Curcumin500 mg

What to check on the label

  • Whether the milligrams describe the whole extract or the standardised compound (for example '500 mg turmeric extract' versus '475 mg curcuminoids').
  • Delivery wording such as liposomal or phytosome changes the carrier, not the labelled amount.
  • For glutathione and sulforaphane, check whether the label lists the compound itself or a precursor (glucoraphanin, NAC).

Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.

Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Why this scored this way

This Jarrow Formulas Jarrow Formulas Curcumin Phytosome (Meriva), 500 mg scores 6.8, making it a mid-tier product with both strengths and weaknesses. It delivers 500mg of Curcumin, inside the studied range of 500–2000mg with grade B evidence (promising human data, not yet comprehensive). The quality transparency (6.0) is limited by the lack of third-party testing.

What drives the score up

  • Dose-evidence score of 7.2 shows decent alignment with trial doses.
  • Curcumin is dosed at the full research level with grade B evidence (promising human data, not yet comprehensive).

What drags it down

  • No third-party testing, which caps the quality transparency.
  • Quality transparency of 6.0 is below the site average.

Why you'd choose it

  • You want a reasonably priced antioxidant product.
  • You want Curcumin from a Jarrow Formulas product.
  • You want doses that align with published research.

Why you might skip it

  • You want third-party verified purity.
  • You want a product with a publicly available CoA.
  • You want stronger transparency (this scores 6.0).

Evidence

Research behind this product

The studies that established the trial dose and evidence grade for each active ingredient in this product. Click through to read the original paper.

Important to know
CurcuminProducts with just 'turmeric extract' and no branded delivery system are not bioavailable. Ask for the specific bioavailability system.

Editorial notes

Uses the well-studied Meriva phytosome technology for better absorption than plain curcumin, but delivers only 90mg actual curcuminoids per capsule, a bioavailability-for-dose tradeoff versus Curcumin 95.
