It is also known as Ascorbic acid, It plays vital role in growth, development and repair of all body tissues.

It is also involved in many other body functions, Such as formation of collagen which reduces aging effect on skin.

Absorption of iron, Immune system, helps to heal wounds faster and maintenance of bones and teeth etc.

The RDA value is 75-90 milligrams a day for adults. And safe upper limit is 2000 milligrams a day.

“The ideal dosage may be higher than the Recommended Daily Allowance value.” Said by Mark Moyad, MD, MPH, of the university of Michigan.

Our body doesn’t store Vitamin-C hence water Soluble vitamin C must be supplied in diet to maintain healthy levels.

Moyad says taking 500 milligrams a day is safe and more beneficial along with the 5 servings of fruits and vegetables.

It is very difficult to eat 9 servings of fruits and vegetables a day to fulfill daily requirements.

Hence it is highly recommended to take  dietary supplements on daily basis, Because it doesn’t have any side effects if you take non-acidic and buffered form of vitamin.

2) Vitamin D

I am sure that you are trying very hard to lose weight and hence you are doing intermittent fasting.

What if I say, Vitamin D along with calcium helps you to lose more weight.

Yes, you should consider adding Vitamin D supplements in your diet. If you are trying to lose weight and prevent heart disease.

Apart from weight loss it has several other benefits such as fighting disease, reduces depression, boosting immune system.

Our body produces sufficient Vitamin D when  directly exposed to sunlight.

But there are several factors that affect body’s ability to get sufficient Vitamin D from Sun.

Factors like:

  • If you live in a highly polluted place.
  • When you continuously use sunscreen lotions.
  • If you spend more time indoors.
  • You live at a place where you barely get sunlight.
  • If you live in a big city where surrounding buildings block direct sunlight.

These factors can lead to Vitamin D deficiency in ever increasing number of peoples every year.

That’s why it is very important to add Vitamin D supplements in your diet along with sunlight to avoid it’s deficiency.

3) Vitamin B12

Including more proteins in diet helps to build muscle mass

Are you getting enough Vitamin B12?

You need to make sure that you are getting enough so as to live healthy.

The most important things it does for you are, it helps to make DNA and red blood cells etc.

Your body doesn’t make and Vitamin B12 on it’s own, So you have to get it either from animal food products or genuine supplements.

The RDA value is 2.4 mcg if you are an adult, 2.4 mcg in case of Teens and 1.8 for childrens up to 13 years old.

The rich sources of Vitamin B12 are animal food products such as dairy products, eggs, fish, meat and poultry.

And if you are consuming above mentioned food products, Then you definitely getting enough vitamin B12.

In most of the cases if you follow vegetarian diet then you are most likely to get vitamin B12 deficiency.

You should add proper supplements immediately, If you are vegetarian.

4) Probiotics

live bacteria present in probiotics

Probiotics are nothing but the live bacteria and yeasts that are very good for your digestive system.

You must be knowing that our body is full of bacteria whether it is Good or Bad.

Probiotics are considered as “good” or “helpful” because they enhance your digestion and keeps your gut healthy.

Probiotics maintains the balance of “good” and “bad” bacteria, So that it can work as it should be.

5) Magnesium Citrate

If you are someone who is following low carb diet or keto diet, Then you must have suffered from the constipation problem.

Constipation is the most common issue that anyone who is following intermittent fasting faces.

The problem mainly occurs because of lack of fiber intake as you reduce carbohydrates and not drinking enough water.

But when after doing everything correctly, still you face difficulty of constipation.

And you want to have smooth bowel movement, then you need to add Magnesium Citrate supplement in your diet.

One important thing to remember is that you should not use this product too frequently.

Because it causes loss of your normal bowel function and your bowel movement may get dependent on this product.

6) Potassium

potassium source

It is an electrolyte which conducts electrical impulses throughout your body.

Potassium helps for following body functions:

  • Muscle Contractions
  • Nerve Impulses
  • Digestion
  • Heart Rythm
  • Blood pressure
  • pH Balance
  • Normal Water Balance

Our body can not produce potassium on it’s own. So it is very important that you should consume balanced potassium-rich foods.

Consuming too little or too high can lead to long term health problems.

If you are someone who loves to work out hard along with intermittent fasting schedule.

Then it is absolutely necessary for you to avoid deficiency of potassium.

Symptoms of potassium deficiency are as follow:

  • Extreme Fatigue
  • Muscle cramping, weakness
  • Irregular heart beats
  • Constipation, nausea, or vomiting 

If you are doing intermittent fasting, then you are most likely to get potassium deficient.

I am sure that at least for once, you already had a feeling of extreme fatigue and muscles cramps while doing intermittent fasting.

Sources of potassium:

  • Fruits such as kiwi, bananas, oranges, pineapples and apricots etc.
  • Vegetables such as carrots, potatoes and green leafy vegetables.
  • Lean meats
  • Whole grains
  • Beans and Nuts

Most of us get enough potassium, if you eat balanced diet. But incase if you have potassium deficiency then you must add suitable supplement.

7) Electrolyte Powder

Electrolytes are the substances that when dissolved in water, They gets electrically charged and works as a conductor.

You should consume adequate amount of electrolyte solution, It is very essential for human body to work and function well.

Some of the common electrolytes naturally present in our body fluids are:

  • Calcium (Ca)
  • Potassium (K)
  • Sodium (NA)
  • Chloride (CL)
  • Magnesium (Mg)
  • Bicarbonate (HCO3)
  • Phosphate (HPO4).

We often lose electrolytes as we lose body fluids, by reasons such as sweating, diarrhea, vomiting etc.

Sweating is the most common reason for depletion of electrolytes from our body.

When you do activities like hard work out, running, cycling, climbing then you lose too many electrolytes which may create imbalance .

Electrolytes imbalance can cause fatigue, muscle cramps, headaches and seizures in some cases.

So when you are following intermittent fasting, and also including exercise in your schedule then you must include electrolytes in your diet.
