While having a diet rich in fresh fruit and veggies is definitely a great start, due to soil degradation, pollution and different farming methods, coupled with having to consume copious amounts of one particular vegetable in order to get the daily mineral intake, supplements make it easier to ensure that you're getting enough of the right vitamins and minerals regularly.
Vitamin C, Magnesium and MSM (Organic Sulphur) are all great supplements to take regularly in general. They have so many far-reaching benefits for a myriad of health conditions and contribute to some serious vital bodily functions. (Studies have shown that sadly the majority of society are deficient in Magnesium, so this mineral is something you should definitely consider)
In addition to general well-being, supplements can also contribute to more specific conditions like your skin health for example.
If you suffer from problem skins like Acne, Rosacea, Eczema or even dry skin, Vitamin A in the form of Cod Liver Oil or Beta Carotene can help supply Vitamin A and promote the pathway of sebum (oil) through the body without blockages, a great help with skin problems. (It's almost like having a treatment from the inside out!)
Essential Fatty Acids (Omega's) are also great for skin health and problematic skins. A high quality fish oil supplement will do wonders, if you find you're not able to eat deep sea fish 3 times a week.
Whether it's energy your lacking, problematic skins, or you're just looking to improve your general well-being it is worth speaking to a Naturopath, even your GP to get an idea of what supplements you could start incorporating into your every day routine to help your body to function at its optimum.
