Source Naturals Magtein 90 Capsules

Definitely helped with calming mind & with focus. Check seller ratings before buying. Bit on the costly side due to the import premium.

Amazing results and delivery to the brain. Very good for cognition and increase of focus and productivity.

Effective but very costly

Excelente producto para mejorar la memoria

So, you try a supplement which is supposed to help your brain and your memory, but you know in the back of your mind that it won’t. But guess what? This one did! I started remembering things I forgot that I knew. Even little details! I was taking it for about three months when it dawned on me that I was having this memory recall. Definitely worth buying. As an added bonus, it helps keep your digestion regular because it’s magnesium.

This is an excellent product. It passes the blood/brain barrier. Helps generally and in preventing headaches.

A little google research will turn up a number of articles alleging that 70-80% of Americans are now deficient in magnesium, due to changes in diet (less consumption of leafy green vegetables, etc.) and so-called "corporate farming methods" that have depleted the soil of this essential mineral. There are a number of critical benefits to supplementing with magnesium, which including bone health, by balancing out calcium (there are plenty of studies now showing that calcium can't be absorbed properly without magnesium), moderating heart and blood pressure risks, neurological - improving sleep and concentration, preventing migraines, etc. It's quite a list. I started getting magnesium for our household to address some anxiety and restlessness issues, as well as some muscle cramps, and it _appears_ that the supplements we've used have had the desired effect. You can find the NIH fact sheet on magnesium linked here: http://ods.od.nih.gov/factsheets/Magnesium-HealthProfessional/ Turning to this supplement: there are various types of magnesium supplements that you can buy, including magnesium oxide (low bioavailability), magnesium sulfate (think Epsom salts), magnesium citrate (decent bioavailability), magnesium bisglycinate (high bioavailability) and magnesiums l-threonate. Of these types, I've used bisglycinate (as in the Viva labs pills and others) because of its high bioavailability and source naturals l-threonate because of its documented neurological benefits in improving brain function. I tend to steer away from others because, despite being less costly, they are also less effective. You get what you pay for, to a degree. I certainly would never consider a magnesium oxide supplement, as in my opinion that's basically a waste of money. The Viva Labs magnesium comes in the form of 240 decently large, but readily swollowable, chelated tablets. They're somewhat larger than the Source Naturals L-Threonate capsules that I'm currently taking, and the Viva Labs tablets are bit harder to get down, but not so large that it's a problem for me. I can't tell the difference when I switch between them, to be honest. That said, when I started taking the Magtein, I found I slept much better and started having some fairly intense dreams - this has continued while taking the Viva Labs magnesium, so I assume the absorbtion is at least somewhat comparable. As far as price - the Magtein is far more expensive then Viva Labs chelated magnesium, although I think it's the cheapest of the L-threonate magnesiums - currently listed at $21.69 for 90 capsules, or 24 cents each. The suggested use is 2 in the am and 1 at night - 3/day or 72 cents a day. Viva Labs is listed at $18.99 for 240 tablets, or approximately 8 cents each. the suggested use is 2 tablets twice a day, for a cost of almost $.32/day. Simply put, the Viva Labs magnesium costs less than half of the Source Naturals L-Threonate magnesium. That doesn't mean it's necessarily the right choice - I think everyone should do a little research and also decide exactly what they are trying to accomplish. Source Naturals L-Threonate might be the right choice to help with memory and neurological issues - Viva labs might be desirable for coronary issues, muscle relaxation, and teeth and bones. Regardless, I suspect both these products work well, albeit possibly to different degrees, and both of these products are worthy of consideration.

These supplements help me understand things better. And go to the bathroom better. Thanks.
