  • A product that has helped me over the years. Read my tip on how to use it to maximize efficiency.
Size: 240 Count (Pack of 1)
I’ve been using Nutricost Magnesium+ 420 mg for years now, and it’s made a noticeable difference in several areas of my health. Initially, I started taking it to help with muscle cramps and soreness after workouts, but I quickly realized it was also helping me sleep better. I wake up feeling more rested, with less muscle stiffness and tension. Magnesium+ has truly become a vital part of my daily routine. Pro Tip: I recommend taking is 30 minutes to an hour before bed to promote relaxation. Why I Like It (Quality, Value, and Benefits) 420 mg of magnesium per serving, which is the perfect dose for my needs, all in just one easy-to-swallow capsule. Magnesium Oxide and Magnesium Glycinate: This combination works well for me. Magnesium Oxide helps support digestive health and overall body function, while Magnesium Glycinate is known for being gentle on the stomach and highly absorbable. Glycinate helps with muscle relaxation and improving sleep quality without causing digestive discomfort, which I’ve appreciated. The quality of Nutricost is consistently excellent — non-GMO, gluten-free, and vegan-friendly, which fits my lifestyle and gives me confidence in the product. Affordable: For the high-quality magnesium you get, the price is very reasonable. Health Benefits (What Magnesium Does for You) Magnesium plays a key role in a number of important bodily functions, and I’ve noticed the following benefits: Muscle relaxation — Magnesium Glycinate, in particular, helps me relax after a long day or intense workout, reducing muscle cramps and tension. Better sleep — Magnesium helps calm the nervous system, and I’ve found it makes a big difference in my sleep quality. I fall asleep faster and wake up feeling more refreshed. Digestive health — Magnesium Oxide works wonders for keeping my digestive system regular. Stress relief — Magnesium helps me stay more relaxed and less anxious, which is great after a busy or stressful day. Bone and heart health — Magnesium also plays a role in maintaining normal blood pressure and supporting strong bones, which I appreciate as part of my overall wellness. Possible Cons Digestive discomfort— While Magnesium Oxide is great for digestion, it can sometimes cause loose stools if you take too much. However, I’ve found that the Magnesium Glycinate in this formula makes it easier on the stomach, so I’ve never had issues. Results vary — Not everyone may notice immediate or dramatic changes. If you already get enough magnesium from your diet, you might not experience a big difference. Excessive use — As with any supplement, taking too much magnesium can cause side effects, especially for people with kidney issues. Always check with your doctor if you have any concern. Overall Thoughts After using Nutricost Magnesium+ for years, I can confidently say that this combination of Magnesium Oxide and Magnesium Glycinate works wonders for me. It has helped me sleep better, eased muscle soreness, and supported my digestive health. It’s an affordable, high-quality magnesium supplement that I highly recommend if you’re looking to improve your muscle relaxation, sleep, and overall well-being. ... show more

  • My Experience
Size: 240 Count (Pack of 1)
I'm 29 years old turning 30 in a few months, Male, 6'5, 260-290LBS. Bought for multiple reasons. Sleep improvement, leg cramps at night, heart strength, anxiety, no wide variety diet. 1 week of taking the 420mg serving(2 pills) at night before bed. May or may not update review further. 1 hour after taking: - Muscle tension relaxes, my legs aren't restless, and my knees don't noticeably ache as much. - Anxiety calms down. - ADHD brain calms down a bit. Next day: - Much better muscle soreness recovery than when I wasn't taking it. - Back didn't hurt as much. - Heart didn't feel as weak as it has been for a while now, pumping strong. (Occasional heart pains, doctor couldn't find anything) 1 week of use: - Continue to see the same benefits. - No leg cramps at night. - Still no improvement to sleep restfulness but falling asleep has been easier. Possibly sleep apnea which I need to do a sleep study for sometime within the next year. Here comes the obnoxious pilot oxygen mask... yippee... Conclusion: - Will continue to take as I have received beneficial improvements to my life taking it over a short period already. - Pills are a close to uncomfortable to swallow with how large they are but you do what you gotta do. - Would recommend for the first night try just 1 pill and see how it goes before taking 2. - Would recommend doing tests first with your doctor to see what you're missing before taking supplements. Warning: Mixing supplements can lead to a shortage of another vitamin or mineral your body needs. Do research before taking any supplement together to make sure you are not causing harm to your body's functions or chemical productions. ... show more

  • Magnesium eliminated my calf cramps overnight and improved my sleep. Nutricost is a top choice!
Size: 240 Count (Pack of 1)
I struggled with persistent calf cramps that nothing seemed to relieve. I tried increasing my water intake, stretching, going for walks before bed, and various vitamins, but the cramps persisted. It was frustrating to worry about falling asleep only to wake up in pain. After stumbling upon a Reddit post recommending magnesium for better sleep and as a potential calf cramp remedy, I decided to give it a shot, despite my inability to find solid scientific backing. To my surprise, my calf cramps disappeared after just one night of taking magnesium. I haven’t experienced any cramps since, and my sleep quality has significantly improved. I initially tried other brands but ultimately settled on Nutricost due to my positive experience with their other supplements. They offer high-quality products at competitive prices. If you're struggling with calf cramps or poor sleep, I highly recommend giving magnesium a try, especially this Nutricost brand! ... show more

  • Can tell an improvement in sleep and energy
Size: 240 Count (Pack of 1)
I have been using Nutricost Magnesium Glycinate 420mg capsules for a while now, and I must say, they offer excellent value for your money. With a generous number of servings and a substantial amount of magnesium per capsule, these supplements provide a cost-effective solution for boosting energy levels throughout the day. However, I didn't notice a significant improvement in sleep quality, which was a bit disappointing. Let's start with the positive aspects. The Nutricost Magnesium Glycinate capsules truly deliver when it comes to value. With 240 capsules per bottle, this supplement lasts a long time, offering a great bang for your buck. The high potency of 420mg of magnesium per capsule ensures that you're getting an ample dose with each serving, supporting various bodily functions and providing a noticeable boost in energy levels. Speaking of energy, I have experienced a significant improvement in my energy levels throughout the day after incorporating these supplements into my routine. I feel more alert and focused, which has been beneficial for my productivity at work and daily activities. The magnesium glycinate formulation is gentle on the stomach and easily absorbed, allowing for optimal utilization of the nutrient's energizing properties. However, where these capsules fell slightly short for me was in improving my sleep quality. While magnesium is often touted for its potential to promote relaxation and better sleep, I didn't experience a significant impact in this regard. It's worth noting that individual responses to supplements can vary, and other factors such as lifestyle and sleep hygiene practices may play a role as well. However, I was hoping for a more noticeable improvement in my sleep, and that expectation wasn't fully met. Despite the limited impact on sleep, I still believe Nutricost Magnesium Glycinate capsules are a worthwhile investment due to their value and energy-boosting effects. The cost per serving is very reasonable, and the high concentration of magnesium ensures you're getting a potent dose. If your primary goal is to enhance energy levels and support overall well-being, these capsules are an excellent choice. ... show more

  • Magnesium sleep aid

Since this is full strength, I only take half a dose ( 1 capsule ) to help me sleep at night along with 5 MG melatonin. Most nights, I sleep very soundly and a couple hours longer than I used to.
