Customers praised this magnesium supplement for improving sleep quality and relieving leg cramps. Many noted "no more leg cramps" and feeling "clear-headed and rested." The blend of three magnesiums is gentle on digestion. However, one customer was disappointed it lacks L-Threonate. Overall highly rated for effectiveness and quality.

  • Super Great, no more leg cramps
  • I stay asleep and I wake in the morning feeling refreshed!
  • A perfect combination of three kinds of magnesium

I ordered your product according to the front label an neglected to read the ingredients till I received your product. Magnesium Complete is not complete without “L-Threonate”. I’ve already ordered the magnesium I need from another’s supplier.

I completely understand your point, and you are entirely right that Magnesium L-Threonate is the gold standard for crossing the blood-brain barrier to support memory, focus, and sleep. The reason this specific formula is called a 'Magnesium Complete' complex is because it provides 100% full-spectrum support for the rest of your physical body. It balances forms like Oxide, Citrate, and Aspartate to maximize absorption in your muscles, heart, digestive tract, and cellular energy systems. Because Magnesium L-Threonate was only discovered and commercialized relatively recently (patented in 2009), traditional 'complete' complexes focus heavily on structural and systemic body health. If your primary goal is sharp cognitive focus or direct brain support, pairing this with a standalone L-Threonate or switching to a modern neurological blend would be the perfect path forward

A Good, Balanced Product

I have taken other calcium products before, but they were one magnesium alone. I found that the balance of these three magnesiums are really beneficial. We live in an area short on minerals. I have also discovered that Magnesium Complete helps me to sleep better than the melatonin I was taking. I asked my daughter to try this and she is getting the same results.

Agreeably Complete

I have tried other magnsium combinations that have left my stomach upset. Another brand with multiple magnesuims that I used led to a lot of upset despite taking one-fourth of the recommended dosage. Lifesource's Magnesium Complete is not only agreeable to my digestive system, but a perfect combination of three kinds of magnesium. Each day I am confident that I am receiving exactly the formula that my body needs, plus it helps me to sleep at night when taken an hour before bedtime. I highly recommend this product.

I started taking Magnesium about 2 weeks ago. For about 3 years I've been having trouble sleeping all night without waking up in the middle of the night. Magnesium does not make me sleepy, but once I am asleep, I stay asleep and I wake in the morning feeling refreshed!
As we age, good quality sleep becomes very important! Thank you Lifesource!
