magnesium
Verified Purchase
It can be eaten alone because it contains beta-carotene. The tablets are slightly larger, which is suitable for adults. The portion size is sufficient, the packaging is simple, and the quality and ingredients are good. I recommend it to friends who need magnesium.

good for relax
Verified Purchase
I love the quality ingredient that time release for 8 hours. I take 2 tablets at bedtime. This malate magnesium helps sleep, relaxation, muscle pain, and joint pain. The package is cost effective yet benefit for 2 months. Magnesium is one of the most important minerals that help hormone cortisol. The taste is fair amd easy to swollow.

Great
Verified Purchase
I like how this magnesium is timed release. The product is expensive but I think it is worth it to have the magnesium slowly release throughout the day. Jigsaw health uses quality MagSRT. The size of the tablets is small enough that I can swallow 2 at a time, which is the recommended dose.

Best Magnesium Supplement I’ve Tried!
Verified Purchase
I’ve been taking this magnesium supplement and it’s made a big difference. It helps me feel more relaxed, improves my sleep, and reduces muscle cramps. I really like the sustained-release formula—it’s easy on the stomach and provides steady support throughout the day. No crashes or digestive issues like with other magnesium supplements. Great quality and well worth it. Highly recommend!

Sustained magnesium and active B for sleep and mental stability
Verified Purchase
For water-soluble vitamins and minerals that are difficult to absorb if taken in large quantities at once, sustained-release forms are recommended. Many calcium and magnesium products, in particular, neutralize stomach acid, so capsules should be avoided with meals. Sustained-release magnesium supplements, which are absorbed slowly and do not rapidly increase body concentrations, are convenient because they do not require as much attention to timing. While various companies offer magnesium supplements for various purposes, this product, based on its other ingredients, appears to be primarily intended to enhance relaxation, such as stress relief and improved sleep quality. B6, B12, and folic acid support the synthesis of the neurotransmitters serotonin and GABA, potentially promoting mental stability and calming the mind. It's great that all of these are in highly absorbable, activated forms. Magnesium malate, which reduces fatigue, is perfect. To improve sleep quality, taking several doses before bedtime rather than taking a single dose just before bed is more effective, allowing for sufficient serotonin secretion during the day and melatonin production at night. Taking it once in the afternoon and twice in the evening (4-5 hours before bedtime) so that the ingredients are more abundant at night seems to work best for me, and it helps me sleep more deeply and soundly until morning. After trying another company's glycine magnesium, I switched back to this product and was once again impressed with its effectiveness. I trust it and will continue to use it.
