The interaction in detail
| Pair | Alpha-lipoic acid and Insulin |
|---|---|
| Type | Nutrient–drug interaction |
| Severity | Moderate |
| Required spacing | None specified |
| Onset | At the time of dosing |
Mechanism
Alpha-lipoic acid improves insulin-stimulated glucose uptake and can lower blood glucose, adding to insulin.
What to do
Monitor glucose closely and anticipate a possible dose reduction.
How to fit both into one day
Alpha-lipoic acid
morningempty stomach
Alpha-lipoic acid absorbs better on an empty stomach. Take it 30 minutes before breakfast if glucose control is the goal.
Putting Alpha-lipoic acid in the morning and Insulin in the evening satisfies the 0-hour separation without disrupting either one's absorption window.
