Supplement Check. Compare an amount of a vitamin or mineral with the adult RDA and upper limit. Use for "is 5000 IU of vitamin D too much?", "is 500 mg of magnesium glycinate safe?", "is 10 mg of melatonin a lot?" or "is 300 mg of caffeine too much?". Handles IU, mcg, mg and g, including IU for vitamins A, D and E and DFE for folate. For vitamins and minerals, status is above, at, within or no_upper_limit; when the name is a compound (magnesium glycinate, ferrous sulfate, zinc gluconate) the `compound` field also gives how much of the mineral the compound holds, as US and UK labels list the mineral itself; when only one reading is over the limit, the say line gives both and compared_with.depends_on_label is true. Fish oil, cod liver oil and krill oil amounts are the oil weight, so EPA plus DHA is estimated (amount.epa_dha_estimate_mg). With country=GB the limit is the NHS guidance (compared_with.reference is UK (NHS), with us_upper_limit alongside). For other supplements the answer compares with an official ceiling where one exists (caffeine) or the amounts studies have used, with status above, at, within, above_studied_range, within_studied_range, below_studied_range or no_set_amount, plus cautions. Adult values only, with a note

Supplement Check. Add up everything someone takes and check the daily totals against adult upper limits. Use for "I take Centrum, vitamin D 5000 IU and zinc 50 mg, is that too much?" or "is it OK to take OLLY Sleep with extra melatonin?". Pass up to 6 items separated by semicolons: product names, barcodes, or amounts like vitamin D 5000 IU. Products are counted at the most each label suggests per day. Returns totals (each vitamin and mineral added up, with the items it comes from, compared with the adult upper limit, or NHS guidance with country=GB), other_totals (caffeine, melatonin and similar added up, or marked when a label hides the amount), items (what each was matched to) and not_found. Fish oil amounts count the EPA and DHA they typically hold.

Supplement Check. What a vitamin, mineral or popular supplement does, how much adults need or studies used, limits, cautions and food sources. Use for "what does magnesium glycinate do?", "what is vitamin K for?", "how much vitamin D do I need?", "is ashwagandha safe?" or "what is creatine?". Covers vitamins A, B1, B2, B5, B6, B12, C, D, E and K, niacin, folate, biotin, choline, calcium, iron, zinc, magnesium, potassium, selenium, iodine, copper, chromium, manganese, molybdenum, phosphorus, boron and omega-3, and explains common forms. Also covers creatine, melatonin, caffeine, ashwagandha, turmeric, CoQ10, collagen, protein powder, probiotics, psyllium, glucosamine, St John's wort, green tea extract, berberine, L-theanine and elderberry: for these it returns supplement, what_studies_looked_at, studied_amounts, ceiling, cautions and source instead of rda and upper_limit. Links the NIH fact sheet. With country=GB the answer gives the UK amounts and NHS supplement guidance, also in the uk field.

Supplement Check. A supplement's label: amounts per serving, upper limit check, halal status and a buy link. Use for "what's in Nature Made vitamin D3?", "is Centrum halal?", "how much melatonin is in OLLY Sleep?" or "is this supplement halal?" with a barcode. Give q (brand and product name) or barcode. Returns per-serving amounts, dose_check (each vitamin and mineral compared with the adult upper limit at the most the label suggests per day, with per_day_base amounts), other_checks (melatonin, caffeine, creatine, ashwagandha and similar, including when a blend hides the amount), halal (likely_halal, doubtful, not_halal or depends_on_school, with the ingredients that need a confirmed source), alternatives (other sizes or versions), an Amazon link, and halal_options (links to halal-certified or gelatine-free versions) when the halal answer is not likely_halal. For a general name like "creatine monohydrate" it reads one common label and says so. With country=GB, dose_check uses the NHS guidance where it sets one (upper_limit says NHS guidance). Salt forms such as magnesium glycinate are counted as the mineral they hold (estimated: true), and omega-3 is read from EPA and DHA, total omega-3, or estimated from the fish oil weight.

Sync My Cycle. Today's cycle phase, with workout and food ideas. Use when the user asks what phase they are in, what workout or food suits them today, or why their energy is up or down, for example "what phase am I in, my last period started September 12th" or "what should I train today?". Needs the first day of their last period. Not for getting pregnant, fertile days, ovulation timing, contraception or pregnancy: this is general wellbeing only, not for pregnancy planning or contraception, so suggest a doctor or pharmacist. When `period_may_be_late` is true the say line says the period may be late and suggests checking with a doctor

Sync My Cycle. The days ahead by phase. Use when the user wants to plan training or meals for the week, for example "plan my training this week around my cycle". Returns each day's likely phase, workout focus, intensity and food focus. Not for getting pregnant, fertile days, ovulation timing, contraception or pregnancy: this is general wellbeing only, not for pregnancy planning or contraception, and it is not a fertility calendar. When `period_may_be_late` is true, `days` is empty and the say line suggests checking with a doctor

Sync My Cycle. What each phase usually feels like, with workout and food ideas. Use for general questions about cycle syncing that need no dates, for example "what should I eat in my luteal phase?". Not for conception, fertile days, contraception or pregnancy: general wellbeing only, not for pregnancy planning or contraception

Wardrobe Connect. Find clothes that match a description. Use when the user describes a piece of clothing they want ("black pleated wide-leg trousers", "cream cable-knit jumper like the one I saved"). Natural requests are fine ("a navy midi wrap dress for a summer wedding under £60 in a size 12"): the occasion is kept out of the search and returned in `occasion`, and a price or size in the words is used when max_price or size is not passed. Returns eBay listings in the Clothing, Shoes and Accessories category, closest matches first and then cheapest first (from a best-match and a price-sorted search), plus search links for other shops and a Facebook Marketplace search phrase. Listings must match the colour and fabric named, the same kind of garment (by title and by eBay category, so socks never answer a search for trainers), and men's or women's if given; kids' items only when asked for. Adult, fetish and costume listings are never shown, repeat listings of the same item count once, and listings far below the typical price for the search (usually bait or junk) are left out

Wardrobe Connect. Find clothes that look like a picture. Use when the user shares or points at a picture of an outfit or item (a Pinterest pin, a saved post, a photo). Give the image's direct https link. Returns visually similar eBay listings from the Clothing, Shoes and Accessories category only, in eBay's look-alike order. If the picture does not look like one piece of clothing (the results are scattered across unrelated kinds), `matches` is empty and the say line asks what the item is. Adding a short description in q is strongly recommended: results must then match it, which removes look-alikes of the wrong kind
