What Vitamins Are Found in Canned Tuna Fish?
Canned tuna fish contains several essential vitamins, including Vitamin D, Vitamin B12, and niacin (Vitamin B3).
- Vitamin D
- Vitamin B12
- Niacin (Vitamin B3)
- Vitamin B6
- Folate (Vitamin B9)
The presence of these vitamins makes canned tuna a nutritious food choice. However, opinions may vary regarding the choice of tuna due to concerns over mercury levels, which can impact health benefits.
1. Vitamin D:
Vitamin D in canned tuna contributes to bone health and immune function. It helps the body absorb calcium and phosphorus, which are essential for maintaining strong bones. A 2013 study published in “The American Journal of Clinical Nutrition” states that nearly 40% of Americans are deficient in vitamin D. Since canned tuna is a fatty fish, it contains a significant amount of this vitamin, aiding in daily intake.
2. Vitamin B12:
Vitamin B12 is vital for red blood cell formation and neurological function. Canned tuna is an excellent source, providing several times the daily recommended amount in a single serving. According to the National Institutes of Health (NIH), vitamin B12 deficiency can lead to anemia and neurological issues. A 2016 study by the Journal of Nutrition found that individuals who regularly consume tuna have higher levels of B12.
3. Niacin (Vitamin B3):
Niacin supports energy production and the functioning of the nervous system. Canned tuna is a rich source of niacin, which helps convert food into energy. The NIH indicates that adequate niacin consumption can reduce the risk of heart disease. A 2015 study highlighted that individuals who consume niacin-rich foods like tuna may have improved cholesterol levels.
4. Vitamin B6:
Vitamin B6 is involved in protein metabolism and cognitive development. It plays a critical role in producing neurotransmitters, which are chemicals that transmit signals in the brain. According to the European Food Safety Authority (EFSA), adequate vitamin B6 intake supports immune function and mood regulation.
5. Folate (Vitamin B9):
Folate is crucial for DNA synthesis and repair. While canned tuna contains lower amounts of folate compared to other food sources, it still provides some benefits. The CDC emphasizes the importance of folate for pregnant women, as it prevents neural tube defects in developing unborn babies.
In summary, canned tuna fish offers a variety of vitamins that contribute to overall health, but individuals should consider mercury content when consuming it regularly.

Canned tuna can contribute to achieving the recommended daily intake of thiamine, which for adults is 1.1 mg for women and 1.2 mg for men. -
Vitamin B3 (Niacin):
Vitamin B3, or niacin, contributes to metabolic processes and is important for DNA repair. Niacin helps convert food into energy and is essential for maintaining healthy skin and nerves. The NIH recommends that adults consume 14-16 mg of niacin daily. Canned tuna is a good source of niacin, providing approximately 20 mg per serving, thus exceeding the daily requirement for most adults. High niacin intake can also help lower cholesterol levels, according to findings in the American Journal of Clinical Nutrition (2013). -
Vitamin B6 (Pyridoxine):
Vitamin B6, known as pyridoxine, is vital for protein metabolism and cognitive development. It assists in neurotransmitter synthesis, which affects mood regulation. The NIH states that the recommended daily intake for adults is 1.3-2.0 mg. A serving of canned tuna offers around 0.6 mg of vitamin B6. Regular consumption of this vitamin may reduce the risk of depression, as supported by research published in the Journal of Psychopharmacology (2017). -
Vitamin B12 (Cobalamin):
Vitamin B12, or cobalamin, is crucial for red blood cell formation and neurological function. It supports DNA synthesis and is primarily found in animal-derived food sources. According to the NIH, adults need about 2.4 mcg of vitamin B12 each day. Canned tuna is an excellent source, providing approximately 3.5 mcg per serving. Insufficient B12 intake can lead to anemia and neurological issues, reinforcing the importance of including sources like canned tuna in one’s diet. A study in the American Journal of Clinical Nutrition (2009) highlights the connection between adequate B12 levels and cognitive health in older adults.
How Does Canned Tuna Fish Contribute Vitamin D to Your Diet?
Canned tuna fish contributes vitamin D to your diet in several ways. First, canned tuna is a good source of vitamin D. This vitamin supports bone health by helping the body absorb calcium.

A 100-gram serving of canned tuna typically provides about 60 micrograms of selenium, which is more than the daily recommended intake for adults. Selenium-rich foods may lower the risk of certain cancers and improve immune function, as noted in a 2016 study by Yang et al.
-
Magnesium: Magnesium is another critical mineral included in canned tuna. It supports muscle and nerve function, blood sugar control, and blood pressure regulation. Canned tuna contains roughly 30 milligrams of magnesium per 100 grams. According to the National Institutes of Health, a diet high in magnesium can reduce the risk of heart disease and support bone health.
-
Phosphorus: Phosphorus is significant in forming bones and teeth. Canned tuna offers about 200 milligrams of phosphorus per 100 grams. According to Holick (2010), phosphorus works closely with calcium to maintain strong bones and teeth. A balance of these minerals is crucial for bone density and overall skeletal health.
-
Potassium: Potassium is vital for heart health, helping to regulate blood pressure. Canned tuna provides approximately 250 milligrams of potassium per 100 grams. The American Heart Association states that a diet high in potassium can counteract some of the detrimental effects of sodium on blood pressure.
-
Calcium: Although canned tuna is not as high in calcium as other sources like dairy, it still contributes to daily intake. A typical serving has about 5 milligrams of calcium. Adequate calcium intake is essential for maintaining strong bones and proper nerve function.
In summary, canned tuna fish encompasses various minerals. These contribute to its health benefits, supporting overall well-being in numerous ways.
How Much Selenium Is in Canned Tuna Fish?
Canned tuna fish typically contains between 50 to 90 micrograms of selenium per 100 grams. This amount reflects the average concentration of selenium found in different types of tuna, such as light and white tuna. The actual selenium content can vary based on factors such as the species of tuna, the diet of the fish, and the water’s selenium concentration in their habitat.
Light tuna, often composed of skipjack tuna, generally has lower selenium levels, averaging around 60 micrograms per 100 grams. In contrast, white or albacore tuna typically contains higher selenium levels, averaging closer to 90 micrograms. These variations arise because species like albacore tend to be higher in the food chain, where selenium accumulates more significantly.
For example, a 165-gram can of albacore tuna can provide approximately 150 micrograms of selenium, fulfilling more than 270% of the recommended dietary allowance for an adult. In practical terms, this means consuming just one can of tuna can significantly contribute to daily selenium intake, which is essential for various bodily functions, including antioxidant defense and thyroid hormone metabolism.
External factors affecting selenium content include geographic location and environmental conditions. Tuna from selenium-rich waters may contain more of the mineral. Additionally, food processing methods may impact the final selenium concentration in canned products. However, the data should be viewed with caution, as different brands may have varying levels based on their processing standards and the source of the tuna.
In summary, canned tuna is a significant dietary source of selenium, typically ranging from 50 to 90 micrograms per 100 grams. Variations in selenium content depend on tuna species and environmental influences. For individuals seeking to boost their selenium intake, canned tuna serves as a convenient and effective option, but it’s advisable to consider the specific type of tuna and its sourcing for optimal nutritional value. Further investigation into the health effects of long-term tuna consumption, especially regarding mercury content, may also be beneficial.
