Alkylglycerols are highly active natural substances with multiple effects on the human body, present in bone marrow and in breast milk. They activate the immune system (stimulate macrophages - the first line of battle against antimicrobial agents in infections). They show anti-cancer properties by inhibiting protein kinase C - a key factor in cell growth. They have a protective effect against radiation (they protect the lipid membranes of healthy cells - lipid structure), they stimulate the production of erythrocytes and leukocytes.
