I supplement iron and vitamin C, as my iron is currently on the lower end of normal (after a few years of being vegan it was too high, go figure).
I tried creatine for a few months but didn’t notice much difference in the gym and while rockclimbing.
I drink a lot of B12 fortified soy milk which seems to cover that.
I have about 30g of protein powder a day with a good range of different amino acids to help hit 140g a day.
I have a multivitamin every few days.
I have iodine fortified salt that I cook with sometimes.
I’ve thought about supplementing omega 3 or eating more omega 3 rich foods but never got around to it.
8 years vegan for reference.
Thanks for writing this! I had one thought regarding how relevant saying no to some of the technologies you listed is to AGI.
In the case of nuclear weapons programs, the use of fossil fuels, CFCs, and GMOs, we actively used these technologies before we said no (FFs and GMOs we still use despite ‘no’, and nuclear weapons we have and could use at a moments notice). With AGI, once we start using them it might be too late. Geo-engineering experiments is the most applicable out of these, as we actually did say no before any (much?) testing was undertaken.
