Antioxidants
Alpha-Lipoic Acid
Also known as: ALA, thioctic acid, lipoic acid
An antioxidant involved in mitochondrial energy metabolism. IV ALA is used in some countries for diabetic nerve pain; wellness energy drips are a different, unproven use.

What the evidence supports
| Use | Evidence |
|---|---|
| Diabetic peripheral neuropathy (studied IV and oral regimens) | Emerging |
| Wellness energy, brain, or blood-sugar 'optimization' drips | Unproven |
Common side effects
- Nausea
- Skin rash or itching
- Low blood sugar (especially with diabetes medications)
Who should be cautious or avoid this
- Diabetes medications — can add to hypoglycemia risk
- Thiamine (B1) deficiency — ALA can worsen it; alcohol use disorder needs B1 addressed first
- Thyroid medication timing
What it is
Alpha-lipoic acid (ALA, thioctic acid) is an antioxidant your mitochondria use when turning carbohydrate into energy. It is both water- and fat-soluble, which is why supplement marketing calls it “universal.” That is chemistry, not a clinical result.
Why it’s used in IV therapy
Appears on energy, brain, and blood-sugar-themed drips. In some European protocols, IV ALA has been studied for diabetic nerve pain — a specific medical use, not a wellness add-on.
What the evidence says
Some randomized trials of IV or high-dose oral ALA for diabetic neuropathy showed modest symptom improvement; it is not a U.S. first-line standard, so the evidence level is emerging, not established. Using ALA in a healthy person for energy, “brain health,” or metabolic optimization has not been shown to work.
Side effects and cautions
Nausea and rash occur. ALA can lower blood glucose — people on insulin or other diabetes drugs need a plan, not a surprise. It can also worsen thiamine deficiency, so it does not belong in a hangover bag unless B1 status is addressed. Not the same thing as a Lipo-B (MIC) shot — the names get confused on menus.
