What we sell
What is Osterly Market?
A supplement shop. Daily foundations, sleep and calm, energy and focus, immunity, joint and muscle, gut and digestion. Nothing else.
Why do your labels look different?
For minerals we lead with the elemental dose rather than the compound weight. A 1,000 mg magnesium glycinate capsule contains roughly 141 mg of actual magnesium — about 14 percent by weight. Most labels put the bigger number on the front because it looks better. We put the useful one there.
Do supplements work?
Some do, for some things, at some doses. We will tell you what is in the bottle and what the research generally says. We will not tell you it treats anything, because supplements are not medicines and are not intended to diagnose, treat, cure or prevent any disease.
Can I take these with my prescription?
Ask your doctor or pharmacist. Several common supplements interact with prescription medication, and that is not a question a shop should be answering for you.
Do you give medical advice?
No. Nothing on this site is medical advice or a substitute for speaking to a clinician.
Ordering and shipping
Do you charge for shipping?
No. Shipping is free on every order within the United States, including PO boxes. The cost is already in the price, so there is no surprise total at checkout.
How long will my order take?
Up to fourteen days door to door, measured worst case — processing plus transit, not just transit. Most orders arrive well before that.
Can I change or cancel my order?
If it has not shipped, yes. Email us with your order number as soon as you can.
Do you ship outside the US?
Not yet.
Returns
What can I return?
Sealed, unopened items within thirty days of delivery. We cannot accept opened supplements back — once a seal is broken the product cannot be verified or safely resold. That is a safety rule rather than a margin one.
What if it arrives damaged or it is the wrong item?
Tell us and we will replace it or refund it in full, including postage, sealed or not.
Who pays return postage?
You do if you have changed your mind. We do if the item is faulty, damaged or not what you ordered.
When do I get my money back?
Within three business days of your return reaching us, to the original payment method.
Quality and safety
What happens if something I bought is recalled?
We contact everyone who bought it, using the email on the order, and refund it in full and immediately. The thirty-day window does not apply to recalls.
Do you check expiry dates?
Yes. Nothing ships with less than twelve months of shelf life remaining unless the product page says otherwise in plain terms.
Had a bad reaction to something?
Stop taking it and tell us, with the product and lot number from the bottle. We log every report and pass serious ones on as required.
Getting hold of us
When are you open?
Monday to Friday, nine to five Eastern. We reply within one business day.
Can you tell me which supplement to take?
We can tell you what is in each one and at what dose. Which is right for you is a question for your doctor, and we will say so rather than guess.
How do I make a complaint?
By email. Complaints about shipping and complaints about a product are both handled by email rather than by phone, so that there is a written record of what happened and we can act on it. Write to support@osterly.com with your order number, and for a product complaint the lot number from the bottle. We reply within one business day, Monday to Friday, nine to five Eastern.
