The latest-generation heart and circulatory preparation: If you want normal blood pressure*, normal heart function**, normal homocysteine metabolism*** and healthy vessels**** - voilà - it couldn't be better. We are able to withstand any comparison.

Based on over 140 scientific works: Well-founded, sensible, intelligent composition. Zestonics develops and produces all formulas itself. 100 % quality.
All-inclusive nutrients: Arginine Base, Citrulline, Potassium, Zinc, OPC Red Wine Glyphenol + Pine Bark Extract OPC, Tumeric, Milk Thistle, Rosemary, Reveratrol, Q10, B1, B2, B6, B12, C, Folate (natural form of folic acid) and Piperine.
