Chlorella & Spirulina


Q1: What are the differences between Spirulina and Chlorella? Which is more suitable for me?

A: The basic nutrient level such as proteins, carbohydrates, fat are similar, but they vary by the composition of vitamins, minerals, trace elements, and phytochemicals.   




Cell Shape


spring-like spiral



Phycocyanin, chlorophyll

Exterior appearance


Dark Green

Provided nutrients

Dietary fiber, iron, calcium, chlorophyll, and lutein

GLA, folic acid, protein, β-carotene-based

Special nutrients

Chlorophyll, Chlorella Growth Factor (C.G.F)

Phycocyanin, Spirulina Growth Factor (S.G.F)

Chlorella can be used for detoxing heavy metals or to remove excess water in the body. Spirulina can be used as an anti-oxidant or a supplement to replenish proteins and gamma-linolenic acid for better immune support from damages. The best method would be to take both for a full spectrum of nutrition needed by our bodies.


Q2: What do I buy organic microalgae? 

A: FEBICO Organic Chlorella and Spirulina have been certified by German Naturland organization every year since 2001 (13 consecutive years!), along with USDA Organic Certification, Taiwan & China Organic Certification to guarantee there are no synthetic fertilizers, chemicals, herbicides, pesticide used or contaminated during the production & packaging process.

FEBICO organic products are under the most stringent environmental and production examination and guaranteed its organic property, responsible for our mother nature. Organic culturing requires much more time and manpower, in return for natural nutrients that accumulated within the algae.

Taking chlorella as an example, it easily uptakes its surrounding particles and if any herbicide or unnatural substances are used, you maybe consume those unsafe chlorella and cause chronic damage to your health. Therefore, you should buy brands with organic certifications or from manufacturer like FEBICO that have quality reassured by numerous organization routinely. 


Q3: Why does Chlorella need to undergo broken cell wall process?

A: Chlorella has a very thick and strong cell wall, when the cell wall is not cracked, it is very difficult to be digested. FEBICO's very own uniquely patented “Low-Pressure Flash Expansion Technique” explodes the cell walls under certain pressures, which increases the digestive rate to more than 80%, twice amount compared to other chlorella brands in the market. This technique has also obtained a Taiwanese patent (Patent number 183428).


Q4: How do I consume Spirulina & Chlorella at the same time, and what is the recommended dosage for different tablet sizes?

A:Spirulina has its unique immune-stimulatory substances like GLA, phycocyanin and sulfuric-carbohydrate to protect you from bacteria and virus during day time. Its rich nutrient profile gives you better energy at work. On the other hand, chlorella has rich dietary fiber and it can promote bowel movement at night during sleep, so you can go to bathroom easily in the next morning. Besides, its GABA amino acids can stabilize your nervous system and aids you with sleep.

A: Spirulina contains Spirulina Growth Factor(S.G.F) and Chlorella contains Chlorella Growth Factor (C.G.F), these can help with the absorption of nutrients. Therefore, Chlorella and Spirulina can be taken with other nutritional supplements. Multivitamins are recommended to be taken once every three days.

Coffee or tea are not recommended to be taken at the same time as they are considered pungent foods. To avoid damaging of the nutrients, we recommend taking Chlorella and Spirulina with water.

Q11: Can pregnant or lactating women take Chlorella and Spirulina? What is the recommended dosage?

A: Pregnant women mostly lack of folic acid, calcium, iron, vitamin A, vitamin B group and other nutrients. The nutrients of Chlorella and Spirulina are the perfect whole food to supplement them with those insufficient nutrition. Chlorella growth factor found in Chlorella is perfect for children and pregnant women, which makes chlorella an affordable and useful product. The recommended dosage per day is 3 grams, and can be taken partially.


Q12: Is Chlorella and Spirulina the same as the seaweed and kelp we eat normally?

A: Seaweed, kelp, and agar are all types of algae, they are different in size and shape and can be seen by the naked eye and therefore are considered macroalgae or large algae. Large algae can often be found along the coastline but are different to Chlorella and Spirulina. Chlorella and Spirulina need a clean environment with sufficient sunlight and clean water to grow. Apart from the difference in shape and growing environment, Chlorella and Spirulina also contain large amounts of nutrition of which cannot be matched by larger algae. Unlike larger algae, Chlorella and Spirulina do not contain iodine, therefore hyperthyroidism sufferers can also consume Chlorella and Spirulina at recommended dosages.


Q13: Can sufferers of hyperthyroidism and kidney diseases also use Chlorella and Spirulina?

A: Unlike algae cultivated from seawater, Chlorella and Spirulina contain no iodine, therefore it is safe for patients suffering from hyperthyroidism. Patients that are suffering from major diseases are recommended to see and follow a doctor's directions for recommended dosage.

Q16: Why may constipation occur when taking chlorella?

A: Constipation normally occurs when there is insufficient liquids in the body. Chlorella is rich in dietary fibers and our bodies cannot digest and absorb these materials.
