A popular protein powder brand is facing some heavy metal backlash.

Costco was slammed with a class-action lawsuit last week, accusing the retailer of selling Orgain protein powder that allegedly contains high levels of toxic heavy metals while marketing it as “clean” nutrition. The lawsuit claims the advertising was misleading.

According to the complaint, independent laboratory testing detected heavy metals in Orgain’s Vanilla Bean and Chocolate Fudge protein powders. And Orgain isn’t the only protein brand that has faced scrutiny.

A Consumer Reports investigation found that more than two-thirds of the 23 protein powders and ready-to-drink shakes it tested contained more lead than food safety experts said would be safe to consume in a day. Some levels were more than 10-times higher than the suggested limit.

The news has prompted many shoppers to look for protein powder brands with more rigorous testing and stronger quality standards. One option gaining attention is Needed., whose newer, cleaner collagen protein formula has racked up thousands of sales on Amazon.

Needed. says every batch is independently third-party tested for purity and safety and meets California Proposition 65 limits — one of the industry’s most stringent testing standards for banned substances and contaminants.

The hydrolyzed collagen protein formula retails for almost $50 on Amazon, though shoppers can save 17% when they subscribe.

With 14 grams of protein per serving, Needed. still offers a solid protein boost — plus the added benefits of collagen. According to the brand, the collagen-based formula also helps support longer, healthier hair, skin and nails while promoting the strength and structure of connective tissues.

Reviewers also say it’s tasteless and blends easily into smoothies, coffee and other drinks, making it simple to work into your routine. Beyond that, many customers appreciate that Needed. has been transparent about its sourcing and testing process.

“For heavy metals specifically, every single Needed product batch is tested at an accredited, third-party lab to ensure levels are below California Proposition 65 limits before we release it to our customers,” the brand writes on its website.

According to shoppers, the “formula is clean and minimal,” and many reviewers say they’ve seen noticeable results with consistent use. Each container offers 30 servings for a one-month supply.
