Importance of Vitamins for weight loss

It is to be kept in mind that consuming vitamins is not a magic pill that works instantly after consumption.

Although, some researchers have found that certain vitamins benefit to maintain a healthy weight. Many others do not show any significant impact on your weight, and there is not a lot of validity associated with specific vitamins claiming to be beneficial to lose weight.

However, the ones that have proven to help you lose weight effectively are given below:

Vitamin D

Vitamin D is essential for healthy and stronger bones. They help your bones absorb calcium and therefore preventing you from developing skeletal or muscular pains.

Although there is little research backing up the claim for vitamin D contributing to weight loss, studies have found that people with more fat have lower vitamin D than the other way around. It is still unclear that if vitamin D deficiency leads to obesity or vice versa, but there is a likely chance that vitamin D deficiency’s leading cause is lack of activity and dietary related factors (1).

Vitamin D is known to help maintain blood sugar levels, reduce inflammation, and enhance insulin resistance. High blood sugar levels are linked to obesity, which can be controlled by consuming vitamin D (2)

Foods rich in vitamin D are:

  • Fatty fish, for example, salmon tuna, mackerel, and sardines
  • Eggs
  • Cod liver oil
  • Beef liver
  • Fortified dairies, such as milk, certain cheeses and yoghurt
  • Fortified plant-based milk
  • Vitamin D fortified breakfast cereals
  • Certain mushrooms

Vitamin B Complexes

B vitamins, or commonly known as vitamin B complexes include:

  • B-12
  • biotin
  • folate
  • B-6
  • pantothenic acid or B-5
  • niacin or B-3
  • riboflavin or B-2
  • thiamine or B-1

Studies have found that B vitamins, specifically B-12, plays an essential role in boosting metabolism. However, many take B-12 intending to enhance nerve and blood cell function (1.1).

But studies suggesting B-12 and other B complexes helping to lose weight take support for the following reasons:

  • B-6, folate and B-12 work together to metabolize fats and proteins.
  • Thiamine or B-1 also helps in the metabolism of proteins, fats as well as carbohydrates.

Vitamin B complexes Food Sources

B complexes are abundant in the following food source:

  • Beans, lentils, cereal
  • Dairy products
  • Whole-grain foods such as barley and brown rice
  • Leafy green vegetables and nuts

B-12 is found in dairy or meat-based products, such as:

  • Fortified breakfast cereals
  • Fortified milk
  • Nutritional yeast and meat

Vitamin C

Vitamin C has abundant health benefits and is often required to boost the immune system.

They are easily available and pose the least dangers when consumed in excess.

However, vitamin C deficiency can lead to a number of diseases, including scurvy, common cold, and iron deficiency, to name a few.

Certain fruits and vegetables are an excellent source of vitamin C and can be incorporated into the diet very easily.

Vitamin C is especially helpful as they contain anti-oxidant that aims to boost the person’s immunity and make the body powerful against the harmful substances.

They are an excellent energy source and mood lifter, thus perfect for early morning consumption or before a workout to enhance your performance.

Vitamin C Food Sources

Following foods are good sources of vitamin C:

  • Citrus fruits
  • Sweet potato
  • Tomato juice
  • Spinach
  • Green and red pepper
  • Cooked broccoli


Although calcium does not count as a vitamin, they are excellent for weight loss when combined with certain vitamins.

We all know that they play a vital role in making your bones stronger; besides, they are also renowned for controlling blood sugar levels and maintaining a healthy metabolism.

When combined with vitamin D, calcium performs the best in helping to lose weight.

Studies also suggest that people who consume calcium-rich dairy show a healthy reduction in their weight.

Calcium Food Sources

Foods rich in calcium include as follows:

  • milk
  • yoghurt
  • fortified cereals
  • fortified orange juice
  • dark green, leafy vegetables
  • seeds
  • almonds


For many people weight loss is not an easy task.

One must be extremely cautious of their food intake and eat healthily while staying active. Luckily, certain vitamins help with fluctuating energy levels and proper maintenance of metabolism.

Though not all vitamins aid in boosting metabolism and promote weight loss directly, some are significantly effective. Examples of a few of these vitamins are vitamin C, vitamin D, and vitamin B-12.
