Difference Between Omega-3 and Vitamin D

Omega-3 is a fatty substance known as a polyunsaturated fat. Vitamin D is calciferol, a type of organic micronutrient needed by the body.

What is Omega-3?

Definition:

Omega-3 is a type of polyunsaturated fatty acid that is found in certain animals and plant materials.

Chemical structure and properties:

The molecular formula for omega-3 is C60H92O6. The name omega-3 comes from the location of a double bond between carbons near the tail part of the molecule. Omega-3 is a fatty acid, which means it repels water.

Types of Omega-3:

There is more than one type of omega-3 fatty acids. The three commonly known types of omega-3 include docosahexaenoic acid (DHA), alpha-linolenic acid (ALA), and eicosapentaenoic acid (EPA).

Health benefits:

Some types of omega-3 fatty acids such as DHA and EPA have been shown to help people who suffer from depression. The omega-3 fats also have strong anti-inflammatory properties which helps prevent many types of illness. These fatty acids are also healthy for the brain and heart.

Sources:

There are many different foods that contain good amounts of omega-3 fatty acids. The most familiar food source to most people is fish like herring, sardines, salmon, and mackerel but the fatty acids are also found in walnuts, flax seeds and hemp seeds. 

Deficiency symptoms:

A deficiency of omega-3 may manifest as mood problems, including depression. A lack of omega-3 may leave you feeling tired, having dry skin, and dry eyes, and feeling joint pain.

What is Vitamin D?

Definition:

Vitamin D is a type of fat-soluble vitamin that is also known as calciferol, that is needed in small amounts by the body.

Chemical structure and properties:

The molecular formula for vitamin D is C33H52O7. Vitamin D is fat-soluble. This means that it is stored in the liver along with other fat-soluble vitamins when you have enough of it in the body.

Types of Vitamin D:

Vitamin D comes in two forms, namely D2 and D3. Vitamin D2 is known as ergocalciferol while vitamin D3 is called cholecalciferol. Both types of vitamin D are important for good health.

Health benefits:

Vitamin D plays an important role in the human body. Your bones need phosphorus and calcium to stay strong and healthy and in order to properly absorb and take up these minerals, you also need to have enough vitamin D. Vitamin D also is believed to help the immune system and prevent infection from viruses like Covid-19 and influenza.

Sources:

Exposure to sunlight helps the body to make vitamin D. There are also foods that contain some of the vitamin, for instance, oily fishes like salmon, as well as eggs and liver. Fortified foods which have had vitamin D added are also a source of the vitamin. This includes fortified milk and fortified cereals.

Deficiency symptoms:

A deficiency of vitamin D can result in symptoms like bone and joint discomfort and pain. Muscle pain, exhaustion, and depression can also occur if you do not have enough vitamin D.
