Tag: Supplement contamination

According to a study published in The New England Journal of Medicine, adverse effects from dietary supplements are responsible for an estimated 23,000 emergency department visits each year. This highlights the critical importance of understanding what supplements are not safe to take and why, to protect your health and avoid serious harm.

According to a 2015 study from Columbia University, over half (55%) of popular probiotic supplements tested contained detectable traces of gluten, including some labeled 'gluten-free'. While probiotics themselves are naturally free of gluten, manufacturing practices and certain ingredients can introduce this protein into the final product, posing a significant risk for those with celiac disease or gluten sensitivity.

According to a 2015 Harvard study, some supplements are linked to numerous emergency room visits annually. Supplements carry potential risks, including drug interactions, manufacturing issues, and dangerous side effects.

According to a recent study, researchers analyzing 26 prenatal vitamins found that all samples contained some level of toxic elements, such as lead and cadmium. This alarming data directly addresses the question: do all prenatal vitamins contain heavy metals? The answer is more complex than a simple yes or no, but confirms that contamination is a widespread problem.

According to a 2025 report from the Clean Label Project, nearly half of the protein powders tested contained detectable levels of heavy metals. Finding a pure protein that has no heavy metals requires careful consideration of the source, processing, and a manufacturer's commitment to third-party testing and transparency.

Exposure to lead was attributed to more than 1.5 million deaths globally in 2021, primarily due to cardiovascular effects. Given that some reports have found detectable levels of lead in popular protein powders, it is crucial for consumers to understand the potential health risks.

According to reports from nonprofit organizations like the Clean Label Project, many protein powders, particularly plant-based options, contain detectable levels of heavy metals such as lead and cadmium. However, when evaluating the specific question, 'Are there heavy metals in Optimum Nutrition?', it is necessary to look at independent testing and the company's manufacturing practices.

Independent laboratory tests from the consumer advocacy group Lead Safe Mama have on occasion detected trace amounts of lead in specific batches of Mary Ruth Organics products. These findings have prompted consumer questions about product safety, requiring a deeper investigation into whether Mary Ruth vitamins have lead.

According to a 2020 study by the Clean Label Project, a significant percentage of best-selling collagen supplements were found to contain detectable levels of heavy metals such as lead, arsenic, and cadmium. This raises a critical question for consumers: does bovine collagen contain heavy metals?

According to a 2020 Clean Label Project study, 64% of tested collagen products had measurable levels of arsenic, raising concerns about supplement safety. So, does bovine collagen have heavy metals, and if so, how can consumers ensure their safety?
