Taste is good, reliable manufacturer
Thorne is a reputable brand that has come out with a magnesium citrate and has been certified by a third-party. I sometimes wonder about supplements online, but having a third-party certify the product gives me more peace of mind. It comes in a double protected container for further peace of mind. This magnesium citrate comes in a powder form and mixes fairly easily with cold water. There is bicarbonate in the product, so it has a slight bubbly texture. This really tastes like citrus berry and is sweetened with monk fruit extract. I like that it has no artificial sweeteners in it. Magnesium has been known to support muscle heart bone and the urinary tract. It can also help with constipation. My husband is a nurse and he says that they regularly administer this in the hospital when a patient has trouble with constipation. The recommended dosage is one scoop to 6 to 8 ounces of water. There are about 60 doses in the container. If taken once a day, this will last for two months. This is a good alternative to other magnesium supplements. It is a form that is usually well absorbed by the body. Given the reputation of the manufacturer, the ease of use, the benefits, and the ease of absorption, I can recommend this product if you are looking to increase magnesium in your diet.

Certified quality magnesium citrate
If you like powdered supplements and planning to take magnesium citrate, then this one if for you. I take it towards the end of the day, and in addition to the many benefits of magnesium, it actually helps me relax and sleep better, although those are not the main benefits of citrate. I guess we all react differently to supplements. My favorite setup is when I take it in the evening and sip on it during a sauna session. In all cases, I target end of day. The taste is very good and it mixes easily with water. Also, Thorne is a brand I trust and it's certified by various bodies. It's worth the premium but it's better to catch a deal on amazon or add it to subscribe and save for a discount if you're planning to use it long term.

Best magnesium from the best supplement brand.
Thorne can do no wrong in my book. They just can’t. I take magnesium every night. Usually magnesium glycinate. However, I read that that can start to cause night sweats over overtime. So moving decent was kind of a trial to see if that stopped the issue. It did immediately. The bonus of the powder though is that I can have it in a little bit of cherry juice or a mocktail before I go to bed. The flavor is great, and I haven’t noticed any grittiness whatsoever. That’s sad, I drink a lot of protein drinks so it’s entirely possible. I’m used to grittiness. Since starting to take this, I’ve been sleeping just as well as I have with the magnesium glycinate. Perhaps even a little bit better because this is higher quality and I’m not getting the night sweats.

Simple Magnesium Powder That Is Easy Enough to Take
I just started taking this Magnesium Citrate powder, so it is too early to know if it will help with things like muscle support, heart health, bone health. Magnesium is an important mineral for the body and it plays a role in muscle function, nerve signaling, and overall balance, so I like the idea of adding it to my routine. The citrus berry flavor is not too horrible, which is a pleasant surprise because some magnesium powders can taste pretty rough. This one is easy enough to drink without feeling like you have to force it down. I also like that it is third party certified and comes with a full sixty servings. I will need more time to see if it makes a noticeable difference, but so far the experience has been simple and the taste is manageable.

2 months supply, tasty berry bubblegum flavor, no morning cramps.
I've been taking Magnesium supplements for a long time, usually in capsule form. Starting from about age 45 I kept getting these awful morning calf cramps. Especially stretching, or on cold morning. The sudden agony was unexpected and concerning. Magnesium is the answer and this water-soluble magnesium from Thorne is no exception. For this particular problem, calf cramps. The results are noticable within a couple of days. If I stop taking magnesium for 3-5 days the cramps come back. Thorne powder has a berry flavor that is very similar to bubble gum. It dissolves easily without leaving any lumps. Is great to help you take your other supplements. I've been taking this for about 3 weeks with no cramps. Price is a little higher than capsules typically are. This works for me and the tub should last two-months if you follow the directions.
