Cutaneous manifestations associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. A diagnosis of vitamin B12 deficiency is often overlooked in its early stages because these signs are not specific to vitamin B12 deficiency alone.
Organ meats and shellfish are the richest dietary sources, with a 3-ounce (85 g) serving of cooked clams providing approximately 84.1 µg, while beef liver contains about 70.7 µg. Fatty fish, such as trout and salmon, supply 5.4 µg and 4.8 µg per 3-ounce serving, respectively.
The worst symptoms of B12 deficiency involve severe neurological damage, including severe memory loss, confusion, dementia, psychosis, hallucinations, balance problems, trouble walking, and irreversible nerve damage (neuropathy), alongside serious mental health issues like severe depression or irritability, with physical signs including extreme fatigue, pale skin, and a sore, smooth tongue. These severe cognitive and neurological issues are the most concerning because they can become permanent if left untreated.
Active B12 is generally considered to be the best form of B12 for seniors for several reasons. Metabolically active forms of B12 such as methylcobalamin and adenocobalamin require no further conversion in the body.
In fact, some studies have even suggested the opposite. For instance, one study noted that individuals who regularly took vitamin B12 supplements gained between 2.5 to 17 fewer pounds (1.2 to 7.7 kg) over a decade than those who didn't supplement.

People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
Because up to 30% of adults over 51 years of age have atrophic gastritis with low stomach acid excretion, it is recommended that they meet the RDA for vitamin B12 with supplements and/or fortified foods.

However, if you are looking for Vitamin B12-rich fruits, some studies suggest that certain vitamin B12 fruits, such as bananas, apples, and berries (blueberries and strawberries), can increase vitamin B12 levels. No significant B12 content is present in these fruits to meet your needs.
