I tend to get a bit overstimulated on a daily basis. In the past it’s been hard for me to fall asleep. This magnesium glycinate has been a fantastic tool for helping me with winding down in the evening. I like that when I wake up, I don't feel groggy as one might with sleep medications. I’ve been a fan of NutraBio for well over a decade now and excited to be seeing them get into the micronutrient supplement market. Definitely worth a shot if you are looking for a solid magnesium product to help wind down. Great value for high quality magnesium.

This is a high quality magnesium glycinate supplement. I like that they are using Albion magnesium bisglycinate, which is one of the main brands I look for with magnesium. The full 350 mg elemental magnesium is right in the range I like to see, and from a formulation standpoint this is doing the main thing right. The only real downside is the 4 capsule serving size. That is a little more than I would personally prefer for something this simple, especially when some other magnesium glycinate products can get similar dosing in fewer capsules. The added 5 mg BioPerine is fine, but it is not really the main reason to buy something like this and doesn't make a meaningful difference in absorption. Glycinate is usually easy on the stomach, and 350 mg is enough to be a meaningful dose for relaxation and sleep support. I take 4 capsules an hour before bed and it definitely improves my sleep quality and helps me fall asleep a bit quicker. Overall this is a really solid magnesium glycinate with the right form and a meaningful dose. I would personally prefer fewer capsules per serving, but the Albion form and full dosing make this a good product. All that said, at just 30 servings per bottle, it's not a great value compared to tablet form of Albion magnesium.

This is the recommend type of magnesium you should be taking if you’re looking for maximum absorption, along with improved sleep at night with no grogginess in the morning. I notice when I miss even a single night of taking this supplement, I experience a muscle cramp the next day at some point, so it definitely helps with that if you have issues with muscle cramps. As far as sleep improvement, it’s better than any sleep supplement I’ve taken before… everything I’ve taken in the past has made me at least somewhat groggy in the morning, no matter how low I make the dose. With this supplement however, using the maximum dose really helps me to fall asleep fast and with absolutely no grogginess when I wake up. Would highly recommend.

I'm not a fan of swallowing pills or tablets, so I try and find powder or chewable alternatives whenever possible. I ordered this magnesium because it was available as a powder and didn't have any added flavoring or sweeteners. I appreciate that the jar had a tamper evident seal on it. The product also seems fresh, with an expiry date almost 4 years out! The included scoop makes for easy measurement. The suggested "serving size" is 1 scoop a day, with 50 servings in a jar - so enough to last 50 days. The scoop isn't very large, so you aren't trying to dissolve a huge amount of powder. The powder is also nice and fine. I haven't had trouble dissolving it in in a variety of liquids. The powder dissolves pretty quickly and easily and seems to dissolve pretty completely, as I haven't notice it reaccumulating at the bottom of the glass as I drink. I also don't notice any grittiness from this powder. I like that this powder doesn't have any added flavoring or sweeteners. I appreciate that this powder is unflavored and haven't noticed it to alter the flavor of any of the drinks I've mixed it with. It also hasn't caused any stomach upset, bloating or other noticeable side effects. Overall, this product is easy for me to use and tolerate and I feel it is a good value for the money.

Sleep is crucial for a healthy and functional body and lifestyle, ranking high on the food chain next to exercise. Magnesium glycinate, a supplement known for its sleep-promoting properties, also offers other health benefits like supporting heart health and relieving muscle cramps. As we age, these factors become more concerning, and having a supplement to alleviate or eliminate the adverse effects of our bodies fighting us is a significant advantage. Taking this supplement in powder form makes it easier for seniors to establish this as a habit rather than a chore. The powder is easy to consume, with minimal to no flavor, allowing you to easily incorporate it into any flavored drink or smoothie. However, this option comes with a higher price point due to its convenience, compared to a capsule version. Ultimately, the decision depends on your lifestyle, convenience, or cost considerations. Regardless, the health benefits make it worth trying.

Magnesium Glycinate is specifically bound to the amino acid ​glycine​, which has its own calming effect on my brain. This makes it significantly more effective for my sleep and anxiety than "Mag Citrate" or "Mag Oxide. NutraBio is famous for its ​Full Label Disclosure​. They don't use proprietary blends and I actually entered the lot number from my jar onto their website, ​CheckMySupps.com​, to see the third-party lab results for that exact batch.​​ Because the magnesium is "chelated" (wrapped in amino acids), it bypasses the typical laxative effect associated with magnesium. It is an excellent choice for me with my sensitive GI tract as I still need nighttime muscle relaxation.​ The powder is exceptionally clean. It contains no "flow agents" like magnesium stearate or silicon dioxide, which are common in capsule versions. It is non-GMO, gluten-free, and vegan-friendly.​ Being a standalone powder it was easy for me to stack my other nighttime nutrients like L-Theanine or Tart Cherry without overdoing my total pill count.​ I found for the best sleep results taking my serving about ​30–60 minutes before bed​ worked best. What also helped me was I found the unflavored taste too "earthy" so I mixed it into a cup of warm chamomile tea and the heat helped the powder dissolve even faster.​ You may have to dig for the scoop.

My husband and I started making the "cortisol cocktail" that became really popular a few months ago. I usually have massive digestive issues with magnesium supplements in pill form. I had hoped that a powder would be better, and turns out it is. The biggest issue we have had is that most magnesium glycinate powders have a strong aftertaste (often ranging from a fishy taste to a mineral-y taste). Some have been really gritty, too. NutraBio is not gritty, but it does still have an aftertaste that's kind of difficult to describe (but it's definitely not fish). The aftertaste is the reason I take off a star. I appreciate that it mixes in with the other ingredients seamlessly. We have our cortisol cocktails in the evening, and neither of us have trouble with our digestive systems. It does seem to be helping with better sleep, so I'm super grateful for that.
