Can too much vitamins harm the body ?

Absolutely Yes. Vitamins can cause harm.

Vitamins are very essential for life.

But too much of vitamins is bad.

You can buy paracetamol in a supermarket and it (rightly) comes with a big list of side effects .

You can freely buy various vitamins and supplements in supermarkets and none of them come with any warning what so ever.

Because vitamins are heavily promoted over Social media, newspapers, TV, and internet, many people think vitamins are safe and good. So people overindulge hoping for more benefits. But taking too much of vitamins is risky and can cause health problems due to Hypervitaminosis.

A recent article in Guardian points out the risks from taking too much of vitamin supplements. A man took too much of vitamin B6 and this resulted in damage to his nerves!

So be very careful with extra vitamins and supplements. Check whether you need the supplements at all. Try natural products rather than factory produced artificial supplements.

Benefits of Vitamin D supplements and Omega 3 supplements

Most people assume that nutritional supplements are always beneficial. But it is not always the case.

Paradoxically, the people, who may need the supplements because they don’t have a healthy diet, are the often ones who do not take the supplements !

But people, who usually do not need various supplements, because they are health conscious and have a good healthy diet, are often the ones who take the supplements unnecessarily !

Sometimes Supplements can be harmful. Hence, the need for clinical trials to assess the benefits and risks of various supplements.

So it is interesting to read a trial in the British Medical Journal (BMJ) which looked at Vitamin D and marine derived omega 3 fatty acids supplements. The study looked the effect of these two supplements in preventing Autoimmune diseases.

Autoimmune disease is a type of disease where body’s own immune system misfires and causes inflammation in self-tissues.

Autoimmune diseases, are often chronic conditions and cause considerable misery.

The study published in BMJ looked at Autoimmune diseases, such as rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease, psoriasis, and inflammatory bowel disease, and all other new onset autoimmune diseases.

This well conducted study used a dummy pill and hence the results are usually expected to be quite reliable.

About 25 800 participants were enrolled in the study and were followed up for an average of about 5 years.

This large study from United States found that vitamin D and omega 3 fatty acid supplementation taken for five years reduces the risk of developing autoimmune diseases.

Can vitamins increase risk of cancer ?

Yes

Vitamins are absolutely essential nutrients and vitamin deficiency causes various illness.

But a high dose of vitamin, far too much than needed by the body, is also bad.

Everything in moderation is good. Even an abundance of a good thing is bad.

It is similar to food. Lack of food would cause starvation and even death in the extreme. But too much of food causes obesity and other health problems. Same principle applies to vitamins.

A Cochrane review looked at the ability of vitamins to prevent lung cancer. The review concluded that there is “no beneficial effect of supplements for the prevention of lung cancer and lung cancer mortality in healthy people”

Worryingly, the review also found that the following:

Vitamin A supplements increase lung cancer incidence and mortality in smokers or persons exposed to asbestos”.

Vitamin C increases lung cancer incidence in women.

Vitamin E increases the risk of haemorrhagic strokes.

So if you are having a healthy balanced diet, be careful with vitamin supplements.

Yes, Dietary supplements can be harmful.

Vitamins and Minerals are absolutely essential nutrients for a Healthy body and a Healthy mind. Anyone not eating a healthy balanced should look what nutrients they might be missing.

But on the other hand, taking too much of vitamins and minerals, when they are not needed, could be harmful to the body.

There is widespread use of dietary supplements during cancer treatment, in the hope they can reduce side effects but many do not think about the disadvantages.

An American study of Breast cancer patients undergoing Chemotherapy looked at the effect of taking dietary supplements such as anti-oxidants, iron, vitamin B12, and omega-3 fatty acids.

Breast cancer patients who took the dietary supplements during chemotherapy were found be harmed by them. They had a higher chance of cancer coming back compared to people who did not take these supplements. The supplements also increased risk of death in those the supplements.

Beware supplements when used improperly, can be harmful.

Vitamin D reduces risk of advanced cancer in normal-weight individuals.

“An ounce of prevention better than a pound of cure” is certainly true when it comes to cancer prevention.

Vitamin D, the “sunshine” vitamin has been proven to reduce risk of advanced cancers an large American study.

The study presented at the ASCO ( American Society of Clinical Oncology) virtual scientific symposium in 2020,

“The VITamin D and OmegA-3 TriaL (VITAL) was a high quality study. The study randomly assigned patients to Vitamin D3 supplements and/or omega-3 fatty acid supplements and/or both or placebo in 25,871 men and women.

The study found that “vitamin D supplementation decreased risk of developing advanced cancers by 17% compared with placebo ”

“Omega-3 supplementation did not reduce the incidence of advanced cancer.”
