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!

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.

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.

I've tried several magnesium supplements before, and this one from BiOptimizers has been one of the best. It's well-absorbed, doesn't cause me any discomfort, and I really notice the difference in my muscle relaxation and sleep quality. Plus, the formula is high-quality and feels more effective than others I've taken. I recommend it if you're looking for a magnesium supplement that actually works.
