If you're researching at 1am, we're with you. Type a keyword above to filter, or pick a category from the nav. Every answer below is one we've actually had to give.
Most US orders ship within 1 business day and arrive in 3–7 business days after that. Your order confirmation email shows the exact estimate. International shipping varies by destination.
Yes — we ship to most countries. Available destinations and rates show at checkout once you enter your address. International transit times vary from 7–21 business days depending on customs in your country.
Free standard shipping on US orders over $150. The progress bar in your cart tells you how close you are. Subscribe & Save orders ship free regardless of cart total.
Check with neighbors and household members first — carriers occasionally mark items "delivered" early. If 24 hours pass without it showing up, file a claim with the carrier (their tools work better than ours), then message us and we'll work with you.
That's on us. Send a photo of the damage to support and we'll ship a replacement on the next outbound — no need to return the original. We'd rather send you a fresh tin than make you mail something back.
If your order hasn't shipped yet, message us within 4 hours of placing it and we'll update the address. Once it's shipped we can't intercept it — you'll need to redirect via the carrier's site (USPS Hold for Pickup, UPS My Choice, etc.).
You'll get a tracking link via email the moment your order ships. You can also visit our track-order page or sign in to your account for a direct link.
Pick a delivery cadence at checkout (typically every 30 days). You get a discount on every recurring order, free shipping always, and full control — skip a delivery, swap formulas, or cancel anytime in your account. No phone calls, no fine print, no commitment.
Yes. Sign in, go to your subscriptions, and tap "Skip next delivery" anytime before the charge date. Skipped deliveries push your next ship date out by one cycle — no charge, no commitment.
Yes — swap your subscribed formula at any time from your account. The new formula ships on your existing cadence at the subscriber price. Useful if your needs shift seasonally.
Yes. One click in your account, no "chat with retention," no four-step cancellation form. Whatever's already shipped stays yours. The next cycle just doesn't process.
You're charged on the cadence you picked — usually 30 days from your last shipment. We send a reminder email 3 days before each charge so you can skip if needed.
Sign in and visit your subscriptions. You can update billing info, swap shipping addresses, or change card details — all from the customer portal. No support ticket needed.
Yes — every formula is vegan-friendly, gluten-free, lactose-free, halal, non-GMO, and made without fillers. The strip base is pullulan, a plant-derived polysaccharide. No gelatin, no animal byproducts, no cheap shortcuts.
Pullulan — a clear, plant-based film derived from natural polysaccharides via fermentation. It dissolves quickly on contact with saliva. Pullulan is the same material used in some pharmaceutical capsules and is GRAS-classified by the FDA. More on pullulan →
The exact mg per strip is shown in the safety panel on the Energy product page. Caffeine is sourced from green tea and paired 1:1 with L-Theanine to smooth the response and reduce jitters. Don't exceed one strip per day, and keep your total caffeine intake from all sources under 400mg per day (FDA general guidance for healthy adults).
If you're pregnant, nursing, taking medication, or have a known medical condition, talk to your doctor before using any dietary supplement — including ours. We can't substitute for personalized medical guidance.

Possibly. Curcumin can interact with blood thinners. Andrographis affects blood pressure meds and immunosuppressants. Chromium can affect diabetes medication. If you take prescription medication, talk to your doctor before starting any new supplement — including ours.
Two reasons: (1) Sublingual delivery skips the harsh stomach-acid bath that kills most oral probiotics. (2) The pullulan strip protects the Bifidobacterium lactis through manufacturing and shipping. The tin is shelf-stable in a cool, dry place.
It's 214% of the Daily Value (35mcg). The Tolerable Upper Intake Level for chromium is much higher; 75mcg is well within safe daily range for healthy adults. NIH Office of Dietary Supplements →
Because "Energy Complex 250mg" tells you nothing about how much of each ingredient you're getting. Proprietary blends let brands hide rock-bottom doses behind pretty names. We list every ingredient with its exact dose so you can compare against peer-reviewed research yourself.
Each active ingredient is dosed in the range used in peer-reviewed studies — not the rock-bottom amount that lets us list it on the label, not the megadose that creates side effects. Visit our ingredients page for the research links behind every dose.
Place a strip on your tongue. The pullulan film starts dissolving immediately. Wait about 30 seconds for it to fully dissolve into your saliva. The active ingredients absorb sublingually — bypassing stomach acid and digestion entirely. No water, no chewing, no swallowing required.
No. That's the whole point. Place the strip on your tongue and let it dissolve. No glass, no shaker, no schedule disruption.
Sublingual absorption begins on contact and reaches full effect in about 30 seconds. Compare that to a pill or gummy (30–60 min through your stomach) or a powder shake (similar timing, plus the cleanup). Probiotics work over weeks, not minutes — be consistent for at least 30 days before forming an opinion.
Each formula is dosed for a daily wellness routine. One strip delivers the dose used in the research on these ingredients. Two strips means two doses, which we don't recommend without medical guidance — especially for caffeine, chromium, and probiotic strips.
Don't exceed the recommended dose. Each label specifies a maximum of one strip per 24 hours. For caffeine specifically, keep your total caffeine intake under 400mg/day from all sources (per FDA general guidance for healthy adults).
Technically yes, but the dose isn't designed to be split — half a strip won't deliver half the effect. The active ingredients aren't perfectly evenly distributed across the strip. If you want a smaller dose, take a full strip every other day instead.
Cool, dry place. Avoid direct sunlight and humid bathrooms. Don't open the safety seal until you're ready to use the strips. Once opened, the tin's resealing magnet keeps the rest fresh. No refrigeration required.
30 days from delivery to request a return. The window applies to all orders, including subscriptions. Three outcomes depending on the tin's state: unopened → full refund. Opened and contaminated (foreign matter, mold, off-smell, manufacturing defect) → partial refund. Damaged in transit → refund or replacement, your call. Email us to start the process and see our full refund policy for the specifics.
Yes — but only as a partial refund, and only if the tin is contaminated (foreign matter, mold, off-smell, manufacturing defect). Once the safety seal is broken we can't resell the strips, so a full refund isn't possible — but if something was wrong with the product itself, message us with a photo and we'll issue the partial refund. If the tin is opened just because you didn't like the taste or formula, the strict policy doesn't cover it — but reach out anyway, we'll work with you.
Once we receive the returned tin, refunds process within 3 business days. Your bank then takes 5–10 additional business days to post it back to your card. International refunds can take longer depending on payment method.
Same 30-day window applies, but you cover return shipping. Customs duties and import fees aren't refunded by us — those are paid to your country's government, not Xyne. Reach out for a return label.
Yes — within the 30-day window, on unopened tins. Tell us which formula you'd prefer and we'll send a return label, then ship the replacement. Faster path: keep the original, take the strip quiz to find the right next formula, and order it on Subscribe & Save for the discount.
Yes — the 30-day return policy applies to subscription orders too (full refund unopened, partial if opened and contaminated). If you forgot to skip a delivery, message us within 24 hours of the charge and we can usually catch it before it ships.
Reach out and we'll work with you. We'd rather have honest feedback than a customer who silently regrets the order. The strict policy is unopened tins only for full refund — but if a tin is opened and the issue is the formula or flavor (not contamination), tell us anyway. We can usually find something fair, like swapping you to a different formula on a future order.
