B- Goal FitD- Strength of SupportD CoverageB Formula Quality

B-vitamins, iodine, and trace minerals are provided in this multivitamin tailored for older adults. It includes secondary support from lycopene and lutein for general health maintenance.

While it provides essential cofactors, the B-vitamin doses are much lower than high-potency alternatives specifically designed for energy. It appears aligned for basic nutritional maintenance rather than a focused vitality protocol.
