How To Choose the Best Chlorella Supplement

With the number of Chlorella supplements available, it might be also a bit exhausting to find the best one that fits your needs. So here are some of the important factors we considered in this list. 

Ingredients and Processing

Some chlorella supplements in the market also include artificial additives. These preservatives are non-organic and may also affect the purity of chlorella. Moreover, as with any other supplement, it’s always wise to choose the ones with organic ingredients.

Also, the processing of chlorella is a bit tricky. Its rigid cell wall can’t be digested by the human body, so manufacturers break down this cell wall for us to reap its benefits. The brand also needs to disclose what method was used. The common methods are fermentation as well as centrifugation.

Supplement Type 

Chlorella supplements also come in capsules, tablets, and powder form. Therefore we’ve made sure to consider these different forms in our list with their pros and cons to help you pick what works for you.

Brand Reputation

As with any other product, buying from a trusted brand that will also provide good value for money is important. Moreover, nothing beats a good reputation for producing high-quality products for years. So we also made sure that all the products on our list are from reputable companies and the products are worth your hard-earned money.


Chlorella is generally recognized as safe, and few side effects have been reported.[1] Moreover, in terms of dosage, some studies found benefits with 1.2 grams per day. Other studies also used up to 5-10 grams per day and considered it safe and beneficial.[2][3] Hence, most supplements recommend a dosage of about 2-3 grams per day.

However, if you are nursing, pregnant, taking medication, or have any medical condition, you should consult your physician before taking this product.


What Are the Side Effects of Taking Chlorella?

Although chlorella supplements are generally considered safe for most people, a few reported side effects include nausea and stomach discomfort.

What Is the Best Form of Chlorella To Take?

The powder form might also be a good choice for those who prefer to consume larger amounts. However, tablets can also be a more convenient option because they are easy to take and usually small in size. Hence, the answer to this will depend on what works for you. 

Is It Safe To Take Chlorella Every Day?

In the studies mentioned earlier, chlorella was taken daily. Supplement brands also recommend taking it every day to optimize its beneficial effects. However, make sure to follow the recommended dosage and consult your doctor if you experience any side effects.

Bottom Line

In conclusion, chlorella is considered a superfood because of its wide range of nutritional benefits. It’s also a good source of essential vitamins, minerals, and antioxidants and can be taken conveniently in the form of tablets, capsules, or powder. Chlorella supplements can indeed provide various nutrients for your body with consistency and the right dosage.
