Expensive but Effective
MagSRT provides a higher dose than other available slow release formulas, and avoids the digestive distress that can be associated with regular release versions. However, given the cost, I would not recommend this as a first line magnesium supplement - try a regular release version, then a lower dose slow release if needed, and use this only if you require both the slow release and the higher dose.<br /><br />This version of MagSrt also provides B vitamin supplementation (B6, B12, Folate), which they say enhances absorption of the magnesium. The evidence for this is quite thin - some limited in vitro studies, but no in vivo human trials with positive results that I'm aware of. That said, there's no particular problem with the B vitamins being in the mix, except you may be taking something you don't need. Jigsaw does offer a B vitamin free version (MagSRT B Free), although the cost is the same.<br /><br />The pills are large, but not absurd (as some supplements can be), and have a uniquely smooth coating that makes them easy to get down. They have no particular odor or taste and no aftertaste. They can be split cleanly with a pill cutter, although I don't know what impact this has on absorption.<br /><br />Four stars for quality, one off because of the cost. A years worth, at the recommended dose (4 pills/day) is over $250.
