Whether 500 mg of glutathione is enough for skin whitening depends on several factors, most importantly its co-administration with Vitamin C and individual body weight. The reference provided highlights the importance of Vitamin C and appropriate dosage based on body weight.
Glutathione and Skin Lightening: Key Considerations
The effectiveness of glutathione for skin whitening hinges on these aspects:
-
Vitamin C Co-administration: The provided reference states: "Glutathione efficacy in skin lightening works only if it is taken with Vitamin C at least equal or twice its dosage". This means that to see potential skin lightening effects, you would need at least 500 mg (if not 1000 mg) of Vitamin C alongside the 500 mg of glutathione.
-
Dosage Based on Body Weight: The appropriate dosage is dependent on an individual's weight. The reference suggests a "Standard dosage is 20-40 mg/kg of body weight". Therefore, for a 60 kg person, the required glutathione would be between 1200-2400 mg, a quantity higher than the 500mg in the original question.
- Example:
- A person weighing 50 kg would need 1000-2000 mg of glutathione.
- A person weighing 75 kg would need 1500-3000 mg of glutathione.
- Example:
-
Timing of Administration: "Best if taken at night 2-3 hours after last meal for better absorption".
-
Duration of Treatment: "3-6 months" is the duration mentioned in the reference.
-
Frequency: Dosage is suggested "once or twice in a day".
Is 500 mg Enough? A Summary
Given the information, 500 mg of glutathione alone is likely not sufficient for noticeable skin whitening in most individuals. It needs to be combined with an equal or larger dose of Vitamin C and might need to be increased depending on an individual's body weight to be in line with the 20-40 mg/kg dosage outlined in the provided reference.
