Terms of service

Last updated: October 2026

1. About These Terms

This website, lignans.com, is operated by Lignans for Life LLC, a division of TSKG Products LLC ("Lignans for Life," "we," "us" or "our"), 120 South St, Hopkinton, MA 01748, United States. By browsing this website or placing an order, you agree to these Terms of Service, together with our Privacy Policy, Shipping Policy and Refund & Return Policy. If you do not agree, please do not use this website.

2. Not Medical or Veterinary Advice

Our products are dietary supplements for people and pets. Information on this website, in our blog articles and from our customer service team is provided for general educational purposes only. It is not medical or veterinary advice and is not a substitute for advice from your physician or veterinarian. Always consult a qualified professional before starting any supplement, especially if you or your pet are pregnant, nursing, taking medication or have a medical condition.

Statements on this website have not been evaluated by the Food and Drug Administration. Our products are not intended to diagnose, treat, cure or prevent any disease. Individual results vary.

3. Products, Pricing and Availability

We make every effort to describe our products and display prices accurately. However, errors may occasionally occur. We reserve the right to correct any error in pricing, descriptions or availability, and to cancel or refuse any order affected by an error, even after it has been placed. Prices and availability may change without notice. Product images are for illustration; packaging may vary.

We may limit quantities or decline orders at our discretion, including orders that appear to be placed by resellers without a wholesale agreement.

4. Orders and Payment

When you place an order, you confirm that the information you provide is accurate and that you are authorized to use the payment method. Your order is an offer to purchase; it is accepted when we ship it. If we cannot fulfill an order, we will notify you and refund any amount charged for the unfulfilled items. Sales tax is charged where required by law.

5. Subscriptions

Some products are available on a recurring subscription ("subscribe and save"). By choosing a subscription, you authorize us to charge your payment method automatically at the frequency you select, at the subscription price in effect at the time of each order, until you cancel.

• You can skip, change or cancel your subscription at any time through your customer account or by contacting us. Cancellations must be made before your next order is processed to avoid that charge.
• We may change subscription pricing or discounts with advance notice. You may cancel if you do not agree to the change.
• If a payment fails, we may pause or cancel your subscription.

6. Shipping, Returns and Refunds

Shipping methods, rates and delivery times are described in our Shipping Policy. Returns, exchanges and refunds are governed by our Refund & Return Policy. Return shipping costs are the customer's responsibility. International customers are responsible for any customs duties, taxes and import restrictions in their country.

7. Wholesale Customers

Wholesale purchases are subject to approval and to the separate wholesale agreement provided at sign-up. Where that agreement conflicts with these Terms, the wholesale agreement applies.

8. Your Account

You are responsible for keeping your account login secure and for activity under your account. Please notify us promptly of any unauthorized use.

9. Reviews and Content You Submit

If you submit reviews, comments or other content, you grant us a non-exclusive, royalty-free right to use, display and share it in connection with our business. You agree not to submit content that is false, unlawful, offensive or that infringes anyone's rights. We may remove content at our discretion.

10. Intellectual Property

All content on this website, including text, images, logos, product names (including Lignans for Life, K9 Select and Kitty Cat Select) and design, is owned by or licensed to us and protected by copyright and trademark law. You may view and print pages for personal, non-commercial use. You may not copy, reproduce or republish our content without written permission.

11. Prohibited Use

You agree not to misuse this website, including by attempting to gain unauthorized access, interfering with its operation, scraping content beyond what our robots.txt permits, or using it for any unlawful purpose.

12. Third-Party Links

13. Disclaimer of Warranties

This website and its content are provided "as is" and "as available." To the fullest extent permitted by law, we disclaim all warranties not expressly stated in these Terms, including implied warranties of merchantability and fitness for a particular purpose. We do not warrant that the website will be uninterrupted or error-free.

14. Limitation of Liability

To the fullest extent permitted by law, Lignans for Life will not be liable for any indirect, incidental, special or consequential damages arising from your use of this website or our products. Our total liability for any claim relating to a product will not exceed the amount you paid for that product. Some jurisdictions do not allow certain limitations, so some of these may not apply to you. Nothing in these Terms limits your rights as a consumer under applicable law.

15. Indemnity

You agree to indemnify and hold Lignans for Life harmless from claims arising from your breach of these Terms or your misuse of this website or our products.

16. Governing Law

These Terms are governed by the laws of the Commonwealth of Massachusetts, United States, without regard to conflict-of-law rules. Any dispute will be brought in the state or federal courts located in Massachusetts, except where applicable consumer law gives you the right to bring a claim in your home jurisdiction.

17. Changes to These Terms

We may update these Terms from time to time. The updated version will be posted on this page with a new "last updated" date. Continued use of the website after changes are posted means you accept the updated Terms.
