When it comes to minerals and vitamins, your body will require an optimal level of each type in
order to function efficiently. In fact, the vitamins are required to ensure that your body’s immune
system and digestive process are kept at their best so that you do not fall sick too easily. In most
cases, a full spectrum of vitamins would be available from your regular food intake to combat any
attacks and threats from bacteria and viruses. The following vitamins are necessary and needed by
• Vitamin A
• Vitamin Bs 1, 2, 3, 6 and 12
• Vitamin C
• Vitamin D
• Vitamin E
• Vitamin K
Do you need high volumes of vitamins and what are the side effects that could occur?
Naturally, anything that you take should be eaten in moderation and you should not incur over-
dosage of any vitamin because it would cause more harm than good. The bottom line here is to take
sufficient levels of each vitamin according to the standard recommended dosage daily. In fact, taking
multivitamin formulas like Usana Essentials would be the perfect option as your body will enjoy the
minimum required dosage of each vitamin.
Types of vitamins and side effects
Vitamin A – It has been found that Vitamin A is the most toxic among all the vitamins and this can be
very dangerous if you overdose on this. The normal recommended level of Vitamin A an adult should
take should be around 3,000 IU per day. Side effects of Vitamin A includes sweating, fatigue, and
restlessness while you could experience stomach or abdominal pains as well. On top of that, women
who are experiencing menopause could be at extreme danger if taking too much Vitamin A.
Vitamin B1 – This is known as Thiamine. Taking too much Vitamin B1 could experience side effects
like dizziness, headaches, nausea leading to vomiting and fatigue.
Vitamin B2 – This Vitamin B is known as Riboflavin. You should take only the recommended dosage
as the side effects include indigestion leading to diarrhoea as well as vomiting. Too much Vitamin B2
will turn urine into yellowish fluids.
Vitamin B3 – Known as Niacin, side effect of this vitamin could lead to heartburns, vomiting with
diarrhoea and fatigue.
Vitamin B6 – Vitamin B6 is known as Pantothenic Acid where it can cause breathing problems.
Besides that, overdose on this could cause losing coordination and headaches as well.
Vitamin B12 – Cyanocobalamin is the other name for Vitamin B12 and it can cause itchiness and
forming of blood clots while diarrhoea could occur as well.
Vitamin C – This is supposed to be the safest type of vitamins among all but taking too much could
lead to some severe conditions. This is because too much Vitamin C will naturally raise the level of
blood sugar which inevitably could cause serious conditions like diabetes.
Vitamin D – Taking too much Vitamin D will cause a spike in calcium levels. This would then cause
your arteries to harden which will result in kidney problems.
Vitamin E – Taking too much Vitamin E would increase your risk of cardiovascular diseases especially
if you have high levels of blood sugar and it can be a major risk if your body lacks Vitamin K.
Vitamin K – If you have problems like diabetes or kidney disease, taking too much Vitamin K could
worsen the treatment of your condition.

Dr Lyle MacWilliam is perhaps one of the most distinguished nutritionist around. He was a former
MP in Canada and has published his findings being one of the frontiers of research in biological
properties of antioxidants in heart cell membranes. In his book ‘Comparative Guide to Nutritional
Supplements’, he compared over 500 multivitamins and nutritionals in the market and presented a
neutral answer to the best and safest multivitamin product in the market.
