Brain fog can have many causes, and Ārepa isn't a treatment or cure for any medical condition. What our Brain Capsules for Cognitive Support are designed to do is support your brain's daily performance — focus, mental stamina, and clarity — using a neuroscientist-formulated blend of Neuroberry® Blackcurrant, L-theanine, and Pine Bark Extract (Enzogenol®). Many of our customers find that consistent daily use helps them feel sharper and more on. As with any supplement, results vary depending on your individual physiology, sleep, diet, and lifestyle. If you have ongoing concerns about cognitive function, we recommend speaking with your healthcare professional. Always read the label and use as directed. Vitamins and mineral supplements should not replace a balanced diet.

Our Brain Capsules contain naturally derived ingredients. Ārepa is not known to interact with HRT, however because our ingredients are bioactive, we always recommend checking with your GP or healthcare professional before combining any supplement with prescription or hormone-based medications. They'll be best placed to advise based on your personal health profile. Always read the label and use only as directed.

Yes, absolutely. Ārepa was designed for anyone who wants to support their brain health, HRT or no HRT. Our Cognitive Support Capsules contain research-backed ingredients to support focus, mood, and mental stamina as part of your daily routine. Our Sleep Support Capsules are designed to help support a calmer wind-down and more restful sleep. Both products are for anyone looking to support their brain from the inside out. Always read the label and use as directed. Vitamins and minerals are supplementary to and not a replacement for a balanced diet.

Everyone's different, and how quickly you notice a difference depends on factors like your existing physiology, sleep habits, diet, and exercise. For the Cognitive Capsules, some people report feeling a difference within the first use; for others it builds over time with consistent daily use. For the Sleep Capsules, many people notice calmer evenings within 1–2 weeks of nightly use, with the best results typically seen after 4 weeks of consistent use. Clinical data from our ingredients suggests meaningful sleep-quality improvements stacking up over 3–4 weeks. We recommend giving your brain a full 30-night cycle before drawing conclusions — neurons love routine.

No. Ārepa Brain Capsules are 100% natural and completely caffeine-free. Our formula contains no stimulants. The Cognitive Capsules use L-theanine — an amino acid naturally found in green tea — which is associated with supporting calm, focused mental states without the jitteriness of caffeine. The Sleep Capsules are specifically formulated to support a natural wind-down and restful night. Always read the label and use as directed.

Our Sleep Capsules are melatonin-free and formulated with ingredients shown in clinical research to support sleep quality without next-day sedation. Rather than overriding your body's sleep systems (as melatonin can for some people), our blend of L-theanine, Magnesium Bisglycinate, and Affron® Saffron is designed to support your body's natural sleep rhythms — helping you wind down at night and wake feeling clear-headed. Think of them as a sleep sidekick, not a knockout punch. Individual responses may vary. Always read the label and use only as directed.

It depends on what your brain needs most right now:

• If daytime focus, mental clarity, and stamina are your priority, start with the Brain Capsules for Cognitive Support. Take 2 capsules with water, about 1 hour before you need to perform.
• If winding down at night and getting more restful sleep is your goal, start with the Brain Capsules for Sleep Support. Take 2 capsules 30–60 minutes before bed as part of your evening wind-down routine.
• Many people use both — the Sleep Capsules at night and the Cognitive Capsules during the day — as a complementary brain support routine.

You don't need it — the Brain Capsules work as standalone products. That said, the Brain × Gut Powder is formulated to support the gut-brain connection, and many of our customers pair it with the capsules as part of a broader brain health routine. The right combination really depends on your personal health goals. If you're new to Ārepa, we'd suggest starting with the capsule that addresses your most pressing need, then building from there. Always read the label and use as directed. Vitamins and minerals are supplementary to and not a replacement for a balanced diet.

Ārepa contains only natural, plant-based ingredients, and our formula is designed to be food-safe. However, because our ingredients are bioactive, we strongly recommend consulting your GP or healthcare professional before taking Ārepa alongside any prescription medication, including antidepressants. They can advise based on your specific medications and health history. Always read the label and use only as directed. If you are pregnant, breastfeeding, or taking prescription medication, please seek advice from a healthcare professional before use.

Generally yes — many of our customers take Ārepa alongside other common supplements. A couple of things worth noting:

• The Sleep Capsules already contain 200mg of elemental magnesium per serve (as Magnesium Bisglycinate). If you're also taking a separate magnesium supplement, be mindful of your total daily magnesium intake and check with your healthcare professional if unsure.
• Fish oil and creatine are not known to interact with Ārepa's ingredients.
• Our Brain × Energy Powder also contains 3g of creatine monohydrate per serve, so factor that in if you're already supplementing creatine separately.

As always, if you have specific health concerns or are taking multiple supplements, we recommend checking in with your GP or healthcare professional. Always read the label and use as directed..
