To solve this optimization problem, we first need to define the variables, objective function, and constraints using Gurobi's Python API.

### Problem Definition

The problem is to minimize the objective function:

\[ 4.24x_0 + 5.15x_1 + 8.7x_2 + 8.62x_3 + 9.04x_4 + 7.04x_5 \]

subject to various constraints.

### Variables

Let \( x_0, x_1, x_2, x_3, x_4, x_5 \) represent the milligrams of vitamin B6, B12, K, A, B7, and B3, respectively.

### Constraints

The constraints can be directly translated from the problem description. 

### Gurobi Code

```python
import gurobi as gp

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

# Define variables
x0 = m.addVar(lb=0, name="vitamin_B6", vtype=gp.GRB.CONTINUOUS)
x1 = m.addVar(lb=0, name="vitamin_B12", vtype=gp.GRB.CONTINUOUS)
x2 = m.addVar(lb=0, name="vitamin_K", vtype=gp.GRB.CONTINUOUS)
x3 = m.addVar(lb=0, name="vitamin_A", vtype=gp.GRB.CONTINUOUS)
x4 = m.addVar(lb=0, name="vitamin_B7", vtype=gp.GRB.CONTINUOUS)
x5 = m.addVar(lb=0, name="vitamin_B3", vtype=gp.GRB.CONTINUOUS)

# Objective function
m.setObjective(4.24*x0 + 5.15*x1 + 8.7*x2 + 8.62*x3 + 9.04*x4 + 7.04*x5, gp.GRB.MINIMIZE)
