How we rank
We rank by cost-per-dose — price ÷ servings, normalized to the daily dose — so bottle sizes and strengths compare fairly. Prices are scraped at publication and re-checked when the catalog refreshes (see the “Prices checked” stamp above). There is no paid placement and no kickback for ordering. Full methodology · Editorial standards.
When cheapest ≠ best value
The cheapest bottle isn’t automatically the best value: a low-absorption form (magnesium oxide is the classic example) can look cheap per milligram yet deliver less of what you actually absorb. Where forms differ, compare cost per absorbed or elemental unit, not the compound weight on the label. A bigger bottle isn’t automatically cheaper per dose either — this list already ranks by cost per dose, so a larger count only wins if it truly costs less per serving. Compare Chlorella forms.
Our data on this: how much the big bottle saves per serving · the gummy tax · the form premium · the price spread.
Full ranking by cost per dose
Cost-per-serving normalizes price across bottle sizes — a 60-count and a 365-count compare fairly.

Carlyle Chlorella Tablets Organic 500 mg | 1000 Count — $0.02 per serving ($16.99 for 1000 servings), the lowest cost-per-dose chlorella in our Amazon US catalog as of September 2026.
How much does Chlorella cost per day?+
The cheapest chlorella we track works out to $0.02 per serving, against a typical $0.06 per serving across the 11 we can price per dose. Retailers and review sites list a price and a serving size but rarely divide it out — this is what a day actually costs, as of September 2026.
What is the typical cost per dose for Chlorella?+
About $0.06 per serving across the 11 chlorella products we can price per dose (combination products are left out — their single label dose belongs to whichever ingredient the product is built around) — the cheapest we track is $0.02 per serving, with most falling between $0.05 and $0.16.
What is the highest-quality Chlorella supplement?+
None of the 9 chlorella brands ranked here carry a USP, NSF or Informed-Sport certification we could confirm in the public registries as of September 2026. That does not make them bad — most supplement brands never submit to voluntary testing — but if independent verification matters to you, check the registries linked below before buying.
Which Chlorella brands are third-party tested?+
None of the 9 brands on this page appear in the USP, NSF or Informed-Sport public registries. We never count a "lab tested" claim printed on a label as third-party testing — only an entry in the certifier's own registry.
Which Chlorella is the top rated?+
We don't republish marketplace star ratings — they belong to the retailer, they move constantly, and a 4.6 average tells you nothing about what is in the capsule. The two things you can verify are what a dose costs and whether an independent lab checked the label. On this page the best value is Carlyle Chlorella Tablets Organic 500 mg | 1000 Count at $0.02 per serving; no brand here holds a certification we could verify in a public registry.
What dose of Chlorella do these supplements come in?+
The chlorella products we track range from 200mg to 1000mg per serving. We rank by cost per serving so you can compare value across strengths — check the label for the dose that suits you.
Independent testing
Independent third-party testing is a voluntary check of a product's identity, potency and contaminants by an outside lab. It's a quality signal, not a value or efficacy claim. Confirm any brand's current status on the official registries:
Testing status is self-reported by the brand or drawn from public certification and may change — always verify on the official registry before purchase.
