Yes, Boost Plus is officially labeled and confirmed as gluten-free by its manufacturer, Nestlé Health Science. For those with celiac disease or non-celiac gluten sensitivity, this is a crucial piece of information that makes the product a safe option for nutritional supplementation. The product’s labeling adheres to the strict regulations set forth by the Food and Drug Administration (FDA) regarding gluten-free claims. These regulations stipulate that a product must contain less than 20 parts per million (ppm) of gluten to be legally marketed as gluten-free.

Deciphering the Gluten-Free Label

The presence of the term “gluten-free” on a product like Boost Plus is a reliable indicator that it does not contain wheat, rye, barley, or their crossbred hybrids. For individuals with celiac disease, even small amounts of gluten can trigger a harmful immune response, so adhering to products that meet the <20 ppm standard is essential.

Avoiding Cross-Contamination and Reading Labels

While Boost Plus is formulated to be gluten-free, it's wise for individuals with celiac disease to remain vigilant about cross-contamination in their overall diet. For example, ensure any utensils or glasses used for the drink are clean and not exposed to gluten-containing items. The “gluten-free” label on the package signifies the manufacturer has taken steps to ensure the finished product meets the necessary safety threshold. It is important to remember that “wheat-free” does not automatically mean a product is gluten-free, as it could still contain barley or rye. For maximum peace of mind, some individuals with severe sensitivity prefer products with third-party certification logos, though Boost's manufacturer claim is a strong assurance.
