Spirulina & Chlorella

Spirulina and chlorella are nutrient-dense microalgae and two of the most popular green superfoods. Spirulina is a blue-green algae rich in protein, B vitamins, iron and the antioxidant phycocyanin. Chlorella is a green algae rich in chlorophyll and fiber, and it is known for binding to compounds in the gut to support the body's natural detoxification.

How to Choose Spirulina or Chlorella

• Spirulina: Best for protein, B vitamins and antioxidants. Organic Spirulina by NOW is our top seller.
• Chlorella: Best for chlorophyll and detox support. Look for broken or cracked cell wall chlorella, which your body can digest. Sun Chlorella is a popular pick.
• Tablets vs. powder: Tablets are convenient. Powders blend into smoothies but have a strong, grassy taste.
• Organic and tested: Choose organic products that are tested for purity and heavy metals.
• Greens blends: For a broader mix of plant nutrients, see greens.

Start with a small amount and increase slowly, since algae can cause mild digestive changes at first. Take chlorella away from medications by a couple of hours. If you take blood thinners, check with your practitioner, since algae contain vitamin K. See also detoxification.
