Returns & Refund

Our Commitment to You

We value all our customers and want you to be completely satisfied with our products. While we believe fully in the science behind Zenbev and the studies that back up our formulation, we know that at times, it’s not for everyone. That is why we have made the following commitment to our customers – a guarantee that if you are unhappy with your products within the first 30 days of receiving them, we will refund them in full, at no added cost to you.

Instructions around Initiating a Return

1. Before a return can be processed, you must notify a Customer Care Representative at [email protected], in order to qualify for a refund and to receive return shipping instructions.
2. We ask that you try Zenbev for two weeks before determining that it does not work for you. Some people notice results right away. For others, it can take two to three weeks to stimulate natural melatonin production again and may, therefore, take a little longer than expected.
3. Returns to Biosential will receive a full refund. We do not refund original shipping costs with the return but also, we do not charge a re-stocking fee for reasonable returns.
4. Please allow fourteen (14) business days from the date you ship the package back to Biosential for us to receive the package and complete the returns process. The product must be in its original packaging. You will receive an email confirming the product has been returned successfully and once approved, a refund receipt will be emailed to you.
5. Returns received after 30 days may not be processed and will be returned to you at your cost.

Take Zenbev Drink Mix at night for insomnia, and in the morning for relief of anxiety symptoms.

Start with 1 scoop for three nights. Mix with warm water or your favorite non-caffeinated beverage. Chocolate Zenbev should be mixed in milk, rice milk, soy milk or almond milk for optimal taste. For those who are avoiding liquids before bed, mix with applesauce check out some of our recipes.

Take one half hour before bedtime and do something calming and relaxing (i.e. not mentally stimulating) before retiring to bed. After three nights increase the dosage by half a scoop allowing three more nights to achieve the desired effect. Continue to increase as necessary. Two scoops are usually sufficient for most people, however some individuals require more. Individual requirements are not directly associated with Body Mass, each person’s biochemistry is different.

It usually takes a few doses before its optimal benefit is seen and it continues to work for a few days/nights after it was last taken. One way of optimizing this benefit is to take Zenbev for 5-7 days/nights and then stop it for 2-3 days/nights before resuming again in a similar pattern.

Zenbev can be taken safely on a daily basis and may also be discontinued at any time. Make sure you are taking a B-complex multivitamin as tryptophan will metabolize to vitamin B3 if your body may be deficient.
