Common questions
-
How long before I notice a difference?
It depends on the ingredient. Apigenin and L-theanine work quickly and most people notice a difference within the first few days. Magnesium and P5P build over 1–2 weeks. Ashwagandha takes 3–4 weeks to fully establish. Give ARC one complete 30-day cycle.
-
Why no melatonin?
Melatonin tells your body what time it is — it doesn't improve how you sleep. Nightly supplementation can dampen your own production over time. ARC works differently.
-
Can I take ARC if I'm already on medication?
Always speak to your doctor or pharmacist before taking ARC alongside prescription medication — particularly thyroid medications, immunosuppressants, or sedatives.
-
Can I take ARC during pregnancy or breastfeeding?
We don't recommend ARC during pregnancy or breastfeeding as ashwagandha has limited safety data in pregnancy. Please speak to your doctor or pharmacist before use.
-
Are the capsules suitable for vegans?
Yes. HPMC capsule shell, rice flour as a flow agent. That's the entire inactive ingredient list.
