Before choosing a supplement containing melatonin, separate three questions: what one capsule contains, the daily amount stated on the label and the circumstances in which it is best avoided. Combining melatonin, valerian and passionflower does not, by itself, demonstrate greater effectiveness. This guide helps you compare the information available and prepare useful questions for a healthcare professional.
What should you look for on the label?
Start with the full ingredient list, then look for the amount of each substance per capsule and per stated daily serving. Check the intended users, warnings and storage conditions too. “Plant-based” may describe the capsule shell or some ingredients; it is not a guarantee that a product carries no risk.
A useful comparison has four columns: ingredient, amount per unit, stated daily amount and associated precaution. If a quantity is missing, record it as “not specified” rather than inferring it from the product name. The French consumer authority explains the presentation rules for food supplements.
What does 1.6 mg per capsule mean?
The NovAging Sommeil Complexe product page describes 60 plant-based capsules, each containing 1.6 mg of melatonin, alongside valerian and passionflower. It does not give the amounts of those two plants. These are the available details, without adding assumptions.
The number 60 describes the contents of the bottle. It does not establish 30 or 60 days of use. Similarly, “1.6 mg per capsule” is not an invitation to take more capsules. Follow the amount and timing on the label; if instructions are missing or unclear, ask for clarification before use.
What can three ingredients tell you?
Several substances describe a composition, rather than a proven synergy for the finished product. Findings obtained with another extract, amount or preparation cannot automatically be applied to this bottle. Comparing names alone leaves out information needed to judge whether two formulas are actually alike.
Valerian and passionflower are therefore identified here as ingredients, without promises about sleep or stress. The ANSES opinion on substances used in supplements highlights the importance of avoiding overlapping use with melatonin. Adding another “night” product should not become an automatic step.
When should melatonin be avoided or discussed with a doctor?
ANSES advises against melatonin supplements during pregnancy or breastfeeding, for children and adolescents, for people with inflammatory or autoimmune diseases, and before activities requiring sustained alertness.
Medical advice is needed if you take medication or have epilepsy, asthma, or mood, behavioural or personality disorders. The agency recommends occasional use. A supplement does not replace a varied, balanced diet, a healthy lifestyle or medical care. Keep the bottle and its instructions available when discussing the product with a professional.
Plan your routine without multiplying products
Before adding a bottle, record bedtimes, waking times, night awakenings and daytime alertness. List the medicines and supplements you already take. This record helps a discussion; it is not a way to diagnose yourself or decide that a particular ingredient is the answer.
The French health insurance service offers practical sleep habits: regular schedules, less screen use before bedtime and a suitable bedroom environment. Seek advice for persistent daytime sleepiness. Do not replace prescribed treatment with a supplement.
Use our guide to building a supplement routine without overlaps to organise your list. Our article on magnesium bisglycinate and sleep also distinguishes composition questions from limits in the evidence. Linking to it is not a recommendation to combine the two products.
Frequently asked questions
Does a bottle of 60 capsules mean 60 days of use?
Not necessarily. Duration depends on the actual label instructions and whether use is appropriate for your circumstances. Capsule count alone cannot determine a suitable duration.
Can I take two capsules because I am sleeping badly?
Do not increase the amount on your own initiative. Two capsules would provide 3.2 mg of melatonin. Persistent difficulties call for professional advice rather than an automatic increase.
Do plant ingredients make the formula suitable for everyone?
No. Read the composition alongside the precautions and the other products you use. Plant origin does not rule out interactions or situations where use is unsuitable.
