Does Woodstock Vitamins test its products for quality?

Yes. All of our products are third-party tested for heavy metals like lead, cadmium, and mercury, as well as contaminants like E. coli, Salmonella, yeast, and mold. Every product we recommend must meet the Supplement Quality Standard — our internal benchmark for quality, manufacturing compliance, sourcing, and value. If a product fails any part of it, we don’t sell it.
