Natural Factors Natural Factors - Alpha-Lipoic Acid w/ B1 & B2 - 600 mg, 60 vcap
Natural Factors Alpha-Lipoic Acid with B1 & B2 - Combines alpha-lipoic acid (ALA) with vitamins B1 and B2 for enhanced antioxidant and blood glucose support. Alpha-Lipoic Acid increases the body’s total antioxidant capacity to protect against oxidative damage to muscles, nerves, and other tissues throughout the body. It also supports healthy blood sugar control by enhancing glucose uptake into cells. Vitamins B1 and B2 are essential nutrients for the metabolism of carbohydrates, fats, and proteins into energy. By combining them with ALA, they help reduce the risk of vitamin B deficiencies associated with standalone ALA formulas.

Why people keep reordering it
- Year-round defense
- Daily support for a resilient immune response.
- Antioxidant support
- Helps protect cells from everyday oxidative stress.
- Tradition meets research
- Time-tested ingredients in clinically informed doses.
Best suited to: want the dose the research actually used, looking at ala for nerve comfort, watching blood sugar alongside diet changes, already taking ala on its own.
What the research supports
One capsule provides 600 mg of alpha-lipoic acid alongside 25 mg of thiamine and 2.5 mg of riboflavin. The bottle holds a two-month supply.
Studies use 600 mg of ALA a day.
- Nerve comfort (evidence: moderate, from randomized controlled trial, meta-analysis)
- ALA is thought to protect nerve tissue from oxidative stress that impairs signaling. Trials at 600 mg daily against placebo report real but modest drops in burning, tingling and numbness.
- Antioxidant capacity (evidence: moderate, from randomized controlled trial, meta-analysis)
- Lipoic acid both quenches free radicals itself and regenerates vitamin C, vitamin E and glutathione back to their active forms, so its effect shows up in markers well beyond lipoic acid itself.
- Glucose uptake (evidence: mixed, from randomized controlled trial, meta-analysis)
- ALA is thought to help cells respond to insulin so more glucose moves out of the blood and into tissue. Trials on oral ALA report modest changes in fasting glucose in some people and none in others.
- Energy (evidence: strong, from established nutrition science)
- Thiamine and riboflavin are required cofactors in the enzyme steps that turn carbohydrate and fat into usable energy. Running low on either can leave you eating enough but still feeling flat.

Is it right for you
Worth it if
- Want the dose the research actually used
- 600 mg in a single capsule matches the daily amount across the oral ALA trials, with no stacking of two or three capsules to get there.
- Looking at ALA for nerve comfort
- 600 mg daily is the amount used in the randomized trials that measured burning and tingling sensations in the hands and feet.
- Watching blood sugar alongside diet changes
- ALA is studied for how efficiently cells pull glucose in, and the label's own warning about low blood sugar signs tells you it does something measurable there.
- Already taking ALA on its own
- The thiamine and riboflavin cover the two vitamins that partner ALA inside the same enzyme complexes, which a standalone ALA capsule leaves out.
Look elsewhere if
- Anyone shopping for a B-complex
- This carries two of the eight B vitamins, and at 2.5 mg the riboflavin is barely above a day's requirement. Buy an actual B-complex if that is the goal.
- Someone who specifically wants R-lipoic acid
- A panel that reads plain alpha-lipoic acid means the racemic mix, so roughly half of the 600 mg is the R form. Look for sodium R-lipoate on the panel if you want R only.
- Only remembers pills mid-meal
- Food cuts ALA absorption by around 30 percent, so if dinner is the only slot this will realistically happen, a nutrient less fussy about timing is a better use of the money.
What to expect
Nothing you can feel in week one. The trials that measured changes in nerve sensation ran three weeks at the shortest and three months more often, so give it that long before deciding. If you get sweating, shakiness, chills or confusion, that is the blood sugar effect, and it means stop and speak to a practitioner.
How it compares
- Compared with a plain alpha-lipoic acid capsule with no B vitamins
- Same 600 mg of ALA, plus 25 mg of thiamine and 2.5 mg of riboflavin, which are the vitamins working beside lipoic acid in the pyruvate dehydrogenase complex. The tradeoff: You pay for two B vitamins a multivitamin may already be covering, and 2.5 mg of riboflavin is a token amount rather than a therapeutic one.
- Compared with R-lipoic acid or sodium R-lipoate
- This is the racemic form at a full 600 mg, which is the exact form and dose the human trial record actually sits on. The tradeoff: R-lipoic acid is the biologically active half and absorbs better per milligram, so you need less of it. It costs considerably more, and its own trial evidence is thinner than the pile behind plain 600 mg.
