Moringa vs Spirulina – Which One Should You Take?

I may receive a commission for purchases made through product links on this page, but I always stand by my opinions and endorsements!

So you’re ready to boost your health with supplements.

Congrats – that’s a smart decision my friend.

But there’s just one problem…

With so many different supplements to pick from, it can be a pain to find out which one is best for you.

And that’s why I started this Supplement Comparison Series.

In this series, I take two types of supplements and compare their benefits, price, side effects and more to help you decide.

Here’s whether you should take Moringa or Spirulina:

You should take Moringa if you want to reduce inflammation, cholesterol levels, blood sugar levels or increase your antioxidant intake. Whereas you should take Spirulina if you want to increase your nutrient intake, improve your endurance or reduce your blood pressure.

What is Moringa?

Moringa (Moringa Olefera) is a plant native to India that also grows in the tropics.

The fascinating thing about Moringa is that pretty much the whole plant is used for health boosting purposes.

In other words, the fruit, seeds, bark, flowers, leaves and root are all used and consumed be people.

To be clear, this is pretty rare for a plant as usually one or two parts are consumed.

(The root of Maca for example.)

What is Spirulina?

Spirulina is one of the oldest life forms on planet Earth.

It’s a cyanobacteria (blue-green algae) that helped produce the oxygen in the Earth’s atmosphere billions of years ago, which allowed the originating life forms to develop.

Today, Spirulina is used by many people for its nutrient content and its health promoting properties.


Benefits of Moringa

Moringa may reduce inflammation

Chronic inflammation is often the result of years of living an unhealthy lifestyle.

But chronic inflammation can be a killer.

In fact, many age-related diseases such as stroke, cancer, Alzheimer’s and heart disease have been linked to chronic inflammation.

So, a great way to reduce your risk of those diseases is to lower your inflammation.

Moringa is rich in compounds known as isothiocyanates, which scientists believe are potent anti-inflammatory molecules.

Moringa may help lower blood sugar levels

High blood sugar levels can lead to an energy crash, making you feel weak, agitated, and lethargic.

Quite often for me, this zap in energy results in stuffing my face with junk food, which ironically gives me high blood sugar levels and kick starts this cycle.

So to keep your energy levels in check, you ought to manage your blood sugar levels and keep them stable.

Interestingly, many studies have shown that Moringa can be effective at lowering blood sugar levels.

In a study of 30 women, 7 grams of daily Moringa for 3 months reduced fasting blood sugar levels by 13.5%.

Moringa may help lower Cholesterol

It’s widely believed that high cholesterol levels increase your risk of heart disease.

If high cholesterol levels concern you, then perhaps you should give Moringa a try as research shows it’s effective at lowering them.

Moringa is rich in Antioxidants

Free radicals can cause oxidative stress, which plays a key role in aging and many diseases.

Antioxidants are powerful molecules which can help neutralise free radicals, resulting in less oxidative stress and a younger looking you.

Moringa is packed with antioxidants, including:

  • Vitamin C
  • Quercetin
  • Beta-Carotene
  • Chlorogenic Acid

Better yet, research shows that Moringa can actually boost levels of antioxidants in the blood.

Benefits of Spirulina

Spirulina is nutrient-rich

There’s no doubt that vitamins and minerals are vital to health.

But nowadays, many peoples simply aren’t consuming enough.

An easy way to get your crucial nutrients is to supplement with Spirulina, since a tablespoon of dried Spirulina powder contains:

  • Iron: 11% of the RDA
  • Copper: 21% of the RDA
  • Vitamin B1: 11% of the RDA
  • Vitamin B2: 15% of the RDA
  • Vitamin B3: 4% of the RDA

It also contains fair amounts of magnesium, potassium, manganese, and many other vital nutrients.

So with this in mind, it’s not surprising to see people call Spirulina a “superfood”.

Spirulina may help reduce blood pressure

High blood pressure is believed to play a key role in many serious diseases like strokes, heart attacks and kidney disease.

If high blood pressure concerns you, then Spirulina may be able to help.

In a study of 36 adults, the subjects took 4.5g of Spirulina every day for 6 weeks.

And to make the study fair, the adults didn’t change their diet/lifestyle during the 6 weeks.

The results showed that the Spirulina lowered the subjects’ blood pressure as well cholesterol levels.

Spirulina may improve aerobic endurance

Despite being relatively unheard of in the fitness industry, Spirulina is a great supplement for athletes and for improving aerobic endurance.

In a study of 9 males, some took 6g of Spirulina each day for 4 weeks and the rest took a placebo.

The results showed that the Spirulina takers took longer to fatigue than the placebo takers.

Another study of 16 students had them take Spirulina each day for 3 weeks.

As part of the study they exercised on a treadmill before and after taking Spirulina.

Interestingly, the students could run for longer after taking Spirulina.

Spirulina may help against Anemia

While there are many forms of Anemia, the most common one is caused by a reduction in hemoglobin.

When this happens, you’ll likely feel tired and fatigued.

In a study of 40 adults who’ve had anemia in the last year, Spirulina supplementation increased their hemoglobin levels.
