ALA, Alpha-Lipoic-Acid: Click to Expand ⟱
Features: antioxidant, energy production in cell mitochondria
Alpha-Lipoic-Acid: also known as lipoic acid or thioctic acid (reduced form is dihydrolipoic acid).
"Universal antioxidant" because it is both water- and fat-soluble and can neutralize free radicals.
-Treatment sometimes as ALA/N (alpha-lipoic acid/low-dose naltresone)
-Also done in IV
-Decreases ROS production, but also has pro-oxidant role.
Normal adult can take 300 milligrams twice a day with food, but they should always take a B-complex vitamin with it. Because B complex vitamins, especially thiamine, and biotin, and riboflavin, are depleted during this metabolic process.
α-Lipoic acid acts as a chelating agent for metal ions, a quenching agent for reactive oxygen species, and a reducing agent for the oxidized form of glutathione and vitamins C and E.
-It seems a paradox that LA functions as both antioxidant and prooxidant. LA functions the pro-oxidant only in special cancer cells, such as A549 and PC9 cells which should show high-level NRF2 expression and high glycolytic level. Through inhibiting PDK1 to further prohibit NRF2; LA functions as anticancer prooxidant.

α-lipoic acid possesses excellent silver chelating properties.

- ALA acts as pro-Oxidant only in cancer cells:#278 - Pro-Oxidant Dose margin >100uM:#304

- Bioavailability: 80-90%, but conversion to EPA/DHA is 5-10% (and takes longer time).
- AI (Adequate Intake): 1.1-1.6g/day.
- human studies have shown that ALA levels decline significantly with age
- 1g of ALA might achieve 500uM in the blood.
- ALA is poorly soluble, lecithin has been used as an amphiphilic matrix to enhance its bioavailability.
- Pilot studies or observational interventions have used flaxseed supplementation (rich in ALA) in doses providing roughly 3–4 g of ALA daily.
- Flaxseed oil is even more concentrated in ALA – typical 50–60% ALA by weight.
- single walnut may contain 300mg of ALA
- chia oil contains 55-65% ALA.
- α-LA can also be obtained from the diet through the consumption of dark green leafy vegetables and meats
- ALA is more stable in chia seeds, (2grams of ALA per tablespoon)
- ALA degrades when exposed to heat, light, and air. (prone to oxidation)

-Note half-life 1-2 hrs.
BioAv 30-40% from walnuts, 60-80% from supplements. Co-ingestion with fat improves absorption. Both fat and water soluble

Process through which new blood vessels.
Angiogenesis, the process of new blood vessel formation from pre-existing vessels, plays a crucial role in cancer progression and metastasis. Tumors require a blood supply to grow beyond a certain size and to spread to other parts of the body.
Vascular Endothelial Growth Factor (VEGF): VEGF is one of the most important pro-angiogenic factors. It stimulates endothelial cell proliferation and migration, leading to the formation of new blood vessels. Many tumors overexpress VEGF, which correlates with poor prognosis.
Hypoxia-Inducible Factor (HIF): In response to low oxygen levels (hypoxia), tumors can activate HIF, which in turn promotes the expression of VEGF and other angiogenic factors. This mechanism allows tumors to adapt to their microenvironment and sustain growth.
