What is actually in the bag, additive by additive
Strip the menu names away and most UAE drip offerings reduce to a short list. The base is 500 ml to 1 litre of normal saline or Ringer's solution — this is the part with the strongest evidence, because fluid and electrolyte replacement is a century-old, well-understood therapy. On top of that, providers add B-complex vitamins (involved in energy metabolism, genuinely useful if you are deficient, otherwise excreted), vitamin C (modest evidence at normal doses; high-dose infusions require a doctor's order), magnesium (muscle cramps, migraine-adjacent uses), zinc, and anti-nausea or pain medication where a physician has prescribed it.
Then there is the premium shelf: glutathione, marketed for skin brightening, and NAD+, marketed for energy and longevity. The candid position — the one a good doctor will give you off the record — is that evidence for the cosmetic and anti-ageing claims is thin, and regulators in several countries have pushed back on skin-lightening glutathione marketing specifically. These infusions are not necessarily unsafe when properly administered, but you are paying AED 800–1,500 for something whose benefit is substantially less proven than the saline it is dissolved in. Buy them with clear eyes.
