General GI Support

Easy-to-use soluble fiber formula to help maintain regularity and balanced GI flora*

We are very happy to announce that Formula SF722 is back in stock! 

Formula SF722 has been a best-selling Thorne Research product for over 20 years and we regret not having it available for you recently. This formula is in a softgel, which is manufactured for us by a contract manufacturer that also makes other softgel products for us. Softgel manufacturing requires unique equipment and expertise, which is why there are only four softgel manufacturers in all of North America. While preparing to manufacture a batch of SF722 three months ago, quality control testing revealed the presence of pesticide residues. This was investigated and it was found that the olive oil that was to be used in the product was the culprit. The olive oil was re-sourced, the product was put back into the production schedule, it was manufactured, re-tested, and we are very pleased to have Formula SF722 available again.
