Noticeable Mental Acuity Improvement with No GI Distress
I have been consistently using Doctor's Best Brain Magnesium L-Threonate with Magtein (150 mg, 60 count) for several weeks. As I have been impressed with the results and the overall quality of this supplement, I felt it was time to write a review. The main advertised feature is the support of cognitive function using the patented Magtein formula (Magnesium L-Threonate), which is specifically designed for better brain absorption. After several weeks of daily use, I can say I feel an improvement in mental acuity and focus. It has become a part of my daily supplement regimen because of these benefits. Unlike some other supplements, I've experienced no negative side effects or the common magnesium-related GI upset. The product is very easy to incorporate into a daily routine. The recommended dosage of two capsules daily is clear and easy to follow. The gelatin capsules are easy to swallow for me, (though I have seen this mentioned as a drawback in other reviews) and have no residual taste or aftertaste. Every time I have ordered, the product has arrived with excellent packaging and a secure safety seal. Pros: Noticeable Cognitive Boost: Helped significantly with mental acuity and focus. Highly Absorbable Formula (Magtein): Effective at crossing the blood-brain barrier. Zero Side Effects: Has not caused me any gastrointestinal (GI) distress. Excellent Quality: Arrives consistently with secure packaging and safety seals. Cons (Area for Improvement): Cost/Value: The one major drawback for me is the price point. While the product's performance and quality are excellent, it is a bit expensive compared to other supplements. I wish it was sold in a larger size (e.g., a 90 or 120 count bottle) or offered at a better price per capsule, as this would make long-term use more economical. I would recommend this product to anyone looking to support their focus and mental clarity, especially if they are sensitive to other forms of magnesium. This may be a case of getting what you pay for ie., a premium supplement that has shown results for me.

Absorbs quickly, taste great.
Powder absorbs quickly and the fruit punch taste is not overly sweet. Great product and seems to take effect quickly. Take it every night to go to bed and feel the effects within 30 to 40 mins

Legs no longer cramping our style.
My wife developed nocturnal painful leg cramps and began taking magnesium tablets to mitigate them. We are both seniors, and I developed some as well, so I figured I'd give the pills a try. Two problems: one, it takes the pill a good while to get into your system, so you have to take it around dinner for it to kick in by bedtime. Two, the pills are like trying to swallow a golf ball, with advanced age one's mouth and throat dry out some, so you have to drink a lot of fluid to swallow it. So we decided to try this powder, and it was truly a game changer. First, we take it at bedtime, and it greatly decreased the frequency and severity of our leg cramps, and actually most older adults are magnesium deficient anyway. You mix a small, measured portion (scoop included) into a small amount of water. This part sounds gross, but it's helpful. When you dump the powder into the water it turns the water blue, and as you stir it the color changes to orange, so you can visually monitor how successful your stirring was. It tastes pleasant, much like orange juice and no pills to try to get down. It's a bit expensive, but one jar for two will probably last six weeks of daily use. We are hooked, good supplementation, virtually no leg cramps, easy swallowing at night, a quality product.

Sleep fantastic without cramps.
Take this about 30 minutes before bedtime. Taste delicious I actually enjoy this bedtime treat. I sleep good and rarely wake up at night since starting this product. My fingernails are definitely thicker so hopefully my bones are as well. I did start out slow with a half a scoop and quickly worked my way up to two scoops. Statistics show 80% of older adults are deficient of magnesium. I’m sure young adults who overindulge in bad habits are deficient as well.

Novel form of Mg, exercise caution re dose and large capsule size
I am continuing to research and review forms of magnesium. I believe Doctor's Best may be the highest quality product I can purchse through Amazon. Magnesium L Threonate (MLT) is a novel form of magnesium.. The bioavailability via the Blood Brain Barrier may be exceptionally therapeutic for some and may prove problematic for others. As with all electrolytes, patients should be aware of problems related to elevated Mg levels (hypermagnesemia). Magnesium levels may need to be measured via blood tests given certain medical conditions as well as keeping a log of energy, mood and sleep. There are far fewer professionals/providers with the knowledge or willingness to moniter and advise than there are patients taking supplements. I had a conversation recently with a neuropsychiatrist regarding the promising studies of MLT for a number of issues but was warned of the potential for increased anxiety (mania). Supplements are a highly unregulated industry and we often take them as "drugs" for therapeutic responses as big pharma products without all that goes into making a drug as safe as possible (at a profit, of course). Not getting into that discussion; just saying.... I subtracted one star for the very large size capsule. I have problems swallowing this large product. I need to take them carefully, individually and with the right fluid+volume as well as proper head/neck position to be sure it does not lodge in the pharynx(back of throat)/throat/epigastric (lower esophagus to stomach entry) area. I take a wide variety of supplements and medications by the handful without incident. This is the most difficult for me to take. I have had to use choking "Heimlich maneuver"s or addtl food/beverage to dislodge from a panic feeling or push the capsule to drop free into my stomach. I have considered buying smaller gelatin capsules to divide this into a size I can handle (PIA). I continue to look for similar high quality MLT sold in smaller mg/caps. The episodes are very unpleasant.

Many benefits
Great taste, works very well for me, a warm cup in the evening has made a big difference in the muscle cramps I use to get after yard work! I believe I sleep better also! I’ve tried the gummies and capsules but I don’t take them regularly so this is perfect. I’m trying to lose some weight and this also is a benefit to keeping me regular, and

Unappealing taste
I'm sure the product is decent quality, but I just can't get past the unappealing flavor. Too bad. So I avoid taking it.

Doctor's Best has great products
I was going to give this two weeks before I review, but my husband and I noticed it right away that it was helping. So maybe it's because we also take another brand of magnesium that we have some level of that in our bodies anyway. Regardless, our minds seem much clearer and a little sharper. I have read to give it two weeks, but we started this on the 21st, so I'll try to update later after several weeks. Here's the only thing. Doctor's Best has great products, but this is a bit expensive for us. We are both older, and we also take other things as well, so that is always money out of our pockets. Next time we're trying another brand that has excellent ratings on it like Doctor's Best, but there is more of it. We're going to try that next. If it doesn't work as well, we'll come back to this product because we already know it's good. I already take other Doctor's Best supplements, and I know how well they work. Too bad some companies don't have a senior citizen discount. That would help. Well, I know some do, but most do not have that. 2/3/2015: I've updated, but for some reason my update didn't go through. What I wanted to say is that I have insomnia, and just about a week ago have started sleeping better than I have in years. I'm thinking that it may be this product, plus it is seeming that I am sleeping much deeper. Not only that, I woke up Sunday morning and was feeling great, so much energy. Guess this stuff is working in more ways than just our brains.
