Correct Energin dose?

[AinmAnseo]

For energin, on page one, I see that the dosage is:
"Serving size - 25 drops
Each serving contains:
Vitamin B1 (Prosultiamine): 25mg
Vitamin B2 (Riboflavin-5-Phosphate): 15mg
Vitamin B3 (Niacinamide): 100mg
Vitamin B5 (D-Panthenol): 50mg
Vitamin B6 (Pyridoxal-5-Phosphate): 6mg
Vitamin B7 (Biotin): 1mg"

I see some later posts saying that 80 drops is now 2 doses?
Does anyone know what is correct?
