The Ingredients in our Night Time Complex

Our formula features a powerful blend of natural ingredients, delivered in clinically-effective doses, that help enhance sleep, improve energy levels and reduce fatigue.

L-Tryptophan 100mg

L-tryptophan is an essential amino acid naturally found in many plant and animal foods. It cannot be synthesized by the human body, so it has to be obtained through diet. The body converts this powerful amino acid into serotonin, vitamin B-6, and melatonin after consumption.

B Vitamins

Frequently Asked Questions

If you can’t find the answer below, please don’t hesistate to Contact Us.

What ingredients does this product contain?

List of ingredients: rice flour, magnesium oxide, Montmorency cherry extract (Prunus cerasus, fruit), glazing agent (hydroxypropyl methylcellulose), L-tryptophan, hops flower extract 10:1 (Humulus lupulus, flower), chamomile extract extract 4:1 (Matricaria chamomilla, flower), lemon balm extract 4:1 (Melissa ocinalis, leaf), zinc citrate, pyridoxine hydrochloride (vitamin B6), California poppy extract 4:1 (Eschscholzia californica, aerial part), pteroylmonoglutamic acid (folic acid), methylcobalamin (vitamin B12)

How many capsules should I take each day?

We recommend that you take 2 capsules of our Night Time Complex daily shortly before bed time.

Why is there no melatonin in your product?

Rather than include melatonin directly in our product, we include ingredients that your body can naturally turn into seratonin/melatonin at the amounts it requires. Directly supplementing melatonin is now illegal in the UK unless via a doctors prescription.

Many melatonin products on the market are unsafe, make false claims, and do not contain the amounts indicated on the label. In our opinion, it's much safer to include ingredients such as Hops Extract and Montmorency Cherry, which your body can then use as needed.

Is it vegan and vegetarian friendly?

Our Night Time Complex is suitable for vegetarians, but not for vegans. We use an HPMC capsule shell, rather than an animal-based gelatin shell.

Will the Night Time Complex make me feel drowsy during the day?

No. The ingredients in our Night Time Complex have been carefully chosen because they are natural, effective, and won’t cause drowsiness during the daytime. Our formula will simply help you to get a more restful sleep.

What is Theonia’s return policy?

We offer a 60 day money-back guarantee. If you would like to return your order, then please reach out to us and we will issue you a returns number to include with the package being returned along with further instructions.

When will my order be dispatched to me?

Your products will be dispatched within 1 working day of placing your order.
