Great Quality Magnesium — Gentle, Effective, and Clean Formula
I’ve been using this NOW Foods Magnesium 400mg supplement regularly, and it’s one I keep on hand. It’s helped noticeably with muscle tension, sleep quality, and stress levels, especially during busy or high-stress weeks. I also take it to support nervous system function and occasional leg cramps, and it’s made a clear difference.What I really like is that it’s a blend of magnesium forms, not just one type. This helps with better absorption and effectiveness, and it feels much gentler on my stomach than other magnesium supplements I’ve tried in the past.The capsules are veggie-based, which is a big plus if you’re avoiding gelatin, and the ingredient list is clean, no unnecessary fillers, artificial colors, or preservatives. The 180-count bottle is a great value and lasts a long time, even if you’re taking two capsules a day.If you’re looking for a high-quality, plant-based magnesium that’s easy on digestion and actually works, I’d definitely recommend this one.

easy to swallow capsules, works well enough to help me drift off to sleep
Pretty good. I use this to help me sleep. I have a preferred brand, but the price doubled recently and I dont want to reward that. But that one is still the best for me, so I may have to shell out the money anyway. But in mean time I will use this up. As with any magnesium, unless it expressly states what the elemental magnesium (non chelated) amount is, you can figure that it has about 1/10 of what is listed.While some magnesium chelates absorb better than others, and some have different functions than others, it really comes down to what works for you. Try different styles, brands. If you are new to mag supplementation, start low and slow. I use it at night as it makes me a sleepy. Some more than others.I’d consider this brand again if I cant find (or afford) my preferred brand.
