Shipping & returns

When Do Orders Ship Out

Orders placed before 3pm PST will typically (~75% of the time) ship out the same business day. Otherwise they should ship out the following business day. Unanticipated delays are possible so please allow 1-2 business days for your order to ship. We do not ship on Sundays or federal holidays.

How Long Does Shipping Take

Please see below for transit time estimates, this does not include processing time. Packages typically reach the courier within 1-2 business days. The following delivery time estimates are counted in business days (M-F), not calendar days. A shipping confirmation email containing your tracking information will be sent to you after your package has been scanned in by the courier, this can sometimes take an additional business day.

USPS First Class

For packages that weigh 15 oz. or less. Average arrival time is up to 2 – 5 business days with delivery confirmation. Tracking is spotty and arrival time is variable.

USPS Priority Mail

For most packages average arrival time is 2 – 3 business days with delivery confirmation and tracking.  2 – 4 day arrival time is NOT guaranteed, and is only accurate about 70-80% of the time.

UPS Ground & FedEx Ground

For most packages average arrival time is 3 – 6 business days with delivery confirmation and tracking.  3 – 6 day arrival time is NOT guaranteed, and is only accurate about 80-90% of the time.

Why are UPS and FedEx so expensive? Because of Surcharge fees.

Mail Forwarding

We welcome orders from anywhere in the world and do our best to guarantee delivery. However, if you are using a mail forwarding service we cannot guarantee successful delivery to the forwarded mail address, as this is not something we control.

Shipping Restrictions

There are no shipping restrictions on our products in the United States. There may be shipping restrictions on some products, and some products may not be shipped to some international destinations. If you are outside the USA there may be additional importation restrictions, procedures, and fees. It is your responsibility to research and comply with local laws.

Customs Fees & Duties

Many countries have specific import fees, rules, and customs procedures. If a fee or tax is required by your customs or postal carrier, it is your responsibility to fulfill the payment obligation. We cannot illegally declare a lower item value or mis-declare tariff codes.

Customs Delays

If a package is held by customs for inspection it could be delayed for several weeks. You should contact the courier and find out if anything can be done to expedite the process. Typically they will request additional information such as what the product is, what it is for, how much it cost, a copy of the invoice or additional documentation. It is important your answers are consistent with our customs declaration.

Our products are dietary supplements for health and wellness. Values are declared in full and you can provide your order confirmation emails as an invoice. If any other documentation is needed please request the courier sends you a detailed written description via email and forward this to us at so we can prepare it.

If the package was shipped by DHL, UPS or FedEx, then you can call those couriers respectively. If the package was shipped by USPS then custody will be transferred to your local national postal service on arrival to the destination country, as per the Universal Postal Union (UPU) treaty. In that case you will need to call your local postal service. We have provided a list of national postal services and courier contact information below:

USPS Customer Support: 1 (800) 275-8777
FedEx Customer Support: 1 (800) 463-3339
In case customs seizes your package we will offer to ship a free replacement using a different courier and/or declaration. If this replacement is seized we will issue a refund or store credit, less the cost of shipping.

My Package wasn’t Delivered
