Dear Biology

Dear Biology is melatonin-free and designed to support restful sleep—not leave you feeling “knocked out.” Because it contains no added melatonin, it avoids morning effects specifically caused by supplemental melatonin. Everyone responds differently, however, so we can’t promise a completely grogginess-free morning. Take only as directed and allow yourself a full night to sleep.

Dear Biology is formulated to fit into a consistent nightly routine when used as directed. Because it contains active botanicals, amino acids, vitamins, and minerals, check with your healthcare professional before regular use if you take medication, use other sleep products, or have a medical condition. Do not use during pregnancy or while breastfeeding.

Because real life doesn’t follow a perfect 30-night schedule. Twenty-five servings cover most weekday nights while leaving flexibility for weekends, evenings out, travel, family plans, late movie nights, or any night when your normal routine changes. You can use Dear Biology on the nights you need support without feeling pressured to maintain a perfect nightly streak.

Individual responses vary. Some people may notice support early, while others may benefit from more consistent use. Take one stick approximately 30 minutes before bed and pay attention to all three parts of your night: how easily you settle, how well you stay asleep, and how restored you feel in the morning.

Juicy peach with a smooth, tropical mango finish. It’s light, refreshing, and designed to feel like a nighttime treat—not another supplement you have to force down.

Possibly, but check the labels for overlapping ingredients first. Dear Biology already contains magnesium, zinc, vitamin B6, ashwagandha, L-tryptophan, GABA, and other active ingredients. If you take medication or use another sleep or calming product, speak with your doctor or pharmacist before combining them.

Every batch is tested for safety, purity, consistency, and ingredient integrity. Independent third-party certification is currently in progress, and we won’t display a certification mark until that process is complete. Dear Biology is manufactured in an FDA-registered facility that follows Good Manufacturing Practices. FDA registration does not mean that the facility or product is FDA approved.
