Why you take it

The one outcome you want to change
How you will know, and how often you will record it

Before you add the next product

  • I have the full Supplement Facts panel for every bottle, including herbs and vitamins
  • I counted what I actually take, not the serving size on the front of the label
  • The clinician who manages my warfarin, other blood thinner, diabetes medicine or cancer treatment knows about it
  • I am adding only one product this time, and I wrote down its start date
  • I am not changing any prescription dose to make room for a supplement

What the sources on this page say

  • In an 80-person trial, LDL cholesterol rose 17.1 mg/dL on pterostilbene alone over 6 to 8 weeks; the grape-extract combination did not show the rise.[1]
  • Vitamins, supplements and herbal products can raise bleeding risk with warfarin, so tell your doctor and pharmacist before taking any.[2]
  • Supplements taken with a cancer drug may change how it is absorbed, processed or removed from the body.[3]
  • If side effects start, stop the supplement and contact your health care provider.[4]

On warfarin, call your doctor immediately for

  • Bleeding that won't stop, nosebleeds, bleeding gums, easy bruising, or coughing or vomiting blood.[2]

For the pharmacist

  1. Do any two of my products contain the same B3 form, or more than one NAD+ precursor?
  2. Does any added ingredient matter for my prescriptions?
  3. If I keep a blend with pterostilbene, should my clinician recheck my cholesterol?
  4. Which product would you drop first if I want fewer pills?
