00:00:00,000 --> 00:00:05,458
Glutathione is a molecule our cells make and use in antioxidant chemistry.

2
00:00:05,458 --> 00:00:12,542
That biological role is real. The evidence for a particular supplement or injection is a separate

00:00:12,542 --> 00:00:16,042
question.

4
00:00:16,042 --> 00:00:20,708
Small randomized studies have examined oral glutathione and skin measurements.

5
00:00:20,708 --> 00:00:27,375
Their limited size, duration, and selected participants constrain what they can tell us about lasting

6
00:00:27,375 --> 00:00:30,875
cosmetic effects.

7
00:00:30,875 --> 00:00:36,750
Results from an oral product do not establish the safety of an injection.

8
00:00:36,750 --> 00:00:41,833
Route, formulation, manufacturing quality, and the outcome being measured all matter.

9
00:00:41,833 --> 00:00:47,708
CDC states there is no FDA-approved glutathione drug product in the United States.

10
00:00:47,708 --> 00:00:53,958
Describing something as natural or an antioxidant does not settle its benefits or risks.
