What’s So Great About Spirulina?
Spirulina isn’t just another supplement—it’s a superfood with a capital “S.” This algae, grown in warm, alkaline waters, is bursting with protein (up to 70% of its weight!), B vitamins, iron, antioxidants, and more. It’s been around for centuries—think Aztecs harvesting it from lakes—and now it’s conveniently packed into little pills for us modern folks.
People swear by it for boosting stamina, curbing hunger, and even glowing up their skin. But here’s the kicker: how many spirulina pills should I take a day to tap into all that? The answer depends on your goals, and we’re about to unpack it step-by-step.
For now, just know this: spirulina’s nutrient density makes it a game-changer, and figuring out your dose is the key to unlocking its magic. Whether you’re a newbie or a spirulina stan, there’s a sweet spot waiting for you!
How Many Tablets to Take?
If you’re new to spirulina, it’s best to start with a small amount and gradually increase your intake over time.
We recommend beginning with 1 tablet per day (assuming each tablet is 500 mg of spirulina) for the first 2 to 3 days. After that, you can add 1 more tablet every 2-3 days until you reach 4 to 10 tablets per day, depending on your specific health goals or treatment plan.
Always listen to your body and consult with a healthcare professional if you’re unsure about the right amount for you!
Can You Have Too Much Spirulina?
While spirulina is generally safe for most people, it’s important to be mindful of the amount you take. Studies suggest that doses up to 8 grams daily are safe for most individuals without causing serious side effects.
In some cases, short-term doses of 10-19 grams per day may also be safe, though more research is needed to confirm long-term safety. At higher doses, minor side effects like nausea, headache, or diarrhea can occur.
Since most studies focus on doses of 8 grams or less, it’s uncertain whether taking more provides additional benefits. It’s a good idea to start with less than 8 grams and gradually increase, depending on your needs.
One important safety tip is to ensure you buy spirulina from a trusted supplier. Wild-harvested spirulina can pose health risks if contaminated with harmful bacteria or pollutants, like microcystins, which can be toxic to the liver.
Most commercially available spirulina is grown in controlled environments, which lowers this risk. Be sure to choose a brand with quality assurance practices or third-party testing to guarantee safety.

How Can You Incorporate Spirulina Into Your Diet?
There are several easy ways to add spirulina to your diet, whether you prefer powder, tablets, or even greens powders.
Spirulina powder is a versatile option. You can mix it with water, juice, coconut water, or any beverage of your choice. It also blends smoothly into smoothies, giving them a fun, vibrant blue color.
If you’re not a fan of the taste of spirulina in drinks or smoothies, spirulina tablets are a convenient alternative. You may need to take several tablets throughout the day to reach the recommended 1-8 grams to experience its full benefits.
Another way to enjoy spirulina is through greens powders, which often contain spirulina along with other nutrient-dense ingredients like kale, spinach, and broccoli. While greens powders aren’t a substitute for a whole-food diet, they can provide additional nutrients that may be harder to get from food alone.
For example, Supergreen Tonik is a popular greens powder that not only contains spirulina (2 grams per serving) but also adaptogens like ashwagandha and rhodiola to help manage stress and improve sleep.
It also supports immunity with a blend of vitamins and minerals. Plus, Supergreen Tonik is fully transparent, so you know exactly what’s in each serving, including spirulina, greens, and other beneficial ingredients.
Incorporating spirulina into your diet is simple and offers a variety of ways to enjoy its health benefits!
How to Consume Spirulina Tablets?
To get the most out of your spirulina tablets, it’s best to spread your intake throughout the day, either before or after meals. For example, if you’re taking 4 tablets a day, you could take 2 tablets before lunch and 2 before dinner.
Since spirulina is rich in minerals, it’s also important to drink plenty of water when supplementing, as this helps prevent any digestive discomfort or issues. Staying hydrated ensures your body absorbs the nutrients effectively!
