Protein powders and shakes contain high amounts of lead, new report says – a pharmacologist explains the data
A recent Consumer Reports study reveals that many protein powders contain hazardous levels of lead and other heavy metals, raising health concerns. Most plant-based products had higher contamination than animal-based ones. Consumers are urged to choose cautiously and regulate their intake.
Protein powders and shakes contain high amounts of lead, new report says – a pharmacologist explains the data
C. Michael White, University of Connecticut
Powder and ready-to-drink protein sales have exploded, reaching over US$32 billion globally from 2024 to 2025. Increasingly, consumers are using these protein sources daily.
A new study by Consumer Reports, published on Oct. 14, 2025, claims that some such protein products contain dangerously high levels of lead, as well as other heavy metals such as cadmium and arsenic. At high levels, these substances have serious, well-documented health risks.
I am a clinical pharmacologist who has evaluated the heavy metal content of baby food, calcium supplements and kratom products. Lead and other heavy metals occur naturally in soil and water, so achieving zero-level exposure would be impossible. Additionally, the level of lead exposure that Consumer Reports deems safe is significantly lower than those set by the Food and Drug Administration.
However, regardless of the safety cutoff, the study does show that a few products are delivering a concerningly high dose of heavy metals per serving.
How Consumer Reports did the study
The new study assessed 23 powder and ready-to-drink protein products from popular brands by sending three samples of each product to an independent commercial laboratory.
Consumer Reports considered anything over 0.5 micrograms per day from any single source to be above recommended maximum lead levels. That number comes from the California Office of Environmental Health Hazard Assessment, which established recommended maximum levels for a variety of substances that could cause cancer or fetal harm.
It is significantly more conservative than the safety standard for lead exposure used by the FDA for drugs and supplements. The discrepancy is driven by Consumer Reports’ aspirational goals of very low exposure versus the more realistic but actionable requirements from the FDA.
According to the FDA, the limit for the amount of lead that a person should consume from any single dietary supplement product is 5 micrograms per day. That number is 10 times higher than the Consumer Report limit.
The FDA has another standard for the total daily amount of lead a person can safely consume from food, drugs and supplements combined. This number, called the Interim Reference Level, or IRL, for lead is based on concentrations of lead in the blood that are associated with negative health effects in different populations.
For people who could become pregnant, that level is 8.8 micrograms per day, and for children it’s 2.2 micrograms per day. For everyone else, it’s 12.5 micrograms per day. Every food, drug and dietary supplement that contains lead contributes to the total daily exposure, which should be less than this amount.
What the report found
The nonprofit advocacy group found that 16 of the 23 products it tested exceeded 0.5 micrograms, the level of lead in a standard serving that the organization deems safe.
Four of the 23 products exceeded 2.2 micrograms, the FDA’s cutoff for the total daily amount of lead children should consume. Two products contained 72% and 88%, respectively, of the total daily amount of lead that the FDA deems safe for pregnant women.
In addition, Consumer Reports found that two of the 23 products delivered more than what it considers a safe amount of cadmium per serving, and one had more arsenic than was recommended.
The organization’s safety cutoff for cadmium is 4.1 micrograms per day, and for arsenic it is 7 micrograms per day. These numbers align fairly closely with the FDA’s recommended exposure limit for cadmium and arsenic from a single product. For cadmium, the FDA’s limit is set at 5 micrograms per day for a given dietary supplement product and 15 micrograms per day for arsenic.
The study found that the source of protein was key: Plant-derived protein products had nine times the lead found in dairy proteins like whey, and twice as much as beef-based protein.
Where are these heavy metals coming from?
Lead and other heavy metals are present in high amounts in volcanic rock, which comes from molten rock called magma beneath the Earth’s surface. When volcanic rock is eroded, the heavy metals contaminate the local soil and water supply. What’s more, some crop plants are especially efficient at extracting heavy metals from the soil and placing them in the parts of the plants that consumers ingest.
Fossil fuels, which come from deep within the Earth, also billow heavy metals into the air when they are burned. These substances then settle out into the soil and water. Finally, some fertilizers, herbicides and pesticides also contain heavy metals that can further contaminate soil and local water.
High levels of heavy metals have been found in plant-based protein powder, spices like cinnamon, dark chocolate, root vegetables like carrots and sweet potatoes, rice, legumes such as pea pods and many herbal supplements.
Should consumers be concerned? And what can they do?
Occasionally exceeding the daily recommended heavy metal doses is unlikely to result in serious health issues.
Repeated, heavy exposure to heavy metals can cause harm, however. When they accumulate in the blood, these substances can delay or impair mental functioning, damage nerves, soften bones and raise blood pressure – which in turn increases the risk of strokes and heart attacks. Heavy metals can also increase the risk of developing cancer.
It’s important to note that all the products Consumer Reports flagged have lead levels significantly lower than the maximum daily exposure levels established by the FDA.
Consumers can limit exposure by choosing dairy- or animal-based sources of protein products, since they generally seemed to have less heavy metal contamination than plant-based ones. However, some plant-based protein products in the study did not have high levels of heavy metals. Heavy metal levels vary widely in the environment, so the results from the Consumer Reports study show a snapshot in time. They might not be consistently accurate across batches if, for example, a manufacturer changes the source of its raw ingredients.
For protein products that do show an especially high heavy metal content, using them more sporadically, rather than daily, can reduce exposure. Studies suggest that organic plant-based products generally yield less heavy metal content than traditionally farmed ones.
Finally, the Consumer Reports study measured heavy metals in a single serving of protein products, so it’s helpful to understand what constitutes a serving for specific products and to avoid sharply increasing daily consumption.
Overall, the wide variation in lead levels across different protein powders and ready-made protein products highlights the need for manufacturers to tighten product testing and good manufacturing practices.

How to Practice Thoughtful Grief Etiquette Online
Grief experts advise caution in sharing condolences and loss-related information on social media, emphasizing the importance of prioritizing the grieving family’s needs. Thoughtful posting practices include waiting for family approval, reaching out privately first, and avoiding speculation about the cause of death. Compassionate communication is essential in these sensitive situations.
(Feature Impact) News of a death can spread online in seconds – often before families have notified close family members privately. That’s why grief experts urge people to rethink how they share condolences, tributes and loss-related information on social media, particularly during the winter months when grief can feel especially isolating.
“Grief etiquette is about putting the needs of the grieving family first, not our urge to say something publicly,” said Dr. Camelia L. Clarke, National Funeral Directors Association (NFDA) spokesperson, funeral director and grief educator with nearly 30 years of experience. “Just because information can be shared instantly doesn’t mean it should be.”
Social media has become a common place for sharing condolences, tributes and memories. However, grief experts caution that, without thoughtful consideration, online posts can unintentionally cause harm. Knowing when to post, what to say and when to remain silent can make a meaningful difference for families experiencing loss.
Consider this advice from the experts at the NFDA.
Grief Etiquette in the Digital Age
Grief etiquette refers to the unspoken guidelines for how individuals acknowledge death, loss and mourning, particularly online.
According to Clarke, one of the most important principles is restraint.
“When a death is shared online too quickly, families can feel exposed and overwhelmed at a moment when they’re still processing the loss themselves,” she said. “Waiting is an act of compassion.”
Best Practices for Posting About Loss Online
As social media continues to play a role in modern mourning, grief professionals encourage users to pause before posting and consider a few key guidelines:
- Let the family lead. Don’t post about a death until the immediate family has made it public.
- Ask permission. Obtain consent before sharing photos, stories or tributes.
- Reach out privately first. A direct message, call or handwritten note can be more meaningful than a public comment.
- Avoid speculation. Don’t ask about or share details regarding the cause of death.
- Offer ongoing support. Grief extends far beyond the first days or weeks after a loss.
What to Say (and Avoid)
When expressing condolences online, experts recommend simplicity, sincerity and sensitivity. Messages that acknowledge loss without attempting to explain or minimize it are often the most supportive.
Helpful phrases include:
- “I’m sorry for your loss.”
- “Thinking of you and your family.”
- “I’m here if you want to talk or need anything.”
By contrast, well-meaning cliches can unintentionally cause harm. Phrases such as “They’re in a better place” or “Everything happens for a reason” may reflect the speaker’s beliefs, but they can feel dismissive to someone grieving.
“Grieving people don’t need answers – they need presence,” Clarke said. “Listening matters more than saying the perfect thing.”
Resources for Families and Friends
As digital spaces continue to shape how people communicate during life’s most difficult moments, experts agree empathy, patience and respect remain timeless.
“Grief is deeply personal,” Clarke said. “When we slow down and lead with compassion, we honor both the person who has died and those who are left to grieve.”

Fresh Thinking About Frozen: Bring Quality Meals to the Table While Cutting Food Waste and Stretching Your Budget
For many families, the freezer is for last-minute meal options. However, new federal nutrition guidance and growing scientific consensus reveal a different reality: frozen foods can be the starting point for healthy eating, not a backup plan.
Last Updated on February 21, 2026 by Daily News Staff
(Feature Impact) The key to easy preparation of high-quality meals, wasting less food and saving money may already be sitting in your kitchen.
For many families, the freezer is for last-minute meal options. However, new federal nutrition guidance and growing scientific consensus reveal a different reality: frozen foods can be the starting point for healthy eating, not a backup plan. That’s why the American Frozen Food Institute (AFFI) is launching “Fresh Thinking About Frozen,” a campaign to help families discover these benefits of frozen foods.
Making Nutrition Achievable
The recently released 2025-2030 Dietary Guidelines for Americans, the nation’s top nutrition advice, emphasizes portion control and nutrient-dense foods. Frozen options deliver on both counts.
Families who keep frozen produce on hand tend to eat more fruits and vegetables overall. Pre-portioned frozen meals also help people eat what they need without overdoing it. Plus, the convenience factor matters: frozen berries are ready for a morning smoothie, pre-cut frozen vegetables can be added to tonight’s stir-fry and a balanced frozen meal can be quickly paired with a salad.
That isn’t cutting corners. It’s being smart on how best to feed a family well.
Freezing Hits the Pause Button on Fresh Foods
Freezing food only changes a food’s temperature, not its nutrition. Freezing keeps food close to its original state without requiring additives.
Produce begins to lose nutritional value right after it’s harvested. Freezing fruits and vegetables hours after harvest pauses nutrient degradation and locks in the vitamins and minerals, so the food remains farm fresh even as it travels across the country to your grocery store. Frozen meals are similarly made with real ingredients and turned into just-cooked recipes then frozen for families to eat when they’re ready.
The nutrition community understands this. A recent survey conducted by AFFI found 94% of registered dietitians agree frozen fruits and vegetables are just as nutritious as their fresh counterparts. Another 92% said frozen foods offer a variety of nutritious meal offerings. These findings are central to the “Fresh Thinking About Frozen” message: Frozen is not second-best. It’s simply smart.
Solving the Food Waste Problem
Nearly 40% of food in the United States gets thrown away, according to the nonprofit ReFED. That translates to roughly $1,500 per year per household, straight into the trash along with unused produce and forgotten leftovers.
Frozen helps fix that problem. Eight in 10 consumers agree buying frozen helps reduce food waste at home, AFFI research finds. The reason is simple: You use what you need, when you need it and the rest stays perfectly preserved. No more dreading the refrigerator cleanouts and feeling guilty over the uneaten food going into the trashcan.
Time for Fresh Thinking
Families already making this shift aren’t settling for less. They’re strategic about nutrition, budget and time. They integrate the freezer into regular meal planning. They feel confident about providing quality foods that are simply frozen.
The freezer isn’t a place of last resort. It’s a tool for eating well in real life. Visit frozenadvantage.org/FTAF for tips, recipes and resources to make the most of your freezer.

Stacking Healthy Habits for Progress, Not Perfection
Healthy Habits: Many struggle with building healthier habits due to unrealistic expectations rather than lack of motivation. The American Heart Association’s My Life Check tool offers personalized heart health insights, helping to set attainable goals. Simple lifestyle changes—focused on nutrition, movement, sleep, and stress management—can gradually lead to significant health improvements.
(Feature Impact) Despite the best of intentions, it’s common for plans to build healthier habits to fall flat. Often, the culprit isn’t a lack of motivation or discipline; rather, it’s unrealistic expectations.
Overhauling your lifestyle requires a level of commitment that isn’t always practical. Understanding your personal health needs and the challenges you need to overcome can help give you a more realistic roadmap toward better health.
Tools to Guide You
Every plan needs a starting point and there are many reputable sources that can help guide you toward a plan that addresses your personal health needs.
For example, the American Heart Association introduced My Life Check, a simple, free tool to help individuals understand their heart health and what’s driving it. Users answer simple questions about their daily habits and health factors to get a personalized Heart Health Score in minutes.
The results are private and downloadable, giving you full control of your information. The tool turns big goals into small, specific actions you can start right away. Knowing your numbers relative to your heart health (and where you are in comparison to target ranges for optimal health) can help you decide how to build a better map to get you where you want to be.
While the report is customized to each individual, no personal data is stored and answers are only used to calculate health scores and provide personalized recommendations and practical steps to improve your health, so you can use your results to focus on what matters most to you. Every small step you take, such as moving more, eating smarter, sleeping better or managing stress, can add up over time.
Finding Your Path
Once you’re armed with data and know where you stand on your heart health numbers, small steps become clearer and more manageable. That knowledge makes it easier to choose one area to focus on, such as getting more sleep, taking daily walks or adding more color to your meals.
Healthy changes don’t need to be expensive or complicated. The best habits are ones that fit real life when every action you take moves you closer to your goals.
Eat Smart
Choose foods that help you feel your best, one meal at a time. Add more color to your plate and focus on balance, not restriction. Simple, affordable swaps can make a real difference.
Move More
Find movement that fits your life, such as a walk, a stretch or dancing while you cook. Every bit of activity counts and it all supports your heart and mind. Move for joy, not just for results.
Sleep Well
Rest is a foundation of good health, not a reward. Protect your bedtime routine and give your body the recovery it deserves. Notice how good sleep makes everything else easier.
Manage Stress
Check in with yourself regularly, both mentally and emotionally. Create simple moments to pause, breathe, laugh or step outside. Connection, kindness and calm all support a healthy heart.
Staying motivated and on track is also easier when you can check back in, see your progress and realize the steps you’re taking are making an impact. Checking in every few months to see how you can grow gives you the chance to celebrate your progress, learn from challenges and keep building lasting habits that feel good.
