Vitamin B12 is an essential vitamin needed to form red blood cells and prevention of anaemia. B12 is found in fish, meat, eggs, and dairy products. When you follow a vegan diet, you are at risk of developing a B12 deficiency which can lead to extreme fatigue, depression, mouth pain and headaches. It is important to take this vitamin supplement to ensure your red blood cells can develop the way that they should.
Vitamin D plays the role of absorbing calcium in the body, which helps keep bones strong and healthy, and reduces the risk of osteoporosis. Unfortunately, there are few foods that naturally contain vitamin D, which can lead to deficiencies. If you are following a vegan diet and are not exposed to the sun often, it may be beneficial to take a vitamin D supplement.
Omega-3 is an energy source that keeps heart, lungs and immune system properly functioning. Omega- 3 is predominantly found in fish. When your body lacks this nutrient, it can impact memory, dry skin and mood swings.
Iron carries oxygen from the lungs to the rest of the body. Foods such as red meat, seafood and beans are high in iron. However, when iron is lacking in the body, there is a lack of red blood cells to carry oxygen which leads to fatigue and lack of motivation/energy.
