Naturally sourced is a comforting phrase with no precise meaning on a supplement label.
Several of HoneyFil's ingredients are plant or bee-derived extracts, which fits the idea of natural sourcing. Zinc bisglycinate, though, is a mineral bonded to the amino acid glycine, and cholecalciferol is a specific form of vitamin D. Whether those are derived from natural sources is not stated.
Supplement labels have no single legal definition of natural, so it is a brand description, not a verified fact.
Natural does not mean safer or free of interactions. Ashwagandha, fenugreek and zinc are all natural substances that can interact with medications, as the page itself notes. It also says nothing about amounts, purity or contaminants. Judge the product by its label, testing documents and your doctor's view, not by this word.
