Alpha Lipoic Acid

Alpha lipoic acid (ALA) is a powerful antioxidant that safeguards each of the cells in our body, supporting longevity by reducing oxidative stress and protecting against cellular damage. Research shows alpha lipoic acid protects against age-related health decline of the heart, brain and skin.

  • Supports cellular health by reducing oxidative stress
  • Promotes energy production by supporting mitochondrial health
  • Normalizes blood sugar levels by improving insulin sensitivity
  • Protects the heart from free radical damage
  • Enhances cognitive health by protecting neurons from oxidative damage
  • Improves skin health by aiding in collagen synthesis

Research-Supported Benefits:

Supports Cellular Health. Alpha lipoic acid (ALA) functions as a powerful antioxidant, protecting each of the cells in our body from oxidative damage. (1) Studies show that oxidative damage is a key contributor to age-related health decline and decreased longevity. (2) ALA further supports cellular health by aiding in mitochondrial biogenesis (the creation of new mitochondria), which is critical for ATP (cellular energy) production. (3)

Regulates Blood Sugar. Research shows alpha lipoic acid exhibits blood-sugar regulating effects by increasing the uptake of glucose into cells and increasing insulin sensitivity. (4) A 2022 meta-analysis of 16 randomized controlled trials concluded alpha lipoic acid supplementation significantly reduces fasting blood glucose and Hemoglobin A1C. (5)

Enhances Heart Health. By reducing oxidative stress, alpha lipoic acid offers protection against age-related decline of heart health. A 2022 randomized controlled trial involving 46 participants found that 12 weeks of alpha lipoic acid supplementation offers additional cardio-protection by significantly reducing triglycerides and total cholesterol. (6)

Promotes Cognitive Health. Research shows that oxidative stress contributes to many of the symptoms of brain aging, including cognitive dysfunction and reduced memory. (7) Animal studies indicate alpha lipoic acid has neuroprotective effects by reducing markers of oxidative stress in the brain. (8)

Improves Skin Health. A key contributor to skin aging is the decline in collagen production that occurs after age 40. Alpha lipoic acid supports healthy collagen synthesis by aiding in the recycling of vitamin C, which is a critical nutrient that promotes collagen production within the body. The antioxidant effects of alpha lipoic acid offer further support for skin health by protecting against oxidative damage of skin cells from environmental factors.

  • Alpha lipoic acid (ALA) is a naturally occurring compound that functions as a powerful antioxidant in the body.
  • It is both water-soluble and fat-soluble, allowing it to work in various cellular environments.
  • ALA is produced in small amounts within the human body and can also be obtained from food sources such as spinach, broccoli, brussels sprouts and organ and red meats.
  • Due to its antioxidant effects, alpha lipoic acid decreases levels of oxidative stress and reduces symptoms of age-related health decline of the heart, brain, and skin.
  • Studies show alpha lipoic aids in blood sugar regulation, which is critical for longevity and cellular health.
  • ALA further improves cellular health by supporting ATP production and mitochondrial biogenesis.

Frequently asked questions

Some studies suggest the bioavailability of alpha lipoic acid is diminished when taken with food, so it is commonly recommended to take alpha lipoic acid either 30 minutes before, or 2 hours after a meal. (10)
