Gentle and effective

Very helpful for constipation but very gently so. I would take one at night before bed and it really helped to soften otherwise painful bathroom visits. Read more

Consistently a solid product.

I have been purchasing this product for over a year now, which is always as expected. I have issues finding this type of Magnesium as this dosage from a single brand consistently in stores, so being able to order from Ruby via Amazon has been ideal. I have multiple comorbidities, and I have been advised by my medical team that adding 400mg 1/day might help. I have mainly noticed that my migraines are less frequent, which is amazing. I tend to have some digestive issues with other brands, but with Ruby, I have none of these issues. It is a great product with a good price point and is consistently available. This is my go-to for Magnesium supplements. Read more

Works great! I was someone who would get really bad migraines multiples times a month for years. I started taking this supplement in December of 2024 and I have only had 1 migraine since!! Read more

Fixed months of painful, irregular constipation!

Several months spent seeing a GI specialist and trying every possible softener, fiber, laxative, and medication, with no success. Out of desperation, I try this magnesium supplement that a friend’s mom uses. I take double the dose and within a week the constipation and pain is over! Every movement is soft, like it should be! I’m still irregular, but no longer experiencing painful blockage and bloody stools!! Read more
