DR.COMEWIN exists because supplement labels so often say very little. We keep our formulas short, our doses transparent, and print every active ingredient with its exact amount — so what you read on the label is what is in the bottle.
Every batch is tested before it ships, and there is no “proprietary blend” trickery — you can see exactly which actives are in the bottle, and how much.
We keep the range deliberately focused: a short list of formulas covering the four areas customers ask about most — sleep, energy, beauty and digestion.
Every batch is tested so content matches the label. No shortcuts.
Ask us anything about ingredients, sourcing or test results, any time.
No brand mark-up and no middlemen — you pay for the formula, not the packaging.
Focused formulas across sleep, energy, beauty and digestion
Every formula is built for one specific goal. Here is how we approach each one.
Magnesium addresses everyday shortfalls; adaptogens such as ashwagandha help ease the tension you carry to bed. Two formulas, both taken 30–60 minutes before sleep.
Magnesium Complex — 8 Forms, 800mgView formula$26.99
Ashwagandha Gummies — with L-Theanine, Maca & Vitamin D2View formula$28.99Guarana for energy, L-theanine to smooth the curve — without the jittery spike or the mid-afternoon crash.
Energy & Focus Tablets — Mint, Guarana & L-TheanineView formula$21.99Matcha Mind Cognitive Gummies — 250mg CognizinView formula$28.99Five collagen peptides with vitamin C, formulated for daily use — with oral beauty nutrition, consistency matters more than any single dose.
Multi-Collagen Peptides — Types I, II, III, V & XView formula$35.99
Apple Cider Vinegar Gummies — with B-Vitamins & GuaranaView formula$28.99Apple cider vinegar, cleanse and metabolic support — digestion and metabolism are two sides of the same coin. Start with one consistent time each day.
Colon Cleanse & Detox Capsules — Probiotics, Fiber & HerbsView formula$28.99Blood Sugar Complex — 20 Active IngredientsView formula$33.99Supplements are not magic. These three things explain why some products work, and when to take them.
SleepWhile you sleep deeply, your body repairs muscle and clears metabolic waste from the brain
Magnesium takes part in more than 300 enzyme reactions and is key to relaxing nerves and muscle. Our magnesium complex combines 8 forms in one capsule — best taken in the evening with food.

BeautyYour skin renews itself roughly every 4 weeks
Collagen peptides are one of the better-studied oral beauty ingredients, and usually need 8-12 weeks of consistent use. Ours are low-molecular-weight hydrolysed peptides — 3 capsules a day.

FocusCaffeine wakes you up — it does not necessarily help you focus
Our matcha mind gummies deliver 250mg of Cognizin® to support attention, with no caffeine. If what you want is to wind down rather than wake up, the evening ashwagandha gummies are the better fit.
See matcha mind gummies →Our ingredient lists are deliberately short.
Wondering about a specific ingredient? Ask us and we'll tell you whether it is in there, and why.
No artificial colors
Color comes from the ingredients themselves, not from a dye.
No artificial flavors
The fruit taste in our gummies comes from juice concentrates and natural flavors.
No titanium dioxide
We don't use it to whiten tablets or pad an ingredient list.
No high-fructose corn syrup
We do not use cheap sweeteners to make a formula taste better.
Non-GMO ingredients
Core ingredients are non-GMO sourced, and labelled as such.
No filler padding
No fillers added simply to bulk out a capsule.
From incoming ingredients to the moment a box leaves the warehouse, every batch goes through the same five checks.
Incoming ingredients are checked against the supplier's certificate of analysis, then identity-, heavy-metal- and micro-tested. Anything that fails goes back.
Before production we re-verify the formula and how much of each active goes in, so the label matches the batch.
Weight, content uniformity and appearance are sampled throughout blending, filling and tableting.
Finished batches go to an independent lab for potency, microbial and heavy-metal testing. The report is theirs, not ours.
Nothing ships until it passes, and we keep a sample and record from every batch so it can be traced back to the ingredient lot.

Magnesium and ashwagandha work best in the evening with food. Energy and matcha formulas are best in the morning or early afternoon so they don't interfere with sleep. Check each product page for specifics.
If you take prescription medication (especially blood pressure, blood sugar or blood-thinning drugs), or you're pregnant or breastfeeding, speak to your doctor or pharmacist before starting any supplement.
Magnesium and energy formulas: a few days to two weeks. Adaptogens such as ashwagandha: usually 4-8 weeks of consistent use. Collagen's effect on skin and nails: most visible after 8-12 weeks.
Subscriptions get 15% off every order and ship on the schedule you choose. Skip, pause, cancel or swap products anytime — no fees, no penalties.
Allergen information is printed on every label. Our ashwagandha gummies contain a gelatin-based ingredient, so vegan customers should choose the matcha gummies or a capsule formula.
A COA lists what was tested, the method used and the result. Send us the batch code from your bottle and we will pull the matching report.
Unopened, most products keep about 24 months — check the date on the bottle. After opening, store somewhere cool, dry and dark; refrigerate gummies and finish them within the recommended window.
Our formulas are designed around adult doses, so we don't recommend them for children. For children's supplementation, speak to a paediatrician.
