No Life Without Enzymes

Every living creature needs enzymes. Enzymes are indispensable for many important bio-chemical processes in our body.

  Regulator increases the availability, mobility, and uptake of nutrients. It also benefits plants by depositing silicon in cell walls, increasing stress resistance, stimulating immune response and creating more dry weight.

Aptus – Easy & Low-cost
