Orders & Products

Everything you need to know about our clean formulas, ingredient safety, and how we craft our on-demand supplements.

We partner with premium, US-based FDA-compliant facilities to produce our formulas. Every single batch is crafted under strict quality control standards, ensuring maximum purity and effectiveness to fuel your discipline.

Are these supplements safe to combine with other products?

Our clean formulas are designed with high bioavailability. However, because everyone's body is unique, we highly recommend reviewing the ingredient list with your healthcare professional before adding new supplements to your routine.

To maintain top freshness, our products are processed on demand immediately after purchase. Because of this fast fulfillment cycle, we cannot cancel or modify orders once they have entered the manufacturing stage.

Shipping & Delivery

Details on our custom manufacturing times, nationwide shipping estimates, and how to track your order.

All O2 Supplements are freshly manufactured on demand. Please allow 2 to 5 business days for our facility to formulate, label, and pack your order. Once shipped, standard delivery takes 3 to 7 business days nationwide.

As soon as your supplements leave our fulfillment facility, you will receive an automated email with your tracking number. Please allow 24 to 48 hours for the carrier to update the tracking information on their system.

O2 Supplements is not responsible for packages marked as "Delivered" by the carrier but not received. We recommend checking with your neighbors or building manager first, and contacting the shipping carrier directly to file a claim.

Returns & Refunds

Clear guidelines on our safety protocols, quality guarantees, and what to do if your package arrives damaged.

Because our supplements are custom-made on demand and classified as perishable nutritional goods, we cannot accept returns, exchanges, or offer refunds for a change of mind, flavor preferences, or selection errors.

If your order arrives broken or defective, we will gladly issue a replacement or refund. Please contact our support team at within 14 days of delivery with your order number and photo proof of the damage.

Many of our bestsellers and core essentials are restocked regularly. Limited edition activewear may sell out quickly, so we suggest signing up for restock alerts.

For strict health and safety regulations, we can never accept returns or offer refunds for any product that has been opened or has its safety seal broken.
