Right now, you can save $10 at JigsawHealth.com. Or, you can get FREE Shipping. Jigsaw Health offers premium dietary supplements, with a special focus on Sustained Release Technology (SRT) that controls the release of active ingredients (i.e., magnesium, vitamin c, vitamin b) so absorption happens over time — as the body requires — instead of all at once. In five years, we're proud to have served over 40,000 customers. We don't force customers into an auto-ship program like many other dietary supplement companies. Simply put, our customers love our products.
