Here's the Gurobi code to solve the optimization problem. The code defines the variables, objective function, and constraints based on the provided information. It then solves the model and prints the optimized solution if feasible, or indicates if the problem is infeasible.

```python
import gurobipy as gp

# Create a new model
m = gp.Model("vitamin_optimization")

# Create variables
vitamin_b4 = m.addVar(name="vitamin_b4", lb=0)
vitamin_e = m.addVar(name="vitamin_e", lb=0)
vitamin_b7 = m.addVar(name="vitamin_b7", lb=0)
potassium = m.addVar(name="potassium", lb=0)
vitamin_b9 = m.addVar(name="vitamin_b9", lb=0)
fat = m.addVar(name="fat", lb=0)

# Set objective function
m.setObjective(6.2 * vitamin_b4 + 7.92 * vitamin_e + 1.58 * vitamin_b7 + 4.02 * potassium + 4.17 * vitamin_b9 + 2.55 * fat, gp.GRB.MAXIMIZE)
