Grape Seed-100

DaVinci® supplements are manufactured in the US with high-quality, researched ingredients sourced domestically and from around the world. Our products are manufactured in an SQF-certified facility that strictly adheres to Current Good Manufacturing Practices (cGMP) as outlined by the Food and Drug Administration.

We use high-quality ingredients sourced in the U.S. and globally. Regardless of their origin, all our ingredients undergo extensive third-party testing to ensure their safety, purity, and efficacy. We pledge truth in labeling and are committed to transparency regarding the ingredients used in our products.

No, a prescription is not required to purchase DaVinci® supplements. They are available for our website, other online retailers, and through select healthcare practitioner clinics.

DaVinci® supplements can often be administered simultaneously. However, we always recommend consulting with your healthcare practitioner to determine if a combination of supplements is suitable for your unique health needs.

Increasing the dose is not recommended unless specifically noted on the packaging or advised by your healthcare practitioner.

DaVinci®, like many companies, is required by the state of California to include this warning on some of our product labels. This is because some ingredients used in the product may contain trace amounts of certain naturally occurring chemicals, like lead, that are found in soil. Therefore, they require a Prop 65 warning based on California's regulations. These products are considered safe for daily intake.
