MERIVA's patented curcumin in the form bound to phosphatidylcholine (lecithin) with absorbability almost 30 times higher than the combination of curcumin and piperine alone, as found in a clinical study . Curcumin itself is very poorly absorbed by the body from the digestive tract (only a few units of percent), therefore, to enhance absorbability, it is often mixed with piperine (extract from black pepper), which increases its absorbability by up to 100%. Phosphatidylcholine in this form of curcumin also ensures high absorbability by binding curcumin molecules to each other and easily transporting them into the bloodstream. High absorption is one thing, but the most important feature of MERIVA curcumin is a much better profile of curcuminoids in the blood plasma due to the high content of dementhoxycurcumin, which is considered more important for anti-inflammatory effects.

Quatrefolic® is a form of metabolized folate that the body owns and can use. This is vitamin B9, also called folate or folic acid. The common form of this vitamin is synthetic folic acid, which is not the body's own substance and must be metabolized and methylated into a form that the body can use. Surprisingly, even folate, which is contained in fresh leafy vegetables, must be methylated before it can be used. Most multivitamins and preparations with folic acid contain, in the vast majority of cases, a cheap synthetic form - folic acid. However, doctors recommend the methylated form, i.e. folate, but the disadvantage is the higher price. A sufficient amount of folate is important both at the time of conception and at the very beginning of pregnancy, as its deficiency increases the risk of certain disorders. Its sufficient amount in the body is also very important, because in the first month a woman often does not even know that she is already pregnant. Supplementing with folate using a reduced, body-own version of folate from the brand Quatrefolic is a convenient way to supply increased amounts of folate during or before possible conception. We do not recommend folic acid / folate / vitamin b9 for people, especially for long-term use.

Magnesium threonate is the newest form of magnesium, the production of which is patented, and which consists of a unique combination of the mineral magnesium and threonate (metabolite of vitamin C). Magnesium is an indispensable mineral for modern times, it serves as a cofactor in a large number of body processes and is also indispensable for the metabolism of bones and the nervous system. The advantage of L-threonate, the most advanced form of magnesium, is its easy absorption through the brain barrier. This makes it very different from other magnesium products (including otherwise well-absorbed forms such as malate, bisglycinate, etc.). Due to its higher price and lower content of elemental magnesium compared to other forms, magnesium threonate is not very suitable for supplementing magnesium in case of a total magnesium deficiency. On the contrary, it is suitable for its unique cognitive effect on the brain and nervous system. The latest research has also revealed an unexpected application of threonate for hair restoration and growth.

Bromelain is a digestive enzyme extracted from pineapples, mainly from the stem and unripe fruit. To support digestion, it is taken with food and to act as a systemic enzyme, it is taken on an empty stomach between meals. Bromelain is produced by cooling pineapple juice, followed by centrifugation, ultrafiltration and freeze-drying. Quercetin is the most studied of all bioflavonoids. It is contained in a large number of fruits and vegetables, but its biggest sources are apples and onions. Quercetin is usually not very effective on its own, but its synergies with a large number of other substances are interesting. For example, it increases the absorbability of the catechins EGCG from green tea or curcumin, an extract from the turmeric plant.

Zinc is received in food mainly thanks to the consumption of red meat. It is found in very limited quantities in other types of protein. Zinc is also very important for the formation of T. and many other processes. At higher doses of zinc, toxicity can begin to manifest itself, so it is necessary to keep the total intake below 50 mg of zinc per day. The form in which zinc is taken is also important, the most natural and least toxic is the chelated form of zinc, when zinc is bound to amino acids and easily absorbed by the body in this form. Zinc is essential for cell reproduction and is present in all tissues, organs and fluids of the body. In this product, it is available in an advanced amino acid chelate complex as zinc bisglycinate for optimal absorption.

Ashwagandha is a valued herb used in Ayurvedic medicine. Ashwagandha in translation means, among other things, "the smell of a horse", which is related to the strong smell of the crushed root, which is traditionally used. Among the active substances in ashwagandha are mainly Withanone, Withaferin A, Withanolides and other complexes and variants thereof. Different dietary supplements contain very different amounts of active withanolides, which is due to different raw materials and processing processes, so it is important that the extract is standardized to a certain percentage of total withanolides. Due to the very unpleasant taste of the powder, ashwagandha in capsules is the easiest way to take it.

This formulation contains the highest concentration of mature garlic extract per capsule. This is garlic processed by a special method, which preserves the main active substances in garlic. Selected varieties of the strongest clove garlic, grown using the organic method, are fermented for 20 months in stainless steel tanks. This results in the transformation of volatile sulfur compounds into more stable complexes and new molecules. There is also a concentration of the important sulfur compound S-Allyl Cysteine, which is up to 8 times higher in this garlic extract than in fresh garlic. At the same time, this processing process removes the strong smell that we know from fresh garlic. It is therefore an equivalent alternative to the use of fresh garlic, the known beneficial effect of which requires the consumption of more than 1-2 grams of fresh garlic per day. High consumption of fresh garlic, however, can bring, in addition to great pain in the mouth, also a potential burn of the digestive tract. Thanks to the metabolism of the active ingredients of fresh garlic in the body, they are released by the body and also cause body odor from sulfur compounds, which is not very socially appropriate. The advantage of this fermented garlic is the very convenient consumption of a sufficient amount of garlic without odor, burning and other adverse effects. Garlic is a wonderful plant consumed by our ancestors for centuries, and one of the strongest varieties of clove garlic is traditionally consumed in our region. Kyolic Aged Garlic extract is made from the highest quality organically grown strong varieties of garlic. Now in the 21st century, we can comfortably enjoy the powerful effects of what helped our ancestors from time immemorial without the unpleasant smell.
