Vitamins In Ayurveda – Sources, Functions, Deficiency Disorders

By Dr. Regina Antony
In modern science, food articles are primarily classified based on its constitution, like carbohydrates, fats, proteins, vitamins, minerals etc.
In Ayurveda, the classification of foods is done on the basis of tastes – sweet, salt, sour, astringent, bitter and pungent.

Ayurveda considered food substances as a whole.
For example, red variety of rice was mentioned as a food item that can be consumed on a daily basis. It was considered as a wholesome food.
Modern science states that rice contains carbohydrate and starch in plenty and vitamins, minerals and protein in small quantity.

Can Vitamins Be Ayurvedic?

Can Vitamin supplementation be part of Ayurvedic treatment protocol?
Answer by Dr JV Hebbar: 
Vitamins are part of our diet and activities (Vitamin D – sunlight exposure), which are essential for the body to perform optimally. 
Ayurveda categorizes food and nutrition based on the tastes. Ayurveda mentions that the food should have all the six tastes. This implies that a healthy balanced diet consisting of vitamins, proteins, fats, carbohydrates, minerals and water, is recommended by Ayurveda. 
Decrease of vitamins certainly causes diseases. Eg: Decrease in Vitamin D causes low bone density, increased risk of blood pipe and heart disorders,  cognitive capabilities in elderly people.
It has been clearly observed that the supplementing the depleted vitamin leads to preventing / curing of the disease. Because of these reasons, I strongly believe vitamins can be part of Ayurvedic medicine protocol. 

Better to undergo blood test for vitamins, under professional guidance to determine which particular vitamins to supplement and in which dose. 
Better to supplement the vitamins for the prescribed period only. Better to avoid over-supplementation which may cause increased vitamin levels, which is also harmful to the body. 

Some may argue that because vitamins are not mentioned in ancient Ayurvedic text book, we should not consider it. But Ayurveda, since thousands of years has always incorporated new research and findings to its fold and vitamin supplementation follows the rule of Kshaya – Vriddhi – Samanya Vishesha thepry of Ayurveda – depletion, cured by supplementation. 

Ayurveda and vitamins

Vitamins and minerals were not mentioned as separate entities in Ayurveda, but the foods that have been mentioned as healthy and ideal for daily consumption is found to contain all the essential vitamins and minerals.

How Ayurveda tackles vitamin deficiency?
Vitamin deficiency is not just caused due to lack of vitamins in diet. Problems in absorption of vitamins is the main cause of vitamin deficiency. This is the reason, well nourished persons are also often diagnosed with deficient vitamins. This is the reason, people with metabolic disorders such as obesity, often suffer with vitamin deficiency. (1)

Digestion process correction

Correction of digestion mechanism:
So, digestion and absorption mechanism should be corrected first. Altered digestion process can be cause for vitamin deficiency. It is proven that people with Irritable bowel syndrome suffer with vitamin deficiency (2)

Ayurveda calls digestion process as Agni.
In Ayurvedic treatment for vitamin deficiency, initial emphasis is given to improve the digestion strength. Correction of digestion process with respect to liver, pancreas, stomach and intestines leads to proper Agni and good absorption of consumed vitamins.
For this purpose, below Ayurvedic medicines are used –
Agnitundi vati
Chitrakadi Vati
Arogya Vardhini Vati – when liver enzyme / bile secretion correction is required
Mustharishtam – when digestion process correction along with diarrhea, as in case of IBS-D is involved.

Treatment for liver

Liver correction:
Fat soluble vitamins – A, D, E and K require bile, secreted by liver for their absorption. Hence, liver function correction is emphasized.
It is done with Ayurvedic medicines like –
Arogya Vardhini vati
Patola Katu Rohinyadi Kashayam
Vasa Guluchyadi Kashayam etc

Treating underlying disease:
The underlying diseases should be treated (such as diabetes) so as to improve vitamin absorption.

Panchakarma – detoxification therapies:
Panchakarma help to get rid of toxins at once. Once the whole body is detoxified, all hassles in the absorption of vitamins (and other nutrients) are taken care.

Vitamin rich foods:
Once after the digestion process and underlying diseases are treated, then Vitamin rich foods are given to the patient.

Foods Vs supplement:
Initially, to ensure quick recovery, Ayurveda recommends using vitamin supplements for a period of 4 – 8 weeks.
Once after the normal values are restored, then patient is encouraged to have vitamin rich foods.

What are vitamins?

Vitamin is an essential micro-nutrient that an organism needs in very small quantities for the proper functioning of the body. Essential nutrients are either not synthesized in the body or not synthesised in required quantities and therefore must be obtained through diet.

The thirteen vitamins required by human metabolism are:  
Vitamin A (all-trans-retinol)
Vitamin B1 (thiamine),
Vitamin B2 (riboflavin),
Vitamin B3 (niacin),
Vitamin B5 (pantothenic acid),
Vitamin B6 (pyridoxine),
Vitamin B7 (biotin),
Vitamin B9 (folic acid), 
Vitamin B12 (cobalamins),
Vitamin C (ascorbic acid), 
Vitamin D (calciferols),
Vitamin E (tocopherols) and
Vitamin K (quinones).

Based on its solubility, vitamins are classified as either water-soluble or fat-soluble.
Vitamins A, D, E and K are fat-soluble
Vitamins B and C are water-soluble.

Vitamin A

Vision – Vitamin A is necessary for the formation of rhodopsin, the pigment in rod cells responsible for vision in dim light.        
Gene transcription – Vitamin A in retinoic acid form plays an important role in gene transcription.        
Haematopoiesis – Vitamin A deficiency results in the loss of blood stem cells responsible for production of blood cell components.
Immune function – Vitamin A plays an important role in T cell differentiation and proliferation.
Bone metabolism – Consumption of proper amounts of Vitamin A daily is proven to improve bone mineral density.
Skin health – Vitamin A is an anti-oxidant. It has an important role in regulating cell growth and development.

Vitamin A deficiency can be either primary or secondary. Primary deficiency occurs in adults and children who do not consume sufficient quantities of Vitamin A rich foods.  
Secondary Vitamin A deficiency is related to mal-absorption of Vitamin A, smoking and alcoholism.
Night blindness – impaired vision particularly in dim light
Xerophthalmia – medical condition where the eyes fail to produce tears
Xerosis – dryness of conjunctiva
Bitot’s spots – build up of keratin debris in the conjunctiva
Keratomalacia – eye disorder that involves drying and clouding of the cornea
Lowered immunity
Hyperkeratosis – abnormal thickening of the skin
Enamel hypoplasia – deficient enamel amount
