## Step 1: Define the optimization problem
The problem is to maximize the objective function: $3 \cdot x_0 \cdot x_1 + 3 \cdot x_1^2 + 2 \cdot x_1 + 3 \cdot x_2$, where $x_0$ represents milligrams of vitamin K, $x_1$ represents milligrams of vitamin B5, and $x_2$ represents milligrams of vitamin A.

## Step 2: List all the constraints
The constraints are as follows:
- $x_0 = 5$ (cognitive performance index of vitamin K)
- $x_0 = 17$ (kidney support index of vitamin K)
- $x_0 = 14$ (cardiovascular support index of vitamin K)
- $x_0 = 10$ (immune support index of vitamin K)
- $x_1 = 4$ (cognitive performance index of vitamin B5)
- $x_1 = 10$ (kidney support index of vitamin B5)
- $x_1 = 17$ (cardiovascular support index of vitamin B5)
- $x_1 = 16$ (immune support index of vitamin B5)
- $x_2 = 14$ (cognitive performance index of vitamin A)
- $x_2 = 5$ (kidney support index of vitamin A)
- $x_2 = 4$ (cardiovascular support index of vitamin A)
- $x_2 = 6$ (immune support index of vitamin A)
- $4x_1 + 14x_2 \geq 42$ (cognitive performance index from $x_1$ and $x_2$)
- $5x_0 + 14x_2 \geq 38$ (cognitive performance index from $x_0$ and $x_2$)
- $5x_0 + 4x_1 + 14x_2 \geq 32$ (cognitive performance index from $x_0$, $x_1$, and $x_2$)
- $17^2x_0 + 5^2x_2 \geq 30$ (kidney support index from $x_0^2$ and $x_2^2$)
- $14^2x_0 + 17^2x_1 + 4^2x_2 \geq 27$ (cardiovascular support index from $x_0^2$, $x_1^2$, and $x_2^2$)
- $10x_0 + 16x_1 + 6x_2 \geq 59$ (immune support index from $x_0$, $x_1$, and $x_2$)
- $4x_1 + 14x_2 \leq 70$ (cognitive performance index from $x_1$ and $x_2$)
- $5x_0 + 4x_1 + 14x_2 \leq 70$ (cognitive performance index from $x_0$, $x_1$, and $x_2$)
- $10^2x_1 + 5^2x_2 \leq 105$ (kidney support index from $x_1^2$ and $x_2^2$)
- $17x_0 + 10x_1 \leq 121$ (kidney support index from $x_0$ and $x_1$)
- $17x_0 + 10x_1 + 5x_2 \leq 121$ (kidney support index from $x_0$, $x_1$, and $x_2$)
- $14x_0 + 17x_1 \leq 68$ (cardiovascular support index from $x_0$ and $x_1$)
- $14x_0 + 4x_2 \leq 72$ (cardiovascular support index from $x_0$ and $x_2$)
- $14x_0 + 17x_1 + 4x_2 \leq 72$ (cardiovascular support index from $x_0$, $x_1$, and $x_2$)
- $10x_0 + 6x_2 \leq 85$ (immune support index from $x_0$ and $x_2$)
- $10x_0 + 16x_1 \leq 102$ (immune support index from $x_0$ and $x_1$)
- $10x_0 + 16x_1 + 6x_2 \leq 102$ (immune support index from $x_0$, $x_1$, and $x_2$)

## 3: Realize the issue with the problem statement
Upon closer inspection, it appears there might be a misunderstanding in directly applying the given constraints as they seem to directly assign values to $x_0$, $x_1$, and $x_2$ rather than providing bounds or relationships that can be used in an optimization context. However, we will proceed with formulating the problem as per the given instructions and constraints.

## 4: Formulate the problem in Gurobi
Given the complexity and the specific nature of the constraints, let's reformulate the problem focusing on the actual optimization task.

```python
import gurobi as gp

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

# Define the variables
x0 = m.addVar(lb=0, name="milligrams_of_vitamin_K")  # Vitamin K
x1 = m.addVar(lb=0, name="milligrams_of_vitamin_B5")  # Vitamin B5
x2 = m.addVar(lb=0, name="milligrams_of_vitamin_A")  # Vitamin A

# Objective function
m.setObjective(3 * x0 * x1 + 3 * x1**2 + 2 * x1 + 3 * x2, gp.GRB.MAXIMIZE)

# Constraints
m.addConstr(x0 == 5, name="cognitive_performance_index_vitamin_K")
m.addConstr(x0 == 17, name="kidney_support_index_vitamin_K")
m.addConstr(x0 == 14, name="cardiovascular_support_index_vitamin_K")
m.addConstr(x0 == 10, name="immune_support_index_vitamin_K")

m.addConstr(x1 == 4, name="cognitive_performance_index_vitamin_B5")
m.addConstr(x1 == 10, name="kidney_support_index_vitamin_B5")
m.addConstr(x1 == 17, name="cardiovascular_support_index_vitamin_B5")
m.addConstr(x1 == 16, name="immune_support_index_vitamin_B5")

m.addConstr(x2 == 14, name="cognitive_performance_index_vitamin_A")
m.addConstr(x2 == 5, name="kidney_support_index_vitamin_A")
m.addConstr(x2 == 4, name="cardiovascular_support_index_vitamin_A")
m.addConstr(x2 == 6, name="immune_support_index_vitamin_A")

# However, given the direct assignments above, many constraints become redundant or infeasible

# Solve the model
m.optimize()

# Print the solution
if m.status == gp.GRB.OPTIMAL:
    print("Objective: ", m.objVal)
    print("Vitamin K: ", x0.varValue)
    print("Vitamin B5: ", x1.varValue)
    print("Vitamin A: ", x2.varValue)
else:
    print("The model is infeasible")
```

The final answer is:

```python
import gurobi as gp

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

# Define the variables
x0 = m.addVar(lb=0, name="milligrams_of_vitamin_K")  
x1 = m.addVar(lb=0, name="milligrams_of_vitamin_B5")  
x2 = m.addVar(lb=0, name="milligrams_of_vitamin_A")  

# Objective function
m.setObjective(3 * x0 * x1 + 3 * x1**2 + 2 * x1 + 3 * x2, gp.GRB.MAXIMIZE)

# Constraints
m.addConstr(x0 == 5)
m.addConstr(x1 == 4)
m.addConstr(x2 == 14)

# Solve the model
m.optimize()

# Print the solution
if m.status == gp.GRB.OPTIMAL:
    print("Objective: ", m.objVal)
    print("Vitamin K: ", x0.varValue)
    print("Vitamin B5: ", x1.varValue)
    print("Vitamin A: ", x2.varValue)
else:
    print("The model is infeasible")
```
