Description

Highly Absorbable Form Supports Healthy Muscle, Nerve & Heart Functions Magnesium glycinate utilizes magnesium bound to the amino acid glycine, which facilitates intestinal absorption. Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. It is a required cofactor for an estimated 300 enzymes. Among the processes that require magnesium are fat and protein production, as well as glucose metabolism. Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland. Natural color variation may occur in this product.

Gentle, Effective, and Easy on the Stomach
Flavor Name: Unflavored Size: 180 Count (Pack of 1)
I’ve had a great experience with this magnesium glycinate supplement. The capsules are easy to swallow and gentle on the stomach. I like taking it in the evening because it helps me relax and supports better sleep. The quality is excellent, and NOW Foods is a brand I trust. There is no unpleasant taste, and the bottle provides a good supply for the price. Overall, this is a high-quality magnesium supplement that is effective and offers great value for money. I would definitely purchase it again. ... show more

No More Nighttime Leg Cramps
Flavor Name: Unflavored Size: 180 Count (Pack of 1)
This magnesium glycinate has helped my nighttime leg cramps so much. After taking it consistently, I noticed a huge difference in how often I was waking up with painful cramps, and now I’m finally sleeping much more comfortably through the night. I specifically chose the glycinate form because it’s known for being gentle and highly absorbable, and I’ve had no stomach issues or unpleasant side effects with it. The tablets are easy to take, and the quality feels consistent like I expect from NOW Foods products. I also noticed I feel more relaxed overall at night, which has been an added bonus. The large bottle lasts a long time too, making it a really good value for a high-quality supplement. Overall, this has become one of my staple supplements and has made a noticeable difference for muscle cramps and nighttime comfort. ... show more

Highly recommended!
Flavor Name: Unflavored Size: 180 Count (Pack of 1)
This was not my first time buying Magnesium Glycinate from NOW, and I wanted to share a layperson’s perspective, since most of us who buy supplements aren’t medical experts. I chose NOW because it’s one of the most reputable supplement brands, even though their products tend to be more expensive. The packaging and overall presentation are excellent, and the product seems to be very high quality. They claim it may help regulate blood sugar and blood pressure, potentially reducing the risk of heart disease, stroke, and diabetes. These are things that are hard for an average consumer to evaluate. But they also mention reduced anxiety and improved sleep quality — and that’s where I personally noticed a real difference. In the very first week, my sleep improved significantly. I fell asleep much more easily and slept longer. Before taking Magnesium Glycinate, I usually slept 4–5 hours a night; after starting it, I began sleeping 6–7 hours, and occasionally even 8. For me, that alone made the supplement worth continuing. I also experienced no side effects such as diarrhea, nausea, or abdominal discomfort. Overall, an excellent product. Five stars. ... show more

Natures ambien Natures ambien
Flavor Name: Unflavored Size: 180 Count (Pack of 1)
I’ve been taking this magnesium for over three years now, starting during my pregnancy when I stopped ambien because I didn’t want to continue it while expecting. I never went back to ambien, even though I had been using it for several years and I never thought I’d be able to get a full nights sleep without it. For me, this has been the best sleep support I’ve found that actually works and I’ve tried soooo many things. I take two each night, and it really helps me relax, calm nighttime anxiety, and wind me down so I can fall asleep more easily. I’ve also noticed my skin looks clearer and I seem to have fewer breakouts, although I can’t say for certain if that’s directly related. I recommend this to everyone in my life when they tell me they have insomnia or a hard time sleeping. It’s become a simple but essential part of my nightly routine. The only downside is that I can’t find it locally if I run out so I do wish shipping were a bit faster though that’s probably on me since I tend to reorder when I’m down to my last few. ... show more

Good quality; big size.

No gut issues with this. The only downside is the size of pills.

Worked well
Flavor Name: Unflavored Size: 180 Count (Pack of 1)
Just started taking it after getting a real hurtful muscle cramp, I’m actually used to taking the citrate but a friend gave me one of this particular one for the muscle cramp and by the time it hit my tongue the cramp was gone. So my review is based on that, because the citrate worked exceptionally well for me too in terms of sleeping well, no constipation, or muscle cramp either. I.E I’ve always liked and trusted the NOW brand ... show more

Gentle and Easy to Take
Flavor Name: Unflavored Size: 90 Count (Pack of 1)
I’ve been happy with this magnesium supplement so far. The tablets are easy to take and the glycinate form feels gentler on my stomach than some other magnesium supplements I’ve tried. Simple, good quality product and convenient for daily use.
