Customer Reviews

Overall rating: 5 / 5 from 8 reviews.

After trying this supplement blend, I've noticed a real improvement in my overall wellbeing and sleep. I'm sleeping more consistently through the night and feel that my sleep is deeper and more restful. Having been looking for a supplement to support me through perimenopause, I'm so glad to have found ARC. It's been a lovely addition to my daily routine!

ARC | Night Time Food Supplement with Magnesium and B6

I'm an amateur ultra-endurance trail runner, which means I spend a lot of hours training on top of having a full-time job in charge of the communication for an organisation in the EU Bubble and being a single dad to a 7-year-old daughter. As you can imagine, there are a lot of stressors in my day-to-day life, and for quite a while they've affected my cortisol levels, often causing me to wake up in the middle of the night and struggle to get back to sleep. ARC got in touch after seeing some of the inspirational content I share on Instagram (@binaural_trails) and offered me the chance to try their product. I've been taking one dose every night for the past three weeks. With Val d'Aran by UTMB coming up in two weeks and Gauja by UTMB in August, I was really keen to do whatever I could to improve my sleep. Since I started taking ARC, I've been sleeping right through the night and feeling much more relaxed overall. I'll keep sharing updates on how I'm feeling, but so far I'm really happy with the results. So if you're an endurance athlete like me and you're trying to balance training with work, family, friends, and everything else life throws at you, this product could definitely be worth a try.
