Vitamin D: The Sunshine Vitamin

Sources and Functions

Vitamin D is unique because our bodies can produce it when our skin is exposed to sunlight.[9] It is not found naturally in many foods.[10] Good dietary sources of vitamin D are fatty fish, egg yolks, and fortified foods.[11]

Our bodies transform vitamin D from sunlight or food into an active hormone.[12] This active form of vitamin D aids in absorbing calcium from food.[13] It also supports bone health by contributing to bone strength and maintenance.[14]

Vitamin D has important functions beyond calcium absorption. It also helps with muscle function and strengthens the immune system.[15] Some studies suggest that vitamin D may positively affect mood and brain function.[16]

Benefits for Immune System

Vitamin D is important for a strong immune system.[17] It helps activate immune cells that fight off harmful invaders. Research indicates that individuals with low vitamin D levels may be more likely to get sick.[18]

Researchers have studied the connection between vitamin D and respiratory health. Some findings suggest that people with higher vitamin D levels experience fewer respiratory infections.[19] However, further research is needed to fully understand this connection.

Signs of vitamin D deficiency can include:

• Fatigue
• Bone pain
• Muscle weakness
• Increased risk of fractures
• Frequent infections

Dosage and Safety

The daily recommended amount of vitamin D varies depending on age and other factors.[20] Most adults need about 600-800 IU per day.[21] Some individuals may need more, especially if they do not get much sun exposure.

Too little vitamin D can lead to weak bones and other health problems.[22] However, excessive amounts can also be harmful.[23] Very large doses can cause calcium to build up in the blood, potentially leading to kidney problems.[24]

People who might need vitamin D supplements are:

• Older adults
• People with dark skin

Vitamin B12: Energy and Nervous System Health

Functions in the Body

Vitamin B12 plays a key role in the creation of red blood cells. Without enough B12, the body cannot produce healthy red blood cells. This can cause a type of anemia that leads to fatigue and weakness.

This vitamin also supports nerve function. It helps maintain the myelin sheath, which insulates nerve fibers. Proper nerve function is essential for sensation, movement, and overall neurological health.

B12 is involved in the creation of DNA, which is needed for all cell division. This makes it especially important during periods of rapid growth, like pregnancy and childhood. It also supports the creation of blood cells in bone marrow.

Energy Production

Vitamin B12 helps convert the food we eat into energy that our cells can use. It works with other B vitamins in this process. Without enough B12, people often feel tired and weak.

B12 deficiency can cause fatigue in several ways. It can cause anemia, which reduces how much oxygen reaches tissues. It can also affect nerve function, leading to feelings of weakness and tiredness. Some people report improved energy after correcting a B12 deficiency.

Steps that B12 takes in cellular energy production include:

1. Helps break down fatty acids and amino acids
2. Supports the citric acid cycle, a key energy-producing process
3. Aids in the production of red blood cells that carry oxygen
4. Supports proper nerve function for energy use
5. Helps maintain mitochondrial health

Supplementation for Vegetarians and Vegans

Plant-based diets often do not contain sufficient vitamin B12. This vitamin is mainly found in animal products such as meat, fish, eggs, and dairy. Vegans and some vegetarians may need B12 supplements to prevent deficiency.

B12 supplements come in several forms. Cyanocobalamin is common and inexpensive. Methylcobalamin is another form that some people prefer. Both can be effective when taken in adequate amounts.

When selecting a B12 supplement, consider factors such as dosage and absorption. Sublingual tablets or sprays might be absorbed better than swallowed pills. Some people may need higher doses or injections if they have absorption issues.

Fish Oil: Omega-3s from the Sea

Composition and Sources

Fish oil contains two primary types of omega-3 fatty acids: EPA and DHA. These are long-chain omega-3s that the body can readily use. They are found in fatty fish and the algae that fish eat.

Many types of fish are used to produce fish oil supplements. Common sources include salmon, mackerel, sardines, and anchovies. The oil is taken from the fish and purified for use in supplements.

Fish Type	Omega-3 Content (per 3 oz serving)
Salmon	1.5 g
Mackerel	1.0 g
Sardines	1.2 g
Herring	1.5 g
Tuna	0.2 g

Heart and Joint Health
