Vitamin Overdose Symptoms

Just say the word “vitamins” and you imagine a man or a woman energetic and athletic-looking usually in the latest sports gear jumping over hurdles at a race track. The influence of the advertising ingrained in our minds. Vitamins usually mean vitality, health, energy, vibrancy==-liveliness and a long, enjoyable disease-free life. Just holding that capsule in our hand, bringing it into our mouths and swallowing it, makes you feel that you’re doing something good for your mind and body even before the 30 minutes it needs to actually take effect. But as bad things happen to good people, even too much of a good thing is bad==-as we often forget when we are tempted, or even go pass temptation and take overdoses of our vitamins purposely.

As the following symptoms of vitamin overdose will tell you, taking mega doses of vitamins can have dire consequences. So think twice or better yet, consult your doctor or dietician before you increase your dose of vitamins.

The symptoms of overdose for the following vitamins are:

Nonetheless, it is most advisable to seek a doctor or dietician’s advice if you plan to increase your dose especially if you have high blood or diabetes.

The best advice is practical: read the label on the bottle and stay within the dosage advised. That’s what the label is for. Now that’s a good dose of common sense.
