Refund policy
Our Promise
Every Lignans for Life and K9 Select product is third-party tested for potency and quality. Supplements can take time to show results; most customers see a difference within 2–4 months of consistent use.
Satisfaction Guarantee
If you are not completely satisfied with your purchase, you may return unopened products within 60 days of purchase for a refund of the product price. Original shipping charges are not refundable.
Exchanges
Ordered the wrong product, strength or flavor? We will exchange unopened, sealed products within 90 days of purchase. Our satisfaction guarantee does not cover ordering the wrong product, strength or flavor, or a change of mind; these are handled as exchanges.
Return Shipping
Return shipping costs are the customer's responsibility, including for exchanges. We recommend a tracked shipping service, as we cannot issue refunds or exchanges for returns lost in transit. Opened or unsealed products cannot be returned or exchanged.
How to Return or Exchange
- Contact us first at support@lignans.com or 480-899-0713 with your order number.
- Ship the unopened product to:
Lignans for Life LLC
120 South St
Hopkinton, MA 01748
United States - Refunds are issued to your original payment method within 5–7 business days of receiving your return.
EU Customers: 14-Day Right of Withdrawal
If you are located in the European Union, you may withdraw from your purchase within 14 days of receiving your order, without giving a reason. To do so, email support@lignans.com within that 14-day period with your name and order number.
We will refund your order total, including standard outbound shipping, within 14 days of receiving the returned goods or proof of return shipment. If you chose premium or expedited shipping, only our standard shipping rate is refunded. Return shipping costs are the customer's responsibility. This right does not apply to opened or unsealed health and supplement products, as permitted under EU law.
