Micro Ingredients Spirulina Powder vs. Tablets: Label and Cost Comparison

Micro Ingredients sells spirulina in two formats: a 1 lb powder pouch and a 720-tablet pouch. This source-based comparison uses current product pages, Supplement Facts images, and dated listing snapshots; it is not a hands-on review. The powder is the lower-cost option per labeled serving in the snapshots checked, while tablets provide the same stated spirulina amount in a premeasured format. Both labels list 3 g per serving.

This comparison uses the manufacturer’s product pages and Supplement Facts images, plus dated marketplace listing snapshots. We did not try the products, test their purity in a lab, or inspect a lot-specific lab report.

What each label says

The 1 lb powder page lists a serving of about one scoop (3 g) and 151 servings. Its Supplement Facts image lists 1 g protein, 6 calories, 14 mg sodium, 1 mg iron, and 1,500 mcg vitamin A (167% Daily Value). The panel names organic spirulina as the only ingredient and says the product may contain shellfish products. See the powder Supplement Facts image.

The 720-tablet page defines a serving as six tablets (3 g) and lists 120 servings per pouch. Its Supplement Facts image lists 2 g protein, 10 calories, and 3 g organic spirulina; the manufacturer says the tablets have no other ingredients. See the tablet Supplement Facts image.

The labels make the format choice easy: scoop and mix the powder, or take six tablets. Neither format lists more spirulina per serving than the other. The powder’s listed vitamin A is another label detail to consider alongside other supplements; the panel does not identify the vitamin A form.

The powder wins on listed cost per serving

The Amazon listing snapshots checked on September 27, 2026 showed $19.75 for the powder and $27.95 for the tablets. Dividing by each package’s labeled serving count works out to about 13 cents per powder serving and 23 cents per tablet serving. That’s a useful comparison if you already use powders or do not mind mixing a green powder into a drink.

This is a dated snapshot, not a current-price promise. Prices, sellers, package selection, shipping, and checkout totals can change; check those details before you buy. A pouch’s serving count also assumes you use the label serving size.

The label warning and test-report gap

Both current manufacturer Supplement Facts images carry a California warning about lead exposure. The warning does not tell us the concentration in a particular lot. Micro Ingredients says the products are third-party lab tested, but the product pages we checked do not link a batch-specific certificate of analysis that we could inspect.

If lot-specific contaminant documentation matters to you, ask the manufacturer for a report that matches the product batch before purchase. The general testing statement and marketplace popularity do not answer that question.

Which format fits your routine?

Choose the powder if you want the lower listed cost per serving, more servings in the package, and are happy to measure and mix it. Choose the tablets if avoiding a scoop is worth taking six tablets for the same labeled 3 g serving. Neither should be treated as a protein powder: the respective labels list just 1 g and 2 g of protein per serving.

The key tradeoff is convenience and listed cost, not a demonstrated health-performance difference. Read the current package label and consider the warning and testing information before deciding.
