Professional Nutritional Supplements are used very commonly in Holistic Nutritional Treatments in conjunction with personalized diets and lifestyle change. These are very different from Over the counter supplements available at the stores. These can be prescribed only by Licensed Healthcare practitioners such as me. They are used under clinical settings for people with chronic health conditions so they are of highest standards devoid of any harmful substances. Targeted nutrients and herbs are used for formulating these and they undergo very strict safety testings to ensure bioavailability, purity and potency.
