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.

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.
