I started taking chlorella years ago because I was struggling with IBS, chronic constipation, and thinning hair. I'd tried various things with limited success, and a friend suggested chlorella. I was sceptical — it's a tiny green algae, after all — but the difference it made was enormous. My digestion settled, my bowel movements became regular for the first time in years, and over time my hair noticeably thickened. It's been part of my daily routine ever since, and it's one of the supplements I recommend most consistently to others.
Chlorella is best known as a nutritional powerhouse, but one of its most underappreciated qualities is what it does for the gut. From stimulating beneficial bacteria to cleansing the bowel and supporting cellular repair, it's one of the most comprehensive gut health supplements available. Here's how it works.
Chlorella Growth Factor & Digestive Health
Chlorella contains more chlorophyll than any other plant-based food — and it also contains something entirely unique: Chlorella Growth Factor (CGF). CGF is a group of immune-boosting compounds found only in chlorella, concentrated in its nucleus. These substances support the body at a cellular level and contribute directly to the function and integrity of the digestive system.
This matters enormously because we now know that the majority of the immune system resides in the gut. Supporting gut function is therefore one of the most impactful things you can do for your overall health — and CGF makes chlorella a particularly targeted tool for doing so.
Chlorella as a Prebiotic
One of the lesser-known facts about chlorella is that it acts as a prebiotic — stimulating the growth of beneficial bacteria in the gut. A study as far back as 1957 found that chlorella promoted the rapid growth of Lactobacillus acidophilus, a key bacteria associated with colon health and a balanced microbiome. By creating the conditions for beneficial bacteria to flourish, chlorella helps strengthen gut flora and improve the body's natural resistance to harmful pathogens. For those of us who have struggled with IBS or digestive imbalance, this prebiotic effect can be genuinely transformative.
Bowel Cleansing & Detoxification
Chlorella's high chlorophyll content helps to keep the bowel clean — supporting regular, healthy elimination and reducing the toxic load on the digestive system. Its cellulose membrane has a remarkable ability to bind to heavy metals and environmental toxins and carry them safely out of the body. Crucially, chlorella only chelates harmful toxins — it does not bind to the beneficial minerals your body needs, making it safe for regular daily use.
For anyone dealing with constipation or sluggish digestion, this cleansing action is one of the most noticeable effects — and in my experience, one of the fastest to kick in.
Tissue Repair & Bowel Regularity
Chlorella is also thought to support the repair of damaged tissue within the digestive tract, and has been associated with promoting regular bowel movements and softer stools. If you've been dealing with irregularity for a long time, the improvement can feel quite significant — as it did for me.
Chlorella & Hair Health
The connection between gut health and hair health is well established — when the gut isn't absorbing nutrients properly, hair is often one of the first places it shows. Chlorella's exceptional iron content (5x that of liver), combined with its full amino acid profile and RNA/DNA content, makes it a powerful support for hair growth and thickness. I noticed a real difference in my own hair over the months I was taking it consistently — and I've heard the same from many customers since.

The Importance of Cracked Cell Wall Chlorella
To benefit from all of the above, the chlorella you take must be bioavailable. Chlorella has a tough outer cell wall that the human body cannot break down — meaning standard chlorella passes through without releasing its nutrients. Our Cracked Cell Wall Chlorella tablets are specifically processed to break open the cell wall, ensuring full absorption of every nutrient.
Start with 3 tablets twice a day and build up gradually — your gut will thank you for it.

Frequently Asked Questions
Does chlorella help with IBS?
Many people with IBS find chlorella beneficial, thanks to its prebiotic properties and bowel-cleansing action. By stimulating the growth of beneficial gut bacteria and supporting regular elimination, chlorella can help reduce the bloating, irregularity, and discomfort associated with IBS. Results vary by individual, but consistent daily use over several weeks tends to yield the most noticeable improvement.
How long does chlorella take to work for gut health?
Most people notice improvements in digestion and bowel regularity within 2–4 weeks of consistent use. The detoxifying and prebiotic effects build gradually, so it's worth committing to a daily routine for at least a month before assessing the full benefit.
Is chlorella safe to take every day?
Yes — cracked cell wall chlorella is safe for daily use. Because it only binds to harmful toxins and heavy metals (not beneficial minerals), it won't deplete your nutrient levels. We recommend starting with a lower dose and building up gradually to allow your digestive system to adjust.
What's the best form of chlorella for digestion?
Cracked cell wall chlorella is the only form worth taking for digestive benefits. Standard chlorella has a tough outer cell wall that the human body cannot break down, meaning the nutrients pass through unabsorbed. Cracked cell wall processing ensures full bioavailability — so you actually get the prebiotic, cleansing, and repair benefits the algae has to offer.
