## Description

Doctor’s Best Brain Magnesium contains Magnesium L-Threonate from Magtein, a unique magnesium compound that helps support the health of neurons and synaptic plasticity.

Magtein performs better than other magnesium compounds for synapse support and is a breakthrough in brain health.*

Review: 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.
Review: 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.
*by A***R on October 30, 2025*

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.
