Families tend to eat the same meals, so they often share the same nutrient gaps. The good news: fixing them at the household level, with a few changes to the shared grocery list, helps everyone at once.

What nutrients are most families missing?
The Dietary Guidelines identified calcium, vitamin D, dietary fiber and potassium as nutrients of public health concern because so many Americans, kids and adults, fall short[1]. National survey data show many people don't meet needs for vitamin D, vitamin E, magnesium and calcium from food alone[2]. Food comes first; a multivitamin can help fill some gaps[3].
Caveat: Falling short of a recommended intake isn't the same as a deficiency. Only a clinician (and sometimes a blood test) can confirm that.

Which nutrients do kids and adults both tend to miss?
The Dietary Guidelines for Americans, 2020–2025, flagged four "nutrients of public health concern" because low intakes are widespread and linked to health problems: calcium, vitamin D, dietary fiber and potassium[1]. They also flagged iron as a concern for some groups, such as young children and people who are or may become pregnant.
An analysis of national NHANES data found that large shares of Americans took in less than the estimated average requirement from food for vitamin D, vitamin E, magnesium and calcium, even counting fortified foods[2]. Our post on common nutrient gaps in kids covers the children's side; here we'll look at what the whole household can do.
Why do families share the same gaps?
Households share grocery lists, meals and habits. If milk has been swapped for sweetened drinks, the whole family loses calcium and vitamin D. If vegetables rarely make it onto the dinner table, everyone runs short on fiber and potassium. And kids tend to eat what they see their parents eat.
That's why household-level fixes work well: change the shared shopping list and every plate improves.
What foods close the most common gaps?
| Nutrient | Family-friendly food sources |
|---|---|
| Calcium | Milk, yogurt, cheese, fortified soy milk, canned salmon with bones, tofu made with calcium[4] |
| Vitamin D | Fortified milk and some fortified cereals, salmon and other fatty fish, eggs (few foods contain it naturally)[5] |
| Fiber | Beans, lentils, oats, whole grains, fruit, vegetables |
| Potassium | Beans, potatoes, bananas, yogurt, leafy greens, tomatoes |
Simple swaps: milk or water instead of sugary drinks at meals, beans added to tacos and soups, oats for breakfast a few days a week, and one extra vegetable at dinner. Our family grocery list builds these in, and how much fiber you need per day has targets.
Can a multivitamin fill the gaps?
Partially. Supplements can raise intakes of some nutrients that food misses; NHANES data show that supplement users were less likely to fall short on several vitamins and minerals[2]. But supplements don't add fiber or potassium in meaningful amounts, and many multivitamins contain little calcium, so food still has to do the heavy lifting there.
There's also a flip side. In a study of U.S. children and teens, supplements helped some reach adequate intakes, but some young supplement users exceeded the upper limits for certain nutrients[6]. That's why each family member should take a product dosed for their age, and why stacking several supplements needs a closer look. See taking a multivitamin with other supplements and how vitamin needs change with age.
The honest summary
- Calcium, vitamin D, fiber and potassium are common shortfalls for kids and adults.
- Families share gaps because they share groceries and habits.
- Food-first swaps help everyone at once.
- A multivitamin can help with some vitamins, but not fiber, and should be age-appropriate.
Our option
Vita Globe Family Wellness Bundle
The Family Wellness Bundle pairs our Adult Multivitamin Gummies (two gummies once daily, with vitamins A, C, D, E, B6, folate, B12, biotin and pantothenic acid plus zinc and iodine) with our Kids' Multivitamin Gummies (one gummy daily for ages 2–3, two for ages 4 and up, preferably with a meal). Each formula is dosed for its own age group, and both are tested by an independent third-party lab. Both formulas include vitamin D and vitamin C, and each person gets a serving matched to their age group. Neither lists calcium, fiber or potassium, so the food swaps above still matter.
Frequently asked questions
What is the most common nutrient deficiency in the U.S.?
Low intakes of vitamin D, calcium, fiber and potassium are widespread[1]. For true deficiency, iron deficiency is among the most common, particularly in young children and women of childbearing age[7].
Should the whole family take vitamin D?
Many people get too little from food[5], but needs and safe amounts vary by age. Talk to your pediatrician and doctor before adding a single-nutrient supplement.
Can kids and adults share the same multivitamin?
No. Adult products can exceed children's upper limits for some nutrients. Use the one dosed for each age group. See adult vs. kids multivitamins.
How do I know if my family is missing nutrients?
Track what you eat for a few typical days and compare it with the food groups in the Dietary Guidelines. If you're worried about a specific deficiency, ask your doctor about testing.
