Q: Can Vitamin C be used to remove chlorine and chloramine for bathing purposes?
A: Exposures via respiration do not occur from use of chloraminated drinking water. Based on
personal preference, some individuals may choose to reduce exposure to chlorine or chloramine.
Vitamin C (ascorbic acid) has recently been included in AWWA Standard (AWWA, 2005b) as one
of the methods for dechlorination of disinfected water mains. SFPUC and other utilities have used
Vitamin C for dechlorination prior to environmental discharges of chlorinated and chloraminated
water. Since ascorbic acid is weakly acidic, the pH of water may decrease slightly (Tikkanen et
al., 2001). Ascorbic acid has been used for a long time as one of the dechlorinating agents for
preservation of chlorinated or chloraminated water samples for laboratory analysis.
The removal of chloramine is not necessary from a public health perspective; however, some
customers may choose to remove either chlorine or chloramine for bathing purposes. There are
no NSF International certified point of use devices utilizing Vitamin C; however SFPUC
determined that 1000 mg of Vitamin C (tablets purchased in a grocery store, crushed and mixed
in with the bath water) remove chloramine completely in a medium size bathtub without
significantly depressing pH. Shower attachments containing Vitamin C can be purchased on the
Internet, as well as effervescent Vitamin C bath tablets. The 1000 mg effervescent Vitamin C
tablets dissolved readily without residue but may depress pH more than regular Vitamin C tablets
purchased in grocery stores. Some shower attachments with Vitamin C marketed on the Internet
are effective in removing chloramine; however, the claims posted on the Internet as to their
replacement frequency appear to overestimate the duration when the shower attachment is
effective. There are reports of the benefits of Vitamin C for skin care (Griffith, 1998) and various
cosmetics are available in stores that contain Vitamin C. SFPUC does not recommend for
customers to use Vitamin C for bathing purposes and anyone desiring to do that should consult
with their physician.
Now how to figure out how many gallons are in the bathtub they used 1000mg for and converting to 5gal lol!
I recently bought some powder off amazing and just sprinkle a bit in, stir it up and don’t think twice about it. Being in living organic soil I do t care about PH anyway! Don’t overthink it!
From what I’ve read it does not remove chlorine or chloramine but it causes a chemical reaction that strips them down into separate non microbe dangerous compounds. I’m lucky enough not to have chloramine in my water and found growing with my tap water as is just fine but for a little sprinkle of powder maybe I’ll go to the next level!
