirulina that was grown entirely organically, you can be sure that you won’t be consuming these harmful chemicals and heavy metals.

2 – Country of Origin

Where your spirulina comes from can also affect how healthy that supplement is. When possible, you may want to avoid spirulina supplements that come from China and Japan.

Because Chinese supplements do not go through the same rigorous regulation process as supplements in North America, Chinese supplements have been found to contain high levels of lead, arsenic, and mercury.

If you want to choose a supplement that comes from China, ensure it is tested for heavy metals first. Saving a few dollars simply isn’t worth sacrificing your health over!

You should also pay particular attention to where Japanese spirulina is grown. After the Fukushima nuclear disaster, spirulina grown in the area may contain high levels of radiation and should be tested/clearly labeled before consumption.
