The water's producer, Taranaki farmer Vernon Coxhead, has since pulled back from claims it was a game changer for cancer sufferers.
A disclaimer has gone up on the site, where the product is still being sold, that Te Kiri Gold is not a medicine.
Meads, who said he was still being provided with the product, had previously claimed it gave him a "better quality life".
However, today he was less confident about its actual benefits when asked if he was finding it helpful to keep drinking the water.
"Well, not really, I wouldn't be here otherwise."
A Waikato DHB spokeswoman said Meads had been discharged from hospital this afternoon.
Meads' wife Verna declined to speak with the Herald about Meads' condition and asked for privacy.
