FD&C Blue #1 has no place in a health supplement. The FDA put out public health advisory for this chemical.

I HAVE BEENTAKING "CALM" BRAND MAGNESIUM AND IT OBVIOUSLY WORKS, WITH A POTENCY OF 330MG/4GUMMIES AND THEY HAVE A DISTINCT MAGNESIUM TASTE. (YOU KNOW WHATTHIS IS IF YOUVE EVERR HAD EPSOM SALTS OR LIQUID ORAL MAGNESIUM SUPPLEMENTS.)<br />THE PUREFINITY BRAND PRODUCT HAS NO MAGNESIUM TASTE DESPITE CLAIMING TO HAVE 600MG/2 GUMMIES, ESSENTIALLY 4X THE POTENCY IN A SIMILIAR SIZE GUMMY.<br />AND THERE IS THE ISSUE THAT THERE IS ZERO HEALTH EFFECT WHEN i TAKE THEM COMPARED TO THE RELIEABLE EFFECT OF THE OTHER BRAND.<br />I DOUBT VERRY MUCH THAT THERE IS "LAB VERIFIED POTENCY" AS CLAIMED ONT HE LABEL - AND LET THEM POST IT HERE IN THERE PRODUCT PAGE IF THERE IS A LEGITIMATE LAB THAT HAS IN FACT TESTED THESE GUMMIES TO ASCERTAIN POTENCY.<br /><br />IT IS DANGEROUS TO BE SELLING A PRODUCT WITH LOW POTENCY AS MAGNESIUM IS USED BY PREGANT WOMEN ( AND OTHERS) AT RISK OF HIGHBLOOD PRESURE TO REDUCE HBP RISK. MAGNESIUM IS ALSO USED TO KEEP BOWEL MOVEMENTS SOFT, AND THE RISK OF CONSTIPATION IN PREGNANCY/OTHER MEDICAL SITUATIONS IS NOT WITHOUT COMPLICATIONS. FOR INSTANCE AUTISTIC KIDS OFTEN TAKE MAGNESIUM TO HELP WITH THEIR CHRONIC CONSTIPATION, AND IF THEY GET BACKED UP IT CAN HAVE NEGATIVE IMPACT ON THEM.<br /><br /> THIS PRODUCT I SUSPECT IS A FRAUD THAT IS UNFORTUNATELY PLACING PEOPLE'S HEALTH AT RISK.

Recommended Daily Allowance for "Elemental Magnesium" is approximately 300 to 400mg for women and men respectively.<br /><br />Please note that is for Elemental Magnesium - not Magnesium Citrate which only contributes a smaller part of Elemental Magnesium. Various other Magnesium products clearly specify this as: "Magnesium - xx mg (from Magnesium Citrate, Glycinate, etc.)". So the labeling on this product is misleading - this may lead to inadequate dosage for people. So please beware.

Claimed I'd get a free bottle after 15 days when I them filled out a form with proof of purchase and never heard from them. That was almost a month ago. Very disappointed.

I have had sleep apnea for 7 years and have tried 3 different prescription medications that improved my sleep, but left me without energy during the day. After trying many supplements, I came across this product. I have noticed that my sleep quality has improved without compromising my energy during the day. I will continue to use this because it absolutely works!

First order had a hole in the safety seal. Applied for refund, received another one promptly and was unable to open the lid! I'm mag deficient so I began using the first bottle because it had 2 safety seals and the outside one WAS intact and I couldn't wait any longer. Later, my husband was able to barely get the lid off... and the inside safety seal was torn AGAIN! But this time, in a distinct spiral pattern.... here's what's happening- the inside of the lid has this almost glue like substance on it. It adheres to the safety seal and gets ripped when the lid is open. So the second one ripped as he unscrewed the lid. So- if that suffices for those that think they had a bottle that had been "tampered" with, there you go. It hasn't. To the seller- I never mailed my first refunded bottle back because I couldn't open the second one. Then my hubby did because I told him it was stuck. So now I have 2 opened bottles and none to send back. Charge me for 2 if you want, but you may want to look into this. Also, seems like this much magnesium should loose your bowels a LITTLE, but this does not, making me just hope that I'm still getting this much magnesium. Tastes great.
