I think you'd be surprised to what extent the average South African 'supplements' without even knowing it. Odds are that if you eat certain maize and wheat meals, you're supplementing with vitamin A, thiamine, riboflavin, niacin, pyridoxine, folic acid, iron and zinc. This fortification is required by law. Then look at processed foods such as breakfast cereals and quick prep foods such as Futurelife. All fortified. Then take it one step further - how many of the animals that you eat haven't been supplemented with feed licks and blocks which are used to fortify, among other purposes, their diet. All this is often done with very good reason. Micronutrient deficiency is a big problem in SA and most of the world actually. [Edit: also, just because they're in your food, doesn't mean your body is absorbing the micronutrients. Many people have absorption issues due to disease, gastrointestinal surgery, gut issues, genetics, etc. In such cases eating fortified foods and additional supplementation is very helpful]
