5-Star Product w/ Falsely Advertised Quantity: 79.53 (not 90) Days Total Supply = 10.47-Day shortage
I received my Amazon.com order of three containers of Gundry MD Vital Reds.  The manufacture date (not to be confused with a "sell-by date") of all three containers indicated that the product was 196-days-old upon arrival.  This is more than half the 365-day shelf life of a typical consumable product.  Since I already planned to fully consume all of this product within less than 169 days (365 days of assumed freshness - 196 already aged upon arrival = 169 days of assumed freshness remaining), this excessive age upon arrival was not actually a problem for me.  I am mentioning it only as an objective observation.  The false advertising about product volume is mildly concerning.  Each container contains 3.984 ounces (not 4.0) = 112.95 grams of product.  The complementary "scoop" included inside each container measures 5.0 cubic centimeters (cc) dry = 5.0 milliliters (ml) dry = 1.0 teaspoon (tsp) dry = 4.26 grams (g) dry.  One "scoop" is falsely advertised as 3.765 grams, which would neatly equal 30 days of supply, if it were actually true (112.95 grams/container ÷ 3.765 grams/day = 30 days/container, as FALSELY advertised).  Assuming I use exactly one level "scoop" per day, I will truly get 26.51 (not 30) "scoops" (i.e., days) per container.  This is 3.49 "scoops" (i.e., days) less than the 30 "scoops" falsely advertised, but it is close enough for my needs.  With 26.51 days of product in each container • 3 containers, I will have enough product for 79.53 (not 90) days total.  90 days falsely advertised - 79.53 days of actual product = 10.47 days short of the falsely advertised amount.  Again, this 10.47-day shortage is acceptable by my very forgiving and tolerant standards.  Although the blatant fakery of product measurements is not necessarily a deal-breaker for me, it would be helpful if the product measurements advertised were to actually be congruent with reality.  At this very high (but well worth every penny) price-point, many other consumers might not be as forgiving as I am.  The product itself is worthy of five stars!  The obvious lack of truth-in-advertising regarding product measurements is worth removing one star.  Thus, I gave four stars overall.
Rating: 4 stars
