While some guests have found relief from leg cramps and improved sleep, the overall sentiment leans towards dissatisfaction with the new formulation. Guests are seeking a return to the original formula that worked well for them, highlighting the importance of transparency in ingredient changes.

I’ve been using this supplement for years now and love this brand. I tend to purchase it from Target when they offer a special discount because they have great prices on them.

Terrible labeling
Very deceptive labeling, as it’s extremely difficult to figure out what type of the many magnesium supplements that exist this is. I finally found it after reading another negative review that it is magnesium oxide which for months has been causing me to have very loose and messy bowel movements. I will avoid naturemade products going forward.

I'm not sure it will help.
The label claims in big letters that this magnesium supports nerve, heart, and bone health, but 95% of the formula is magnesium oxide. This form has very low absorption and does not provide the advertised benefits. The marketing does not match the actual ingredients. Very disappointing and misleading. What to do?

change in formula and color is NOT GOOD
Since the change of “color” this magnesium is not as effective. As in other reviews, there is a change in the ingredients and it is DOES make a difference in the effectiveness.

Stay away from this type of Magnesium
You should be sued for how misleading your label is! Magnesium oxide is not like other magnesium. It’s nothing more than a laxative! I didn’t realise until my stomach got wrecked! I wish I had looked at the reviews… turns out this used to be a good product until you replaced it with cheap oxide. Maybe it’s time you listened to your consumers. I’m staying away from this brand forever.

A godsend for leg cramps
My legs cramped up every night. I was told to try magnesium pills. Since I take multi vitamins from Naturemqde, I decided to try their magnesium pills and what a difference’ I don’t get leg cramps anymore and can sleep peacefully.

Go back to the old formula!
Terrible change in product. I have been getting this for years and then all of sudden a change which I feel is not as effective, most importantly. Go back to the old formula!

Poor
The capsules have changed color. Please change back. The new ones no longer are effective. I've used the previous ones for several years and never a problem but the new color ones leave me feeling bloated and constipated.

Vitamins to replicate Multi Pak
This is one of the various vitamins that I purchased to replicate the MULTI-VITAMIN packs that were discontinued by Nature Made couple of years ago. I had been taking these vitamins throughout my military career and afterwards, they were great and they kept me healthy i believe!

feel ripped off
The product is good but the quantity is bull crap. I bought 150 count but the bottle can hold 150 more.
1 reply from Nature Made team - 9 months ago
We strive to deliver the highest quality packaging possible for our customers. Several of our products use the same size container to help maintain uniformity of the bottles so that it is easier to find the product you are looking for on the shelf. In some instances, this results in bottles that are not completely full. Please note that our bottles can be recycled. We appreciate your feedback and will share your comments with our product team to see what improvements can be made.
