Recommended by my doctor-hard to find gluconate

iherb is one of only two websites where I can find Magnesium Gluconate, which is what my doctor prescribed years ago and so I've been a customer of iherb for years. Product is always available and price is better than competitor. iherb has become my "go to" website for this as well as several others of my favorites when ordering.

⭐️⭐️⭐️⭐️⭐️ Mason Natural Magnesium Gluconate – Gentle Mineral for Sleep, Nerves, Hormones Review: This bottle is massive value — 333mg per tablet, and it lasts for months. The gluconate form is one of the gentlest magnesium types available — no GI upset or laxative effect like citrate or oxide. Tablets are a bit large, but easy to break in half. What I love is how calming and clean this feels. Taken at night, it promotes deeper sleep, reduces muscle tension, and helps you wake up less groggy. It’s also crucial for nervous system regulation, stress resilience, and hormone balance — especially testosterone and cortisol control. It stacks perfectly with glycine, taurine, melatonin, B6 (P5P), and even red light therapy for a complete night-time reset. Helps repair the CNS, calm the mind, and regulate circadian rhythms. Packaging is strong, tablets are smooth-pressed, and for the price per mg — it’s one of the best magnesium options out there for long-term health and recovery.

Good for sensitive digestive systems

This particular form of magnesium was recommended by a doctor for muscle cramps. I am not sure it's working for that but it is easier that other forms of magnesium on the digestive system. The product seems good quality, the tablets are about 13mm in diameter and are pretty flat so they can be swallowed fairly easily. No funny ingredients added it's another plus.

If taken after dinner, my leg muscles are active, keep on moving. I changed after lunch meal and disappeared. It improves my joints strength. No taste.

One of my Favorite Types of Magnesium

Great quality magnesium for an affordable price. It’s hard to find mg in the glunonate form but I started to look for it after I noticed that my mother’s doctor prescribed the gluconate form to her for her deficiency. It gives me an even calm. It’s something that I notice about 3 days into taking it. It’s not immediate but it’s there and noticeable after a bit. Another benefit is that I think it helps with joint and muscle pain. It makes delayed muscle onset pain a little less painful.

I bought this specifically because I needed to split the tabs into am/pm doses. The photos show bottles with tablets that have a pill-splitting ridge, but the product I received has the tablets smooth all over without a splitting ridge. Makes splitting a bit harder and it's very crumbly/powdery. That one complaint aside, this is working fine for me.

Great magnesium; some tablets crumble

This is my favorite type of absorbable magnesium that doesn't mess with the GI system, and it's a great price per unit, but some of the tablets in some bottles flake or split. They're still fine when in pieces, but harder to swallow.
