The brands are not near as important as getting a supplement regimen started and staying with it. It takes months for nerves to recover because the myelin sheath is slow growing/repairing. Strained nerve fibers can not heal until the myelin sheath has healed. The vitamins help the myelin sheath heal.

Just try to avoid the grocery store brands, One a Day, Centrum, etc. As mentioned GNC Mega Men/Women have good dosages. Do not double up on a lesser dose brand thinking it will make up. You may end up with too much of a trace element such as the metals.

The B-50 is important because it helps balance the B's but you should still add the B-12 and some B-6.
