What it actually costs

Price divided by labelled servings, from a dated listing. A serving is whatever the label calls one, which is why the studied-dose row matters more than the headline figure.

  • Yu Sleep$138 for a two-month package, down to $49 a month on the six-month. No per-serving figure: servings not recorded.

Label checks

What each label discloses, and what it leaves out. Read from the reviews, not from the marketing.

NOW Omega-3 Molecularly Distilled

  • Every active ingredient has a stated amount
  • No third-party certification

Yu Sleep

  • 6 of 7 listed ingredients have no stated amount
  • No third-party certification
  • Scored 1/10 for safety and tolerability

How this comparison is built

  • Scores are the ones already published in each review. Nothing is re-scored for the comparison, and a product leads a criterion only when it outscores the rest.
  • Doses are read from the label rows in each review and placed against the studied range on the matching ingredient page. A figure that is not printed is never estimated.
  • Costs use a dated retailer price divided by labelled servings. Prices in different currencies are never ranked against each other.
  • Only products in the same category, or ones a review names as an alternative, can be compared. Commission never changes what appears here.
