Looking for efficient magnesium spray for muscle relaxation and sleep? With essential oils?

5-10 sprays applied directly on the muscle can remove those annoying cramps and give you back your sleep. It’s recommended to use after hot shower, because the pores are open and the magnesium is absorbed more efficiently.

By the way, the magnesium spray can be applied to any part of the body, not just the muscles.

Except for the eyes, of course.


My personal observations


  • It works (at least for me). Because of the review I ordered the spray. A few sprays + massage did away with the muscle soreness after a heavy squat. As a matter of fact, the muscle soreness was mild, no telling how it will help you if you have stronger. Keep in mind this is not a cure and you can’t expect miracles.
  • Travel-friendly. Fits in my backpack or suitcase. Way more convenient than capsules or tablets.
  • Smells good;
  • Vegan and vegetarian friendly;
  • Free from GMO, allergens etc.;



  • The spray is a bit sticky and leaves stains. Better wait for it to dry before going to bed or putting on clothes. Not a deal breaker, but still…
  • There have been complaints that the essential oils in the spray irritate the skin;
  • Some find the spray a bit on the expensive side;

Suitable for vegans and vegetarians. 100% natural sources. Suitable for use during pregnancy. Free from parabens, allergens, palm oil, GMOs and synthetics. Travel-friendly packaging. Chosen by Amazon as “best magnesium sleep spray”.

How much magnesium do I need per day?

How much magnesium day

According to the NHS – 300 mg./day for men (19-64) and 270 mg./day for women ¹.

During pregnancy the magnesium demand increases ².

  • For pregnant women between 19 and 50 – 360 mg./day.
  • For breastfeeding women between 18 and under – 360 mg./day.
  • For breastfeeding women between 19 and 50 – around 310-320 mg./day.

If you are hitting the gym regularly (or practise another sport) you could increase the daily dosage to 500-800 mg/daily. Some suggest even higher doses, but more research is needed on that.

OK, which is the best time of the day to take magnesium supplement?

As with most supplements, the most important thing is to take regularly.

There are assumptions about the best time to take according to the form of magnesium (oxide, citrate, etc.), but there is no 100% evidence. The most convenient way for most people is a magnesium tablet with breakfast.

By the way, if magnesium irritates your stomach, be sure to take with water and food.

Speaking of…

Almost all contain 100% of the daily dose in 1-2 tablets/capsules. Keep in mind that the body’s magnesium needs increase with pregnancy, increased physical activity (sports, working out etc.) or certain medical conditions.
