Good nutrition can have a powerful impact on your health, whether you are recovering from disease or simply trying to lose weight. Ideally, you should get all the vitamins, minerals, and other nutrients you need from the food you eat, but this is not always realistic. A nutritional supplement such as Sustagen can help to ensure that you are well nourished.

What Is Sustagen?

Sustagen is a nutritional supplement primarily marketed in Australia and New Zealand. It is available in the United States under the name Boost. Consumer formulas are designed to help busy families and individuals ensure that they get the nutrition they need even if their meals are less than optimal. The hospital formula is a nutritionally complete meal replacement designed for patients who are recovering from disease and suffering from poor appetite.


The nutrients your body needs can be divided into two categories: macronutrients and micronutrients. Macronutrients are carbohydrates, protein and fiber. These are substances your body needs in large quantities. Micronutrients are substances such as iodine, iron, and vitamin A, which your body needs in very small quantities. These micronutrients are essential to good heath, and deficiencies in micronutrients can cause serious impairments. Iodine deficiency, for example, causes mental impairments and can lead to miscarriage, birth defects and irreversible mental retardation.

Weight Gain

In some cases, weight loss can make it difficult to recover from disease or maintain good health. Women in early stages of pregnancy, for example, often suffer from nausea and low appetite. Lack of appetite can cause a pregnant woman to skip meals or eat less than she normally would, leading to weight loss and nutritional deficiencies that could harm both the mother and baby.

Weight Loss

Overweight and obesity are often caused by malnutrition. Overweight and obese individuals often eat sufficient quantities of food, but that food is nutritionally sparse. Nutritional drinks such as Sustagen can help overweight individuals lose weight by replacing low-nutrient meals.

Allergens and Special Diets

Sustagen is a milk-based product, so if you are lactose intolerant you should add lactase drops to your beverage to counteract the lactose. Sustagen is gluten-free and suitable for Lacto- and Lacto-ovo vegetarians. Since it is milk-based, it is not suitable for those following a vegan diet. There are no nuts in Sustagen, but they are present at the manufacturing site of Sustagen ready-to-drink products. Sustagen powders are nut-free.
