Magnesium Citrate

300 mg
Magnesium citrate is one of the most clinically studied forms, shown to offer significantly higher bioavailability than other forms of magnesium.* It acts as a gentle osmotic laxative, promoting smooth, comfortable digestion without harsh effects.* It also contributes to improved muscle relaxation and plays a role in over 600 metabolic reactions across the body.*

Magnesium Glycinate

300 mg
Magnesium glycinate is bonded to glycine an amino acid that helps regulate GABA, a key calming neurotransmitter.* This form is especially effective for nervous system relaxation and has been studied for its role in improving sleep quality and reducing serious mood issues.* One clinical trial reported rapid improvements in mood within 7 days using a combination of glycinate and taurinate forms.*

Magnesium Malate

300 mg
Formed with malic acid, this highly bioavailable form of magnesium supports ATP production and is often used to ease tension, headaches, and digestive irregularities.* Clinical studies in both humans and animals suggest that magnesium malate has superior absorption and stays active longer than many other forms making it ideal for daily use without digestive discomfort.*

Supported by Clinical Research

The Mineral Your Brain Can’t Live Without*

Doctor-Developed. Clinically Backed.*

Magnesium is one of the most important minerals in the human body, supporting 600+ enzymatic reactions.* It impacts how you think, sleep, digest, move, and manage stress yet over half of American adults don’t get enough from diet alone.*

When your magnesium levels are low, it can show up as:

  • Brain fog or mental fatigue
  • Trouble sleeping or relaxing at night
  • Sluggish digestion or occasional constipation
  • Mood swings, tension, or low energy

Smart Magnesium is doctor-formulated with the three most effective forms of magnesium malate, citrate, and glycinate to fuel the systems your brain and body rely on every day.*

Expert Reviews

“Smart Magnesium isn’t just another mineral supplement—it’s a brain-first formula that supports digestion, sleep, mood, and clarity in one highly absorbable blend.”

Daniel G. Amen, MD

Founder, BrainMD & Amen Clinics
"Smart Magnesium provides a highly absorbable form of magnesium that supports relaxation, muscle function, and overall brain health. I appreciate that this formula is gentle on digestion while delivering meaningful support for stress resilience and calm focus, making it an excellent daily choice for consumers seeking balance and wellness."

Dr. Nicole Avena

Chief Science Officer, BrainMD
"Most magnesium supplements barely get absorbed. Smart Magnesium actually gets into your body and brain. It features magnesium glycinate for full-body calm and magnesium threonate to support clear thinking, stress relief, and better sleep. You feel it where it counts. Because it’s not more magnesium… it’s smarter magnesium."

Reviews

This is perfect!!!

"I take medication and it causes restless legs syndrome. From a magnesium deficiency. It causes other deficiencies, too likely. I require high doses of magnesium. I was taking 2,000mg of magnesium threonate. But that was only about 145mg of elemental magnesium. Which was why I still suffered some from the restless legs. So I take double the dose of this magnesium!!! It works great!!! No restlessness!!!!"

Great stuff

"I really have liked this magnesium a lot. I've just started a second bottle and it's worked well for me. It's helped eliminate leg cramps and I love that I only take two tablets a day (which I take separately) instead of other mag tablets where you have to take up to 6 tablets a day."
