Tart cherry, probiotics and sleep: what is worth expecting?

Tart cherry, probiotics and sleep: what is worth expecting?

A food-based sleep solution can sound gentler and more appealing than changing a schedule. But an appealing format does not remove the need for evidence. Research on nutritional sleep aids in athletes is more tentative than many product descriptions suggest.

The evidence in context

A review of 35 studies examined nutrition and sleep in athletes. Evening caffeine was a relevant concern, while evidence for several promoted nutritional sleep aids, including cherry products and probiotics, remained limited or inconsistent. [1]

Athlete studies do not establish the same result in every reader. The review also does not support replacing assessment of a persistent sleep problem with a food or supplement experiment.

Keep the experiment proportionate

If you enjoy a food, enjoyment can be a sufficient reason to include it. Do not turn that preference into an expectation that it will treat poor sleep. Be particularly cautious about paying a premium for a strong sleep claim when the review describes limited or inconsistent findings.

Putting it into perspective

A cherry product may be enjoyable, convenient or simply something you like. Those are different reasons from expecting a reliably improved night. Keep the ordinary food decision separate from the therapeutic promise, especially when a premium price is justified mainly by a claim stronger than the available evidence.
