A Premium Magnesium Powder From A Brand I Actually Trust
Thorne has a strong reputation in the supplement world, and this Magnesium Citrate powder is a good example of why. Magnesium is one of those basic minerals that does more than people realize. It supports normal muscle and nerve function, helps with energy production, contributes to bone health, and plays a role in cardiovascular function. The NIH notes that magnesium is involved in hundreds of enzyme systems in the body, including processes tied to muscle and nerve function, blood glucose control, blood pressure regulation, and bone development. (Office of Dietary Supplements)
Magnesium citrate in particular is a form many people use because it is generally well absorbed and can also help with occasional constipation. That is both a benefit and something to respect. If you take too much, it can move from “helpful” to “where is the nearest bathroom” fairly quickly. I would start modestly and see how your body responds.
The citrus berry flavor is pleasant enough for a mineral powder. It is not candy, and it does not need to be. It mixes reasonably well and is easy to work into a nightly routine or use when you feel like your muscles are tight, your diet has been less than ideal, or you simply want magnesium without swallowing another capsule.
The biggest selling point for me is the brand. Thorne is not some mystery-label supplement company with a pretty bottle and a warehouse address nobody wants to talk about. Thorne says its facility is NSF certified, it manufactures more than 40 NSF Certified for Sport products, and it is used by professional and national sports organizations. (Thorne) Their Magnesium Citrate product page also states that the product is third-party tested and certified to verify what is in the package. (Thorne)
That matters with supplements. You are not just buying magnesium. You are buying confidence that the dosage, purity, and manufacturing standards are being taken seriously. Thorne usually costs more than bargain brands, but with supplements, cheap is not always the victory it looks like on the front end.
Overall, this is a high-quality magnesium option from a brand with real credibility. I like it for muscle support, general wellness, bone and heart-health support, and occasional regularity. Just treat it like a supplement, not a snack, especially if you are sensitive to magnesium or already taking other products that contain it.

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.
