Dr. Natasha's Favorite Pediatric Supplements



Children have important nutrient needs to support their growth and development, but ensuring your child is getting proper nutrition can be challenging!  Most of us deal with some level of “picky” eating with our kids.  Ideally, the base of children’s diets would consist of a variety of nutrient-dense foods including lean protein, whole grains, legumes, vegetables, fruits, nuts, and seeds. While obtaining nutrients directly from healthy foods is ideal, supplements can help fill gaps in your child’s diet to support their physical and mental health.


The following are some of the top ingredients recommended on Fullscript for supporting children’s health. 


Magnesium is used by every cell and contributes to more than 300 biochemical reactions in the body. Among its many functions, magnesium helps repair DNA and regulate muscle and nerve function, blood sugar, and blood pressure. Magnesium deficiency may also lead to increased anxiety and sleep restlessness in children. Research suggests that supplementing with magnesium reduces hyperactivity in children with attention-deficit/hyperactivity disorder (ADHD) and may help improve learning and memory.  Magnesium is also a great nutrient to use in children that experience occasional constipation. 

Recommended daily allowances for magnesium:

  • 0 to 6 months: 30 mg
  • 7 to 12 months: 75 mg
  • 1 to 3 years: 80 mg 
  • 4 to 8 years: 130 mg
  • 9 to 13 years: 240 mg
  • 14 to 18 years (female): 360 mg
  • 14 to 18 years (male): 410 mg

Omega-3 fatty acids

As essential fatty acids, omega-3s are necessary for brain and heart health.  Dietary sources of omega-3 fatty acids include fatty fish, grass-fed beef, pasture-raised eggs, and nuts and seeds (e.g., chia, flax, walnuts).  Studies suggest that the omega-3s found in fish, particularly docosahexaenoic acid (DHA), can improve brain function and mood.  The EPA fatty acids in fish oil are great for skin health and inflammation.  If your child isn’t getting enough omega-3 fatty acids from their diet, adding a supplement may be beneficial.

Probiotics may be helpful in easing a number of common digestive issues in children, such as colic, constipation, and diarrhea.  Probiotics are available as drops for infants and in chewable or gummy form for older kids. Lactobacillus rhamnosus GG and Saccharomyces boulardii are two strains that have shown promising effects in preventing diarrhea associated with antibiotic use and treating acute gastrointestinal inflammation that may cause diarrhea and vomiting. Check the label for the strains that fit your child’s digestive needs.

Vitamin D

Commonly referred to as the “sunshine vitamin”, vitamin D is synthesized when the skin absorbs UVB rays from the sun.  Vitamin D functions as a hormone and is essential for several bodily functions, such as maintaining strong bones and teeth, supporting a healthy immune system, and regulating the nervous system.  Bone development is accelerated during childhood, making adequate vitamin D intake especially important.  Despite being located in sunny San Diego, the majority of my patients that don’t supplement with vitamin D do not have optimal levels!

Recommended daily allowances for vitamin D:

  • Infant (0 to 12 months): 400 IU (10 mcg) 
  • Children (1–12 years): 600 IU (15 mcg)
  • Teens (13–18 years): 600 IU (15 mcg)

Providing your child with a daily multivitamin/mineral supplement can help ensure they are meeting their daily nutrient needs. Multivitamins contain essential nutrients for children’s health, including vitamins A, B, C, D, and E, as well as the minerals iodine, iron, and zinc. In addition to improving nutrition status, multivitamins may also improve brain function in healthy children. Multivitamins are often formulated to provide necessary nutrients based on life stage, so be sure to choose a multivitamin specific to your child’s age group.
