Vitamins – The adverse effects

Like millions of people, I take multivitamins and minerals in the form of a suppliment tablet. They’re freely available over the counter, constantly advertised on TV, radio and print, and people tend to says “make sure you’re getting enough vitamins and minerals” whenever you don’t feel your best as it has been drummed into them in childhood.

So it seems harmless not to adopt the mindset that one may as well use a suppliment to fill any gaps missing in my diet, take preventative measures against the common cold, boost your immune system, live a vitamin-rich diet.

Vitamins are organic compounds needed by the body for essential metabolic reactions. Lack of vitamins can cause mild to serious effects.

However, people who are generally healthy and take in enough vitamins in their diet do not need high doses of oral vitamins in form of pills or syrups. These pills or syrups are especially designed for people who have any vitamin deficiency and they have been recommended these supplements by their physician. Excessive and unnecessary use of vitamins can cause some adverse effects as not every vitamin may be good for your body.

It is the fat soluble vitamins that are likely to produce some pathological changes when given in large quantities.

Moreover, many vitamin pills are devious in their dosages. Many vitamin C pills for example, contain in excess of 4 times the RDI (Recommended Daily Intake). This can lead to oxalate kidney stones if taken in large quantities. Also, high doses of ascorbic acid could increase the acidity in urine that can precipitate the myeloma protein and damage kidneys.

Also, large amounts of vitamin C should be avoided as it may cause Osteoarthritis, the breakdown of cartilage in joints. It’s a worry so much vitamin C is sold so flippantly, in such high quantities in every supermarket.

Practically every time you buy a bottle of “sport”, “flavoured” or “energy water”, you’re intaking vitamin B which adds up at alarming rates. Excess of vitamin B (Thiamine) produces a shock-like state and anaphylactic-type (hypersentitivity) sensitization when it is injected in the body. Also use of Nicotinic acid, a kind of vitamin B is a fairly potent vasodilator and leads to dilation of blood vessels. Other forms of vitamin B have other adverse effects, which you can read more about here:

People make enough vitamin D in their body from spending 20 minutes in the sun. Excessive use of vitamin D has been known to cause hypercalcemia (too much calcium in the blood) with metastatic calcification in the kidney and blood vessels, also risking calcification of the heart. Use of vitamin D2 should be done very carefully as it can lead to complications.

If large doses of vitamin K are taken, it can cause break down of red blood cells also known as Hemolytic anemia as well as jaundice.

If phytonadione, a form of vitamin K is injected it can cause severe adverse effects like such as cardiac irregularities, chest pain, cyanosis, decreased level of consciousness, circulatory collapse, rapid weak pulse, hypotension and cardiac or respiratory arrest.

In general, if vitamins are taken in large quantities, it results in a condition called Hypervitaminosis, literally “Too many vitamins”.

Living in this state may cause changes in bone or skeletal development, hepatomegaly (an enlarged liver), anemia, loss of hair, and related other symptoms.

Think twice before you pop more pills. Even if they come from the healthy section of your supermarket.

    My physiology and pathology lecturers both told me that all vitamin tablets do is create expensive piss. Some people might need a vitamin supplement sometimes in some rare circumstances but the vast majority of people have no need for them if they eat a good diet.

    Vitamin overload as we in Pharmacy call it is becoming more and more of a problem for the consumers out there. As my role in Pharmacy is directly associated with the nutrition side of thingsas well as a Diabetic educator ,Supermarkets are a breeding ground for serious problems in the community. All some consumers of vitamins are interested in is the PRICE. The shelves are full of toxic and serious side effects.Who has ever gone into a Coles,Woolies, Franklins and Aldi etc and been given a full explanation and a one on one consultation about the vitamins they are about to consume on a daily basis, it dosent happen. I was horrified one day to hear a person packing the shelves of my local supermarket say to a customer Oh that Vitamin works really well a lot of people buy it and my Aunty thinks its great. Vitamins can help and restore levels in people who have found to be deficiant especially in the elderly, recovering from serious long term illness or when a blood test has shown low levels of certain vitamins. But in general nothing beats a good balanced diet,exercise and a healthy mind set. To often Vitamin companies are also to blame with the saturation of their advertising campaigns directly targeting the consumers telling them they need the vitamins and lets face it, if its in BODY AND SOUL or the WOMANS WEEKLY or A CURRENT AFFAIR we must have and need it. Andrews writing of the article was very well put together and researched. Chez,Sydney
