Alpha Lipoic Acid
Alpha Lipoic Acid (ALA / R-ALA)
Universal antioxidant that works in both water and fat, supporting blood sugar control, nerve health, and cellular energy.
Alpha Lipoic Acid is a unique antioxidant that's both water and fat-soluble, allowing it to work throughout the body. It's produced naturally but levels decline with age. Research shows benefits for blood sugar regulation, diabetic neuropathy, and as a general antioxidant. Also regenerates other antioxidants like vitamins C and E.
Mechanisms of Action
Universal Antioxidant
Works in both water and fat environments
Glucose Uptake
Enhances insulin sensitivity
Mitochondrial Cofactor
Essential for cellular energy production
Recommended Dose
300-600mg
Optimal Timing
- On empty stomach for best absorption
- 30-60 minutes before meals
Can be taken without food
Best Form
R-Alpha Lipoic Acid (R-ALA) — the natural form
Alternatives: Racemic ALA (R/S mix), Na-R-ALA (stabilized R-ALA)
R-ALA is the biologically active form. Racemic ALA contains 50% R and 50% S forms. Na-R-ALA is more stable.
Duration
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Food reduces absorption. R-ALA form is more bioavailable than racemic ALA. May cause blood sugar to drop if taken with diabetes medications.

Kohandel Gargari O et al. • JAMA network open (2024)
“In this network meta-analysis of randomized clinical trials, topiramate and pregabalin were associated with reduction in headache frequency and intensity.”
Key Findings:
- Compared with placebo, pregabalin (ratio of means [RoM], 0.38; 95% CI, 0.18-0.79) and topiramate with vitamin D3 (RoM, 0.44; 95% CI, 0.30-0.65) were associated with reduction in migraine frequency.
- However, no treatments were associated with significant improvements in quality of life or reduction of the duration of migraine attacks.
- Adverse events were higher with amitriptyline (RR, 3.81; 95% CI, 1.41-10.32), topiramate (RR, 4.34; 95% CI, 1.60-11.75), and valproate (RR, 5.93; 95% CI, 1.93-18.23) compared with placebo.

“The use of ALA to prevent neurological symptoms should be further researched.”
Key Findings:
- ALA treatment produced favorable results for TSS (a dose-related trend was observed), NDS, and the global satisfaction score.
- For VAS, VPT, NIS-LL, and NCS results, ALA did not produce favorable results.
- The use of ALA to prevent neurological symptoms should be further researched.

“The use of certain dietary supplements has resulted in a significant decrease in migraine prophylaxis.”
Key Findings:
- In adults, compared with placebo, these supplements did not significantly affect other outcomes, and omega-3 supplementation did not yield a statistically significant reduction in any of these outcomes.
- The use of certain dietary supplements has resulted in a significant decrease in migraine prophylaxis.
- Further clinical trials of high quality appear to be beneficial.
Michaelsen MP et al. • Nutrients (2025)
“This study found no convincing evidence of an effect of any dietary supplements on male infertility.”
Key Findings:
- This study found no convincing evidence of an effect of any dietary supplements on male infertility.
- Larger and more well-conducted randomized controlled trials focusing on specific supplements and considering pregnancy outcomes are needed.
- Further research warranted to confirm findings
Sharifi-Zahabi E et al. • International journal for vitamin and nutrition research. Internationale Zeitschrift fur Vitamin- und Ernahrungsforschung. Journal international de vitaminologie et de nutrition (2024)
“ALA supplementation had no statistically significant effect on iron-related parameters.”
Key Findings:
- In subgroup analysis, ALA significantly increased hemoglobin in patients with hematological disorders (WMD = 1.23 g/dL; 95% CI: 1.00, 1.45 g/dL; I2 = 96.6%, p < 0.001) and in studies with durations longer than 8 weeks (WMD = 1.03 g/dL; 95% CI: 0.82, 1.25 g/dL; I2 = 96.5%, p = 0.02).
- ALA supplementation had no statistically significant effect on iron-related parameters.
- Further research warranted to confirm findings
