Your Rhythm is a supplement, not a treatment for insomnia. Its labeling states that it is not intended to diagnose, treat or prevent disease. Unlike Japan's Foods for Specified Health Uses (FOSHU), its functionality and safety have not been individually evaluated by the government. Manufacturer comparison and labeling

For the medicine's English directions and warnings, see Drewell or Drewell EX.

Deep, Relax and Beauty compared

All three list the same daily amounts of GABA and the two rafuma-derived compounds. Deep does not contain more of these ingredients than Relax or Beauty. Compare the additional ingredients and the functions described on each label rather than treating the names as strength levels.

The descriptions below summarize the notified functional claims. They describe functions reported for the ingredients, rather than promising a particular result for every person. The Consumer Affairs Agency records are Deep — J1537, Relax — J1538 and Beauty — K595.

Ingredients per daily serving of 3 tablets

Rafuma (ラフマ) is a plant ingredient. Hyperoside and isoquercitrin are the two rafuma-derived compounds named on these labels. These amounts refer to 3 tablets, not one tablet. The table lists the functional ingredients; check the full ingredient list if you have food allergies. Deep information, Relax information, Beauty information

How to take Your Rhythm

For all three versions, the manufacturer's suggested daily intake is 3 tablets with water or another suitable drink, without chewing, for example before bedtime. Follow the suggested daily amount.

The packs come in two sizes: 18 tablets for 6 days and 42 tablets for 14 days, based on 3 tablets per day. These are pack durations, not promises about how soon you will notice a change. Official directions and pack sizes

The manufacturer explains that the sleep-quality functions in the research used for the notifications were reported after continued intake over a period of time, and that experiences vary. Its FAQ does not give a fixed number of days for everyone. Manufacturer FAQ on duration

Check these precautions before use

Avoid using Your Rhythm at the same time as sleep-improvement medicines such as Drewell. This is the manufacturer's specific guidance for the supplement series. Manufacturer FAQ on combined use

The following labeling precautions apply to all three supplements:

• They were not developed for people with disease, minors, people who are pregnant, planning pregnancy or have recently given birth, or those who are breastfeeding.
• If you have a disease, consult a doctor before taking them. If you take medicines, consult a doctor or pharmacist. The labels specifically highlight medicines for high blood pressure.
• If you have food allergies, check the ingredient list before deciding whether to use the product.
• If you notice a change in your health, stop taking the supplement promptly and consult a doctor.
• Keep a balanced diet with staple foods, main dishes and side dishes.

Deep and Relax additionally advise medical assessment if you persistently lack vigor or vitality, or fatigue does not improve with rest or sleep, because conditions such as depression or chronic fatigue syndrome may be involved. Deep precautions, Relax precautions, Beauty precautions

Common questions

Does Your Rhythm contain melatonin?

Melatonin is not listed in the ingredients for these three products. Their common functional ingredients are GABA and rafuma-derived hyperoside and isoquercitrin. References to melatonin in explanations of rafuma should not be read as a statement that the tablets contain melatonin. Official ingredient comparison

Is this the same as a milder Drewell medicine?

No. Your Rhythm is a different product category with different ingredients and claims. Use the product name and the Japanese category label to distinguish it from Drewell and Drewell EX. Read the directions on the product you actually buy. Official comparison
