1. Why ARC?
Most sleep supplements lean on melatonin, or bury small amounts of a dozen ingredients in a blend you can’t read. We wanted the opposite: a handful of well chosen ingredients, in forms your body can use, with every dose printed on the label.
ARC is the result. Five ingredients, two capsules, every milligram printed on the label. It’s built for the nights when your body is tired but your mind won’t switch off.
2. What’s in two capsules
Ashwagandha root extract 300 mg (7% withanolides) · Magnesium 148 mg from magnesium bisglycinate · L-theanine 200 mg · Apigenin 50 mg · Vitamin B6 2.5 mg as P5P.
No melatonin. Just five research backed ingredients
3. Quality and testing
ARC is made in the EU by a GMP-certified manufacturer. It’s also certified by the NZVT, the Dutch anti-doping programme, so athletes who are tested can take it with confidence.

4. How to take ARC
Two capsules with a glass of water, about 30 minutes before bed. Take it every night: some ingredients work within days, others build over a few weeks, so give it a full 30 days.
5. Our 90-day guarantee
We think you’ll feel the difference, but everyone’s sleep is personal. If ARC isn’t right for you, get in touch within 90 days of your first order and we’ll refund you in full.
6. Flexible subscriptions
ARC works best as a nightly routine, and a subscription makes that easy. Choose monthly or every 3 months, and skip, pause or cancel any time from your account. No calls, no emails, no hoops.
7. Shipping
Order before 22:00 on a weekday and we deliver the next day in the Netherlands and Belgium. Elsewhere in the EU, delivery takes 3 to 5 working days. Subscriptions always ship free, and you’ll get a tracking link as soon as your order leaves us.
8. Claims and benefits
Magnesium contributes to normal functioning of the nervous system, normal psychological function, normal muscle function and the reduction of tiredness and fatigue. Vitamin B6 contributes to normal psychological function and the reduction of tiredness and fatigue. *Approved EU health claims.

ARC is great! Finishing my fourth bag soon and definitely ordering it again. I fall asleep way more easy and wake up more recovered ever since starting! Loveloveloveee it
Geweldig, sinds ik het gebruik, slaap ik dieper en wordt uitgerust wakker Ik beveel het iedereen aan
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!
Sinds ik ARC heb genomen, heb ik een positieve verandering in mijn slaap opgemerkt en ik voel echt het verschil of ik het wel of niet neem. Ik zal zeker opnieuw bestellen!
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.
Ik beveel al deze ingrediënten aan mijn klanten aan. Dit is een goede formule.
Ik gebruik dit nu al een paar weken en hoewel ik niet veel slaapproblemen heb, word ik wel rustiger en uitgeruster wakker. Een aanrader!
Great product, I feel a lot calmer the last couple of weeks since taking ARC! Thank you!!
