The Promise

What this is — stabilized R‑lipoic antioxidant

A stabilized R‑lipoic acid supplement delivering a bioavailable antioxidant form.*

Active ingredient and dose

Each vegetable capsule provides 100 mg of actual R‑lipoic acid delivered as 143 mg of sodium R‑alpha‑lipoic acid.

Stabilized, bioavailable form*

This uses a sodium R‑alpha‑lipoic acid form that resists heat‑related polymerization and remains stable during storage.

Dual‑soluble antioxidant

R‑lipoic acid in this formula is both water‑ and fat‑soluble, allowing activity throughout the body’s tissues.

Hypoallergenic, vegetarian delivery

Capsules are vegetarian with hypoallergenic plant fiber (pine cellulose) and minimal added ingredients.

Why It Works

Why this formulation matters — specific formulation facts

Key formulation details that affect absorption, stability, and composition.*

01

Actual R‑lipoic content vs precursor

The product supplies 100 mg of the natural R isomer per capsule from 143 mg of the sodium R‑alpha‑lipoic precursor.

02

Sodium contribution noted

Each capsule contains 14 mg of sodium originating from the sodium R‑alpha‑lipoic and sodium carbonate components.

03

Stability advantage

The sodium R‑alpha‑lipoic form resists heat‑induced polymerization and remained stable in real‑time testing for 12 months.

04

R isomer benefits*

The natural R‑isomer is provided specifically because it offers enhanced cellular antioxidant activity compared with non‑isomeric forms.*

R–Lipoic Acid (stabilized) – This free radical scavenger is an antioxidant powerhouse. R-lipoic is both a water and fat soluble antioxidant, therefore is able to work anywhere in the body.Studies suggest that Lipoic acid assists with nerve health, and has been indicated to benefit those with diabetes and nerve disorders. Also known to be beneficial for protecting the liver and brain. This specific form of Lipoic acid is R-Lipoic, a stablized form that absorbs quicker and has been shown to be more effective as a cellular protectant.

What Is It?

Sodium R-alpha-lipoic acid is a highly bioavailable and stabilized form of R-lipoic acid. Regular R-lipoic acid is heat sensitive and may polymerize extensively, decreasing its absorption significantly. In real-time stability tests, sodium R-lipoic remained stable for 12 months. The natural R isomer of alpha-lipoic acid may provide enhanced antioxidant activity, energy production, and general metabolic function.*

Uses For R-lipoic acid (stabilized)

Nerve Health: In a recent in vitro study at the Buck Institute for Aging in California, R–lipoic acid moderated oxidative stress in neurons. A related study demonstrates the ability of R–lipoic acid to support memory tasks in animals by supporting mitochondrial function and protecting cells from free radicals.*

Glucose Metabolism: An animal study suggested that R–lipoic acid supported healthy glucose metabolism. Additional studies suggest that R-lipoic acid promotes glucose metabolism in skeletal muscle.*

Antioxidant Support: A University of California Berkeley study indicates that R–lipoic acid may be protective against age–related oxidative stress in the liver. Furthermore, a study at Oregon State University established a potential role for R–lipoic acid in protecting the heart from age–related oxidative stress.*

What Is The Source?

Pure Encapsulations R–Lipoic Acid (stabilized) delivers 100 mg of actual R–lipoic acid per capsule from 143 mg of synthetically derived sodium R-alpha-lipoic acid. Sodium is from sodium carbonate. Hypo-allergenic plant fiber is derived from pine cellulose.

Recommendations
