Do you have a nutritional deficiency? A vitamin or mineral deficiency is pretty common. Read on to find the signs of vitamin and mineral deficiencies.
you've ever looked at the nutrition label on a jar of multivitamins, you know just how many nutrients are packed into those tiny capsules (or gummies!). But since you
need so many vitamins and minerals to keep us
strong and healthy, how are you supposed to know if and when you need to up your intake of any particular one? And is food first the way to go?
The good news: You don't need to have a blood test every few months to clue you in on if you're nutrient deficient. Your body is actually pretty darn good at alerting you by showing various signs.
The tricky part? Many of the symptoms of nutritional deficiencies may seem normal to you if your body has been running on lower fuel for awhile. Get the details about if feeling tired—or having an odd ache or tingling—is no biggie or is actually a sign of a larger health issue (like an iodine deficiency).
Plus, get recipe ideas to boost your intake of vitamins and minerals the natural way! And if you decide to go the supplement route, find out what vitamin brands dietitians recommend.
Are You Getting Enough Vitamin D?
Before I started eating seafood, it was difficult for me to get enough vitamin D through food—since the main dietary sources are fatty fish like salmon, tuna, and mackerel. Now, I eat seafood several times a week.
Other foods like dairy products (including cheese, fortified milk, and yogurt) and milk
contain small amounts, but when I was a vegetarian I would have to strategically plan what I would eat every day to get enough. Of course, you can take in vitamin D through the sun, but it’s hard
to absorb enough while also protecting your skin.
Vitamin D is important for keeping your bones strong—it helps you absorb calcium and keeps your body’s stores of this and other important bone minerals in check. And studies show it may also help boost your immunity. If you're wondering about vitamin D and weight control, science linking the two is very early and not yet proven.
I've had my vitamin D level tested several times through blood work to see if I was deficient in the vitamin. The results have always landed me in a healthy range—but to ensure they stay there, I make sure I eat vitamin-D-rich foods. And when I was a vegetarian, I took a daily supplement.
Researchers say the best way to absorb a vitamin D supplement is to take it with a meal
containing fat, per a study in the Journal of the Academy of Nutrition and Dietetics.
When volunteers in the United States paired a vitamin D supplement with a meal that had 30% of total calories as fat (so about 120 calories, or 13 grams of fat, for a 400-calorie meal), they
absorbed the vitamin D 32% better, versus folks eating a meal without fat.
If you decide to get tested and come up deficient, your doctor may prescribe a high-dose supplement. But if you land in a healthy range or aren't sure if you already get enough, pick a supplement with less than 1,000 IU vitamin D.
You can choose a capsule or try a liquid formula (such as Nature's Way Vitamin D3), which makes it very easy to control the dose. Most women and men need to take in 600 IU daily—or 800 IU if you’re older than 70.
There are actually two types of vitamin D. Yup! You should look for a supplement containing vitamin D3, which is absorbed more efficiently by the body than vitamin D2.
Because vitamin D is a fat-soluble vitamin, it makes sense that a meal containing fat would enhance its absorption—although this is some of the first research to prove this. One caveat of the study: While scientists tested a supplement containing 50,000 IU vitamin D, a typical dose would contain much less than that. So it’s possible that a fat-containing meal affects the absorption of a smaller amount differently than found in the study findings.
Get a whole list of foods offering vitamin D in my FitnessMagazine.com article. While I always recommend food first, getting vitamin D from food isn't always easy.
Signs of a Vitamin K Deficiency
What nutrient is super important for bone health, cell growth, and blood clotting? Ding, ding ding! It's vitamin K! Vitamin K is a nutrient that goes hand in hand with vitamin D.
Because vitamin K plays so many roles in keeping your body running smoothly, you may feel some not-so-fun side effects if you're not getting enough.
Signs of a Thiamine Deficiency
Are you thinking, "What the heck is thiamine?" If so, you're not alone in wondering about this B vitamin. While thiamine isn't talked about much, that doesn't mean your body can do without it. About 80% of the thiamine in your body lives in your red blood cells.
Also known as vitamin B1, thiamine helps your body use carbohydrates and keeps your nerves functioning at their best. To help you recognize when you're not getting enough, I lay out the signs of a deficiency in my Reader's Digest article, including all the signs and symptoms.
Also find out more about methylated vitamins, including vitamin B-12. These vitamins may be helpful if your body's ability to absorb them is hindered or if you have a lack of intrinsic factor. This may be especially important for pregnant women, who need folate or folic acid.
Should You Take a Vitamin Every Day?
It seems like there's a dietary supplement out there for everything these days. How do you know if you should be adding any of them to your day? If you're wondering, "Should I take vitamins every day?" read on.
As a plant-based dietitian, I try to get most of my nutrients from food. I won't ever tell you not to eat your fruits and vegetables, including your leafy greens!
But what if healthy eating isn't enough? Could a daily vitamin or two help you fill in the gaps if your body is unable to get everything it otherwise needs?
You may be surprised to hear what I have to say about taking dietary supplements. We've talked about a few common deficiencies here, but other ones include calcium deficiency and iron deficiency anemia. I'm breaking it all down in this HuffPost.com article! What about other top supplements, like probiotics?
