  • Supports blood-forming processes and reduces the risk of anemia
  • Helps to maintain proper energy level in the organism

Seeking Health B Complex Plus is an advanced dietary supplement containing carefully selected, highly bioavailable forms of B-group vitamins.

In the composition of the preparation there are bioactive forms of folate

(L-5-MTHF), vitamin B12 (methylcobalamin, adenosylcobalamin), riboflavins (riboflavin-5′-phosphate sodium) and vitamin B6 (P-5-P, pyridoxal 5′-phosphate). In this complex there are also thiamin, niacin, biotin and pantothenic acid as well as choline and Shilajit extract (improving the assimilability of the preparation).

The preparation helps to maintain proper homocysteine level, thanks to which it decreases the risk of circulatory diseases, supports the work of the brain as well as adds energy and improves memory, concentration and well-being.

B-group vitamins are organic compounds of varied structure, soluble in water, which are responsible for the proper course of many key processes in the organism. They play the function of i.a. catalysts of biochemical reactions and support efficient functioning of the nervous system and cardiovascular system.

Folate reduces homocysteine level, takes part in the production of neurotransmitters and influences proper metabolism of amino acids. Deficiency of this vitamin may result in erythrocyte shortage (which may lead to megaloblastic anemia), increased homocysteine level, DNA synthesis disorders, nervous system dysfunction and severe fetus disorders – neural tube defect.

Vitamin B12 (cobalamin) takes part in blood-forming processes (participates in the synthesis of red cells), is essential for the production of DNA and RNA in erythroblasts, influences the work of the nervous system (takes part in building myelin sheath and the production of neurotransmitters) and regulates many metabolic processes, thanks to its role of enzyme cofactor. Its deficiency, among others, increases organism’s susceptibility to circulatory diseases and disturbs the activity of the nervous system.

Vitamin B6 (pyridoxin) plays the role of a cofactor in more than 140 enzymatic reactions, which are related mainly to the synthesis and breakdown of amino acids. Vitamin B6 improves cognitive functions (takes part in the production of serotonin and dopamine), supports the immune system (participates in the synthesis of antibodies) and also is responsible for maintaining proper energy level in the organism. Vitamin B6 deficiency may be the cause of anemia, depression, disorientation and weakening of the immune system. 

Vitamin B2 (riboflavin) supports the work of mitochondria (influences chain transport of electrons), regulates metabolism of protein, fat and carbohydrates, takes part in the synthesis of oxidoreduction enzymes and is responsible for the proper thyroid function. Its deficit may give the symptoms of inflammations of oral cavity, throat and lip corners.  

Vitamin B and methylation
Methylation is a process enabling among others proper cell division, DNA repair, proper work of the immune system, neutralization of toxins. This process consists in passing methyl group between molecules and then attaching it to an enzyme, which is responsible for a given biological function.

It is assumed that problems with methylation, especially those regarding MTHFR gene mutation may concern even every second person. As a consequence, they may lead primarily to the increase of homocysteine level contributing to intensifying inflammation and the development of circulatory system diseases, disorders in neurotransmitter synthesis and dysfunction of detoxification processes in the organism.

Folate, vitamin B2, vitamin B6 and B12 are especially vital in the proper course of methylation. Their deficiency inhibits the course of this process and supplementation helps to regulate the process of methylation and release of neurotransmitters as well as supports metabolic and detoxifying transformations in the organism.

Thiamin (vitamin B1) influences proper metabolism in the central nervous system, supports cognitive functions and increases tolerance to physical effort. Its deficiency may lead to beriberi disease, which manifests itself mainly in the form of disorders in the circulatory and nervous system, appetite disorders, swelling, drop of body mass. Gentle deficiency of this vitamin, on the other hand, means worse memory and concentration, increased irritability and fatigue and worse mood.

Niacin (vitamin B3) is essential for proper metabolic transformations, supports the activity of the central and peripheral nervous system, takes part in the production of hormones and improves blood circulation. Niacin deficiency primarily gives symptoms of skin inflammation, diarrhea and neurological disorders.

Biotin conditions the course of many metabolic reactions, influences stabilization of glucose level in blood and proper growth and development of the organism as well as helps to preserve beautiful appearance of skin, hair and nails. Biotin deficiency  manifests itself in the form of skin changes (discoloration, psoriasis, hair loss, nail fragility) and neurological changes (depression, apathy, worse mood).

Pantothenic acid (vitamin B5) takes part in energy changes (i.a. in the cycle of citric acid and reactions of oxidation and fatty acid production) as well as influences the synthesis of hormones, vitamins (A and D), neurotransmitters and cholesterol.

Summing up, Seeking Health B Complex Plus is a dietary supplement which contains the whole range of bioactive forms of B-group vitamins in optimal, incredibly effective doses. The preparation is recommended primarily to people who want to supplement deficits of B-group vitamins, lower homocysteine level, facilitate methylation processes and improve the course of many key enzymatic reactions in the organism.

Thiamine hydrochloride


Thiamine hydrochloride - a highly bioavailable form of thiamine, also called vitamin B1. Due to an important role that it plays in carbohydrate metabolism, its increased supply is recommended to people with excessively high concentration of sugar in blood. It facilitates their processing in the organism and supports the activities that aim at restoring optimal glycemia. An important role in the metabolism of nutrients is also played by an integral component of carboxylase coenzyme - thiamine pyrophosphate.

Some source suggest the effectiveness of thiamine in relation to the health of the cardiovascular system, apart from decreasing glucose level in blood, it is also reflected in optimization of blood pressure. Although this aspect of effectiveness of vitamin B1 requires further research, it is another argument demonstrating special needs of taking care of proper thiamine supply by people from the risk group of the circulatory system diseases.

Among people who are especially prone to vitamin B1 deficiencies there are also people fighting with excess weight and frequently drinking alcohol.




Sodium is an important component of the intracellular fluids, and is a regulator of acid-base balance. Along with potassium affects the proper of growth and provides the proper functioning of muscles and nerves. The source of acquisition is table salt (NaCl) and bladderwrack, shellfish, bacon, beef, and of plant beets and carrots. People on salt-free diet should avoid, among others, spicy sauces and smoked meats and sausages.
Sodium deficiency is very rare, at heaving sweating after a long effort (e.g. in the marathon).
Excess sodium increases blood pressure (especially for the elderly), edema and increased thirst. Exceeding the daily dose of 14g a day can cause poisoning.




Inositol is an organic compound from the group of B vitamins soluble in fluids, present in the natural or synthetic form, synthesized in plants, such as brewer's yeast, beans, grapefruit, cabbage, sprout of wheat, melons and animal (liver). Along with choline is included in the lecithin. It affects the cell nutrition of the central nervous system (brain) by reducing the level of LDL (bad cholesterol), this makes it applicable in treatment of Alzheimer's disease and atherosclerosis. It has a calming effect. There has been a beneficial effect of inositol on the skin and hair reported.


Vitamin B6


Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine) is soluble in the liquid. It participates in the metabolism of proteins, fats and carbohydrates. By reducing the amount of fat in the blood do not enable deposition of the body. It helps the absorption of magnesium and vitamin B12 (cobalamin). It works on the muscle antispasmodic and anti-inflammatory pain in the joints. It acts anti. It provides efficient operation of the brain. It increases energy increasing vigor of a man. The demand for vitamin B6 increases during pregnancy and breast-feeding infants. The natural product is: yeast, eggs, wheat germ, meat (liver), wheat bran, nuts, peanuts peanuts, soybeans. There is a hypothesis that can be synthesized by intestinal bacteria.
Deficiency of vitamin B6 causes abnormal metabolism of proteins, decrease in lymphocytes in the blood, causes a feeling of lethargy and fatigue intensifies.
Dosage: 1.5-2.5 mg daily (increased demand during pregnancy and lactation).




Quatrefolic is the glucosamine salt of (6S)-5-methyltetrahydrofolate and also an active form of folic acid. It is an innovative nutrient (fourth generation folate) which is well soluble in water and thus absorbed effectively by the body. As an organic compound ranked among B vitamins, it is necessary for normal functioning at the cellular level.

Adding folates to a diet is recommended especially to pregnant and lactating women. These compounds may contribute to healthy foetal development. According to studies, their intake may reduce the incidence of pregnancy complications.

Some sources report that folate supplementation supports cardiovascular function (blood production) and contribute to healthy immune function.

Quatrefolic may affect the metabolism of homocysteine whose levels increase in the body over time. Adding it to a diet may thus prevent the development of dementia and maintain healthy cognitive functions which is vital to adults, especially the elderly.



Salt (sodium chloride, or table salt), natural source of electrolytes (chlorine and potassium), regulating water and electrolyte and acid-base balance of the body, affecting the nervous system and blood pressure. Sodium is an essential element for the proper growth. The proper dose of salt prevents overheating of the body and solar stroke. It provides the proper functioning of muscles and nerves the body. Chlorine in combination with sodium, is involved in the digestive process and maintains acid-base balance in the body, as antitoxin removes toxic products of metabolism in the liver. Salt is a flavour component and preservative of many foods, nutritional supplements and mixtures of electrolytes, available at

Dosage: no specific standards of consumption, used so as to provide sufficient amount of electrolytes to the body (sodium and chloride).


Calcium folinate


Calcium folinate - a metabolite of tetrahydrofolic acid constituting a perfect form of its supplementation. Tetrahydrofolic acid is a biologically active form of folic acid, especially recommended to people dealing with methylation disorders. Folic acid in the active form is at the same time a promotor of this process, but it requires efficient action for its activation, therefore in case of methylation disorders, folates are the only effective form of supplementation of this compound.

Folic acid is mainly associated with pregnancy. In its active form, it is responsible for the regulation of the development of the neural tube of the fetus, which constitutes a key factor, conditioning its proper development. Providing folates is currently indicated as the most effective form of healthy pregnancy prophylaxis.

Another important aspect of the functionality of tetrahydrofolic acid in the organism is its role in the process of methylation. It positively influences the efficiency of transformations of homocysteine to methionine, thanks to which it demonstrates positive influence on the health of the cardiovascular system. The efficiency of this process is also conducive to maintaining the high concentration of S-adenosyl methionine in the organism. This compound demonstrates special influence on maintaining optimal mental functions and healthy liver.





What is methylcobalamin?

Methylcobalamin is a biologically active form of vitamin B12. It is one of the two forms of this vitamin that may be used as cofactors in various reactions. It differs from popular cyanocobalamin in the presence of methyl group instead of cyanide, thanks to which it releases the organism from the need of neutralizing this harmful factor.

The methyl group from methylcobalamin may be transferred to homocysteine, thanks to which it comes back in the form of methionine in order to be further converted to SAMe, which is the main donor of methyl groups in our organism. These methyl groups may be then used in the processes of creatine production, in neurotransmitter metabolism and as DNA methylation, thanks to which we achieve proper energy level, better well-being and generally better condition of the organism. B12 is a coenzyme for three enzymes: isomerase, methyltransferase and dehalogenase.

Apart from the influence on the nervous system, the supply of vitamin B12 is also very important for the proper synthesis of red cells as well as hemoglobin and anemia prevention.


Methylcobalamin in mono-supplements and complex vitamin preparations may be found in the offer of



Adenosylcobalamin - a biologically active form of vitamin B12, which similarly to its methylated form does not need to undergo additional biochemical transformations in order to enter metabolic pathways in the human organism.

Apart from the best assimilability, adenosylcobalamin is distinguished from other forms of vitamin B12 by its high affinity for regeneration of nervous tissue. It is indicated that this form of cobalamin is engaged in the production of myelin sheaths with key meaning for proper neurotransmission. Apart from this, vitamin B12 is conducive to maintaining optimal functionality of the nervous system, being conducive to the synthesis of neurotransmitters.

Vitamin B12 is also an incredibly important regulator of methylation process, thanks to which its supplementation positively influences metabolism of the whole organism. It is a coenzyme in the conversion reactions of homocysteine to methionine as well as methylmalonyl-CoA to succinyl-CoA. Because of the first reaction, proper supply of vitamin B12 is also conducive to maintaining high concentrations of S-adenosylmethionine, thanks to which it positively influences mental functions.

Moreover, vitamin B12 is a key regulatory factor, taking part in erythropoiesis, i.e. the process of forming red cells. Its improper supply may be the cause of the development of the so-called vitamin B12 deficiency anemia.

Supplementation with vitamin B12 should be considered especially be people on vegetable diets and those who take drugs from the group of proton-pump inhibitors (PPIs) and metformin.




Biotin (vitamin H, co-enzyme R) is in a group of B vitamins, due to the presence of sulphur compounds it is involved in the synthesis of ascorbic acid (vitamin C). Also synthesized in the intestines. It enhances the production of hormones and regulates cholesterol levels. It reduces muscle pain. It prevents hair loss and graying of hair. It soothes the skin inflammations. No toxic effects. Often combined with other B group vitamins and vitamin A. The natural sources of biotin are: whole grain bread, yeast, eggs (yolk), milk, brown rice and cheese.

Daily demand: 100-300 mg per day




Calcium (element chem. symbol Ca, atomic no. 20, the group of alkaline earth metals) is the basic building substance of bones and teeth, in which stored is 99% of the element, in the form of hydroxylapatite. When building bones and teeth, phosphorus is very important in the right proportion. It is a base-forming element and activator of many enzymes (ATPase) necessary to release the energy of ATP. It has a significant effect on blood clotting and regulates blood pressure and neuromuscular conductivity. Thanks to the reduced permeability of cell membranes, it soothes the symptoms of food allergies. Calcium is actively involved in the metabolism of iron interacts with vitamins A, C and D and phosphorus, magnesium. Natural source of calcium are animal products (dairy products, sardines, salmon, sprats eaten with bones) and plant products (nuts, soybeans, sunflower seeds). Absorption takes place in the small intestine (less in the colon), it has an effect on the level of lactose, insoluble fibre, organic acids, alkalinity (low pH). The best absorption have organic compounds (lactates, amino acid chelates etc.). Obstructing the absorption of calcium is caused by: phytic acid and oxalic acid as well as excess fat. Scientific studies have confirmed that the combination of calcium, magnesium, boron and vitamin D in dose 3 mg / 24h effectively prevent osteoporosis. Supplements on the market are both mono-preparation supplements (enriched with vitamin D3) and multi-component supplements, available at
Calcium deficiency disorders manifested in the construction of the bones (osteoporosis) and iron metabolism. The symptoms are: rickets, cramps and muscle tremor, osteoporosis.
Excess result
ing from an overdose of calcium supplements containing vitamin D3 for children and adults overdose of calcium (hypercalcemia). Symptoms of hypercalcemia are: lack of appetite, vomiting and constipation.
The dosage administered in various publications
are inconsistent: 800 - 1000 mg / 24 h (100 - 500 mg / 24h)



Choline belongs to the soluble in liquids group of B vitamins. It is an organic nitrogen base containing lecithin, and acetylcholine. Together with inositol is involved in the metabolism of fats and cholesterol metabolism, preventing its accumulation on the walls of arteries and deposits in the gallbladder. With the penetration of the brain, contained lecithin improves its action and improves memory. Used in the treatment of age-related diseases (Alzheimer's). It occurs in plant foods: yeast, wheat germ, lecithin, green leafy vegetables and egg yolks.


Choline Bitartrate


Choline bitartrate a combination of one molecule of tartaric acid and choline, and in this embodiment is a precursor of acetylcholine (neurotransmitter). The human body is able to intracellular synthesis of choline, using the amino acid and vitamin B12. Because of the possibility of shortages of the above mentioned substances, it is necessary to supplement them with supplementation. Choline is a component of lecithin, which is the building substance of cells conditioning the proper functioning of the nervous system, and sphingomyelin, acting as an insulator of nerve tissue. Bitartrate affects the course of fat metabolism. In the sports supplementation of choline, bitartrate is used in the stimulating supplements,, affecting concentration and programs of weight control (fat reduction).
Dosage: 1-3 grams per day.
