spirulina powder vs tablets

When it comes to taking supplements, there are many different options. One popular supplement is spirulina, which is available in powder and tablet form. So, spirulina powder vs tablets; which is better?

If you aren’t a fan of the taste or want to avoid a mess, then tablets may be the better option. Tablets are excellent for those with trouble swallowing pills. They’re also more convenient to take on the go.

However, powder dissolves more quickly. Hence, powdered spirulina is typically more readily absorbable by the body than tablets. Plus, you don’t need to take as much powder as pills.

Continue reading to learn more about the pros and cons of each option.

Spirulina’s History

Spirulina is one of the oldest life forms on Earth. Fossil evidence indicates that it dates back over three billion years. The name “spirulina” comes from the Latin word for “spiral” or “helix,” referring to the algae’s spiral shape.

This blue-green alga has been a part of the human diet for centuries. It was a traditional food source for the Aztecs and other indigenous people of Mexico and Central America.

Spirulina Powder

The many benefits of spirulina powder make it a great way to consume this superfood. The powder is easily absorbable and has a high nutrient concentration. A small amount of powder provides a good dose of protein, vitamins, minerals, and antioxidants.

Spirulina powder is a fantastic addition to smoothies and juices. You can also mix it with foods like yogurt or oatmeal.

Spirulina Tablets

Spirulina tablets’ benefits aren’t dismissible either. Tablets are easy to take and provide a concentrated dose of nutrients. 

Spirulina tablets are an excellent option for those who don’t like the taste of spirulina powder. They’re also a good option for those who want a more convenient way to take this superfood.

Powder vs Tablets

Both types have an edge over each other. So, you should take this into account before making a decision. Check out the table below to see a comparison of the two forms of spirulina.

Differences in Absorption

Spirulina powder is finer than tablet form, making it easy to dissolve in liquids and take in smaller doses. Smaller sizes also mean powder absorbs faster. Tablets, being dense, may pass the entire system with only a tiny portion dissolving.

Keep an Eye Out for Fillers

Many supplements contain fillers, which can dilute the effectiveness of spirulina. In some cases, fillers cause severe effects.

Most tablets include fillers as these help with the compaction. Still, some providers offer tablets without fillers. If the tablets or powder don’t have a deep green or green-blue color, they likely have fillers.

Cost and Storage

While a tablespoonful of the powder is enough for a day; some users take up to 20 tablets. As such, powdered spirulina is generally more cost-effective than tablets. However, the price difference varies depending on the brand and container size.

Spirulina powder is also more versatile, as you can add it to smoothies, juices, or other recipes. Tablets are more convenient for those who want a quick and easy way to take their spirulina.

Both forms need keeping in cool, dry areas to avoid spirulina spoilage.

How to Consume Spirulina Tablets

Though there isn’t an approved dose, aim for 5 grams daily. If taking spirulina for the first time, start low and increase gradually as your body adjusts. New users can begin with 3 grams as they progress to around ten grams for maximum benefits.

Most tablets come in 500mg sizes. So, you need 20 tablets for ten grams, whereas six give you 3 grams.

Quick Ways to Consume Our Spirulina Powder

One of the powder’s main concerns is: what does spirulina taste like? This supplement has a seawater-like taste with fishy, sulfuric, and earthy undertones. However, if you don’t care for the taste, it’s an easy way to get it down.

Here are a few ideas to enjoy your spirulina powder:

  • Add to yogurt
  • Bake or cook with it
  • Add to a soup or chili
  • Sprinkle on top of a salad
  • Add to your favorite smoothie or shake
  • Add to a glass of water or other beverage (tea, coffee, and juices are excellent)

Spirulina Tablets vs Powder FAQs: The Great Powder-Tablet Debate

Which One Is Better, Spirulina Powder or Tablets?

Spirulina powder is better than tablets if you want something more straightforward for your body to absorb. Also, you can mix spirulina powder with other healthy foods and beverages, whereas spirulina tablets are typically taken alone. However, tablets are easier to carry and quick to take.

What Is the Best Form to Take Spirulina?

The best form to take spirulina is dependent on your preference. Some people prefer the powder form because it is easier to absorb and add to smoothies or other foods. Tablets are convenient for people who want to take them on the go or don’t like spirulina’s taste.

So, is spirulina powder good for you, or are tablets your thing? The choice is yours.

Are Spirulina Tablets Effective?

Spirulina tablets are effective, providing an excellent means to obtain your daily supplement dosage. In this form, you still get the rich supplies of vitamins, proteins, antioxidants, and iodine in spirulina. Although absorbed slower, spirulina tablets give a significant health boost.

What Happens if You Take Spirulina Every Day?

Many beneficial changes happen if you take spirulina every day. You get increased energy levels, improved mental clarity and focus, and enhanced detoxification.

Additionally, spirulina is a rich source of nutrients, including iron, magnesium, and vitamins B1 and B2.


Spirulina powder and tablets are both excellent sources of this nutrient-rich superfood. However, the powder is the clear winner regarding flexibility and absorption.

Tablets require more time to break down and can be challenging to digest. You can easily add the powder to smoothies, juices, and other recipes.

For those looking to incorporate spirulina into their diet, the Sunlit Superfood Powder is the way to go. You can even get yourself capsules and stuff your powder for whenever you need to travel. But if that is a hassle and you can’t spare the extra cash, quality Sunlit Organic Spirulina Tablet are good enough.

Whichever your desired form is, look for certified organic spirulina, free of fillers and binders.

Now that you’ve decided, is there anything to wait for? Grab yourself some spirulina for acne prevention and an immense health boost.
