Vit B1About Vit B1
Physiological functions: Thiamine pyrophosphate is a coenzyme and the active form of vitamin B. It functions as coenzyme in decarboxylation of a-keto acid and in Hexose Monophosphate shunt.
Deficiency symptoms: In severe vitamin B1 deficiency beriberi develops. It is of two types:
a) Wet beriberi
b) Dry beriberi
Wet beriberi: In this the symptoms are related to the cardiovascular system and they are palpitations, tachycardia, dyspnoea, ECG changes, oedema, and high output cardiac failure.
Dry beriberi: The symptoms and signs are related to the Nervous system. The main features are peripheral neuritis, hyperaesthesia (localized areas) or anaesthesia, there is gradual loss in muscle strength, wrist drop, poor memory, depression, lack of initiative and anorexia.Mechanism of Action of Vit B1Thiamine exerts it`s action by influencing carbohydrate metabolism. It combines with ATP to form thiamine pyrophosphate in the body. Thiamine pyrophosphate acts as a coenzyme for carbohydrate metabolism, decarboxylation of ketoacids, and hexose monophosphate shunt. It also have plays some role in neuromuscular transmission.Pharmacokinets of Vit B1Absorption: Well absorbed orally.
Distribution: Widely distributed in the body. It is also distributed in to breast milk.
Metabolism: Metabolized in the liver.
Excretion: Excess thiamine is excreted through urine.

Vit B2About Vit B2N/AMechanism of Action of Vit B2Riboflavin exerts it`s action by influencing metabolic reactions. Riboflavin functions in the forms of flavin adenine dinucleotide (FAD), and flavin mononucleotide (FMN) which are coenzymes for flavoproteins involved in many oxidation-reduction reactions. Both FMN and FAD play a vital metabolic role in numerous tissue respiration systems. Riboflavin also directly involves in maintaining erythrocyte integrity.Pharmacokinets of Vit B2Absorption: Well absorbed orally; bioavailability increases when administer along with food.

LysineAbout LysineNutrient, an a-amino acid, Essential amino acid.
Mechanism of Action of LysineLysine is an essential amino acid. It is a basic building block of protein. It is required for tissue repair, growth and bone development in children, help in calcium absorption and maintaining the correct nitrogen balance in the body and maintaining lean body mass. It produces antibodies, hormones, enzymes, collagen formation.
Since it helps with the building of muscle protein, it is useful for patients recovering from injuries and recovery after operations. It is also useful against herpes and cold sores.
The single supplement should be taken on an empty stomach because larger amounts of the amino acid can build up in the blood and brain.
