Important cautions when taking vitamins

This calculator is for reference only; consult a medical professional for an accurate diagnosis. Vitamin supplements can have side effects when overconsumed. Whenever possible, get vitamins from natural foods. If you have a specific condition or take medication, consult a doctor before supplementing. Pregnant or breastfeeding women may have different recommended amounts. Fat-soluble vitamins (A, D, E, K) accumulate in the body and can be toxic in excess, so take particular care.

03

Recommended amounts by age, gender and lifestyle

Recommended dietary allowances (RDA) for vitamins vary by age, gender and lifestyle. Teenagers (14-18), adults (19-64) and seniors (65+) have different needs for some vitamins. Active people may need about 20% more, and smokers are advised 35% more vitamin C due to higher oxidative stress. Pregnant women need about 30% more of several vitamins, including folate. This calculator factors in these elements to suggest personalized amounts.

Do I have to take vitamin supplements?
With a balanced diet, you can get most vitamins from natural foods. Use supplements as a backup when deficient, and be careful not to overconsume fat-soluble vitamins.
Why do smokers need more vitamin C?
Smoking raises oxidative stress in the body and increases vitamin C consumption, so smokers are advised about 35% more vitamin C than the standard amount.
