Is Glutathione Affected by Caffeine or Milk Tea?
Many Filipinas ask this when they start their glow journey:
“Pwede ba akong uminom ng coffee or milk tea habang nag gluta?”
The answer is reassuring.
Glutathione still works, but timing matters.
Here is the full, science-guided explanation.
🌿 1. Caffeine Does Not Destroy Glutathione, but Timing Affects Absorption
Your glutathione supplement releases best when your stomach is not too busy digesting strong stimulants like caffeine.
Coffee can:
✔
speed up digestion
✔
increase stomach acidity
✔
shorten the time capsules stay in the intestine
✔
slightly reduce nutrient absorption when taken too close
This does not “kill” glutathione.
It simply means you should take them separately for best results.
Best timing:
• Take glutathione first upon waking
• Drink coffee 30 to 60 minutes later
This simple timing gives your body enough space to absorb your supplement.
✨ 2. Milk Tea Has a Stronger Effect Because of Sugar and Dairy
Milk tea affects glutathione more than black coffee because of:
✔ High sugar
Sugar competes with nutrients and may slow antioxidant activity.
✔ Dairy
Casein (milk protein) may bind to antioxidants, making them less effective.
✔ Tea tannins
Tannins can reduce absorption of certain active ingredients.
Milk tea will not stop glutathione completely, but taking them together is not ideal for glow or digestion.
Best timing:
• At least 1 hour between glutathione and milk tea
• More time is better if your milk tea is extra sweet or extra creamy
🌱 3. What Happens If You Take Them Together?
Your glutathione supplement releases best when your stomach is not too busy digesting strong stimulants like caffeine.
Coffee can:
•
slower glow progress
•
uneven absorption
•
weaker antioxidant response
•
less stable melanin balance
You will still glow, but results may come slower.
Many Ishin Premium users who fix their timing see faster improvement in:
✔
brightness
✔
clarity
✔
even tone
✔
stress-related dullness
💡 4. The Best Way to Take Glutathione for Maximum Results
For best glow:
01
✔ Take on an empty stomach
Best absorption happens before breakfast or before bedtime.
02
✔ Pair with Vitamin C
Boosts glutathione recycling and glow effect.
03
✔ Space out coffee and milk tea
30 to 60 minute gap is enough.
04
✔ Stay hydrated
Glutathione travels better with good water intake.
Glow depends on consistency plus smart timing.
