Natural Life Bulk Spirulina Powder 1G

Bulk spirulina powder from Natural Life is sold by the gram, starting at 28 grams, so you can order a small bag for smoothies or a half kilo for the pantry.

Spirulina (Arthrospira) is a blue-green algae that people across many cultures have eaten for centuries, both as a whole food and as a dietary supplement. It is naturally vegan and instantly recognizable by its deep green color.

Why Choose Natural Life Bulk Spirulina Powder

Most spirulina online comes in fixed jars, and part of what you pay for is the jar. Ours is loose and by the gram: choose the number of grams you want, and volume discounts are applied automatically in the cart.

At 28 grams you pay $0.10 per gram. At 500 grams the price falls to under $0.04 per gram, which makes this one of the least expensive ways to keep spirulina in the kitchen.

Every batch is lab tested, and this is the same spirulina powder we stock in our retail stores.

How to Use Bulk Spirulina Powder

Spirulina is a food first. Blend it into smoothies, stir it into juice or yogurt, or work it into recipes. If you are new to it, start with about a teaspoon and adjust to taste.

Store the powder in an airtight container in a cool, dry place away from sunlight. That protects the deep green color and keeps the powder fresh far longer.

Consult your physician before starting supplemental spirulina, as it may not be for everyone.

Buying Spirulina by the Gram vs by the Jar

Volume pricing on this listing:

• 28 grams: $2.80
• 50 grams: $3.50
• 100 grams: $5.00
• 500 grams: $18.00

A fixed jar locks you into someone else’s portion math. Buying by the gram lets you try a small amount first, then scale up only if spirulina earns a permanent place in your kitchen.

We sell several botanicals the same way: ashwagandha powder and kanna powder are both available by the gram, and the full lineup lives in our Other Botanicals collection.
