What is L-Valine used for?

L-Valine is one of 20 essential amino acids required by the human body to function properly. It is an aliphatic amino acid, which means it has straight-chain carbon atoms in its backbone. It is classified as a branched chain amino acid (BCAA) due to the presence of branched side chains in its molecular structure.

L-Valine is considered an essential amino acid because the body cannot synthesize it on its own and must obtain it through diet. It is found in a variety of protein-rich foods, including meat, fish, dairy products, beans and legumes. L-Valine is involved in many important physiological processes, including protein synthesis and regulation of blood sugar levels. It is also involved in the metabolism of other branched-chain amino acids and has been shown to play a role in the growth and repair of muscle tissue.

Recommended Daily Intake (RDI) of L-Valine

The recommended daily intake (RDI) of L-valine depends on a variety of factors, including age, gender, and overall health status.

Adequate intake (AI) levels of L-valine are estimated average daily intakes sufficient to meet the nutritional requirements of nearly all healthy individuals of a given life stage and sex group. L-valine AI levels for different age groups and genders are:

  • Infants: The recommended intake of L-valine for infants is approximately 31 mg per kilogram of body weight per day. For example, a 6-month-old baby weighing 7.5 kg (16.5 lb) needs approximately 232.5 mg of L-valine per day

  • Children 1-3 years old : Recommended intake of L-valine for children varies by age and gender. For children aged 1-3 years, the recommended daily intake is approximately 34 mg per kilogram of body weight per day. For children aged 4-8 years, the recommended daily intake is approximately 22 mg per kilogram of body weight per day.

  • Adolescents and Adults : The recommended daily intake of L-valine for adults is approximately 26 mg per kilogram of body weight per day. For example, an adult weighing 70 kilograms (154 pounds) needs approximately 1820 milligrams of L-valine per day.

  • Pregnant women : The recommended daily intake of L-valine for pregnant women is slightly higher than that for non-pregnant adults, about 28 mg per kilogram of body weight per day. For example, a pregnant woman weighing 70 kg (154 lbs) needs approximately 1960 mg of L-valine per day.

It's important to note that these are general recommendations only and individual needs may vary based on factors such as activity level, health, and overall diet. It's always a good idea to consult a health care professional to determine your specific dietary needs.

What are the main benefits of L-Valine in animals?

This amino acid is essential for animals, just like it is for humans. It is important for the health and growth of animals. Here are some of the main benefits of L-valine for animals:
