May 2025 – 6′-Sialyllactose (6′-SL) Update
Dear GNEM/HIBM community,
I hope this message finds you well. The NDF executive team has been diligently researching options for patients to access 6′-SL from reputable and reasonably priced suppliers. We want to share some significant information we have gathered during this process.
As a non-profit organization, the NDF operates primarily through the voluntary efforts of its members who are dedicated to finding an effective therapy and sharing essential research with our community. It is important to note that there is no financial benefit to any NDF member from this initiative.
Regarding 6′-SL, we encourage you to explore options available globally and identify which supplement companies offer this product. While baby powdered milk contains 6′-SL, finding it in its pure form may require some effort. We recommend reaching out to various supplement companies for assistance in sourcing pure 6′-SL. Keep in mind that prices may vary, especially for high-quality products produced in reputable laboratories (such as in Germany or Denmark). Most pharmaceutical companies in different countries should be familiar with this product, so doing thorough research can yield valuable information.
Consulting with your doctor or pharmacist can also provide guidance in locating this supplement. We urge each of you to invest time and effort into this search and share your findings with fellow patients. By collaborating, we can work towards securing better prices and quality for everyone.
Additionally, be aware of extra expenses such as customs charges that may arise, as we have learned that some countries impose significant charges on products imported from the USA. Shipping complexities can also contribute to higher costs. We recognize that the price of 6′-SL can be a financial burden for many. For instance, a monthly cost of $200 can represent a substantial portion of a patient’s income. We hope that those who are in a stronger financial position may consider supporting fellow patients who are facing financial challenges. In the future, we aim to organize fundraising efforts to assist those in need around the world.
As most of you know, we have patients in over 50 countries with a wide range of financial situations. The NDF’s primary focus is on scientific research to find an effective therapy. We have worked to minimize our costs and direct all donations towards our goal of ending this disease. We kindly remind you all to consider supporting the NDF financially so that we can continue our mission.
As this is an orphan disease, fundraising is a significant challenge, and the support of you and your families is crucial. Rest assured, we operate with minimal overhead to maximize the impact of every dollar received. We are committed to our mission, especially since there is no government funding available. We rely entirely on donations, and our goal is to provide comprehensive support and information for patients, particularly those newly diagnosed.
Thank you for allowing us the opportunity to contribute to our community’s efforts to find an effective therapy.
NDF Board
