Your Favorite Stanley Cup Has Lead In It

Is Your Favorite Mug Safe?

The Stanley Cup, more specifically the 40-ounce Stanley Adventure Quencher Travel Tumbler, has significantly risen in popularity due to Americans' obsession with staying hydrated. Not only do we aspire to consume the highest quality water, but we also uphold our reusable bottle to that same principle as a tool to help us reach our goals. Nowhere is this more evident than in the 55 million views that #emotionalsupportwaterbottle has received on TikTok or the waitlist to purchase this in-demand tumbler that once topped out in 150,000 eager buyers.

But recent news about lead being used in the manufacturing process of this internet favorite has many people wondering: are they still safe to use? Let's unpack the facts and what it means for your health.

The Lead Lowdown

According to the company’s website, its “vacuum insulation technology” maintains the cup’s contents at an ideal temperature using “an industry standard pellet to seal the vacuum insulation at the base of our products.” The sealing material “includes some lead” but the area is covered with a layer of stainless steel, which the company says makes the lead inaccessible under normal use. 

Potential Risks

While users are in direct contact with the lead, if the stainless steel barrier is compromised (e.g., through damage), that’s when a user should be concerned. Lead exposure, especially for young children, can have serious health consequences. Here's a deeper look:

  1. Irritability, fatigue, headaches, and learning difficulties in children.
  2. Abdominal pain, muscle aches, and high blood pressure in adults.
  3. Severe cases can lead to seizures, coma, and even death.
  • Specific Health Risks for Different Age Groups
  1. Pregnant women and fetuses: Lead exposure can damage the developing brain, leading to lower IQ, behavioral problems, and even hearing loss in children.
  2. Infants and young children: Their developing bodies absorb lead more readily, putting them at higher risk of neurological and cognitive issues.
  3. Adults: While less susceptible than children, chronic lead exposure can still increase blood pressure, damage the kidneys and nervous system, and contribute to heart disease.

Taking Charge of Your Health

Be sure to inspect your Stanley Cup for any damage, especially near the base. If concerned, avoid using a damaged cup and contact Stanley for a replacement. You can also consider alternative brands that don't use lead in their manufacturing process. While Stanley maintains their cups are safe under normal use, here are some lead-free and eco-friendly alternatives:

  • S'well Bottles: S’well bottles are made of food-grade stainless steel, and are BPA-free. They are known for their sleek design and temperature retention, as well as boast various certifications for safety and sustainability.
  • Klean Kanteen: Committed to using non-toxic materials, Klean Kanteen offers a wide range of insulated bottles and mugs made from food-grade stainless steel and bamboo. Plus, it keeps drinks cold for up to 75 hours!
  • Hydro Flask All Around Tumbler: Another popular choice, Hydro Flask uses BPA-free and lead-free materials in their insulated bottles and containers. They also offer various size and lid options to fit your needs.

Remember, you have the power to make informed decisions about the products you use and the impact they have on your health. By staying informed and taking action, you can empower yourself to live a healthier, more mindful life. At the end of the day, while this isn’t a call to toss your Stanley Cup, it is a good reminder to be mindful of potential toxins in everyday products.
