When their kiddos struggle with sleep, many parents turn to any possible solution they can find! One that’s become popular as of late is supplementing Magnesium to support sleep. This follows another trend or using Melatonin to help children relax and fall asleep. Melatonin supplements have occupied a large amount of shelf space for several years, and now Magnesium joins the ranks as a so-called sleep helper. Magnesium comes in many forms- you can find the popular supplement in gummies, powders, lotions and sprays.
About Magnesium’s Role in Your Child’s Body
Magnesium is a mineral that plays an essential role in enabling multiple body systems to function properly. Magnesium supports digestion, energy production, bone development and muscle relaxation. It plays a role in regulating blood pressure and blood sugar.
Kids who are chronically deficient in Magnesium might appear to be hyperactive or anxious. Behaviors stemming from hyperactivity and anxiety can result in bedtime challenges. Since a child with a Magnesium deficiency might exhibit symptoms similar to the symptoms of stress, parents infer that giving a Magnesium supplement will resolve those stress related symptoms. Parents hope that Magnesium will help their hyperactive or anxious child relax and fall asleep.
Magnesium is found in the foods that we eat. Today’s farming soil contains less Magnesium than it did years ago. This might result in Magnesium deficient produce. Today, a large percentage of the population consumes an excess of processed food and carbonated soda. One might find some Magnesium in processed food but not nearly the same amount that a healthy diet provides. Carbonated soda interferes with the ability to absorb Magnesium from the foods that we eat.
Supplementing Magnesium: An Expert’s Take
Dr. Craig Canapari, pediatric sleep medicine doc at Yale, and one of our fav Peapod Trusted Experts, reviewed how, if at all, supplementing Magnesium interacts with sleep- and in which formats it could work best. Here’s a recap of his findings:
- According to Dr. Canapari, the evidence that Magnesium helps kids sleep better is very weak. While some research indicates that Magnesium might help adults sleep better, there are very few pediatric studies that connect kids’ supplementing Magnesium to quantity and quality of sleep in the pediatric population.
- Many Magnesium sprays and lotions will claim they help kids relax and fall asleep more easily. But, when Dr. Canapari’s read the studies, he did not find any research to back it up. If a parent administers a Magnesium spray or lotion and their child falls asleep easily, Dr. Canapari says it’s likely due to a nice relaxing bedtime routine and/or a placebo effect.
- Proceed with caution if you wan to try Magnesium sprays or lotions, Dr. Canapari they could cause itching, stinging and general skin irritation, which could make sleep harder for your kiddo!
When Supplementing Magnesium Might Help
While he’s skeptical about it’s role in sleep medicine, Dr. Canapari shares there are a few conditions where Magnesium supplementation might be beneficial, including:
- Type I Diabetes
- Celiac Disease
- Obesity
- Diarrhea
- Picky eaters (insufficient vegetable intake and an excessive intake of processed food)
If your child’s sleep issues are behavioral supplementing Magnesium won’t help with sleep. In this case, it’s going to work best to create a sleep modification plan and put it to work with consistency. We will always recommend putting a plan into action with consistency as a first line for resolving sleep. If you’re struggling, exhausted and can’t resolve your child’s sleep issues, reach out to a sleep specialist for support.
Solutions to Consider Before Supplementing Magnesium
- Provide your child with a diet rich in Magnesium.The best sources of Magnesium are found in dairy products, leafy green vegetables, whole grains, nuts and seeds.
- Talk to your pediatrician about Magnesium. Magnesium is not regulated by the FDA. There are very few pediatric studies which look at the relationship between Magnesium and sleep and the evidence suggesting that Magnesium helps children fall asleep is very weak. There is no research that addresses potential long-term side effects of Magnesium supplementation.
- Approach behavioral issues with sleep support, whether a DIY method or a personalized plan from Joan.
