## Step 1: Define the symbolic representation of the problem
The problem involves several variables: 
- milligrams of magnesium ('x0' or 'mg_magnesium')
- milligrams of vitamin B2 ('x1' or 'mg_vitamin_B2')
- milligrams of vitamin K ('x2' or 'mg_vitamin_K')
- milligrams of vitamin D ('x3' or 'mg_vitamin_D')
- grams of fiber ('x4' or 'g_fiber')
- milligrams of calcium ('x5' or 'mg_calcium')

## Step 2: Translate the objective function into algebraic terms
The objective function to minimize is: 
\[ 4x_0 + 3x_1 + 1x_2 + 1x_3 + 5x_4 + 6x_5 \]

    g_fiber = model.addVar(name="g_fiber", vtype=gurobi.GRB.INTEGER)
    mg_calcium = model.addVar(name="mg_calcium")

    # Objective function
    model.setObjective(4 * mg_magnesium + 3 * mg_vitamin_B2 + mg_vitamin_K + mg_vitamin_D + 5 * g_fiber + 6 * mg_calcium, gurobi.GRB.MINIMIZE)

    # Cardiovascular Support Index Constraints
    model.addConstr(7 * mg_magnesium + 3 * mg_vitamin_B2 + mg_vitamin_K + 3 * mg_vitamin_D + 9 * g_fiber + 10 * mg_calcium <= 128)
    model.addConstr(10 * mg_magnesium + 8 * mg_vitamin_B2 + 5 * mg_vitamin_K + 7 * mg_vitamin_D + 8 * g_fiber + 7 * mg_calcium <= 101)

    # Add more constraints...

    # Solve the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB_OPTIMAL:
        print("Objective: ", model.objval)
        print("Magnesium: ", mg_magnesium.varValue)

optimize()
