Your OCD serves you well; you caught two precise details that very few people would ever notice. Well Done and Thank you for bringing it to our attention. In one case the label has a typo, but in the second case the label is correct. Send me your address and I’ll get you out a bottle of the PRE Extreme out to you for your efforts.
Great catch on the Yohimbe typo. The actual ingredient in NutraBio PRE Extreme is Yohimbine Hcl, so that is a typo. We also manufacture an encapsulated Yohimbe which uses a natural Yohimbe Extract yielding 8mg of Yohimbine alkaloids. Thank you for bringing it our attention; the website is being corrected right now, and existing label inventory has already been quarantined for destruction.
With regard to the magnesium, our label is actually correct. The FDA regulation specifies that mineral values do not need to be claimed on the label unless you are explicitly adding it to supplement for the purpose supplementing the mineral in the diet or if you are making any claims about the mineral. In PRE Extreme, we are adding Creatine MagnaPower which is creatine chelated to 8% magnesium, for supplementing creatine into the diet. We make no claims about magnesium, so we do not need to list its value on the label. We could, but decided not to.
Copied from the FDA’s Dietary Supplement Labeling Guide: Chapter IV. Nutrition Labeling. Must I declare vitamins and minerals (other than vitamin A, vitamin C, calcium, and iron) listed in 21 CFR 101. 9©(8)(iv) and ©(9)? No. You are only required to declare them when they are added to the product for purposes of supplementation, or if you make a claim about them.
