Sports Nutrition

Skeletal muscle mass is an integral body tissue playing key roles in strength and performance, both in sports and activities of daily living. However, inadequate intake of any of the essential nutrients will compromise health and physical performance.

Stimulating Muscle Protein Synthesis

The ingestion of small amounts of protein (about 20–25 g) closely before, during, and after exercising, has been attributed many benefits. Higher-protein diets have been shown to:

  • Promote gains in muscle mass, especially when paired with resistance training
  • Spare muscle mass loss during caloric restriction
  • Attenuate the natural loss of muscle mass that accompanies aging

Yeast products contain high-quality proteins, with all the essential amino acids, and have a high proportion of the branched chain amino acid (BCAA) leucine, a key amino in the stimulation of the muscle protein synthesis. Yeast extract in particular contains as much as 10.3 g of essential amino acid per 25 g of protein and 4.1 g of branched-chain amino acid per 25 g of protein, levels which are comparable to whey and casein extracts.

Vitamins and Minerals for Optimal Muscle Fitness and Performance

Routine exercise also increases the turnover and loss of many micronutrients from the body. Indeed, exercise was shown to increase the need for B-complex vitamins by as much as twice the current recommended amount. Adequate intake of B-vitamins ensures optimum energy production and the building and repair of muscle tissue.

Athletes who live at northern latitudes or who train primarily indoors throughout the year are at risk of Vitamin D deficiency. Vitamin D regulates the development and homeostasis of the nervous system and skeletal muscle.

Athletes, especially women, long distance runners, adolescents and vegetarians are at high risk for Iron deficiency. Oxygen carrying capacity is essential for endurance exercise as well as normal function of the nervous, behavioural and immune systems. Iron is required for the formation of oxygen-carrying proteins, haemoglobin and myoglobin, and for enzymes involved in energy production.

Athletes, particularly women, are at risk for Zinc deficiency, as Zinc plays a role in growth, building and repair of muscle tissue, energy production and immune status.

Athletes that compete in weight categories and body conscious sports such as wrestling, ballet, gymnastics, etc., have been reported to consume inadequate dietary Magnesium. Magnesium plays a variety of roles in cellular metabolism, and regulates membrane stability and neuromuscular, cardiovascular, immune and hormonal functions.

Athletes that are exposed to high oxidative stress or fail to meet dietary antioxidant requirements should consider supplementation. Antioxidant nutrients, such as Selenium and Glutathione, play important roles in protecting cell membranes from oxidative damage and in detoxication.

Bio availability of Yeast Micronutrients

Yeast's ability to incorporate certain vitamins and minerals within its cells makes it an ideal natural ingredient for dietary supplements formulated to help optimise muscle fitness and physical performance, especially muscular strength and power. Compared to pure forms of certain minerals and vitamins, those found in yeast have been shown in several studies to have slower absorption rates and higher bioavailability in animals and humans.

Lalmin® Vitality/Sport

This is a unique natural yeast-based (Saccharomyces cerevisiae) solution formulated with Lalmin® natural yeast-based ingredients that contain elevated levels of certain B-Complex Vitamins, Vitamin D, and Nucleotides. 500 mg of Lalmin® Vitality/Sports provides significant amounts of these highly bioavailable nutrients, which stimulate muscle protein synthesis; reduce tiredness and fatigue; help maintain the normal formation of red blood cells and cell division; protect cells from oxidative stress; and help maintain the normal functioning of the immune system and the nervous system.

Lalmin®

Other Lalmin® natural yeast-based ingredients contain elevated levels of key minerals and/or vitamins essential for optimal muscle fitness and physical performance, especially muscular strength and power.

These products include Lalmin® B-Complex, Lalmin® Vita D®, Lalmin® Se, Lalmin® Zn, Lalmin® Mg, and Lalmin® Fe.

Engevita® GSH

This is a primary grown natural yeast ingredient produced to have a naturally high level of glutathione, a substance with powerful antioxidant properties. Engevita® GSH yeast is also naturally rich in B-Complex Vitamins and contains high-quality protein.
