More about it

Magnesium runs more than three hundred reactions in the body, from muscle and nerve function to energy production, blood sugar control and the wind-down chemistry that lets you actually relax. It is also one of the most common shortfalls in a modern diet, and stress, hard training and caffeine drain it faster still.

Form is what separates this from the magnesium on a supermarket shelf. Bisglycinate binds the mineral to the amino acid glycine, which makes it both highly absorbable and easy on digestion, with none of the loose-stool effect that cheap oxide is infamous for. The glycine brings a calming benefit of its own on top.

Thorne's version is clean and precisely dosed at 200mg of elemental magnesium per serving, made to the standard that has kept the brand in clinical practice for decades. It is the kind of unglamorous staple you only notice once you stop running short of it.

It works morning or night: for muscle and energy through the day, or for calm and deeper sleep in the evening. A genuine everyday base, and a natural partner to omega-3 and vitamin D.

Quiet, steady improvement in sleep. Not a miracle, just does the job consistently.

Finally sleeping through the night

6 months ago

Been taking this for about six weeks now, always about an hour before bed. The difference in how quickly I fall asleep has been noticeable — I used to lie there for ages with my mind racing. Nothing dramatic, just a quiet shift. Worth every penny for me.

PM

Good quality but capsules are large

6 months ago

The product itself seems solid — I've noticed less muscle cramping during my training block and sleep is better. My only gripe is that the capsules are quite large and I struggle to swallow them. Would prefer a smaller size option. Still reordering though.

JW

Switched from citrate form

6 months ago

Used to take magnesium citrate but it was wreaking havoc on my stomach. This form is so much gentler — zero digestive issues and I genuinely feel like my sleep quality has improved. Takes a couple of weeks to notice anything but stick with it.

MH

Works well, price is a stretch

6 months ago

I can feel the benefit — noticeably calmer in the evenings and my sleep has improved. The quality feels high and I trust the brand. That said, £63 for a supplement is a lot and I find myself calculating how many doses are left. It's good, but I do wince at reorder time.

Does exactly what it says. Sleep is deeper and I wake up less groggy. Stacking it with zinc and vitamin D — fits in well.
