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 avoid seeing disturbing video on social media and protect your peace of mind
How to avoid seeing disturbing video on social media and protect your peace of mind

How to avoid seeing disturbing video on social media and protect your peace of mind
When graphic videos like those of the recent shooting of a protester by federal agents in Minneapolis go viral, it can feel impossible to protect yourself from seeing things you did not consent to see. But there are steps you can take.
Social media platforms are designed to maximize engagement, not protect your peace of mind. The major platforms have also reduced their content moderation efforts over the past year or so. That means upsetting content can reach you even when you never chose to watch it.
You do not have to watch every piece of content that crosses your screen, however. Protecting your own mental state is not avoidance or denial. As a researcher who studies ways to counteract the negative effects of social media on mental health and well-being, I believe it’s a way of safeguarding the bandwidth you need to stay engaged, compassionate and effective.
Why this matters
Research shows that repeated exposure to violent or disturbing media can increase stress, heighten anxiety and contribute to feelings of helplessness. These effects are not just short-term. Over time, they erode the emotional resources you rely on to care for yourself and others.
Protecting your attention is a form of care. Liberating your attention from harmful content is not withdrawal. It is reclaiming your most powerful creative force: your consciousness.
Just as with food, not everything on the table is meant to be eaten. You wouldn’t eat something spoiled or toxic simply because it was served to you. In the same way, not every piece of media laid out in your feed deserves your attention. Choosing what to consume is a matter of health.
And while you can choose what you keep in your own kitchen cabinets, you often have less control over what shows up in your feeds. That is why it helps to take intentional steps to filter, block and set boundaries.
Practical steps you can take
Fortunately, there are straightforward ways to reduce your chances of being confronted with violent or disturbing videos. Here are four that I recommend:
- Turn off autoplay or limit sensitive content. Note that these settings can vary depending on device, operating system and app version, and can change.
https://datawrapper.dwcdn.net/d1deR/2
- Use keyword filters. Most platforms allow you to mute or block specific words, phrases or hashtags. This reduces the chance that graphic or violent content slips into your feed.
- Curate your feed. Unfollow accounts that regularly share disturbing images. Follow accounts that bring you knowledge, connection or joy instead.
- Set boundaries. Reserve phone-free time during meals or before bed. Research shows that intentional breaks reduce stress and improve well-being.
Reclaim your agency
Social media is not neutral. Its algorithms are engineered to hold your attention, even when that means amplifying harmful or sensational material. Watching passively only serves the interests of the social media companies. Choosing to protect your attention is a way to reclaim your agency.
The urge to follow along in real time can be strong, especially during crises. But choosing not to watch every disturbing image is not neglect; it is self-preservation. Looking away protects your ability to act with purpose. When your attention is hijacked, your energy goes into shock and outrage. When your attention is steady, you can choose where to invest it.
You are not powerless. Every boundary you set – whether it is turning off autoplay, filtering content or curating your feed – is a way of taking control over what enters your mind. These actions are the foundation for being able to connect with others, help people and work for meaningful change.

I’m the executive director of the Post-Internet Project, a nonprofit dedicated to helping people navigate the psychological and social challenges of life online. With my team, I designed the evidence-backed PRISM intervention to help people manage their social media use.
Our research-based program emphasizes agency, intention and values alignment as the keys to developing healthier patterns of media consumption. You can try the PRISM process for yourself with an online class I launched through Coursera in October 2025. You can find the course, Values Aligned Media Consumption, on Coursera. The course is aimed at anyone 18 and over, and the videos are free to watch.

Understanding Cardiovascular Disease Risk Factors: Numbers to Know in 2026
The American Heart Association’s 2026 update reveals a decrease in deaths from heart disease and stroke, despite rising rates of high blood pressure, diabetes, and obesity. Following their Life’s Essential 8 guidelines can prevent 40% of cardiovascular deaths, emphasizing the importance of healthier lifestyles for improved heart health.
Understanding Cardiovascular Disease Risk Factors: Numbers to Know in 2026
(Family Features) Taking care of your heart with healthy behaviors may be at the top of your wellness priority list already, and there may be good news about the effects of adhering to expert recommendations.
New information from the American Heart Association’s 2026 Heart Disease & Stroke Statistics Update shows deaths from heart disease and stroke are on the decline. However, rates continue to climb for high blood pressure, diabetes and obesity – all of which are health risk factors that contribute to cardiovascular disease.
Following expert guidance can be your prescription for better health as 80% of heart disease and stroke is preventable.
To help maintain and improve your cardiovascular health, consider following the American Heart Association’s Life’s Essential 8, which is a set of four health behaviors (eat better, be more active, quit tobacco and get healthy sleep) and four health factors (manage weight, control cholesterol, manage blood sugar and manage blood pressure).
In the United States, optimal Life’s Essential 8 scores could prevent up to 40% of annual all-cause and cardiovascular disease deaths among adults.
Consider these highlights from the statistics update:
- Heart disease remains the leading cause of death in the U.S. and stroke is the No. 4 leading cause of death.
- Together, heart disease and stroke accounted for more than a quarter of all deaths in the U.S. in 2023.
- Cardiovascular diseases, including all types of heart disease and stroke, claim more lives in the U.S. each year than all forms of cancer and accidental deaths — the Nos. 2 and 3 causes of death – combined.
- On average, every 34 seconds, someone died of cardiovascular disease in 2023.
- On average, about two people died of heart disease every 3 minutes in the U.S. in 2023.
- On average in 2023, someone died of stroke every 3 minutes, 14 seconds in the U.S.
- Nearly half of U.S. adults now have high blood pressure.
- Nearly 29.5 million U.S. adults have diagnosed diabetes.
- About 50% of U.S. adults have obesity or severe obesity, and 28.1% of youth ages 2-19 have obesity.
- Only 1 in 4 U.S. adults meets national physical activity guidelines. Only 1 in 5 U.S. youths ages 6-17 are physically active for 60 minutes or more every day of the week.

Get Smart About Your Heart: 4 tips to improve heart health
Heart health is essential for overall well-being, particularly as heart disease is a leading cause of death in the U.S. Key strategies include regular checkups, healthy eating—especially fruits like grapes—consistent exercise, and stress management to minimize risks.
(Family Features) A crucial component of overall well-being, heart health can be a barometer for living a long, healthy and happy life. Because heart disease is the leading cause of death in the United States, according to the Centers for Disease Control and Prevention, taking steps to reduce your controllable risk factors – including poor diet, stress and inactivity – can set you on the right path.
From regular checkups and reducing stress to eating well – including heart-healthy snacks like grapes – and exercising regularly, these simple steps can help boost your heart health.
Know Your Numbers
Knowing key health metrics such as blood pressure, cholesterol levels, blood sugar levels and body mass index can help you and your health care provider identify potential risks early. Schedule annual checkups and discuss any concerns you may have about your heart health. Early detection and risk factor management can reduce the likelihood of developing heart disease.
Eat More Fruits and Vegetables
Incorporating a variety of colorful fruits and vegetables into your diet can ensure you get a broad range of vitamins, minerals, fiber and antioxidants, all of which contribute to a healthy cardiovascular system. For example, leafy greens like spinach and kale are high in potassium, which helps manage blood pressure. Fresh grapes contain 7% of the daily recommended intake of potassium, are a good source of vitamin K and are also a natural source of beneficial antioxidants and other polyphenols, including flavonoids, that can help relax blood vessels and promote healthy circulation. Some studies also suggest grapes have a beneficial impact on blood lipids and more.
In fact, one study found women who consumed 1 1/4 cups of grapes every day benefited from reduced blood triglyceride levels, LDL cholesterol levels, inflammatory proteins and other markers of heart disease.
Bright, juicy and bursting with flavor, Grapes from California can be enjoyed by the handful or blended with rich bananas, tangy Greek yogurt and a hint of almond in The Great Grape-Acai Smoothie Bowl for a delicious blend of fruity flavors at breakfast, lunch or snack time – it not only tastes great, but supports a healthy heart.
Get Moving
Regular physical activity is one of the most effective ways to improve heart health. Exercise strengthens the heart muscle, improves blood circulation and helps maintain a healthy weight. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, as recommended by the American Heart Association, such as walking, jogging or swimming with strength training exercises like lifting weights or using resistance bands mixed in to help reduce the risk of heart disease and improve overall cardiovascular health.
Manage Stress
Consider your stress level: chronic stress can negatively impact heart health, increasing blood pressure and other risk factors for heart disease. Techniques such as deep breathing, meditation, yoga and regular physical activity can help manage stress levels and maintain a healthy heart. Additionally, taking time to engage in hobbies, spending time with loved ones and ensuring adequate sleep are stress-reducing activities that improve overall well-being and heart health.
