Chlorella is a single-celled green algae sold as a powder or tablet. People take it for nutrients (protein, iron, some B vitamins), for detox support, and to boost general health. Here you’ll find quick, practical advice on what chlorella might do, how to use it, and when to be careful.
Chlorella packs nutrients: about 50–60% protein by dry weight, plus chlorophyll, iron, and trace vitamins. Small clinical trials show modest benefits—some users see lower LDL cholesterol and slight blood pressure drops. Other studies report antioxidant and immune-support effects, but results vary and trials are often small.
People also use chlorella for toxin binding. Animal and limited human studies suggest it may help bind heavy metals and speed their removal, which is why some detox programs include it. Remember: these effects are supportive, not a cure, and depend on product quality and dose.
Quality matters. Look for products that state “broken cell wall” or “cracked cell wall” — whole chlorella is hard to digest, and processing makes nutrients available. Choose brands with third-party testing for contaminants (heavy metals, microcystins) and clear sourcing info. Organic certification helps but isn’t foolproof.
Forms: tablets are easiest for daily use; powders work well in smoothies or mixed into juice. Start small—try 500 mg once daily for a week, then increase. A common effective range is 2–3 grams per day; some people take up to 5–6 grams. Higher doses are used in research but can raise side effects.
Timing: take with food. If you want the iron benefit, pair chlorella with vitamin C (a squeeze of lemon or orange) to improve absorption.
Watch for side effects and interactions. Mild GI upset, gas, and diarrhea are the most common issues, especially at first. Allergic reactions can occur, particularly in people with seafood or iodine sensitivities. Chlorella contains vitamin K, so it can affect blood thinners like warfarin. Because it can stimulate the immune system, talk to your doctor before using it if you have autoimmune disease or are on immunosuppressants. Pregnant or breastfeeding? Check with your clinician—evidence is limited.
Practical checklist: choose a tested brand, start low and build up, take with food and vitamin C if iron is a goal, stop if you get an allergic reaction, and discuss use with your healthcare provider if you take medications or have chronic conditions. If you just want a nutrient boost and don’t expect miracle results, chlorella can be a useful, plant-based addition to your routine.
Questions about a specific product or your dose? Ask your pharmacist or clinician — they can recommend a safe brand and a dose that fits your health plan.
