What's the source of microcrystalline cellulose used? does it require harming animals to extract the ingredient?

Microcrystalline cellulose (MCC) for industrial purposes is usually obtained from wood pulp and purified cotton linters. Each of these is a “natural” source, cotton is a high value-added crop and wood pulp generally originates in some manner from deforestation

Hello - is this halal? Anymore for home strength?
