Supports Nervous System Health & Energy Metabolism*
PRODUCT DISCUSSION
PhysioLogics B-Complex Sublingual Liquid is a multifunctional blend of important
B Vitamins, including B-2, B-6, B- 12, Niacin, and Pantothenic Acid. B Vitamins
are essential for normal formation of blood cells, and also support a healthy
nervous system, energy metabolism, and vision health.* The body requires a daily
source of B Vitamins because B Vitamins are water-soluble.
Acid reflux/heartburn medications (proton pump inhibitors) may decrease Vitamin B-12 absorption from the digestive tract. Therefore it can be important to supplement with Vitamin B-12 when using these medications. Note: Vitamin B-12 supplements are not intended to serve as a replacement for Acid Reflux Medications, nor should patients discontinue prescribed medications while supplementing with Vitamin B-12.
STRUCTURE AND FUNCTION
Riboflavin (B-2) assists in oxidation/reduction reactions, including those
involved in energy pathways and the metabolism of carbohydrates, fats and
proteins.* It is also significant for the maintenance of the skin and mucous
membranes, the cornea of the eye, and nerve sheaths.*
Niacin (B-3), also known as nicotinic acid and nicotinamide, serves as a coenzyme in oxidation/reduction reactions as nicotinamide adenine dinucleotide (NAD) and its phosphate form (NADP). NAD functions in intracellular respiration and oxidation of glyceraldehydes, lactate, alcohol, and other fuel molecules. NADP is required in reductive biosyntheses, such as fatty acid and steroid synthesis. Niacin is needed for the metabolism of food, maintenance of healthy skin and nerve cells, DNA replication and repair, and cell differentiation.*
The major coenzyme forms of Vitamin B-6, Pyridoxine (B- 6), pyridoxal 5'-phosphate (PLP) and pyridoxamine (PMP), function in the catabolism of carbohydrates, proteins and fats. PLP serves as a coenzyme for more than 100 enzymes involved in amino acid metabolism, including aminotransferases, decarboxylases, and dehydratases. Vitamin B-6 is also used in the production of red blood cells, and is involved in the single-carbon cycle, which produces methyl groups used in the synthesis of other compounds. Vitamin B-12 (Cobalamin) is a coenzyme in the single-carbon cycle, and, with Vitamin B-6 and Folate, converts homocysteine to methionine. Vitamin B-12 is also required for maintenance of nerve sheaths, normal blood formation, and DNA synthesis and repair.*
Pantothenic acid is used for the synthesis of coenzyme A and thus is involved in many metabolic pathways, including energy metabolism; catabolism of carbohydrates, lipids, amino acids; and synthesis of hormones and neurotransmitters.*
CLINICAL EVIDENCE
- A review in the Journal of the American Medical Association stated that most people do not consume optimal amounts of vitamins by diet alone. In fact, suboptimal intake of some vitamins, even above levels classified as deficiency, may be unhealthy and is common in the general population. The reviewers concluded that it is wise for all adults to take vitamin supplements. (Fairfield and Fletcher, 2002)
- The Oxford Healthy Aging Projects, a cohort study conducted from 1993 to 2003, examined the relationship between serum vitamin B-12 status and cognitive function in older adults. A significant association was found between low levels of vitamin B-12 and the incidence and rate of cognitive decline over the ten year period. (Clarke et al, 2007)
SUMMARY
The B Vitamins work individually and synergistically in a wide array of
biological functions to maintain health.* PhysioLogics B-Complex Sublingual
Liquid provides a convenient, easy-to-use, liquid form of high-potency B-
Complex vitamins.
SUGGESTED DOSAGE
SHAKE WELL before use. For adults, place one full dropper (1 mL) under the
tongue and hold for 30 seconds before swallowing, or follow the advice of a
health care professional.
