Our Lalmin® B-Complex Vitamins is an inactivated dried whole cell yeast (Saccharomyces cerevisiae) containing elevated levels of B-complex vitamins. A 500-mg quantity provides 100% of the recommended daily allowance (RDA) for B-complex vitamins. The natural yeast fermentation is supplemented with low levels of B-complex vitamins, the yeast cream is pasteurized and then spray dried or roller-dried/grinded. This process allows the vitamins to interact with the yeast cell components and the gentle processing conditions then preserve the level of the vitamins, minerals and other micronutrients. Due to the high potency of Lalmin® B-Complex Vitamins, it is suitable for tableting and capsules.


Saccharomyces cerevisiae is known as being a natural rich source of B-complex vitamins. However, it is very difficult to guarantee constant levels of B-complex vitamins in brewer’s by-products and even baker’s yeast. In our Vitamin Yeast, the natural yeast fermentation is supplemented with known levels of B-complex vitamins and therefore we can guarantee that this product contains always the same amount of each vitamin.

As the use of nutritional supplements increases, there is a growing consumer demand for more sophisticated information on the products they are consuming. Some of the questions on vitamin yeast concern the importance of B-complex vitamins in the diet, the bioavailability of organic vitamin yeast versus inorganic sources and toxicity issues. We hope that this information will be useful to those considering using vitamin supplements. We feel that Lalmin® B-Complex Vitamins is a natural, convenient, safe and economical way to increase B-complex vitamins intake.


Vitamins are organic compounds needed in small quantities to promote growth, life and reproduction capabilities for both humans and animals. Whereas plants, humans and animals are not able to synthesize vitamins, they have to be part of the diet. Our Vitamin Yeast is enriched with eight essential hydrosoluble B-complex vitamins, which are Thiamin (B1), Riboflavin (B2), Pyridoxine (B6), Niacin (B3), Pantothenic acid (B5), Folic acid (B9), Biotin (B8) and Cobalamin (B12)


The principal metabolic function of thiamin is as the precursor for thiamin diphosphate, which is the coenzyme for a number of reactions involved in carbohydrate metabolism and central energy-yielding metabolic pathways, thus thiamin is involved in cellular energy production.


Riboflavin is the precursor for the synthesis of two coenzymes, riboflavin phosphate and flavin adenine dinucleotide (FAD). These two function in a variety of enzymes catalysing oxidation and reduction reactions and electron transport. Riboflavin is thus involved in a wide variety of metabolic pathways, including the biosynthesis and catabolism of amino acids, fatty acids and carbohydrates.


Six different chemical forms of vitamin B6 occur in foods: pyridoxine, pyridoxal, pyridoxamine and their phosphates. After absorption these forms are involved in about 60 enzymatic systems.


Two related compounds, nicotinic acid and nicotinamide, have the biological activity of niacin. Nicotinamide can be synthesized from the essential amino acid tryptophan. Requirements for tryptophan and niacin must therefore be considered together. The metabolic function of niacin is as the precursor of the nicotinamide nucleotide coenzymes, NAD (nicotinamide adenine dinucleotide) and NADP (nicotinamide adenine dinucleotide phosphate), which are involved in a wide variety of oxidation and reduction reactions.


Pantothenic acid has a central role in a wide variety of metabolic pathways. It is required for the synthesis of coenzyme A (CoA), which is required in the metabolism of carbohydrates, amino acids, and fatty acids. It also plays an important role in the synthesis of the sterols like cholesterol. Pantothenic acid is essential for the synthesis of acetylcholine, which is a chemical mediator of nervous communication.



After absorption, the various forms of folic acid are transformed into several active coenzymes. Their principal function is to serve for the transport of single carbon units (purin and pyrimidin) essential for DNA and RNA biosynthesis and methylation reactions. This function explains the reason why folate is very important in cellular division and reproduction.


Biotin functions as the coenzyme transferring carbon dioxide in four reactions: pyruvate carboxylase, a key step in gluconeogenesis; acetylCoA carboxylase, the first step of fatty acid synthesis; and in two other important carboxylases. Intestinal bacteria synthesize relatively large amounts of biotin, and it is assumed that his contributes to the host’s nutrition.


Vitamin B12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid synthesis and energy production. It is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis.
