⚠️ Caution and Notes

• Your urine may turn dark yellow after consumption. This is a completely normal phenomenon as Vitamin B2 (Riboflavin) is expelled from the body.

• The pills are a bit large, as is typical for American products, so those with smaller throats should drink plenty of water when taking them.

• As it may cause an upset stomach if consumed on an empty stomach, it is recommended to take it during or immediately after a meal.
