From the various multivitamins I've tried to this day, this one is the best. I get very good energy levels, includes a B-100 and a high dose of C yet it is split in multiple pills. There are extra compounds for heart support and immune system improvement.
Elan Vital is the most comprehensive vitamin formula on the market. The only downside to the product is that I feel it contains a little bit too much DMSA per tablet. It's important to be under the care of a physician with regular blood monitoring if taking Succinic acid or Dmsa which is contained in the Elan Vital.
