- 57.8% of products fall below the fairy-dust threshold (360 mg, 20% of the studied low dose).
- 61.1% of products don't disclose an amount because Chlorella is declared inside a proprietary blend.

Search interest over time
How often people search for chlorella on Google, US only, the last 5 years. This is public interest, not DSLD label data — a spike here doesn't necessarily line up with anything on this page, and Google's own index (100 = that term's peak popularity in the chosen window) is relative, not an absolute search-volume count.

Forms explained
Label discloses only "Chlorella" with no cell-wall treatment or extract specified.
Cell-wall disruption is the stated rationale (the intact wall is hard to digest), but no human digestibility or absorption comparison of cracked vs intact chlorella was verified in this pass; PubMed searches returned only a laboratory cell-disruption protocol and an in vitro lutein-uptake study.
Source: uncertain -- needs review (no human comparative study located)
Extract mass is not comparable with whole-cell powder mass; recorded without a dose.
A protein-enriched ingredient (Chlorella protothecoides is not the species used in the cited trials), not whole-cell chlorella; recorded without a dose.
Reference values
- RDA (adult): not established — Green microalga used as a food/supplement; not an essential nutrient, no RDA/AI exists.
- Tolerable Upper Intake Level (adult): not established — Not established. No safety source was fetched for this entry, so no tolerability statement is made here.
- Studied clinical dose range: 1800–5000 mg
- High end: Kwak JH et al. 2012, Nutr J 11:53, PMID 22849818 -- 8-week double-blind RCT (Chlorella n=23, placebo n=28), 5 g/day as tablets; interferon-gamma and IL-1beta increased more than placebo and natural-killer-cell activity rose. Same 5 g/day in Kim S et al. 2016, Nutr J 15:54, PMID 27177615 (n=34, 4-week dietary-cholesterol challenge; smaller rise in total and LDL cholesterol than placebo). Low end (a chlorella EXTRACT, not whole-cell powder): Panahi Y et al. 2015, Complement Ther Med 23(4):598-602, PMID 26275653 -- Chlorella vulgaris extract 1800 mg/day (n=42) added to antidepressant therapy for 6 weeks vs continued therapy alone. Meta-analysis context: Fallah AA et al. 2018, Clin Nutr 37(6 Pt A):1892-1901, PMID 29037431 -- 19 RCTs/797 subjects; subgroup with doses above 4 g/day showed significant total/LDL cholesterol and blood-pressure reductions.
- Note: Unit basis: mg of chlorella as declared (whole-cell/"cracked cell wall" powder or tablets; extract rows are separated in forms and carry no dose). The 1800 mg low end is an extract and the whole-cell tablet trials cited here used 5 g/day, so the effective whole-cell range is narrower than the stated low-high span. "Chlorella protein" and Chlorella protothecoides algal-protein rows are protein isolates, not the whole alga, and are recorded without a dose.
