A Comparison of Sodium Citrate and Sodium Bicarbonate Ingestion: Blood Alkalosis and Gastrointestinal Symptoms, 2022
500mg/KG BW sodium citrate (SC) is about equally effective as 300mg/KG BW sodium bicarbonate (SB) in raising blood pH and blood HCO3- in healthy people.
The increase in the SC group however took about 1h longer to set in and also lasted for longer than the SB:

I'd say give the citrates a try for simplicity although in this study, the gastrointestinal side effects/complaints were comparable between SC (~35g!) and uncoated SB (~21g!).
Whilst the SC also does meddle with stomach pH, it won't react to CO2 (burping, flatulence).
The release of HCO3- from citrate happens indirectly through liver tricyclic-acid metabolism.
And of course use potassium citrate or a citrates blend instead of the sodium salt.
@mossy @ena There are several online suppliers of potassium citrate capsules (~1110mg per capsule, whereof 400mg K) as an affordable alternative to buying the pure powder and dissolving a teaspoon in water two times a day.
10grs of potassium citrate contain about 3.6grs K, 10grs of potassium bicarbonate ~3.9grs K.
Although the same amount (by weight) of citrate is not as effective as bicarbonate, on a regular daily basis I think one can shift between using either.
