Frequently asked

Your protocol (typically 1–3 compounds) ships every 60 days in a Cura-branded box. Before each cycle you get a review nudge — a 3–5 minute check-in that lets you confirm, tweak, or pause based on how things have been going. The subscription is your main stack; one-off purchases from individual compound pages ship separately in an unbranded box and don't affect the cycle.

At checkout for your first box. After that, 7 days before each scheduled shipment. You'll get an email reminder a few days before every charge with your current protocol and the amount — no surprise invoices. If you pause or cancel before the charge fires, no charge goes through.

Dashboard → Account → Subscription → Pause. Pick how long (up to 6 months). Your protocol and next-box date pick up exactly where you left off when you resume — no re-intake, no loss of history. You can also resume early from the same dashboard page, and shorter-term skip-one-cycle options surface as dashboard tooltips rather than a full pause.

Dashboard → Account → Subscription → Cancel. Two clicks — no retention calls, no multi-step gauntlet. Your account, protocol history, and order history stay accessible so you can still reorder one-offs from compound pages. Restarting later is a single click from the same place.

Most of our compounds need 3–6 weeks to show their full effect, and some take 8–12 weeks before you can really judge them (see each compound page for specifics). 60 days is the first point at which a meaningful review makes sense for most protocols. Shorter cycles mean reviewing effects that haven't landed yet; longer cycles mean getting locked into a stack that isn't working for too long.

Not at launch. The 60-day cadence is currently fixed. Multi-cadence support is on the roadmap once we have data on where users actually want flexibility.

Yes. Any one-off compound from a compound page can be added to your upcoming subscription box if you're within 5 days of its ship date — one unified transaction, one shipment. Outside that window, the one-off ships separately in a plain box and arrives faster.

Your protocol history stays in your dashboard for reference and reorder — we don't wipe it when you cancel. We just stop charging and stop shipping. If you restart later, you can pick up from your last saved stack or launch a fresh review cycle, whichever suits.

Not at launch — the closest thing is pausing, which pushes your next box date out by however long you pause. A true single-box skip (snooze a single cycle) is on the roadmap once we've stabilised multi-box state with our fulfilment partner.

The price of your specific protocol can change if the stack changes — e.g. a review adds a compound, or you swap to a different SKU. Rarely, a compound gets retired from our catalog (new evidence emerges, a supplier issue, a safety update) — in that case we propose a replacement before your next charge and give you the chance to review. We don't silently raise baseline SKU prices. If supplier costs shift materially, you'll get an email before the next charge explaining what's changing and why, with the option to adjust the stack or cancel before you're billed.

UK mainland only at launch. Northern Ireland, Scottish Highlands and Islands, and Channel Islands follow shortly after. EU and US shipping are deliberately post-launch — we want to get UK fulfilment right before expanding.

2–4 working days for UK mainland via our 3PL partner. You'll get a tracking link by email on the day your box dispatches, and the same link appears in your dashboard Orders page.

Browse any of our 12 compound pages (/compounds/[name]) for individual SKUs. Add them to basket, check out, and they'll ship in a minimal unbranded box within a few days. One-offs don't affect your subscription cadence, and you don't need an active subscription to buy them.

Subscription boxes run on a scheduled 60-day cycle with your full protocol and Cura packaging. One-offs move through a faster standard pipeline in a plain box. They use different fulfilment flows at our 3PL — a one-off ordered mid-cycle would sit waiting weeks for the next subscription slot if we batched them, which isn't what users want. If you're within 5 days of a scheduled subscription box, you can bundle them — otherwise they arrive separately.

At checkout, if your subscription box is due within 5 days, you'll see an option to bundle one-offs into the same shipment. One transaction, one box. Outside that window, they ship separately in a plain box.

Email support@mycura.co.uk with your order number and a photo of the issue. Depending on the problem, we'll ship a free replacement immediately or add it to your next subscription box with an apology credit. We don't require you to ship the damaged SKU back — that's wasteful and slow.

Yes for subscription boxes — no separate shipping fee. For one-off orders, shipping is included on orders over £40; below that, a flat £3.50 fee applies.

Yes — you'll get a tracking link by email when your box dispatches, and the same link is visible in your dashboard Orders page. Tracking updates come from our 3PL's carrier network.

No — Cura's protocol recommendations are evidence-based supplement guidance, not clinical advice. They work best alongside a conversation with your GP, pharmacist, or prescriber — particularly if you have a diagnosed condition, take prescription medication, are pregnant, or anything else that warrants professional input. Our protocol pages are designed to be readable by a clinician; sharing yours with your doctor is the easiest way to get a second pair of eyes on what we've suggested.

The Cura Grade is our internal quality rating shown on each SKU card. It combines three things: third-party testing (NSF Certified for Sport, USP Verified, Informed Sport, or equivalent), formulation quality (elemental dose, excipient minimalism, form bioavailability), and manufacturing standards (GMP, batch testing, contamination screening). A+ passes all critical checks; A passes most with minor noted compromises; B or below only gets recommended in specific contexts (e.g. dietary restrictions that narrow the options). Every SKU card has a "Why we picked this" block with the full vetting detail for that product.

We buy the SKUs our system recommends in bulk at trade prices, then sell them to you at a retail markup — that's our margin. What matters: the recommendation pipeline (compound selection, evidence grading, safety rules) runs before any SKU mapping and has no awareness of which brand is cheaper for us. We don't take affiliate commissions from brands, and we never re-rank products because one pays us more. Same retailer model as a high-street supplement store; the difference is that our recommendation logic is margin-blind by design.

We prefer SKUs with third-party verification — NSF Certified for Sport, USP Verified, Informed Sport, or equivalent. When we recommend a SKU, the product card on that compound page explains which certifications it has (or doesn't) and where the testing data comes from. Where a compound category genuinely has no third-party-tested option at a reasonable price, we say so rather than pretend otherwise.

The intake captures your medication list, and the safety filter checks each compound against known interactions. For higher-risk medications (anticoagulants, lithium, immunosuppressants, certain adaptogens + SSRIs), the filter either excludes the compound or flags a specific caveat. If you're on multiple medications or anything complex, review the full stack with your prescriber before starting — your protocol page is designed to be clinician-readable.

Most supplements lack strong safety data in pregnancy and breastfeeding, so the intake treats it as a reason to exclude most of our compounds by default. We'll only recommend supplements with well-established pregnancy safety profiles — typically a short list. Everything else gets flagged for a conversation with your midwife or doctor.

Our protocols are designed for adults. Under-18s can have legitimate supplement needs (vitamin D deficiency, iron-deficient teenagers, etc.), but dosing, formulation, and safety profiles differ meaningfully from adult recommendations — those need a paediatrician or GP, not a protocol builder.

Yes — allergies captured at intake are automatically excluded from your recommendations. SKU selection also respects excipient-level allergens where known (e.g. shellfish-derived sourcing, fish-oil origin for anyone with fish allergies, nightshade-derived ingredients). If your allergy isn't in our standard list, flag it in the intake free-text and we'll add it to the filter.

Dashboard → Profile → Edit to update it. New information triggers a safety re-check — if a current compound becomes unsafe given the new condition, we'll flag it and propose an alternative on your next review cycle, or immediately via the "Update my protocol" button if you prefer not to wait.

No — we're not a diagnostic service. If you describe symptoms at intake, our system can sometimes suggest which compounds tend to help similar patterns, but it can't tell you what's actually causing those symptoms. Persistent symptoms (fatigue, brain fog, anxiety, GI issues, sleep disruption, hormonal changes) often have underlying causes that need a GP's workup — blood tests, a thorough history, sometimes a specialist referral. Supplements are a layer on top, not a substitute for working out what's actually going on.

No — don't stop or change prescribed medication on the back of a Cura recommendation. Medication changes belong with your prescriber. Our protocols are designed to work alongside whatever medications you're on (the safety filter accounts for them), not as a replacement. If you want to reduce or stop a medication, that conversation is with the clinician who prescribed it.

Deterministic rules in code, not guesswork. The safety filter runs coded interaction rules against your profile. For some combinations — omega-3 with warfarin, for example — the interaction is severe enough that we'll exclude the compound from your protocol entirely. Lithium requires direct medical supervision for any supplement. For others like pregnancy or kidney history, we'll ask a clarifying question before recommending. The rest get a flagged note in your protocol so you can discuss with your prescriber. Every rule traces to documented interaction evidence, and the decision trace shows which rules fired for your specific stack.

Share your protocol page — it lists each compound with dose, timing, rationale, and evidence citations. Your doctor can flag anything that doesn't fit your full medical picture. The page is designed to be clinician-readable — one compound per block, no marketing language.

Stop the compound immediately if severe — any allergic reaction, persistent GI distress, or unusual symptoms. For mild or short-lived effects, the dashboard has a "Report side effect" action that flags the compound on your next review so we can adjust the dose, swap the form, or remove it. Anything more than transient warrants a GP conversation.

Google or email + password. Sign-up is required before starting your intake — we save your profile, protocol, and order history so you can return, review, and adjust over time. If you forget your password, the sign-in page has a reset link.

In a secure, UK/EU-region Postgres database (Supabase), encrypted at rest. Access is locked to your account at the row level — no one can query your data without your auth token. We don't sell, share, or market against your health data. The full privacy policy is linked in the footer.

Yes. Dashboard → Account → Delete account. All personally identifying data is removed within 30 days, in line with your UK GDPR rights. Anonymous aggregate data (e.g. "X% of users report improved sleep on magnesium") may be retained in aggregate form only — no individual-level data lingers.

Only you and the Cura systems that build it. We don't share protocols with third parties, advertisers, or other users. If you email support or the founder, your messages may be read by a Cura team member for handling. Everything else stays in your account.

Your account, protocol history, and order history stay accessible as long as you have an account. Cancelling only stops the subscription and billing. If you want your data removed entirely, delete the account — that's a separate step so you don't lose access to reorder or restart later.

Dashboard → Profile → Edit. You can update goals, medications, conditions, allergies, and preferences (vegan, budget, form preferences) at any time. Significant changes (new medication, new condition, new allergy) trigger a safety re-check and offer a review cycle to rebuild your stack against the updated profile.
