as vitamine D3 from lanolin requires a long process and the use of different detergent and solvent. I would like to know:
1) what is the process to extract the vitamine D3 from the lichen. Cold extraction? alcool? water? solvent?
2) Does it need radiation like the provitamine D3 from lanolin?
3) How sustainable are your methods
Thanks for taking the time to answer
Hi, we use water and alcohol during the extraction process. We don't require any harsh solvents and we are not performing UV conversion of pre-vitamin D.
