BIOptimizers Magnesium Breakthrough Supplement 4.0 | 7 Forms of Mg: Glycinate, Malate, Citrate, and More | Natural Support for Sleep and Cognitive Function | Calming Vitamins Complex | 30 Capsules

Promptly delivered, excellent quality, seal intact, long date and the best magnesium supplement.

A biological dentist recommended this product because it provides seven types of magnesium and so if my body didn't take up one form, another type was available. My quality of sleep has improved and elimination in the morning feels comfortable.

Good product

I used to spray magnesium on my feet and legs to stop cramps but it barely worked. Bought these and found they are good for cramps, around 98% for me, also the early morning trip to the bathroom has been extremely welcome for my constipation, but did nothing for my sleep. However, the expense of £58 a month is far more than I can afford, after realising that I would need two bottles per month, so will be looking out for some other magnesium that will hopefully work.

very efficiente ! Perfect

Love that these combine a range of different types of magnesium. Saves taking many tablets. Good reliable brand, recommended by a trusted doctor.

Doesn’t work for me sadly. It hasn’t helped my sleep or cramps. Considering the cost I won’t be buying again.

Really good magnesium and so much better sleeping

حلو بس غالي ناسبني اكل حبه قبل النوم بساعه يحسن جودة النوم

Items were well packed & arrived on time! Expiry date of items is in June 2026 which is alrite but would be better with a later expiry date. Price of item would be more attractive if can be made lower. Overall, I would give a 4-star rating!

I have tried so many MG brands, but this was the best for me Im falling a sleep like a baby

I’ve been using this magnesium for a few weeks now and I’m really impressed with the results. It helps me relax in the evening and noticeably improves my sleep quality — I fall asleep faster and wake up feeling more rested. I also feel less muscle tension and stress during the day. The capsules are easy to swallow and don’t cause any stomach discomfort, which is a big plus for me. Overall, this is a high-quality supplement that actually works. I will definitely continue using it and repurchase!
