Naked Nutrition Vegan Mass Gainer — Vanilla

Consumer Reports found the highest lead result in its 2025 protein test here: 7.70 mcg lead per serving.

AvoidHighest-lead product in the CR 2025 protein-powder test — not a daily protocol pick.

Why it ranks

This replaces the older category-risk placeholder with a current product-specific result. Consumer Reports tested multiple lots of Naked Nutrition Vegan Mass Gainer, Vanilla and reported 7.70 mcg lead per 315 g serving, plus 3.45 mcg cadmium. CR said two plant-based powders contained enough lead that its experts advise against consuming them at all; Naked was the highest-lead product in that test. The brand page also carries a California lead warning, so the caution is supported by both independent testing and the product-page risk disclosure.

Highlights

  • CR 2025 product-specific data: 7.70 mcg lead per serving, the highest lead result in the set
  • Brand page discloses a California lead warning for the product
  • Exact current Vanilla packaging image verified from the Naked Nutrition product page

Caveats

  • Very large 315 g serving means exposure is not directly comparable gram-for-gram with small whey servings
  • Plant protein + high-volume mass-gainer format makes daily use a poor purity tradeoff
  • CR results are lot averages from products purchased in late 2024 / early 2025, not a live batch guarantee
  • Choose a CLP Clean Sixteen unflavored whey isolate instead if purity is the main goal
