Fortunately there are plenty of foods rich in vitamin B12 as well as supplement options available if needed. Keep reading to learn more about what makes vitamin B12 so important and how to ensure you’re getting enough!

What Is Vitamin B12?

Vitamin B12 is a water-soluble vitamin that plays an essential role in the functioning of our bodies. It helps to create DNA and red blood cells, maintain nerve and brain health, convert food into energy, and regulate moods. Without enough Vitamin B12 intake from either dietary sources or supplements, these functions can be impaired over time.

For vegans who do not consume animal products – including dairy or eggs – fortified foods are one way to make sure they’re getting enough Vitamin B12. This could include cereals, nutritional yeast flakes, vegan milk alternatives, meatless burgers, plant-based cheese slices, tempeh bacon strips and other vegan processed goods which have been supplemented with this important nutrient.

As such it’s important for vegans to ensure their diets contain sufficient levels of Vitamin B12 so as not to risk deficiencies down the line. Taking a supplement is also an option if needed; however exploring ways to incorporate more natural sources of Vitamin B12 into your diet is always best. With this knowledge in hand let’s move on to discuss the benefits of Vitamin B12.

Benefits Of Vitamin B12

Vitamin B12 plays a critical role in the human body for many reasons, and it is estimated that one-third of adults are not getting enough. This essential nutrient helps to make DNA, keep nerve and blood cells healthy, support energy production, and even aid in metabolism regulation. Understanding your dietary needs can help ensure you get an adequate amount of vitamin B12 through foods or supplements.

The absorption rates of vitamin B12 vary from person to person depending on age and other factors such as health conditions or medications. In general, older individuals may benefit more from taking supplemental forms since their bodies absorb less naturally occurring vitamins. Vegetarians and vegans also require supplementation due to limited food sources containing this nutrient.

Additionally, some medical treatments can decrease levels of Vitamin B12 which means monitoring your consumption is important on any special diet or if you have certain lifestyle needs. Taking steps to increase your intake by including fortified foods like cereals or almond milk into your meals will give your body the fuel it needs without having to rely solely on supplements.

Sources Of Vitamin B12

Vitamin B12 is an essential nutrient that plays a role in red blood cell formation, neurological function, DNA synthesis and more. Unfortunately, many people do not get enough of this vitamin through diet alone. Fortunately, there are several foods fortified with Vitamin B12 to help meet the daily recommended intake for adults over 19 years old of 2.4 mcg per day. For those following vegan diets or who cannot find animal-based sources of Vitamin B12 naturally occurring in food, these fortified options can be particularly helpful.

Some common examples of fortified foods include nutritional yeast flakes and powders, meat alternatives like veggie burgers or tempeh, plant milks such as soy, almond and coconut milk (check label for fortification information), some breakfast cereals and energy bars. In addition to fortified foods, supplements containing Vitamin B12 can also be purchased over the counter at pharmacies or online if needed. It’s important to speak with your healthcare provider before starting any new supplement regimen to ensure it’s right for you.

Given its importance in the body’s functioning, it’s critical to strive to reach the recommended levels of Vitamin B12 each day – either by adding fortified foods into one’s diet or taking a daily supplement when necessary. As understanding potential risks associated with deficiency is equally as important, let’s now delve into what happens when we don’t get enough Vitamin B12 in our diet on a regular basis.

For vegans and vegetarians who don’t get B12 from animal products, it’s important to understand what these potential deficiencies look like so they can take steps to protect themselves.

It’s easy to miss out on getting enough Vitamin B12 if you’re not eating any meat or dairy. A person with an insufficient amount of this essential nutrient may experience extreme fatigue since it helps create energy for cells throughout the body. Other telltale signs are pale skin, rapid heart rate, confusion, irritability, depression, poor memory and digestive issues such as nausea or diarrhea.

Vitamin B12 Recommendations

It’s true that the majority of people do not suffer from a vitamin B12 deficiency due to their dietary intakes, but this doesn’t mean that everyone can get enough of it through food alone. Our age and lifestyle choices play an important role in how much B12 our body needs. As we age, our bodies become less able to absorb nutrients, particularly B12 which is found only in animal products like meat, eggs and dairy. A vegan or vegetarian diet may also put you at risk for a deficiency as well as certain medical conditions such as celiac disease and Crohn’s disease.

When it comes to meeting your daily Vitamin B12 requirements, there are several options available to ensure you’re getting enough. For adults aged 19–50 years old, the recommended daily intake is 2.4 micrograms per day while pregnant women should aim for 2.6 mcg/day and those who are breastfeeding should strive for 2.8 mcg/day. If you follow a plant-based diet, there are fortified foods and supplements available in stores which provide adequate levels of Vitamin B12 without having to consume animal products.

For most people though, following the basic recommendations outlined above will be more than sufficient when it comes to ensuring they receive their daily dose of Vitamin B12 – something essential in order to maintain proper health and wellness throughout life no matter your age or lifestyle choices. It’s wise however to keep an eye out for potential signs of deficiencies since these won’t always manifest themselves right away; if left untreated they could cause permanent damage or even death over time so taking preventive measures today will help guarantee better health down the line. With all this said let’s look into some common signs of vitamin b12 deficiency next..

Additionally, making dietary changes can also help improve outcomes when paired with medical treatments like oral supplementation and injection therapy.
