You need B12 to make red blood cellswhich carry oxygen through your body. Not having enough B12 can lead to anemia, which means your body does not have enough red blood cells to do the job. This can make you feel weak and tired. Vitamin B12 deficiency can cause damage to your nerves and can affect memory and thinking.

Most people get more than enough B12 from eating meat, eggs, milk, and cheese. Normally, the vitamin is absorbed by your digestive system—your stomach and intestines. Vitamin B12 deficiency anemia usually happens when the digestive system is not able to absorb the vitamin.

This can happen if:. This anemia can also happen if you don't eat enough foods with B12, but this is rare. People who eat a vegan diet and older adults who don't eat a variety of foods may need to take a daily vitamin pill to get enough B Other causes include drinking alcohol and taking some prescription and nonprescription medicines. Vitamin B12 is found in foods from animals, such as meat, seafood, milk products, poultry, and eggs.

And you may want to consider supplements. Now, it's true that most vitamin supplements fail to deliver etoken for tatkal measurable benefit. The U. Preventive Services Task Force says there isn't enough evidence to support even a daily multivitamin to prevent cancer and heart disease.

That's why it's better to think plantsnot pills. Join today and get instant access to discounts, programs, services, and the information you need to benefit every area of your life.

But B12 and D3 are different, for two reasons. First, you can't really get them from plants. And second, as we get older, we begin to develop difficulty absorbing them in their natural form.

This vitamin plays an essential role in nerve function; a shortfall of B12 is associated with depression, dementia and decreased cognitive function, as well as anemia. Unless you're a vegan, getting enough dietary B12 isn't a problem, because burgers, steaks, chicken, eggs, dairy and other animal products are rich in it. But as we get older, our ability to absorb B12 is hindered by changes in our digestive systems, as our stomachs naturally begin to produce less stomach acid. Antacids and diabetes medications can exacerbate the problem.

Digestive issues such as celiac disease also can hinder our ability to access B By age 65, as many as 4 in 10 adults may have gastric issues that hinder B12 absorption. The federal dietary guidelines call for a daily intake of 2. But discuss your diet and your underlying health issues with your doctor before deciding on a B12 supplement.

You can buy pills that deliver up to 1, micrograms per dose, but does it make sense to pay more for a megadose your body doesn't need? As little as 10 to 15 minutes in the direct sun a few days a week can give us most of the vitamin D our bodies need to maintain a healthy immune system, bones and muscles while protecting us from cognitive decline.

So what's the problem? Well, our ability to turn sunlight into vitamin D declines as we age. That's partly because the precursors to vitamin D production found in the skin are reduced. By age 70, our ability to produce vitamin D is about half of what it was at age And unlike B12, D is in scarce supply in our regular diets. Most milk and some juices, milk alternatives and cereals are fortified with D, but other dietary sources — fatty fish like mackerel and sardines, and some mushrooms — aren't exactly a staple in most diets.

As a result, nearly 1 in 4 people in the U. That's a problem: As vitamin D levels decline, the risk of Parkinson'sAlzheimer's and cognitive impairment rises.

Vitamin D also serves as an air traffic controller for calcium, essential for bone health. In one study of adults 50 and older, all of whom had recently fractured bones, 43 percent were deficient in both calcium and vitamin D.

Before you pick up a vitamin D supplement, it makes sense to have a conversation with your doctor. Vitamin D can interact with heart medications, including statins and diuretics. Dietary guidelines call for international units IUs daily of vitamin D and at least after ageThe U. Over the years, numerous U. To complicate matters, there were often different recommended amounts for men and women. For example, the recommended amount for vitamin C for women was 75 mg, but for men it was 90 mg.

So the Daily Values were established to provide one number that would be designated on food labels and on dietary supplement labels. There are four categories of DVs: 1 infants to age 12 months, 2 children ages3 adults and children 4 and over, and 4 pregnant and lactating women. Over the years, the way RDAs were determined changed and expanded, eventually morphing into the currently used DVs.

Keep in mind that the DVs are what the U. Government has determined is the amount just above what is needed to keep from developing a specific nutrient-deficiency disease, such as scurvy from being deficient in vitamin C. Vitamin C was discovered when 18th century British sailors, who had been at sea for months, ran out of fresh fruits and vegetables so their diets consisted of no sources of vitamin C.

Although the recommended amount of vitamin C has increased over the years — the DV is now 90 mg — that may be not the amount needed to support optimal health, and the optimal amount can far exceed the DV.

But one serving of many fruits contains well above the DV too; for example, one cup of guava provides mg of vitamin C — more than percent of the DV. Vitamin C is required for the biosynthesis of collagen and neurotransmitters and for the absorption of iron. Research suggests that the amount typically provided in a good quality dietary supplement 1, mg is needed to support optimal immune function. A loose stool is about the worst thing that can happen from taking too much vitamin C.

Vitamin D is a good example of this. Other examples that often far exceed the DV are Thorne products that contain the water-soluble B vitamins.
