Deal Details
YMMV: My in store base price was $17. After $4 rebate the final price was $13. This linked Costco page shows "$4 manufacturer's savings is valid 4/6/26 through 5/3/26", but I suggest you purchase from the store for a better deal.

The nutrition labels says 240mg, but this is from a total of 2 capsules. So each cap contains 120mg.

FYI I was in the market to help with sleep but ultimately the one I had used before from Walmart was cheaper. Qunol Mg Glycinate 120 caps for $13. I think you need to take >200 mg and each cap base 210 mg thus 120 supply for $13 rather than 90 day supply here.

NB is a good brand though so either is good.
