Can you drink thai iced tea while pregnant?
In moderationYes, one Thai iced tea a day is fine. It is brewed strong from black tea, so a 16 oz glass runs roughly 50 to 100 mg of caffeine, which fits inside the 200 mg daily limit as long as you are not stacking it on top of coffee.
Why
The only real issue with Thai iced tea is caffeine. The base is black tea brewed much stronger than a normal cup, so a large glass can land near half of the 200 mg per day that ACOG and the NHS both set as the pregnancy limit, and high caffeine intake is linked to low birth weight and miscarriage. The dairy is not a concern: traditional cha yen is made with evaporated and sweetened condensed milk, both of which are heat treated and shelf stable, so there is no unpasteurized dairy risk. Shop strength varies a lot, so if you have already had coffee that morning, order a small or ask for half the tea base.
Safer alternatives
- a 12 oz Thai tea instead of the 16 or 24 oz size
- Thai tea made half strength, most shops will do it if you ask
- iced rooibos or herbal tea with condensed milk for the same creamy sweetness, caffeine free
- nam manao, Thai lime soda, or fresh coconut water

Frequently asked questions
How much caffeine is in Thai iced tea?
Roughly 50 to 100 mg for a 16 oz glass, depending on how strong the shop brews its tea base. That is somewhere between a cup of regular tea and a small coffee. One a day leaves plenty of room under the 200 mg limit.
Is the condensed milk in Thai iced tea safe during pregnancy?
Yes. Evaporated milk and sweetened condensed milk are both heat treated and canned, which is why they keep at room temperature. Neither carries the Listeria risk that unpasteurized milk does.
Can I have Thai iced tea with boba while pregnant?
Yes. The tapioca pearls are starch and sugar with no caffeine, so the count stays the same as a plain Thai tea. Just remember the drink itself is usually 16 oz or larger, so keep it to one that day.
