The forgotten mineral

Everyone talks about calcium, and that is great but in many ways magnesium is even more important. So this Nutrivein Magnesium L-Threonate (Magtein) 2207mg - Boosts Brain Health, Memory & Focus, Sleep & Recovery, Reduces Fatigue - 30 Day Supply (90 Capsules, Three Daily) is a great idea. Magnesium leads to better sleep, stronger bones, and reduce inflammation. Magnesium is pretty safe but don't take over 350 mg/day for adults and children ages 9 and up. So take just three of these a day. The front label mentions 2207mg as a dose, which would be dangerous, however, it suggest three capsules for 200mg, which is fine.

Loved this product. I think I can feel the difference.

Good product

Much better sleep than before

Every since I started taking this type of magnesium much better quality sleep than before. I had no GI issues with this this brand. Does it make me feel smarter, haven’t seen that yet.

Three capsules per dose

They advertise this for brain function, and which it can help with that I mainly take it for sleep. I have issues sleeping at night and I find while taking magnesium that it does seem to help some. I’ve always been told the best way to get magnesium into your system is through your feet soaking them in a magnesium bath/Epson salt. Or magnesium sprays. I’ve been using this type of products for years and it definitely helps. This is magnesium in a pill form. It seems like it may be working just about as well as my other method. It does seem to help some with my sleep. This one recommends three capsules per day as they are a fairly low-dose. Overall does not seem like a bad product but still may not be my first pick. Magnesium can cause diarrhea if you get too much in your system. If you do notice these negative side effects back off on the number of pills you take until your body adjust.

I'm am an avid believer and user of supplements, but reviewing them is problematic, and my results may not be your results for these reasons: 1) I am not a laboratory scientist, I do not play one on tv, nor do I know one, so who knows what’s exactly contained in them. 2) It is difficult for consumers to see any actual difference in how you feel within a few days to a couple of weeks. Some supplements take as much as ninety days to see results. 3) Even if we do notice a difference, we all take other meds or supplements that may affect our results one way or the other. 4) We all have different physiologies, and are just different in so many ways (lifestyles etc). But we can hope for the best when we see others having positive actions going on, that are attributed to said supplements. So my personal non doctor opinion of my own results: Very high level of absorption and mg in this supplement. Very pleased with the results as I am a migraine sufferer
