What we sell
What is Osterly Market?
A supplement brand, run out of Michigan by two people. We make everything under our own label and hold it in our own warehouse — nothing here is marketplace resale. Daily foundations, immunity, heart and circulation, joint and muscle, energy and focus. 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?
Packed within one to two business days, then five to ten business days to reach you. Orders placed after 2pm Eastern on a Friday start processing the following Monday. You get tracking by email as soon as it leaves.
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
Can I return something if I change my mind?
No. All sales are final — we do not accept returns or exchanges for change of mind. Please order carefully, and start with one bottle rather than three.
It is not us being difficult. These are sealed products meant to be swallowed. Once a bottle has left our hands we cannot verify how it was stored or whether it was opened, so it can never go back into stock or on to another customer. No supplement seller who takes that seriously would do otherwise. What we do instead is keep the prices as low as we can and tell you the policy plainly before you buy.
What if it arrives damaged, or it is the wrong item?
That is a different thing entirely, and it is covered. Tell us and we will replace it or refund it in full, postage included.
What if my parcel is lost or never turns up?
Also covered. If tracking has not moved in seven business days, email us and we will open an enquiry with the carrier. A parcel confirmed lost is replaced or refunded in full — your choice. Anything that comes back to us as undeliverable is refunded in full as well.
When do I get my money back?
Within three business days of the refund being agreed, 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. A recall is not a return — the all-sales-final policy has nothing to do with it.
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 tazvertising@gmail.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. You can also call us on (989) 640-2074 during those hours.
