Protein powders and ready-to-drink shakes have become part of everyday life for millions of people. They’re in gym bags, office drawers, kitchen cabinets, and even school backpacks. Many people use them to build muscle, lose weight, recover from workouts, or simply get more protein without cooking. But a major new investigation by Consumer Reports has uncovered something most people never expect to find in their daily shake: high levels of lead.

Consumer Reports tested 23 popular protein powders and shakes and found that more than two-thirds contained more lead in a single serving than their food safety experts consider safe to consume in an entire day.  This finding has sparked widespread concern, especially among people who rely on these products every day.

This article breaks down what Consumer Reports found, why lead shows up in protein powders, which types of products were most contaminated, and what you can do to protect yourself.

Why Lead in Protein Powder Is a Big Deal

Lead is a toxic heavy metal that can harm nearly every organ system in the body. Public health authorities, including the FDA and the World Health Organization, repeatedly state that there is no known safe level of lead exposure.  Even small amounts can accumulate over time, especially in children, pregnant people, and adults who consume contaminated products daily.

Consumer Reports uses a benchmark based on California’s Prop 65 maximum allowable dose level of 0.5 micrograms per day for lead. Their experts consider this one of the most protective standards available.  When a single scoop of protein powder exceeds that threshold, it means you may be getting more lead than recommended before you’ve even eaten breakfast.

What Consumer Reports Tested

The investigation included 23 protein powders and ready-to-drink shakes from well-known brands. The products covered a wide range of protein sources:

• Plant-based powders
• Whey and other dairy-based powders
• Beef-based protein powders
• Ready-to-drink shakes

The results were troubling. More than two-thirds of the tested products contained more lead in one serving than Consumer Reports experts say is safe for an entire day. Some products contained more than 10 times that amount.

Plant-Based Powders Had the Highest Lead Levels

One of the most striking findings was that plant-based protein powders had significantly higher lead levels than dairy-based or beef-based powders. On average, plant-based products contained nine times more lead than dairy-based proteins and twice as much as beef-based ones.

This doesn’t mean all plant-based powders are unsafe, but it does mean contamination is more common in this category. Heavy metals can enter plant-based products through soil, water, and processing methods. Plants naturally absorb minerals from the ground, and if the soil contains heavy metals, those metals can end up in the final product.

The Most Concerning Products

Two plant-based powders stood out as having extremely high levels of lead:

• Naked Nutrition Vegan Mass Gainer
• Huel Black Edition

Consumer Reports found that Naked Nutrition’s Vegan Mass Gainer contained 1,572 percent more lead than the recommended level, while Huel Black Edition contained 1,288 percent more.  Consumer Reports experts advise avoiding these products entirely.

On the other end of the spectrum, Muscle Tech Mass Gainer showed no detectable lead, meaning no limit was placed on its use.

Why Lead Shows Up in Protein Powders

Lead contamination can happen at several points:

• Soil contamination affecting plant-based ingredients
• Water used during processing
• Manufacturing equipment
• Packaging materials
• Supply chain inconsistencies

Consumer Reports notes that heavy metal contamination in protein powders has become even more common compared to their testing 15 years ago. Average lead levels were higher this time, and fewer products had undetectable amounts.

Should You Be Worried If You’ve Been Drinking These Products?

Many people have consumed protein powders daily for years. Consumer Reports addressed this concern directly: if you’ve been using a product with elevated lead levels, it may be worth talking to your doctor about whether a blood lead test is appropriate.

However, the bigger takeaway is that lead exposure adds up over time. Even small daily amounts can accumulate, especially if you’re using multiple servings per day.

What You Can Do Right Now

Here are practical steps to reduce your risk:

1. Check Whether Your Protein Powder Was Tested

Consumer Reports published detailed results for all 23 products. If your brand was included, review the findings to see where it falls.

2. Consider Reducing Daily Use

Consumer Reports advises against daily use of most protein powders because many contain high levels of heavy metals and none are necessary to meet your protein goals.

3. Choose Products With Lower Lead Levels

Dairy-based powders generally had lower contamination than plant-based ones. If you tolerate dairy, whey protein may be a safer option.

4. Rotate Protein Sources

Instead of relying solely on powders, consider whole-food protein sources like eggs, chicken, beans, lentils, yogurt, and tofu.

5. Look for Brands That Publish Third-Party Testing

Some companies voluntarily share heavy metal testing results. While not perfect, transparency is better than silence.

6. Avoid Products Consumer Reports Says Not to Use

Naked Nutrition Vegan Mass Gainer and Huel Black Edition were flagged as products to avoid entirely.

How Consumer Reports Conducted the Testing

Consumer Reports used accredited laboratories to measure heavy metal levels in each product. They analyzed serving sizes, protein types, and contamination patterns. Their methodology also accounted for differences in serving sizes and flavors.

This investigation is part of a broader effort to highlight hidden risks in everyday food and supplement products. Consumer Reports has tested protein powders before, but this round showed higher average lead levels and more widespread contamination.

The Bigger Picture: Why This Matters

Protein powders are marketed as clean, healthy, and essential for fitness. But the reality is more complicated. Supplements are not regulated the same way as medications, and contamination can slip through the cracks.

The booming wellness industry has created a huge demand for protein products, but safety standards have not kept pace. As Consumer Reports points out, the risks are growing right alongside the industry.

Lead exposure is not something to take lightly. Even if you feel fine, long-term exposure can affect your nervous system, kidneys, cardiovascular system, and cognitive function.

A Simple Way to Think About It

If you wouldn’t drink water with elevated lead levels every day, you shouldn’t drink a protein shake with elevated lead levels every day either.

Protein powders can be helpful, but they should be used thoughtfully, not automatically.

Protein powders and shakes are convenient, popular, and often marketed as part of a healthy lifestyle. But the Consumer Reports investigation shows that many of these products contain more lead in a single serving than experts consider safe for an entire day. Plant-based powders were the most contaminated, and a few products had extremely high levels.

You don’t need to panic, but you should stay informed. Check your brand, consider reducing daily use, and choose products with lower contamination. Whole foods remain the safest and most reliable way to get protein without unwanted heavy metals.
