I've been taking this magnesium supplement for a few weeks, and I'm very happy with it. The capsules are easy to swallow, gentle on my stomach, and I haven't experienced any digestive discomfort. I especially like that it uses magnesium L-threonate, which is formulated to support brain health and cognitive function. I've noticed I feel more focused during the day and seem to sleep more soundly at night. The bottle offers a good supply, and the quality is what I've come to expect from Jarrow Formulas. If you're looking for a high-quality magnesium supplement, this is definitely worth trying.

Best Magnesium source!
Flavor Name: Unflavored
Size: 90 Count (Pack of 1)
I have tried many forms of Magnesium in the past, it’s an essential mineral for the body (regulates over 300 functions). It helps with sleep, blood pressure, cognitive function, mood, muscle cramps, and ATP production (the powerhouse of the cell). Science talk aside, I have tried Magnesium Glycinate and Citrate, and they can do a number on the gut, moving things along too quickly! Magnesium L-threonate has become very popular, but I am very picky about my supplements and the companies that make them. Jarrow Formulas is top notch! I have started looking for supplements that are more “bio-available” as they are better absorbed and used by the body. This supplement does all of the above, without upsetting my gut and making it overactive. I ran out of this supplement a few months ago, money was really tight, and it really affected my sleep, which is priceless! It also has L-threonate, which promotes sleep and positive mood. I am happy to have this back in repertoire, combined with vitamin D once a week (50,000IU), and Calcium Hydroxyapatite (see my other reviews, also super bioavailable). If you are looking for a Magnesium source that helps you sleep and regulate body functions without the side effects on your gut, this is a standout choice that works great!

Jarrow is a trusty brand, Magmind is superior for cognition, spatial relations and SLEEP QUALITY - UPDATED REVIEW
Flavor Name: Unflavored
Size: 90 Count (Pack of 1)
I have been using Jarrow Formula supplements for a number of years, especially the Vitamin B12 - methylcobalamin and Vitamin K2 - MK7 supplements. I have been impressed with their continuing development of new *effective* products at a great price point. My husband and I have been taking approximately a gram a day of supplement Magnesium (cheaper products) for almost 5 years now. In that time we have cured his former type 2 diabetes (after almost a 2 decade battle with medicated fasting BGs in the 500s at one point!) and we have almost completely reversed his hypertension of many years as well has have turned his end stage Severe Congestive Heart Failure around so he's relatively free of symptoms. I credit not only the magnesium, but also high doses of Vitamin D (ALWAYS taken with magnesium and fish oil!!), a whole foods source multi, the Sinatra Protocols for supplements as found in the back of The Sinatra Solution: Metabolic Cardiology and a number of minerals especially trace minerals as found in Liqumins ConcenTrace Trace Mineral Drops, Low Sodium, 8-Ounce Bottle. I was looking into research on magnesium and the brain when I ran into the MIT study published in 2010 showing magnesium L-threonate is the only form of magnesium to cross the blood-brain barrier and showed observable improvements in cognitive measures. Interesting. So we bought a bottle at our local neighborhood nutrition shop after a discussion with the owner, a couple I have come to trust during our many battles with the medical establishment. Jarrow Formulas of magnesium L-threonate as Magmind is a very cost-effective source. To further economize we are still taking our regular magnesium supplement 3 times a day (750 mg) then taking this form of magnesium as part of our bed time routine (replacing the 4th magnesium of the day). I am genuinely impressed. Our sleep has improved yet another notch, which is saying something since the 5 years of magnesium supplementation meant we already had really good sleep quality. What I have noticed is that after multiple head trauma injuries (including a serious concussion earlier this year) my previously very high level of spatial relations was slipping. Now with Jarrow I feel I'm getting that edge back. I am very impressed. I will update again with further results after we've been taking this formula longer. 2015 UPDATE - in the years since we first tried MagMind I've referred hundreds of people to try this quality supplement with great results. We've since learned to couple magnesium with taurine for even greater results. Taurine is VERY well documented to improve the fluidity of electrolytes within the cells including within the brain. NOVEMBER 2016 UPDATE: Well, here we are 4 years later. We still personally use and recommend MagMind. What we discovered though, since he was put on Armour Thyroid by our primary care he no longer seems to be "leaking" magnesium hence we've cut magnesium supplementation waaayy back. Plus we soak in epsom salts far more. Magnesium is still vital however we're no longer "taking a gram a day."

MagMind for Focus and Clearer Thinking.
Flavor Name: Unflavored
Size: 90 Count (Pack of 2)
I’ve been taking Jarrows Formula brand of Magnesium L-Threonate MagMind for close to 4 years now. I wish I’d found it when going through menopause. I then had a foggy brain and I struggled to focus and multi task. Which my job in sales required. I started with the required 1 capsule in the AM and 2 in the evening before bed. I noticed a difference probably half way into my first bottle. Clearer thinking and I slept better at night. Not a sleeping aid type of sleep. Just a noticeable “I slept” no morning grogginess. I then reduced my dose to just the two in the evening and my brain works as it should. I am 67 years old and I volunteer 2-3 days a week and my brain is keeping me sharp. I’ve also researched Jarrows Formula and this is what I’ve found and I personally feel comfortable with. “Jarrow Formulas is a long-standing, heavily science-backed dietary supplement brand founded in 1977 in Los Angeles, California. The brand is highly regarded by health professionals and consumers for its focus on peer-reviewed clinical research and ingredient bioavailability. Quality and Purity Testing: Jarrow utilizes certified independent, third-party laboratories to rigorously test every batch for identity, potency, and purity. Products are thoroughly audited to ensure they meet strict standards and are free of contaminants like pesticides. Manufacturing Standards: Products are mostly manufactured in the USA in state-of-the-art facilities that adhere to current Good Manufacturing Practices (cGMP) mandated by the FDA. Magnesium L-Theonate Scientifically Claims to Reverses Estimated "Brain Age": A prominent claim backed by a 6-week randomized, double-blind, placebo-controlled human trial shows that supplementation with 2 grams daily can result in an estimated 7.5-year reduction in brain cognitive age by improving reaction times and cognitive vitality.I truly believe this 100%. I believe in this so much, my 83 year old healthy walks 3 miles every morning has asked me to order some for him. I’m ordering the 2-90 ct bottles. One to share. There are several types of Magnesium. Do your research on what each type benefits.

It works!

I am going on my third month of use. It works!!!! I noticed a changes to my mood within a couple of weeks. Less quick to anger or get upset. After a month or so my reaction to everything became faster. I thought and acted, just faster. After about 2+ months, the walking into a room and forgetting why I went in there was gone! And for the record I just turned 77.

Chill pill 😎
Flavor Name: Unflavored
Size: 90 Count (Pack of 1)
I call this my chill pill. It worked for me pretty quickly but took a few days before I noticed a big change. Eases my anxiety and Helps keep me calm during stress. Also great to help moodiness associated with PMS. I will never go without this. I learned that I can back off on the dosing once it builds up in my system. So if I forget a day (or several) I still experience the effects of the magnesium. Now, if I stop taking for more than a week, I can start feel that I need to make sure I'm taking it. In the beginning, I took more per day but now I am just taking one nightly before bed. Sometimes will purposeful skip a night or two so I don't have to buy as frequently. While it may help me with sleep, I can't say I sleep better or worse since taking it. MY purpose for taking it is simply because it makes me a happier person. Personally, I am going to experiment with a different type of magnesium for sleep. If you are someone who has trouble sleeping because of anxiety or just has trouble relaxing, it may help. But this does not help relax me to feel tired and actually fall asleep. The pill is easy for me to swallow. It's probably important for me to say that I usually don't have trouble with taking supplements so I'm not picky. It does go down smoothly because of the capsule it is in. I recommend for people who are looking for something to help calm their mind from as much worry and help keep calm during normal everyday stresses.
