Curcumin400 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 Nootropics Depot Longvida Optimized Curcumin Capsules scores 7.0, making it a mid-tier product with both strengths and weaknesses. It delivers 400mg of Curcumin, 80% of the studied range low edge (500mg) with grade B evidence (promising human data, not yet comprehensive). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $1.92/day it's among the more expensive options in Antioxidant.

What drives the score up

  • Dose-evidence score of 6.3 shows decent alignment with trial doses.
  • Quality transparency of 9.0: tested by independent lab with a public lab certificate.
  • Community score of 8.8 with positive consumer feedback.

What drags it down

  • Curcumin (400.0mg is 40% of the 1000mg trial dose) is significantly under-dosed.
  • At $1.92/day it's on the expensive side.

Why you'd choose it

  • You want Curcumin from a Nootropics Depot product.
  • You prioritise tested by independent lab products with public lab certificates.

Why you might skip it

  • You need a full trial dose of curcumin (this product under-doses it).
  • You want a cheaper option (this is $1.92/day).
