21st Century Health Care, MgO, Magnesium Oxide, 400 mg, 90 Tablets12 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

MgO 400 mg (Magnesium Oxide)
Necessary for the metabolism of calcium, vitamin C, phosphorus, sodium, and potassium. Magnesium is essential for nerve and muscle function , and for converting blood sugar to energy. Ninety percent of Americans don't get enough magnesium in their diets. Certain prescription drugs such as loop and thiazide diuretics, cisplatin, cyclosporine and antibiotics may deplete magnesium.

iHerb Customer Reviews
That's an interesting negative review but I liked this product and it works well for the use intended. Great for neck and leg cramps. It also is good for your bones, heart and keeping your body cleaned out.
I've been on magnesium for a few years because of my migraines. One of the side effects I've had to deal with is an upset stomach. My specialist recommended trying magnesium with oxide to alleviate the stomach issues and it worked like a charm. This was the first magnesium I tried that didn't cause any problems. I highly recommend it.
