Calm body148 mg magnesium (39% RI), from magnesium bisglycinate
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.
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
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.

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.
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.
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.
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.
