MagSRT® B-Free, 240 Tablets

Jigsaw’s MagSRT B-Free is one of the best magnesium supplements on the market, especially for those who are sensitive to other forms. It uses a sustained-release delivery system to ensure steady absorption, reducing the risk of loose stools or sudden spikes. The “B-Free” version contains no added B vitamins, which is great if you’re managing methylation issues or already supplementing B-complex separately. I noticed improved sleep quality, muscle recovery, and mood stability within a week. Tablets are large, but manageable. This is a premium product for chronic magnesium users looking for stable, long-term support — especially for sleep, adrenal health, and stress.

As someone with a complex debilitating illness that needs magnesium, I take 1/2 a pill every couple/few hours starting from my waking time until evening. I had the worst leg cramps every morning until I started doing this. I also use other magnesium but they never stopped the leg cramps.

I bought this MagSRT B-Free because it uses a sustained-release delivery system to ensure steady absorption. I do not require any added Vitamin B to improve its bioavailability as I am regularly taking the Jigsaw Vitamin B complex. So far no side effect!

The best magnesium for better Health. Good natural ingredient. Good size. Use All our family. Good quality. Good for muscle, natural mineral. Good Taste. Hormone. Sleep. Joint Benefit Package

I really like this product as it has quality ingredients at a reasonable price point but I won't continue taking these due to the ongoing cost.

Since magnesium is an essential mineral for the body and daily diet does not always provide the necessary amount, a good option is to supplement with this well-absorbed form. I take 4 tablets a day in the morning and evening.

It's expensive, but worth the money. Thanks to its slow-release formula, it doesn't cause intestinal problems. My magnesium levels have increased, according to my tests. My sleep has become deeper, and I have more energy during the day. I have a lot of vitamin B12 – over 1000 units. The B-Free formula is just what I need.

I tried Jigsaw brand magnesium malate normal one without sustain release works better for me Despite today I took 3 tablet = 375mg of elemental magnesium from this SRT but I still get twitching Whereby usually 200mg from Jigsaw regular brand should have helped me

Great quality and ingredients. The size is good, easy to take. I take it for the last 1.5 years and I feel the benefits. My sleep improved, no more muscle cramps and is very good for joint pain. The taste is normal, no difficulty taking it at all.

MagSRT has been a game-changer for my restless legs and sleep issues—I finally wake up feeling rested! The time-release formula means no sudden bathroom trips at 3 AM (huge plus). Even my partner noticed I’m less irritable, probably because I’m actually sleeping now. Worth every penny for the quality!
