In same specific cases, use of vitamins and minerals supplements  should be considered, however medical doctor recommendation should be sought in most cases.  The following condition may merit supplementation:

• Women who bleed excessively during menstrual period  may need more iron.
• Pregnant or lactating women may need extra iron, calcium,  and the vitamin folate.
• People with low energy intake(1200 kcalories or less) need a range of vitamin or minerals. This include elderly people  who perform little physical activity.
• Same vegetarian  may need extra calcium, iron, zinc,  and vitamin B12 (B12 is found in appreciable amount  only in animal products).
• Newborns  under the directions of a physician, need a single dose of vitamin K to last until diet  and synthesis of bacteria suffice.
• People of specific illnesses or diseases and those on certain medications may need supplementation of specific vitamins and minerals under direction of a physician.

Touting nutriments as a cure for many diseases is quackery.

Are natural vitamins superior to the synthetic vitamins superior? NO. The body cannot tell the difference, the only difference is PRICE.

The process of science applied nutrition. Only after careful and thorough analysis does a research finding deserve to influence  our food choices.

Pharmacy  typically carry hundreds of supplements, many are  completely useless, they seems to profit from public confusion.
