HelloPharmacist Scorecard of Chlorella Manna by HealthForce SuperFoods

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?
  • We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Ingredient Transparency
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
Known Interaction Concern
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Chlorella.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 337 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Safety Information
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

General Statements

Chlorella is a single-celled, freshwater green algae that is one of the richest known sources of chlorophyll, which is responsible for its deep green color. The high chlorophyll content of chlorella supports oxygenation of our blood and consequent energy production in all our cells, allowing cells to release toxins more effectively. Chlorella truly shines in its ability to promote detoxification. Chlorella’s fibrous cell wall binds with heavy metals, radioactive isotopes, pesticides such as PCBs and DDT, and other toxins to help carry them out of the body.

Brand IP Statement(s)

TruGanic: Actual testing (which no other standard requires) to verify non-GMO status and 100% free from pesticides and irradiation.

Suggested/Recommended/Usage/Directions

Suggested Use: Start with 5 VeganTabs and slowly work up to 20 tablets per day, either all at once or divided.

FDA Disclaimer Statement

These statements have not been evaluated by the Food and Drug Administration. This product is not designed to diagnose, treat, cure, or prevent any disease.

Photosensitizing Drugs

Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, chlorella might reduce the clinical effects of warfarin.
