Magnesium L Threonate, Magtein™, Sleep and Cognitive Support – High Absorption – Most Bioavailable Form of Magnesium – 2,000 mg – 100 Capsules

I received the order in very timely manner. I am happy about that. Since the product came just a day ago, I can't fully evaluate the benefits yet, but what is this Magnesium L Threonate Capsules (Magtein) – High Absorption Supplement – Bioavailable Form for Sleep and Cognitive Function Support known for, seem to be noticed to some degree already. I am going to update the benefits rating after some more time.

I’ve tried different magnesiums, this is the best one I found without any digestive issues. I sleep great! No leg cramps. I would definitely recommend this product.

Excellent product. As per the images and description in the ad. I recommend it to all buyers.

Seems to be a more readily usable by body.

We have been taking these supplements for over six months if not more. I struggle to know if they are working but I do have to say they don’t upset my tummy, they’re easy to take, and I have heard they are pretty legit. Hence I keep taking them. My doc is happy too.

Yes this is great . Take it at night and get a good nights sleep

Great addition to my daily routine, on pill before bed and i sleep like arock, Magnesium is an essential mineral for us old duffers!

Magtein is a great form of magnesium threonate because it easily passes through the brain's barrier for better absorption. It also has less laxative effect than others and is less sedative than magnesium glycinate, which is really best for nighttime as glycine is known for its calming and sedative effect.A woman needs 320 mg (DV) of elemental magnesium a day and men 420 mg (DV). Of course, we get some from our diet, but given the very poor quality of western food, most people are actually magnesium deficient. Ignore the 2000 mg or 5000 mg on labels because they are advertising only the amount of raw magnesium used. Do not be sidetracked by all of these companies who label their products with these high mg amounts. It is elemental magnesium that is the important number because the daily value needed is based on that figure and not the thousands of mg of base magnesium they state! In fact, most companies don't even list the amount of elemental in their products and many won't give it or they tell you the elemental is a percentage per gram of the raw magnesium weight. Seriously?As for this product, they do list it so kudos to them. Unfortunately, not everyone reads the label or understands that it is the elemental amount that matters. The elemental magnesium content in this product is only 144mg for the full 4 capsules. Which is fine if you take it as a sleep aid (again you are better off using magnesium glycinate) or just to boost your own magnesium. For those supplementing with a higher amount to get that full daily value, do the math on how many you need. For a woman to get her DV of elemental magnesium she needs to take 9 pills and men a whopping 11. Which means each bottle has only 11 servings for a woman and 9 for a man!If, like me, you are taking a medication that strips the body of magnesium, you will need higher doses. I take 400 twice a day so need 18 pills per day. This bottle only lasts me 5 1/2 days. Who can afford that? So, I take another brand with a higher amount of elemental magnesium and add 3 capsules (48 mg) of these per day to get the benefits of the magnesium threonate.Bottom line, this is a great product and a wonderful form of elemental magnesium. But only for those who need a small amount each a day. If you need more, then this is a very expensive product.I hope this helps those who are as confused as I was about the differences between each type of magnesium and how important it is to know the actual amount of elemental magnesium in each product. Thank you for reading this!
