Received fresh product that expires in 2027 !
I like Red Sea and the 5 liter bottles are a great savings! What I do not like is old product or product expiring very soon. Happy to report that this was very fresh product!

Authentic
I only use about 30ml a day so this is still economical. I tried buying the powder on amazon and what I received was counterfeit (it was used, filled with baking soda, and resold). This container came sealed.
