I take these daily

My husband and I take this religiously every day, especially during cold & flu season. No taste, easy to swallow.

good value
Size: 180 Count (Pack of 1)
I cannot claim that these do or do not help. Aside from that, for the price and strength i bought these and they seem to be the most cost effective solution.

Best Magnesium source!
Flavor Name: Unflavored, Size: 90 Count (Pack of 1), Flavor Name: Unflavored, Size: 90 Count (Pack of 1)
I have tried many forms of Magnesium in the past, it’s an essential mineral for the body (regulates over 300 functions). It helps with sleep, blood pressure, cognitive function, mood, muscle cramps, and ATP production (the powerhouse of the cell).
Science talk aside, I have tried Magnesium Glycinate and Citrate, and they can do a number on the gut, moving things along too quickly! Magnesium L-threonate has become very popular, but I am very picky about my supplements and the companies that make them. Jarrow Formulas is top notch!
I have started looking for supplements that are more “bio-available” as they are better absorbed and used by the body. This supplement does all of the above, without upsetting my gut and making it overactive.
I ran out of this supplement a few months ago, money was really tight, and it really affected my sleep, which is priceless! It also has L-threonate, which promotes sleep and positive mood. I am happy to have this back in repertoire, combined with vitamin D once a week (50,000IU), and Calcium Hydroxyapatite (see my other reviews, also super bioavailable).
If you are looking for a Magnesium source that helps you sleep and regulate body functions without the side effects on your gut, this is a standout choice that works great!
