Good to know, thanks. So, what brands of cheese are safe though? It seems all of the ones sold in stores list one of these on the label.
there are some cheeses that are safe. Some mozzarella uses vinegar only. Other than that you have to go for the higher end cheese at Whole Foods if you can afford to. Some supermarkets have a second cheese second near the produce department where they sell "gourmet" cheese, for instance parmegiano reggiano, and these often are made with real animal rennet (but not always).
I contacted Kerrygold because their label said "rennet" but they responded that all their products are made with fake enzymes now.
But even Boars Head has some cheese they sell that is made with "animal rennet."
btw i think pregnenolone is made from diosgenin/wild yam nowadays? not sure of before. vitamin C switched from citrus fruit extraction to the mold/fungus forms used today.
i dont have links, but remember reading almost all malic acid on market is a synthetic toxic form, from mold or something. this is why "citrulline malate" supplements cause side effects...
I remember I would try citrulline malate for bodybuilding purposes, and it would swell up my face, even my airways would have this odd feeling of like expanding or swelling..
i made excuses like oh it must be allergies coming in but after the second or third time trying the citrulline it was obvious it somehow swells the face up and causes some kind of allergy type effect...
if you search malic acid side effects online, you just get total nonsense, like every article says its an organic acid, has no side effects besides stomach upset for small amount of people.
if you look at these things on supplement forums, the excuse is "oh the molecule is the same, so it shouldnt matter if the source is fruit or mold or something synthetic"
btw @haidut i think taurine side effects could also be relevant and its th same thing, it used to be extracted from bull testicle, now its almost always synthetic. TUDCA supplements used to be from bear bile (wonder what else was done since you rarely hear of bear being sourced for food or supps) now theyre synthetic usually
the vegetarian/vegan trend also encourages these companies to do things like switch their sourcing from safer animal sources, to vegetarian and often toxic sources, like gelatin capsules to cellulose capsules
pecorino romano usually has animal rennet, but the taste is very strong, i cant eat it unless its on a pasta or potato or something...
