        Frequently Asked Questions

        Whether you're new to enzyme supplements or a longtime customer, we've compiled answers to the questions we hear most often. From product information and pricing to shipping and returns, you'll find helpful information below to make your experience with Express Naturals as smooth as possible.

        Why do I have to email to see your best prices?

        Some of the brands we carry require retailers to follow Minimum Advertised Price (MAP) guidelines, which restrict the prices we can display publicly. Click on an orange button above any product and you'll receive instant discounts, special pricing, and promotional offers that may be available.

        Are your products guaranteed?

        Yes. We stand behind every product we sell with a 30-day money-back guarantee. If you're not completely satisfied with your purchase, contact us and we'll work to make it right.

        How do you ship and what is the cost?

        Orders are shipped via USPS Priority Mail and typically arrive within 2–4 business days. Shipping is always free in the United States. During major holidays, delivery times may be slightly longer.

        Where are your supplements manufactured?

        Manufacturing locations and facilities vary by brand and product. We source genuine products from the manufacturers we represent and follow each brand's current product and quality information.

        Do you match prices?

        We work hard to offer competitive pricing on all of our products. If you find the same product available from an authorized retailer at a lower price, contact us and we'll do our best to match or beat it.

        How do I know which enzyme supplement is right for me?

        Each product has a different formula, ingredient profile, capsule format and label directions. Review the product descriptions and labels to compare your options, or contact us with product-specific questions.

        When will my order ship?

        Most orders placed before our daily cutoff time ship within one business day. You'll receive tracking information as soon as your order is on its way.

        What if my enzymes are left in a hot mailbox or vehicle?

        Brief exposure to warm temperatures during normal shipping is generally not a reason for concern. Store enzyme supplements according to the directions on the product label once received.

        If your order has been exposed to extreme heat for an extended period or you have concerns about its condition, please contact our customer support team.

        Do I take systemic enzymes with food or on an empty stomach?

        Systemic enzyme products are generally directed to be taken with water on an empty stomach, away from meals. Timing can vary by formula, so always follow the directions on the specific product label.

        Can systemic enzymes go bad?

        Enzyme supplements have expiration or best-by information provided by the manufacturer. Store them in a cool, dry place and follow the storage directions on the product label. If you have questions about the condition or age of a product, contact us before using it.
