Pharmaceutical drugs are regulated by the government authorities. Supplements are not.
Most supplements found in drug stores and pharmacies use cheap nutrients, which are poorly absorbed or not absorbed by our body at all. Also, the efficacy of the supplements, depend on their formula, which is often not the correct one. A lot of them also give incorrect information of dosage on their labels and the actual dosage does not match what’s in the pill.
Supplements is a very tricky area in the world of nutrition and while they become very important for some people (especially those who suffer from chronic diseases), they should not be taken mindlessly just because you feel they will meet your nutritional requirements.
Many supplements are full of additives, colors and allergens, and I already mentioned cheap quality nutrients, all of which counter the very reason why we take them in the first place!
As far as possible, meet your nutritional needs through REAL FOOD. Nothing can ever replace the nutrition you can get from nature. Stay away from anything that is made in factories, including supplements. Use supplements only when your diet is not sufficient in a particular nutrient, and use only the highest quality supplements, and those with the correct formula and dosage that you need for your health condition.
It would be worth doing some research on supplements, if you really believe in them and want to invest in your health.
Disclaimer – Before using any supplements on your own, pls consult your doctor for an opinion, especially if you have any medical issues or if you are pregnant.
