Curious question: If this is a specific blend
Curious question: If this is a specific blend, NEC Defend, then why do the capsules keep changing color? Lot# 2403055A=Green Lot# 2412079A=Tan Lot# 2412079A=White The last two are close & have the same date, but I am thinking in the past there may have been a pink lot (but didn’t keep a bottle). You have so many choices that I am concerned they are labeled correctly. Thank you for asking for comment.

Product is questionable, customer service stinks
I'm not sure about the product but sure the customer service stinks. Called, was told someone would call me but never did. So I did the customer contact email with no response. My concern was that the supplements in my 2nd shipment were a different color and size than the 1st shipment, which concerned me.
