Refund Policy

We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.

To be eligible for a return, your item must be in the same condition that you received it — unused and in its original packaging. You'll also need the receipt or proof of purchase (your order confirmation email works).

How to Start a Return

To start a return, contact us at help@sielvane.com with your order number. Please note that returns will need to be sent to the following address:

LAMENTOV LLC, 5830 E 2nd St, Casper, WY 82609, United States

If your return is accepted, we'll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted.

You can always contact us with any return question at help@sielvane.com.

Damages and Issues

Please inspect your order upon reception and contact us immediately at help@sielvane.com if the item is defective, damaged, or if you received the wrong item, so that we can evaluate the issue and make it right. In these cases we will send a free replacement or issue a full refund.

Exceptions / Non-Returnable Items

For hygiene reasons, we cannot accept returns of items that show signs of use. Gift cards and final-sale items are also non-returnable. Please get in touch if you have questions about your specific item.

Exchanges

The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.

Refunds

We will notify you once we've received and inspected your return, and let you know if the refund was approved. If approved, you'll be automatically refunded on your original payment method within 10 business days. Please remember it can take some time for your bank or credit card company to process and post the refund too.

If more than 15 business days have passed since we approved your return, please contact us at help@sielvane.com.

4 Science-Backed Reasons Sielvane Is Different

Liposomal Delivery Designed for Better Absorption

Standard glutathione can be vulnerable during digestion. Sielvane surrounds it with a protective phospholipid delivery system designed to help it survive the journey and reach your cells.

1,155mg — A Meaningful Daily Serving

Each serving provides 1,155mg of a focused liposomal glutathione formula. No pixie-dusted proprietary blend. No token dose. Just transparent, purposeful support.

Direct Glutathione — Not Just a Precursor

NAC gives your body a building block it must still convert. Sielvane provides glutathione itself, giving your body direct access to the finished antioxidant molecule.

Supports Your Liver’s Master Antioxidant System

Glutathione is one of the liver’s most important antioxidants. It helps neutralize free radicals while supporting natural detoxification pathways and cellular defense.

Glutathione isn't one job. It's five.

Customer Reviews

After my fatty liver diagnosis, I wanted something more focused than another generic detox blend. I chose Sielvane because it provides direct liposomal glutathione with supporting nutrients. After using it consistently, my afternoons feel steadier and the routine has been easy to maintain.

Verified Purchase

The constant brain fog and afternoon fatigue were making everyday tasks harder than they should have been. After several weeks of consistent antioxidant support with Sielvane, I started feeling clearer and less drained during the day.

Sara R.

Verified Purchase

I had already tried NAC and an ordinary glutathione supplement, but I wanted direct glutathione with a liposomal delivery system. Sielvane gives me everything in two capsules, without clinic appointments or a complicated routine.
