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.

Join the Fight Against ALS: Register and Make a Difference
(Feature Impact) Every year, doctors tell more than 5,000 Americans they have amyotrophic lateral sclerosis, better known as ALS. It is a life-changing diagnosis.
Still, it’s hard to estimate the total number of ALS cases in the United States. No one knows what causes most cases of ALS, something the U.S. National ALS Registry is working to change.
In honor of ALS Awareness Month, learn more about the registry, how the information is used and how to enroll if you have ALS.
What is ALS?
ALS is a disease that affects the nerve cells that make muscles work in the body. This disease makes the nerve cells stop working and die. The nerves lose the ability to trigger specific muscles, which causes the muscles to become weak and leads to paralysis.
What is the registry?
“The National ALS Registry is a program of, by and for those living with ALS,” said Dr. Paul Mehta, principal investigator of the Registry. “The program collects, manages and analyzes data about people with ALS in the United States. It includes data and information provided by individuals who choose to register and complete the risk factor surveys.”
What is its purpose?
The main purpose is to gather information that can be used in the fight against ALS. The information is used to:
- Estimate the number of new cases of ALS diagnosed each year
- Estimate the number of people who have ALS at any given point in time
- Better understand who gets ALS and what factors affect the disease
- Enhance research that could improve care for people with ALS
How do researchers use the data?
Researchers can use the data to look for disease pattern changes over time and try to identify whether there are common risk factors among people with ALS. Since 2010, the registry has funded more than a dozen studies exploring potential ALS risk factors.
What does participation look like?
Individuals with ALS are encouraged to share their stories, enhancing ALS data and supporting research efforts. People living with ALS can help the National ALS Registry by completing up to 18 risk factor surveys, covering topics such as occupational history and environmental exposures, which help create a more complete picture of their ALS story.
How can someone join?
Anyone living with ALS can enroll. By joining and taking the risk factor surveys, individuals living with ALS can help future generations.

Last Updated on June 29, 2026 by Daily News Staff
(Family Features) Shaping the future of public health into an equitable one means ensuring all people and communities have access to the health care and resources they need to live well. The nation requires a strong, diverse public health workforce to accomplish that goal.
That’s why AmeriCorps and the Centers for Disease Control and Prevention launched Public Health AmeriCorps – to support the recruitment, training and development of early career public health workers who can serve their local communities.
Bridging national service and public health, the initiative supports a diverse group of early career professionals working to address today’s public health challenges in a range of roles, including:
- Health education and training
- Community outreach and engagement
- System navigation, referrals and linkage to care
- Research, data collection, analysis and assessment
What Members are Saying
Everyone was impacted by the COVID-19 pandemic – including Dionne Johnson, who lost a loved one to the virus.
“I had a family member die from COVID-19, and it really touched me,” Johnson said. “That gave me the passion and lit the fire under me to actually pursue a career in public health.”
Now, Johnson is realizing her dreams of transforming public health in her community. In her work, she wants to teach people in Black and brown communities how they can learn to be healthy and advocate for themselves.
Another member, Jaiden Singh, is the son of immigrants. Singh launched a promising career in public health so he can give back to the community where he grew up.
“Being a part of the organization not only has really supplemented my education that I’m working toward in public health and policy, it has also given me the opportunity to do work that I am really passionate about in a community that I have known all my life and really do love,” Singh said. “I would highly recommend being a part of this really valuable and inspiring community.”
Action That Creates Impact
The diverse work of Public Health AmeriCorps benefits not only program members but also the communities they serve. As examples of the program at work, members have:
- Provided overdose rescue education, raised awareness about opioid use disorder and harm reduction strategies and distributed overdose rescue kits containing naloxone (an overdose-reversing nasal spray).
- Held back-to-school COVID-19 testing events, distributed early childhood health education and built community gardens in underserved communities.
- Participated in a community mental health crisis intervention system to assess, stabilize and link people in crisis to follow-up care and services.
- Supported elementary schools as part of a dental hygiene program that sends out staff and volunteers to provide free teeth cleanings to students.

Balance Your Plate with Produce, Protein and Whole Grains

(Feature Impact) Making health-conscious decisions with your at-home menu doesn’t have to be complicated, but it does require commitment and a little more foresight at the grocery store. Simple adjustments to overall eating patterns, like building your plate around produce, powerful proteins and whole grains, can encourage better health.
Nutritious meal-planning can be easy, affordable and delicious – and it all starts with a little balance. Consider this advice from the American Heart Association’s Healthy for Good initiative, nationally sponsored by the Egg Nutrition Center, to adequately round out a healthy plate.
Fill Half Your Plate with Fruits and Veggies
Loaded with nutrients, fresh produce is a perfect place to start each plate. Fill about half your plate with combinations of bananas, strawberries, blueberries, sweet potatoes, peas, carrots and more of your favorites. To boost variety with each meal, look for fruit and veggie blends or step out of your usual routine and try something new.
Grocery tip: Frozen fruits and veggies are often cheaper and just as delicious as their fresh counterparts. It’s frozen right after it’s picked, locking in freshness for a longer shelf life. Just be sure to avoid products with added salt or sugar.
Carve Out a Quarter of the Plate for Powerful Proteins
Healthy food isn’t just fuel. It should be easy and nourish you, too. Look for versatile solutions that provide a protein power-up like skinless chicken breast, no-salt-added beans, low-sodium tuna, tofu or eggs.
High-quality protein from foods, along with a balanced diet and regular exercise, can help support the muscles in your body. Eggs are an example, along with lean animal protein and some plant-based proteins. According to the American Heart Association’s guidelines, healthy people can include up to one whole egg daily, and up to seven per week, as part of a heart-healthy diet. For older adults with normal cholesterol, two eggs per day is acceptable.
Eggs deliver both protein and choline, nutrients that help support growing brains and bodies, especially early in life. In fact, many Americans don’t get enough choline, a critical nutrient for supporting brain development, memory and mood.
Grocery tip: Stock up on proteins that offer both versatility and affordability, helping you cook multiple meals per week without putting a dent in your wallet. Eggs are a perfect example as they can be used at any meal, not just breakfast – try them in wraps or omelets in the morning, hard-boil them to go with a lunchtime salad or add to a frittata at dinner.
Save a Corner for Whole Grains
Finally, fill that last quarter of the plate with ready-to-go whole grains, many of which provide dietary fiber that can support a healthy heart and healthy digestion. Conversely, most refined grains contain little or no fiber.
Examples of whole grains include barley, brown rice, corn, oatmeal, rolled or steel-cut oats, popcorn, quinoa, sorghum and wild rice, along with products labeled “whole grain” or “whole wheat” like bread or pasta.
Grocery tip: Look for whole grains that can make mealtime a cinch. Corn tortillas, instant oats and even popcorn can help you create nutritious plates and better-for-you snacks with the snap of your fingers. Try keeping packets of pre-cooked brown rice on hand to bulk up favorite dishes or toss with leftovers to round out a healthy plate.

3 Tips to Complement a Healthy, Balanced Plate
Nutrition isn’t just about what’s on your plate – it’s also about what’s next to it and how much is on it. Pair a balanced meal with this advice to help take healthy eating to the next level.
Stay Hydrated
If it’s not already a habit, add a glass of water to each meal. Staying hydrated helps your heart pump blood throughout the body, get rid of waste and regulate body temperature. While water is the best source of hydration, water-rich foods like fruits and vegetables can also play a role.
Watch Portion Sizes
Pay attention to suggested servings from your favorite food groups. For example, one slice of whole-grain bread, 1/2 cup of cooked pasta and two ounces of cheese (about the size of a domino) are the suggested serving sizes for these popular foods.
You can serve and eat smaller portions by:
- When cooking at home, offer the proper serving size to each family member then put extra food away for leftovers.
- When dining out, skip appetizers and split your meal with a friend or partner.
- Avoid eating while watching TV or at your computer. It may be harder to control how much you’re eating if you’re not paying full attention.
- Mindfully measure out your snacks – even fruits and veggies – into appropriate portions before serving instead of helping yourself directly from the bag or box.
Limit Salt
While sodium supports vital functions like controlling your body’s fluid balance, excess sodium in your bloodstream pulls water into the blood vessels, increasing the amount of blood inside them and thus increasing blood pressure. More than 70% of the sodium people eat comes from packaged, prepared and restaurant foods due to salt added for flavoring, stabilizing, preserving and reducing bacterial risk, according to the American Heart Association.
Cutting back on sodium can help reduce the rise in blood pressure that occurs as you age, even if you don’t have high blood pressure now. It may also help reduce the risk of heart attack, heart failure, kidney disease and more.
Try cooking more meals at home where you can control sodium intake, flavoring foods with herbs and spices instead of table salt and rinsing canned beans and vegetables to wash away excess sodium.
