Can vitamin supplements cause dependency? Will I go through withdrawals if I stop taking them?
Aside from the possibility of inadequate nutrient intake from the diet, no side-effects are associated with discontinuation of supplements.
Why do I need nutritional supplements?
One question that commonly arises is, “if I eat a healthy diet, do I still need to take supplements?” Let it be clearly stated that a healthy diet is a necessary foundation for any program of optimal nutrition, and there is no substitute for eating well. In this context, nutritional supplements are designed to complement a healthy diet, not replace it. Supplements should be designed to provide advanced levels of vitamins, minerals, and antioxidants – many that are difficult to obtain from diet.
How do I determine which products are right for me?
Each human being has a unique health profile and unique nutritional needs. Part of a lifelong program of good nutrition is recognizing that everyone has specific nutritional needs, and those needs may change as individuals move from one stage of life to the next. For each person, a unique combination of age, sex, lifestyle, and other considerations requires a nutritional program that is both flexible and customized.
Does a person who weighs more need to take more supplements?
According to the most recently published Dietary Reference Intakes by the Institute of Medicine and the National Academy of Sciences (2004), there is currently scientific agreement that nutrient needs vary significantly with age, but are not strongly dependent on body weight or body composition.
Can I take more than one Vitamin D tablet per day?
It is recommend that you follow the suggested serving size and other applicable directions as they are listed on product labels. If you feel that you require higher amounts of vitamin D, please consult with your health care professional.
What is glycemic index?
The glycemic index (GI) is a way of measuring the rate at which carbohydrates are broken down and appear in the blood as simple sugars. In general, the more refined and processed the food, the faster the food is broken down and the higher the GI.
High GI foods act rapidly to influence blood sugar, providing quick energy. However, this energy is usually short lived and hunger soon returns, potentially leading to overeating and weight gain.
Low GI foods affect blood sugar more slowly and steadily. These foods provide greater satiety and longer lasting, more consistent energy, making eating less (and maintaining weight) easier.
Are liquids better than tablets?
A well-made tablet provides a very effective delivery system and is the chosen form of most pharmaceutical medications. This is because tablets have been confirmed, through years of carefully controlled studies, as a reliable and efficient delivery system for medications. Why would vitamin and mineral supplements be any different? Does anyone doubt that an aspirin tablet is ineffective because it comes in a tablet?
When you ingest a supplement in either liquid or tablet form, it must first pass through the stomach before reaching the small intestine. If liquids were simply absorbed directly into the bloodstream, as some supplement companies sometimes claim, what would happen when individuals consumed soup? Would it also be absorbed directly into the bloodstream?
