If You Want More Energy, Eat These 10 Foods Rich in This Essential Vitamin – Yahoo Lifestyle

Abalanced diet is key to maintaining a healthy body and trying to avoid any health issues. We talk about what to eat if you want good skin, better focus, a healthier heart, and so much more. But do you know if you're getting enough of a crucial nutrient: vitamin B12?

"Vitamin B12 is a water-soluble vitamin that plays a major role in DNA synthesis, nervous system function, and red blood cell formation," explains Claire Virga, MS, RDN, of Rooted Wellness. "We need vitamin B12 to keep our nerve and red blood cells healthy and to create new DNA. Our bodies can't make vitamin B12 so we must get B12 from dietary sources and supplements."

The thing is, you might not know you have a deficiencystraight off the bat. "You could have low B12 for years before an actual deficiency symptom shows up," says Robin Foroutan, MD, RDN, HHC, a spokesperson for the Academy of Nutrition and Dietetics.

A deficiency can lead to anemia and nervous system complications that cause symptoms like fatigue, numbness, tingling, muscle weakness, and shortness of breath as well as cognitive complications like memory loss and depression, Virga adds. And if left untreated for a long period of time, it can lead to severe, irreversible nerve damage in some cases.

Since vitamin B12 is found in meat, seafood, and dairy, there are some people with dietary restrictions who are more susceptible to a vitamin B12 deficiencyvegans and vegetarians, for example. "It's probably the most-difficult-to-absorb vitamin, and it's not found everywhere in food," Foroutan says. "Mostly animal foods are sources of B12, but because it's so difficult to absorb, a lot of people end up with low levels even if they might be eating the right amount of B12 foods. The people who are most at risk for B12 deficiencies or chronic low-grade insufficiencies are the vegetarians and vegans, anybody avoiding red meat and people who take acid-blocking medication or routinely take antacids."

Since absorption can be difficult with this vitamin, people withdigestive problems orinflammation in the digestive tract might not be able to absorb it fully. Not to mention as you get older, your ability to absorb B12 decreases. Additionally, pregnant and lactating women may need more vitamin B12 to support the cognitive development and healthy growth of their baby. "A B12 deficiency during pregnancy can cause developmental abnormalities, neural tube defects, preeclampsia, and other complications," Virga says. "Pregnant women should look for a prenatal multivitamin containing vitamin B12."

So how can you make sure you're getting enough B12, even if you're not exhibiting symptoms of a deficiency? A blood test at your doctor's office will let you know. But if you're looking for more sources of vitamin B12 in your life, both Virga and Foroutan shared some common foods below.

"A three-ounce serving of bluefin tuna contains more than 100% of the daily value (DV) of B12," Virga says. "Tuna is also a great source of protein, omega-3 fatty acids, and micronutrients like selenium and vitamin B6."

Virga says most cuts of beef are good sources of vitamin B12, but in particular, the cuts of meat lower in fat (like ground beef and beef short ribs) tend to have higher levels. Foroutan also adds that other sources of meat and cuts, such as lamb and organ meats (liver and kidney) are also high in B12.

The yolk is key here, according to Foroutan. "Two large eggs contain around 40% of the DV for B12," Virga adds. "Hardboiled eggs are one of my favorite on-the-go snacks. Boil eggs at the beginning of the week and store them in the fridge for quick snacks or for adding to salads for extra protein and vitamin B12."

"One three-ounce serving of sockeye salmon contains approximately 200% of the DV for vitamin B12!" Virga says. "Salmon is also an excellent source of omega-3 fatty acids, which we need to support brain and heart health."

Other fish that contain the vitamin include sardines and rainbow trout, according to Foroutan.

These might bea helpful optionfor vegans and vegetarians. "Foods like cereals, non-dairy milks, and vegan spreads are often fortified with vitamin B12," Virga explains. "Fortification of foods involves adding a nutrient to a food that is not naturally occurring in the food."

Anthony's Premium Nutritional Yeast Flakes ($13)

This one's another good choice for vegetarians and vegans. I am neither, but I love using nutritional yeast as a topping on popcorn because it tastes cheesy and nutty. "Nutritional yeast is often fortified with vitamin B12, but the vitamin content varies by brand, so it's important to check the ingredient list to ensure it contains the vitamin," Virga advises.

Virga saysthree ounces of cooked clams contain 3540% of the DV for vitamin B12. And if you don't love clams, Foroutan says other shellfish like oysters and mussels are a good source, too.

"Dairy-based yogurts are also good sources of vitamin B12," Virga says. "Most flavored yogurts have a ton of added sugar, so I recommend going with plain yogurt and sweetening it with fresh fruit."

Horizon Organic 2% Reduced Fat Milk With DHA Omega-3 ($4)

Virga says one glass of cow's milk contains 50% of the recommended dietary allowance for vitamin B12. Drink up!

Tillamook Swiss Cheese Slices ($5)

Yes, please. "One ounce of Swiss cheese contains 0.9 micrograms of B12, which equates to approximately 38% of the DV of B12," Virga says.

For people who might not be able to get their vitamin B12 intake from what they eat alone because they have dietary restrictions, are older, pregnant, or have another condition, you can turn to supplements for help. You'll want to discuss with your doctor the correct dosage and type or brand of vitamin, but Foroutan has some tips. "When you're looking for supplements, there are a lot of different forms of B12," she explains. "The cheapest and most common is called cyanocobalamin. It is not great. It's not well utilized by your cells. So a better one to use is hydroxocobalamin or methylcobalamin. The other thing is that when you get a B12 supplement, you'll see that it's like 10,000 times the recommended daily allowance, and it gives a lot of people pause, like why is this such a mega dose? It goes back to that vitamin not being well absorbed. So the supplements provide a huge dose knowing that you'll absorb just some of it."
