A TSH value of 0.09 is low and indicate need for stepping down of levothyroxine dose.
Your doctor will guide you in this.

Brief Answer:
that is also unlikely the cause.
Detailed Answer:
Hi dear,
Thanks for following up.
Though it is better to stick on a single brand, change in brand is unlikely to cause significant changes in bio availability or serum levels.
There is nothing to worry in this. Thyroxine demand is common to vary with time and just need regular follow up with dose adjustment accordingly.Also, the metabolic demand decrease as our age advances.
Hope you got cleared now.
