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

I’m repurchasing this product for the second time, which already says a lot. I’ve tried different magnesium supplements before, but this one stands out because the formula feels very well absorbed – I actually notice the difference in my body. After taking it regularly, I’ve become much calmer, less anxious in the evenings, and I fall asleep faster and wake up feeling properly rested instead of tired. I also really like that it combines several forms of magnesium in one capsule, so I don’t need to buy and mix different products to get a full-spectrum effect. It’s gentle on my stomach, easy to take, and has become a stable part of my nighttime routine. If you’re looking for a magnesium supplement that you can truly feel working – especially for stress and sleep, this one is definitely worth trying.

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
