It doesn't taste good, but it's essential.
Verified Purchase
Because magnesium has a unique unpleasant taste, I mix it into spiced drinks like café au lait or milk tea with cinnamon. I'm not sure if this is the correct way to drink it, but I continue to take it for the sake of my sleep quality, gut health, body aches, and mental well-being. It is effective.

For a magnesium boost
Verified Purchase
If you're taking a variety of minerals such as multiminerals, natural salt, trace minerals, and colloidal minerals, and you just want to boost your magnesium intake, take this single magnesium. It'll take some experimenting at first to find the optimal daily amount of magnesium for you. Magnesium is the gold standard for superficially calming nerves, but if that alone doesn't alleviate your nervous symptoms, consider adding boron, silica, citicoline, tyrosine, PS, and lithium. DHA is also important.

It's an excellent mineral, especially when it's in drop form, easy to dose, and suitable for both children and adults. It's all about the dosage.

A magnesium complex for nervous system and muscle support. Helps reduce fatigue and improve overall well-being. The capsules are easily digestible, and the formula is pure, without unnecessary additives.

The best magnesium in my opinion
Verified Purchase
I like this supplement better than the capsules. The only downside is probably the taste—it's sour, bitter, and salty, which might not be everyone's cup of tea. But I've gotten used to it and find that this magnesium is absorbed faster. And it really does help you calm down and relax before bed. I definitely recommend it!

The taste is like concentrated mineral water; it's bitter and astringent, making it a bit difficult to drink, but still manageable. Diluting it with more water helps a lot, making it much easier to drink. As for the effectiveness, it's not yet clear because I've only just started taking it. It hasn't significantly improved my sleep; I usually don't sleep well, and I haven't seen any other changes yet.

Mega-Mag by Trace is a real “liquid energy” for the body. ⚡ After the first week, I noticed that fatigue goes away faster, sleep becomes deeper, and muscles recover without unpleasant cramps. It is convenient that this is liquid magnesium with minerals - you can add it to water, since it has a specific taste, but it is immediately absorbed. Pure composition, noticeable effect - now this is my must-have for every day.
