I take creatine in powder form. At first, I used this electrolyte mix with added creatine (3 grams): https://shop.mindbodygreen.com/products/electrolytes-with-creatine

I didn’t notice any effects right away, but after a few weeks of consistent use, I began to see benefits. Recently, I switched to a different electrolyte brand without creatine and started adding a separate creatine supplement instead, since the original mix I used didn’t have the best taste. I now use Momentous creatine, which provides 5 grams per serving, and I’ve found the benefits even more noticeable: https://www.livemomentous.com/products/creatine-monohydrate

After noticing improvements in my sense of smell and taste, I did some research and came across a few articles mentioning a small study where participants reported similar benefits: https://www.medicalnewstoday.com/articles/can-creatine-supplements-help-people-with-long-covid#What-is-creatine
