Deductable Medical Expense Questions

In the info I found, it's hard to tell if all these would qualify.

Can the following medical expenses be deducted?

1. My wife is in a medical weight loss program at Kaiser. Can what she pays them for the program and food be deducted?

2. In Dec. 2016 my wife had knee surgery. Throughout 2017, she paid a naturopathic doctor for prolozone injections to aid in healing and cartilage regeneration. Can this expense be deducted?

3. Related to the knee, we spent a lot of money on things like supplements (collagen etc.), excercise and walking aids, special pillows etc. Can these be deducted?

4. Copays for doctor visits (Kaiser), dentist, orthodontist and oral surgery?

5. Prescriptions?

6. Cord blood banking/storage?

Thanks very much!
