Very pleased with my order!

The item is as was expected, the service was immaculately speedy, I will be ordering from Bulk Supplements again, altho it will be a while before ordering this again . . . I ordered the second biggest size and it will last me at least a year. I didn't realize that, unlike the pills I have purchased in the past and taken like 4 at a time, this is much more concentrated and a little bitty portion of a spoonful is all that is needed.


I use this product every evening. Helps with digestion and elimination in the morning. I bought a similar product for years from a well known vitamin store. It was pretty expensive. Now I can make my own pills with the pill machine purchased from Bulk Supplements This makes it easier to take my magnesium when I travel. I've shared this product with friends who have similar issues and they were so impressed that they purchased their own. Great service and timely arrival of my order. .


I have ordered Magnesium Oxide several times. I like the fine powder and it mixes well with any liquid. I use it in the evening and it helps my digestion by morning. Not too harsh on my system. Because you don't need to take a large amount, this will last for several months. I transferred the powder to a small mason jar to make it easier for daily usage since the white pouches are difficult to close.


Bulk supplements has the best pure powder form at the best price, ordering is simple & delivery was lightning fast. I bought magnesium oxide powder to supplement a horse who is on high calcium alfalfa. Since it's tasteless, it's no problem to add to his grain, and even for a horse, a little goes a long way. I love that it's safe, so it's worth trying to see if it makes any difference in his muscle tension, etc.
