Powder and ready-to-drink protein gross sales have exploded, attaining over US$32 billion globally from 2024 to 2025. More and more, customers are using these protein sources daily.
A untouched find out about by way of Client Experiences, revealed on Oct. 14, 2025, claims that some such protein merchandise contain dangerously high levels of lead, in addition to alternative weighty metals corresponding to cadmium and arsenic. At prime ranges, those ingredients have severe, well-documented health risks.
I’m a clinical pharmacologist who has evaluated the weighty steel content material of baby food, calcium supplements and kratom products. Manage and alternative weighty metals occur naturally in soil and water, so reaching zero-level publicity can be unimaginable. Moreover, the extent of supremacy publicity that Client Experiences deems shield is considerably less than the ones all set by way of the Meals and Drug Management.
Alternatively, without reference to the security cutoff, the find out about does display that a couple of merchandise are handing over a concerningly prime dose of weighty metals consistent with serving.
How Client Experiences did the find out about
The untouched find out about assessed 23 powder and ready-to-drink protein merchandise from prevalent manufacturers by way of sending 3 samples of each and every product to an sovereign industrial laboratory.
Client Experiences regarded as anything else over 0.5 micrograms per day from any unmarried supply to be above really useful most supremacy ranges. That quantity comes from the California Office of Environmental Health Hazard Assessment, which established really useful most ranges for quite a few ingredients that would reason most cancers or fetal hurt.
It’s considerably extra conservative than the security usual for supremacy publicity impaired by way of the FDA for medicine and dietary supplements. The discrepancy is pushed by way of Client Experiences’ aspirational targets of very low publicity as opposed to the extra practical however actionable necessities from the FDA.
In line with the FDA, the prohibit for the quantity of supremacy that an individual will have to eat from any unmarried nutritional complement product is 5 micrograms per day. That quantity is 10 instances upper than the Client Record prohibit.
The FDA has every other usual for the entire day by day quantity of supremacy an individual can safely eat from meals, medicine and dietary supplements blended. This quantity, referred to as the Interim Reference Level, or IRL, for lead is in response to concentrations of supremacy within the blood which can be related to unfavourable condition results in numerous populations.
For society who may just grow to be pregnant, that point is 8.8 micrograms consistent with year, and for kids it’s 2.2 micrograms consistent with year. For everybody else, it’s 12.5 micrograms consistent with year. Each meals, drug and nutritional complement that comprises supremacy contributes to the entire day by day publicity, which will have to be not up to this quantity.

What the record discovered
The nonprofit advocacy team discovered that 16 of the 23 merchandise it examined exceeded 0.5 micrograms, the extent of supremacy in a typical serving that the group deems shield.
4 of the 23 merchandise exceeded 2.2 micrograms, the FDA’s cutoff for the entire day by day quantity of supremacy kids will have to eat. Two merchandise contained 72% and 88%, respectively, of the entire day by day quantity of supremacy that the FDA deems shield for pregnant ladies.
As well as, Client Experiences discovered that two of the 23 merchandise delivered greater than what it considers a shield quantity of cadmium consistent with serving, and one had extra arsenic than was once really useful.
The group’s protection cutoff for cadmium is 4.1 micrograms consistent with year, and for arsenic it’s 7 micrograms consistent with year. Those numbers align moderately carefully with the FDA’s really useful publicity prohibit for cadmium and arsenic from a single product. For cadmium, the FDA’s prohibit is about at 5 micrograms consistent with year for a given nutritional complement product and 15 micrograms consistent with year for arsenic.
The find out about discovered that the supply of protein was once key: Plant-derived protein merchandise had 9 instances the supremacy present in dairy proteins like whey, and two times up to beef-based protein.
The place are those weighty metals coming from?
Manage and alternative weighty metals are found in prime quantities in volcanic rock, which comes from molten rock referred to as magma underneath the Earth’s floor. When volcanic rock is eroded, the weighty metals contaminate the native ground and H2O provide. What’s extra, some abbreviate crops are particularly environment friendly at extracting heavy metals from the ground and striking them within the portions of the crops that buyers ingest.
Fossil fuels, which come from deep throughout the Earth, additionally billow heavy metals into the air when they are burned. Those ingredients after govern out into the ground and H2O. In spite of everything, some fertilizers, herbicides and pesticides additionally comprise weighty metals that may additional contaminate ground and native H2O.
Prime ranges of weighty metals had been present in plant-based protein powder, spices like cinnamon, dark chocolate, root greens like carrots and sweet potatoes, rice, legumes such as pea pods and lots of herbal supplements.

Must customers be involved? And what can they do?
Every so often exceeding the day by day really useful weighty steel doses is not likely to lead to severe condition problems.
Repeated, weighty publicity to weighty metals could cause hurt, then again. Once they accumulate in the blood, these substances can delay or impair mental functioning, injury nerves, soften bones and raise blood pressure – which in flip will increase the danger of strokes and middle assaults. Big metals too can build up the risk of developing cancer.
It’s noteceable to notice that all of the merchandise Client Experiences flagged have supremacy ranges considerably less than the utmost day by day publicity ranges established by way of the FDA.
Shoppers can prohibit publicity by way of opting for dairy- or animal-based resources of protein merchandise, since they normally looked as if it would have much less weighty steel contamination than plant-based ones. Alternatively, some plant-based protein merchandise within the find out about didn’t have prime ranges of weighty metals. Big steel ranges range widely in the environment, so the consequences from the Client Experiences find out about display a snapshot in future. They will not be constantly correct throughout batches if, as an example, a producer adjustments the supply of its uncooked substances.
For protein merchandise that do display an extremely prime weighty steel content material, the use of them extra sporadically, instead than day by day, can shed publicity. Research counsel that organic plant-based products normally handover much less weighty steel content material than historically farmed ones.
In spite of everything, the Client Experiences find out about leisurely weighty metals in one serving of protein merchandise, so it’s useful to grasp what constitutes a serving for particular merchandise and to keep away from sharply expanding day by day intake.
General, the broad variation in supremacy ranges throughout other protein powders and ready-made protein merchandise highlights the will for producers to tighten product trying out and just right production practices.
