Chlorella is one of those supplements that genuinely deserves its superfood status. It's been part of my daily routine for years — and once you understand what it actually does, it's easy to see why. Here are the five most important things to know about chlorella.
1. What Chlorella Actually Is
Chlorella is a tiny single-celled freshwater algae that has been on this planet for over 3 billion years — making it one of the oldest, simplest, and most potent forms of nutrition in existence. Despite its microscopic size (comparable to a human blood cell), it reproduces at a remarkable rate, completing a full growth cycle in just 24 hours. It is one of the most basic forms of life, yet nutritionally one of the most complex.
2. Why Cracked Cell Wall Chlorella Matters
This is the detail that most people miss — and it's crucial. Chlorella has a tough outer cell wall that the human body simply cannot break down on its own. Without processing, the nutrients pass straight through you. That's why our Cracked Cell Wall Chlorella tablets use a specific technique to break open the cell wall, making all those nutrients fully bioavailable and easy for your body to absorb.
3. Its Nutritional Profile Is Extraordinary
Chlorella is one of the most nutrient-dense foods on earth. It contains all 9 essential amino acids, omega 3, 6, and 9 fatty acids, and is one of the richest plant sources of chlorophyll available. To put its nutrient density in perspective:
- 9x the beta carotene of carrots
- 5x the iron of liver
- 2x the protein of beef
- 2x the vitamin K of kale
- 2x the calcium of milk
- 8x the RNA of sardines
- 6x the lutein of kale
It's a genuinely complete food — and in tablet form, one of the most convenient ways to get a broad spectrum of nutrients in a single daily habit.
4. It's Exceptional for Gut Health
Chlorella supports the gut in several important ways. It stimulates the growth of beneficial bacteria, helping to create a healthy microbiome environment. Its high chlorophyll content also helps to cleanse the bowel and support liver function. For anyone dealing with bloating, sluggish digestion, or simply wanting to support their gut health long-term, chlorella is a valuable addition to the daily routine.

5. It Supports Healthy Ageing at a Cellular Level
Chlorella is one of the richest known sources of RNA and DNA — compounds that support healthy cell renewal and repair. As we age, cellular repair becomes increasingly important, and chlorella's exceptional RNA and DNA content makes it one of the most targeted supplements available for healthy ageing from the inside out. It also has well-documented detoxifying properties, binding to heavy metals and toxins in the body and helping to carry them out. The gut-hair connection is also worth noting — read more in how chlorella transformed my hair.
How to Take Chlorella
One of the things I love about chlorella is that it's one of the few supplements you can gradually increase over time. I recommend starting with 3 tablets twice a day and building up slowly — you can work your way up to a maximum of 20 tablets per day as your body adjusts. Our tablets come in a beautiful Miron glass jar (which protects the nutrients from light degradation) or a refill pouch for a more sustainable option.

Frequently Asked Questions
What does chlorella do for the body?
Chlorella supports the body across multiple systems — it feeds beneficial gut bacteria, detoxifies heavy metals and environmental toxins, supports cellular repair via its RNA and DNA content, and provides a broad spectrum of essential nutrients including amino acids, iron, chlorophyll, and omega fatty acids. It's one of the few supplements that genuinely earns the label "superfood".
How much chlorella should I take daily?
We recommend starting with 3 tablets twice a day (6 tablets total) and building up gradually as your body adjusts. You can increase up to a maximum of 20 tablets per day over time. Starting slowly helps your digestive system adapt, particularly if you're new to algae-based supplements.
Is chlorella good for gut health?
Yes — chlorella acts as a prebiotic, stimulating the growth of beneficial bacteria like Lactobacillus acidophilus. Its chlorophyll content also supports bowel cleansing and regular elimination. Many people notice improvements in bloating and digestion within a few weeks of consistent use.
What's the difference between chlorella and spirulina?
Both are algae-based superfoods, but they have different strengths. Chlorella is particularly noted for its detoxifying properties, gut health benefits, and CGF (Chlorella Growth Factor), which supports cellular repair. Spirulina tends to be higher in protein and is often used for energy and endurance. Many people take both. See our Wheatgrass vs Chlorella article for a deeper comparison.
