5 Vitamins You Should Take More Of

Let’s be honest: the supplement aisle can feel like a fluorescent jungle. One bottle promises “glow,” another promises “focus,” and a third looks like it wants to fix your entire personality. But when you strip away the marketing confetti, the real question is simple: which vitamins do people commonly need more of?

The best answer is not “all of them, obviously.” In fact, more is not always better. Some vitamins are easy to overdo, some are better absorbed from food, and some matter most for specific groups, such as older adults, people on plant-based diets, pregnant women, smokers, or people taking certain medications. That means the smartest approach is usually food first, supplements when appropriate, and testing when symptoms or risk factors make it worth checking.

Still, a few vitamins come up again and again in U.S. nutrition guidance because low intake, poor absorption, or higher needs are fairly common. These are the vitamins that deserve extra attentionnot because everyone needs a giant supplement stack, but because many people could benefit from getting more of them through smarter eating, fortified foods, or targeted supplements with medical guidance.

Here are five vitamins worth moving a little closer to the front of your wellness radar.

1. Vitamin D: The Sunshine Vitamin That Often Stays Indoors

If there were a popularity contest for “vitamins Americans often don’t get enough of,” vitamin D would show up wearing the crown and sunglasses. U.S. dietary guidance has long flagged vitamin D as a nutrient of public health concern because intake is often too low, and deficiency or insufficiency remains fairly common in some groups.

Why vitamin D matters

Vitamin D helps your body absorb calcium, which makes it a major player in bone health. It also supports muscle function, nerve signaling, and immune health. When levels run low, people may experience fatigue, muscle weakness, bone discomfort, or frequent falls over time. In severe cases, long-term deficiency can contribute to brittle bones and higher fracture risk.

Why people come up short

Getting enough vitamin D sounds easy until real life shows up. Many people work indoors, use sunscreen appropriately, live in places with limited winter sunlight, or have darker skin, which reduces vitamin D production from sunlight. On top of that, very few foods naturally contain much of it. Fatty fish, egg yolks, and UV-exposed mushrooms help, but fortified milk, fortified plant beverages, and fortified cereals do a lot of the heavy lifting in the average American diet.

Who should pay extra attention

• Older adults
• People with limited sun exposure
• People with darker skin tones
• Adults with osteoporosis risk
• Anyone eating very little fortified dairy or fortified alternatives

For most adults, the recommended intake is typically 600 IU (15 mcg) daily, increasing to 800 IU (20 mcg) after age 70. The catch is that some people do not hit those targets consistently through food alone.

Best food sources: salmon, trout, sardines, fortified milk, fortified soy milk, fortified cereals, egg yolks, and UV-exposed mushrooms.

Bottom line: vitamin D is one of the most reasonable nutrients to discuss with a healthcare professional, especially if you have bone issues, low sun exposure, or symptoms that suggest deficiency. Just don’t treat it like candy. High-dose vitamin D supplements can be harmful when used casually.

2. Vitamin B12: Tiny Nutrient, Very Big Job Description

Vitamin B12 may not get the flashy branding of collagen powders or green gummies, but it quietly handles some incredibly important work. Your body needs it to make healthy red blood cells, maintain nerve function, and help build DNA. In other words, it is not exactly optional.

Why vitamin B12 matters

Low B12 can lead to fatigue, weakness, pale skin, mouth soreness, numbness or tingling in the hands and feet, memory issues, and a specific type of anemia. One tricky part is that neurological symptoms can show up even before anemia becomes obvious. So a “maybe I’m just tired” situation can sometimes turn into “actually, we should have checked this sooner.”

Why people come up short

B12 is found naturally in animal foods like meat, fish, eggs, and dairy. That means strict vegans and some vegetarians can struggle to get enough unless they use fortified foods or supplements. But diet is only half the story. As people age, absorbing B12 from food can become harder. Certain medical conditions that affect the stomach or intestines can also interfere with absorption. Long-term use of medications such as metformin and acid-reducing drugs like proton pump inhibitors may contribute as well.

Who should pay extra attention

• Adults over 50
• Vegans and some vegetarians
• People taking metformin
• People using long-term acid-reducing medications
• People with digestive disorders or a history of GI surgery

The standard adult recommendation is 2.4 mcg daily, which sounds tiny because it is. But absorption is the real story here. Some people may need fortified foods, oral supplements, or, in true deficiency cases, more structured treatment from a clinician.

Best food sources: clams, fish, beef, eggs, milk, yogurt, cheese, fortified breakfast cereals, fortified nutritional yeast, and fortified plant products.

Bottom line: if you are always exhausted, follow a vegan diet, or take metformin or heartburn medicine long-term, B12 deserves a seat at the tableand maybe a lab test.

3. Folate (Vitamin B9): The Cell Builder With Special Importance Before and During Pregnancy

Folate is one of those nutrients that sounds calm and modest until you realize it helps make DNA and supports cell division. Suddenly it feels a lot less like background music and a lot more like the drummer keeping the whole band together.

Why folate matters

Your body needs folate to build genetic material and make healthy red blood cells. Low folate can lead to megaloblastic anemia, fatigue, weakness, and problems with cell growth. Folate becomes especially important during the early weeks of pregnancy, when enough folic acid helps reduce the risk of neural tube defects in a developing baby.

Why people come up short

Many foods contain folate, including leafy greens, beans, asparagus, avocado, citrus, and fortified grains. Even so, women who can become pregnant are advised to get 400 mcg of folic acid daily, because getting enough from food alone can be inconsistent, and the earliest weeks of pregnancy often happen before someone even realizes they are pregnant.

This is why folic acid is one of the rare supplement recommendations that public health guidance states very directly. It is not hype. It is prevention.

Who should pay extra attention

• Women who may become pregnant
• Pregnant women
• People who eat very few vegetables, beans, or fortified grains
• People with alcohol misuse or malabsorption issues

Adults generally need about 400 mcg DFE per day, while pregnancy raises the requirement. Women who can become pregnant are commonly advised to take 400 mcg of folic acid daily in addition to eating folate-rich foods.

Best food sources: spinach, romaine, lentils, black beans, asparagus, avocado, oranges, enriched bread, enriched pasta, and fortified cereals.

Important caution: more is not always smarter. Very high folic acid intake from supplements can mask a vitamin B12 deficiency, so mega-dosing is not a wellness flex.

Bottom line: if pregnancy is possible now or in the near future, folic acid is not the vitamin to “remember later.” It matters before the positive test.

4. Vitamin C: More Than an Orange’s Publicist

Vitamin C has been reduced to “that thing in orange juice” for years, which is deeply unfair. This vitamin does much more than appear in cold-season marketing campaigns.

Why vitamin C matters

Vitamin C acts as an antioxidant, supports immune function, helps your body make collagen, aids wound healing, and improves iron absorption from plant foods. Without enough of it, the body starts to show wear and tear in ways that are not subtle forever. Severe deficiency leads to scurvy, a condition that can cause fatigue, gum problems, bruising, joint pain, and poor wound healing. It is rare in the U.S., but not extinct.

Why people come up short

The usual reason is not a medical mystery. It is low fruit and vegetable intake. People on highly restrictive diets, older adults with poor nutrition, heavy alcohol users, and people who rely on ultra-processed foods can all be at higher risk. Smokers need more vitamin C than nonsmokers because smoking increases oxidative stress and accelerates turnover of the vitamin.

Who should pay extra attention

• People who rarely eat fruits and vegetables
• Smokers
• Older adults with limited diets
• People with highly restrictive eating patterns

Adults generally need about 90 mg daily for men and 75 mg daily for women. Smokers need an additional 35 mg per day.

Best food sources: oranges, grapefruit, strawberries, kiwi, bell peppers, broccoli, tomatoes, potatoes, and Brussels sprouts.

Bottom line: vitamin C is usually easiest to fix through food. A colorful produce routine does more here than a miracle powder with a tropical name and suspiciously happy font.

5. Vitamin K: The Quiet Workhorse for Clotting and Bones

Vitamin K does not get as much hype as vitamin D, but it deserves more respect. It helps your body make proteins needed for normal blood clotting and also supports bone health. That is a pretty solid résumé for a nutrient many people only think about after reading a medication warning label.

Why vitamin K matters

If vitamin K levels are too low, the body can have trouble clotting blood properly. That is one reason newborns receive vitamin K at birth. In adults, severe deficiency is uncommon, but consistently low intake is not exactly a gold-star nutrition pattern either. Foods rich in vitamin K also tend to be the foods many Americans should be eating more of anyway: leafy greens and other vegetables.

Why people come up short

People who avoid vegetables, have fat-malabsorption conditions, or eat highly processed diets may not get enough. But this is a food-first vitamin for most healthy adults, not usually a supplement-first one.

Who should pay extra attention

• People who rarely eat green vegetables
• People with fat absorption disorders
• Adults focused on bone-supportive eating patterns

The daily adequate intake is roughly 120 mcg for men and 90 mcg for women.

Best food sources: kale, spinach, collards, broccoli, Brussels sprouts, cabbage, and soybean or canola oil.

Very important caution: if you take warfarin or another vitamin K-sensitive blood thinner, do not suddenly load up on supplements or dramatically change your intake. Consistency matters more than extremes.

Bottom line: vitamin K is a great example of how “eat your greens” remains annoyingly good advice, no matter how many wellness trends try to reinvent lunch.

How to Get More of These Vitamins Without Turning Your Counter Into a Pharmacy

Start with food patterns, not panic buying

If your diet includes fatty fish, fortified dairy or fortified soy milk, eggs, beans, lentils, leafy greens, citrus, berries, peppers, and a fortified cereal here and there, you are already doing a lot of the right work. Nutrition is usually more about patterns than perfect days.

Use supplements strategically

Supplements can absolutely help, especially for vitamin D, B12, or folic acid in higher-risk groups. But they work best when they solve a real gap. “I saw a bottle online” is not a diagnosis.

Know when testing makes sense

Vitamin D and B12 are common nutrients to discuss with a clinician when symptoms, age, diet, or medications raise concern. Folate questions are also important in pregnancy planning and certain anemia evaluations. Symptoms like persistent fatigue, tingling, easy bruising, frequent falls, bone pain, or poor wound healing deserve real attention.

Common Experiences People Have When They Finally Get Enough of These Vitamins

One of the most interesting things about vitamin intake is that people often do not notice a problem until they begin correcting it. Someone may assume they are “just tired,” “just stressed,” or “just not a vegetable person,” when the real issue is that their diet and lifestyle have quietly left nutritional gaps.

A common example is the office worker who leaves home before sunrise, comes back after sunset, and somehow thinks a five-minute walk to the parking lot counts as a sunlight strategy. When that person improves vitamin D intakesometimes with food, sometimes with a clinician-guided supplementthey may not feel an overnight lightning bolt of energy, but over time they can notice fewer aches, less muscle heaviness, and more confidence that their bone health is not running on vibes alone.

Then there is the longtime vegetarian or vegan who eats thoughtfully but forgets that vitamin B12 is not magically generated by good intentions. Many people in that group feel fine for a long time because the body stores B12, but when levels finally dip, the experience can be sneaky: brain fog, fatigue, tingling, mood changes, or unexplained weakness. After adding fortified foods or supplements, some people describe the change less as “superpowers” and more as “Oh, this is what normal is supposed to feel like.” That is still a pretty good review.

Folate-related experiences are often tied to planning ahead rather than fixing symptoms after the fact. A woman preparing for pregnancy may start taking folic acid because it is recommended, not because she feels different on day three. That is the point. Folate is one of those nutrients where the benefit is often preventive and invisible in the best possible way. You do not always feel prevention working, but that does not make it less important.

Vitamin C is a little easier to notice in daily life because low produce intake often travels with other issues. People who start eating more fruit, peppers, broccoli, and other vitamin C-rich foods often are not only getting more vitamin Cthey are improving overall diet quality. They may notice meals feel fresher, wounds heal better, gums seem healthier, and the iron from beans or lentils is better tolerated nutritionally because vitamin C helps with absorption. Sometimes the “vitamin fix” is really a whole eating-pattern upgrade wearing a citrus-colored disguise.

Vitamin K tends to show up in a different kind of experience: the realization that a plate with actual greens on it can do more than decorate the chicken. People who begin eating spinach, kale, broccoli, or Brussels sprouts more regularly are usually not chasing a dramatic symptom change. They are building a steadier routine that supports normal clotting and bone health. For people on warfarin, the key experience is often learning that consistency beats extremes. A sudden “health kick” with massive green smoothies is not always helpful if medication dosing depends on stable vitamin K intake.

The big lesson across all five vitamins is simple: better intake often feels less like a miracle and more like your body becoming easier to manage. Less guesswork. Fewer strange little warning signs. More nutritional common sense. Which, frankly, is a lot more useful than a neon gummy that tastes like candy and promises enlightenment.

Final Takeaway

If you are wondering which vitamins deserve a little more attention, start with vitamin D, vitamin B12, folate, vitamin C, and vitamin K. These are not random trendy picks. They come up repeatedly because they are either commonly underconsumed, harder to absorb in certain groups, or especially important during specific life stages.

The smartest move is not to collect supplements like trading cards. It is to look at your diet, your age, your medications, your health conditions, and your real risk factors. Then build from there. Sometimes the answer is a better breakfast. Sometimes it is more greens. Sometimes it is a fortified food. Sometimes it is a blood test and a conversation with your doctor.

That may not be as exciting as “one weird capsule changed everything,” but it is a lot closer to how health actually works.
