Easy Way to Add Magnesium Support
Magnesium is one of those supplements many people find helpful as part of their wellness routine. The powder format makes it easy to adjust serving sizes and mix into drinks.
One thing I liked was the citrus berry flavor, which made it more pleasant than many unflavored supplements. Overall, a convenient magnesium option from a well-known brand

Great Taste and Mixes in Water Well
I’ve been using this magnesium citrate powder for a little while now, and overall it’s been a positive experience. One of the standout aspects is how well it mixes. It dissolves easily in water with minimal residue, which makes it much more convenient compared to some other powdered supplements I’ve tried. The citrus berry flavor is also quite good: light, slightly sweet, and easy to drink without being overpowering. The powder format makes it simple to adjust how you take it (more or less water, etc.), and I didn’t notice any strong aftertaste. From a general usability standpoint, this checks the boxes I look for in a supplement: good taste, easy mixing, and consistent quality. Thorne also has a strong reputation, and this product feels in line with that in terms of formulation and overall experience. As with any supplement, individual experiences can vary, but from a taste, mixability, and convenience perspective, this has worked well for me. Overall, this is a solid option if you’re looking for a magnesium citrate powder that’s easy to take on a regular basis.

Great Magnesium Blend That Actually Works
Size: 100 Count (Pack of 1), Size: 100 Count (Pack of 1)
I’ve been taking Life Extension Magnesium Caps (500 mg) for a few weeks now, and I can really feel the difference. It’s a blend of magnesium oxide, citrate, and succinate, and I’ve noticed improved sleep quality and fewer muscle cramps at night. The capsules are easy to swallow and don’t upset my stomach, which has been an issue with other magnesium supplements I’ve tried. Plus, I like that they’re vegetarian-friendly and come in a 100-count bottle, which lasts a good while.
What I appreciate most is how balanced this formula feels. I take it mainly for sleep, muscle support, and overall well-being, and I genuinely notice I feel more relaxed, especially in the evenings. For the price and quality, it’s a great value. I’ll definitely keep this one in my daily routine.

This Magnesium Is Worth It!
Size: 100 Count (Pack of 1)
Life Extension is a quality company, and this Magnesium is very good.
I have been taking it for maybe a year, and it helps me steer clear of debilitating nightly leg cramps, and also helps my digestion from getting sluggish.
I don't really see any reason to change brands, because I trust Life Extension to deliver a high-quality product, so I'm just gonna stick with it. Recommended!

Truly a miracle worker!!
Size: 100 Count (Pack of 1)
I used to wake up every day and struggle to go to the bathroom. After taking these for just one week straight, I have already started to become normal having at least one bowel movement a day. This is my third bottle. I take them everyday and don't think I will stop.
