The Science Behind It

As we age it takes longer to fall asleep, we wake more often, and we spend less time in deep, restorative sleep — the stage where the body repairs cells and replenishes energy.

Advanced Deep Sleep works on a four-fold mechanism: it helps you relax before bed, recharge with full hours of sleep, repair in the deep-sleep stage, and revitalise so you wake up rested — using natural melatonin boosters and calming botanicals, with no habit-forming ingredients.

Shipping & Returns

We offer tracked shipping on all orders, dispatched within 24 business hours.

UK delivery typically takes 3-5 working days.

Returns are easy — contact info@autoimmuneinstitute.com and we’ll handle everything.

Is It Safe?

Yes — Advanced Deep Sleep is a tested, all-natural formula without the habit-forming effects of many sleep aids. It is vegan-friendly, gluten and dairy free, non-GMO, and made in the UK to ISO 9001 and GMP quality standards.

Keep out of reach of children. If you take prescription medication, have a medical condition, or are pregnant or breastfeeding, consult your doctor or pharmacist before use.

Eight natural sleep ingredients across four targeted blends:

Capsule: vegetarian HPMC (vegan-friendly). 60 capsules per bottle.

Gluten-free, dairy-free, soy-free and non-GMO.

What Sets Our Sleep Formula Apart?

Most sleep aids either knock you out with habit-forming compounds or do barely anything at all. Here’s why Advanced Deep Sleep is different:

Four-Fold Sleep Mechanism

Relax, recharge, repair, revitalise — the formula helps calm the brain before bed, keeps you asleep for full hours, supports the deep-sleep stage where the body heals, and helps you wake up energised.

Non-Addictive By Design

Many sleep aids rely on habit-forming compounds. Advanced Deep Sleep uses a tested, all-natural formula — natural melatonin boosters and calming botanicals without the addictive effects.

Purity You Can Trust

No artificial ingredients, fillers, binders or flowing agents. Gluten-free, dairy-free, soy-free, non-GMO and 100% vegan-friendly — clean ingredients and nothing else.

Made in the UK

Manufactured in the UK to ISO 9001 certification and GMP code of practice, formulated by health experts. Backed by a 90-day money-back guarantee.

What Real Customers Are Saying

Kelly R. customer photo

I tried everything, from exercise to tire myself out, to pills, to teas — and this is the only one that ever worked. I slept through the night like a baby and woke up feeling rested and energised.

Robert S. customer photo

I used to wake up after 4 hours and couldn't go back to sleep at all. I take it 30 minutes before bed and now I easily complete my 7 to 8 hours. A life-saver.

I fell asleep fine but always woke up tired. A friend recommended this and I'm really surprised by the difference — I finally have the energy to function through the day.

What makes Advanced Deep Sleep different?

It combines eight natural sleep ingredients — Valerian Root, Passion Flower, Chamomile, Hops, Lemon Balm, L-Tryptophan, 5-HTP from Griffonia Seed and Vitamin B6 — in one non-habit-forming formula. Vegan-friendly, gluten and dairy free, and made in the UK to ISO 9001 and GMP standards.

Is it habit-forming?

No. Many sleep aids rely on habit-forming compounds — Advanced Deep Sleep doesn’t. It uses a tested, all-natural formula of calming botanicals and natural melatonin boosters, so you can use it nightly without the addictive effects.

How does it actually work?

Through a four-fold mechanism: Relax — valerian, chamomile and passion flower calm the brain in preparation for sleep. Recharge — it helps you stay asleep for full hours. Repair — it supports the deep-sleep stage where the body heals at the cellular level. Revitalise — so you wake up feeling rested, not groggy.

How long until I see results?

Many customers notice they fall asleep more easily within the first week or two. For the full benefits, use it consistently — and you have a full 90 days to decide, backed by the money-back guarantee.

What’s the correct dosage and how should I take it?

Take 2 capsules daily, 30 minutes to 2 hours before bedtime. Do not exceed the recommended amount unless directed by a qualified health professional.

Will I feel groggy the next morning?

The formula supports your body’s own sleep cycle rather than sedating you — most customers report waking up feeling rested and energised, with no after-taste and no morning grogginess.

Is it safe to take with medications?

If you take prescription medication, have a medical condition, or are pregnant or breastfeeding, show a bottle to your doctor or pharmacist before use. Keep out of reach of children.

Do I have to subscribe?

No. No subscription, no auto-ship, no ‘cancel before we charge you.’ One order, one payment — and a 90-day money-back guarantee behind it.
