Started taking this before marathon training kicked in and my legs have been far less prone to cramping. Happy with it.

Been taking this for about six weeks now and the difference in my sleep quality is noticeable. I take two capsules about an hour before bed and I'm falling asleep faster and waking up less groggy. Added it to my evening routine after dropping caffeine after noon — seems like the two changes together have really helped.

Does exactly what it says. Take it every night before bed, sleep quality has improved noticeably. Would buy again.

Tried a few cheaper magnesium products before landing on this one. The difference is real — less muscle cramping after long runs and I feel noticeably calmer in the evenings. Worth the extra spend compared to bog-standard magnesium oxide tablets.

Noticed genuine improvements in recovery after gym sessions — legs feel less tight the morning after leg day. My only gripe is the capsule size, they're quite large and I occasionally struggle to swallow them. Would be great if they offered a smaller capsule or powder option. Would still recommend though.

I stack this with vitamin D and zinc in the evenings. Sleep is deeper, anxiety feels more manageable day-to-day, and I haven't had a tension headache in weeks. I was sceptical about whether having multiple forms of magnesium in one capsule actually mattered — I think it does, though it's hard to isolate exactly why I feel better.
