    Adult Americans are chronically sleep deprived — and the number is rising.*

  • 70 million

    people in the US suffer from a sleep disorder.*

  • Sleep deprivation

    is linked to new health problems, never seen before

The Problem With Melationin Nobody Talks About

Doctor's have been warning against the use of melatonin for daily use.

Brain on melatonin
brain on naturalsleep pattern

Melatonin introduces an external dose of a hormone your body already produces. It may help temporarily, but it doesn’t address the stress, habits, or routines disrupting your natural sleep cycle.

Regular melatonin use isn’t completely risk-free. It can interact with certain medications and may cause headaches, dizziness, nausea, or sleepiness. Its long-term safety also remains unclear.

Melatonin may help you fall asleep, but its effects can continue into the next day. You may wake up feeling drowsy, foggy, and unfocused instead of refreshed.

The all natural formula that helps you fall asleep, stay asleep and wake up refreshed naturally

We took Melatonin out & replaced it with 11 natural ingredients that helps your body get back to natural sleep cycle

  • Vitamin B6

    Vitamin B6

    Supports natural neurotransmitter production involved in rest and relaxation.

  • Magnesium Glycinate

    Magnesium Glycinate

    Helps relax the body and support deeper, more restful sleep.

  • Zinc Citrate

    Zinc Citrate

    Supports healthy nervous system function and natural sleep rhythms.

  • Glycine

    Glycine

    Helps the body wind down and supports restorative sleep.

  • L-Tryptophan

    L-Tryptophan

    Supports the body’s natural production of serotonin and melatonin.

  • L-Theanine

    L-Theanine

    Helps quiet a busy mind and ease you into a relaxed state.

  • GABA

    GABA

    Supports a calmer nervous system to help the mind settle at night.

  • Apigenin

    Apigenin

    A naturally occurring compound that helps support relaxation and calm.

  • Magnolia Officinalis Bark Extract

    Magnolia Officinalis Bark Extract

    Traditionally used to ease tension and encourage nighttime relaxation.

  • Ziziphus Jujuba Seed Powder

    Ziziphus Jujuba Seed Powder

    Helps support a calm, settled state for more restful nights.

  • Ashwagandha

    Ashwagandha

    Helps the body manage everyday stress and unwind before bed.

Glycine helps your body cool—the physical signal that tells your brain it's time for sleep. L-theanine, GABA, apigenin, and magnesium help quiet the mental noise so sleep can begin naturally.

Jujube seed and magnolia bark support your brain’s calming pathways, while ashwagandha supports the stress response that can pull you awake in the middle of the night.

L-tryptophan, P5P, zinc, and magnesium give your body the building blocks it uses to make its own sleep chemistry. Glycine supports deeper sleep—without melatonin or the heavy morning-after feeling.

Frequently Asked Questions

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.

You’re covered by our 90-day money-back guarantee. Take the time to experience Dear Biology as part of your nighttime routine. If it isn’t right for you, simply contact us within 90 days to request your money back—so you can try it without the risk.
