• Overview
• Valine is one of three branched-chain amino acids (BCAAs) Health Benefits of Valine Metabolism Valine may help to correct negative Hydrogen balance within the body. Anecdotal Evidence Musculoskeletal System Valine is often used (by bodybuilders) in conjunction with other Branched Chain Amino Acids (BCAAs) to stimulate Muscle Growth . Anecdotal Evidence Nervous System Valine (6,400 mg per day), when supplemented in conjunction with other Branched-Chain Amino Acids, may improve muscular strength and the ability to walk in Amyotrophic Lateral Sclerosis (ALS) patients: Anecdotal Evidence Valine levels are often severely depleted in the blood and Cerebrospinal Fluid (CSF) of ALS patients. Valine is a component of the Myelin Sheath s of Neurons. Supplemental Valine may help to alleviate Nervousness . [1] Valine may Enhance the Function of these Substances Amino Acids Glutamine can be manufactured endogenously within the body from Valine. Carbohydrates Valine can be metabolized to form Succinic Acid within the Liver after it has lost its amino group by transamination. These Substances May Enhance the Function of Valine Hormones Glucagon catalyzes the conversion of "spent" Valine to form endogenous Glucose. Dietary Sources of Valine (mg of Valine per 100 grams) Algae: Chlorella Animal Supplements: Velvet Deer Antler Cereal Grains: Brown Rice 177 White Rice 140 Dairy Products: Cottage Cheese 951 Milk - Cow's 249 Yogurt 255 Eggs: 940 Fruit: Bananas 47 Strawberries 23 Peach 40 Fungi: Mushrooms Herbs: Passion Flower Legumes: Soya Beans 638 Butter Beans 1,030 Lentils 626 Chick Peas 1,004 Meat: Lamb 1,273 Chicken 1,061 Beef 1,167 Liver 1,255 Nuts: Almonds 1,124 Brazil Nuts 822 Peanuts 1,506 Cashew Nuts Walnuts 974 Seafood: Trout 1,530 Cod 1,018 Prawns 960 Seeds: Sesame Seeds 837 Pumpkin Seeds 1,566 Vegetables: Fennel Garlic Potato 138 Tomato 31 Valine May Interfere with These Substances Amino Acids Valine may compete with Tyrosine for absorption into the body. Valine may inhibit the ability of Tryptophan to cross the Blood-Brain Barrier; it competes with Tryptophan for entry into the Brain. [2] Dosage Recommendations RDAs The RDA for Valine (based on a survey of 48 persons published in 1979) is 375 - 800 mg per day. The amount of Valine required by a person weighing 75 kg according to the U.S. National Academy of Sciences is 1,050 mg daily. It equates to 14 mg of Valine per kg of body weight per day. Therapeutic Dosages The supplemental therapeutic dosage of Valine (with other Branched-Chain Amino Acids) used in a clinical trial that found beneficial effects in Amyotrophic Lateral Sclerosis (ALS) patients was 6,400 mg per day. Average Human Intake The average consumption of Valine from dietary sources by non-vegetarians in the USA is 7,100 mg daily. The average consumption of Valine from dietary sources by lacto-vegetarians in the USA is 5,600 mg daily. The average consumption of Valine from dietary sources by vegetarians in the USA is 4,300 mg daily. Bioavailability Valine competes with other Amino Acids - Large Neutral (LNAAs) for transportation across the body's Blood-Brain Barrier . Availability of Valine Supplements Valine Supplements Supplemental Valine is available in the form of: 500 mg capsules loose L-Valine powder Formulas Valine is an ingredient in Amino Acids - Branched Chain (BCAAs) supplements.
