New Sun Alpha Lipoic Acid Review

Alpha lipoic acid is taken here at 500 mg a day, above the 100 mg that worked in some studies. The results for blood sugar are mixed. In 57 adults with type 2 diabetes, 300 mg a day for 8 weeks lowered fasting blood sugar and insulin resistance compared with placebo ^[1]. In pregnant women with diabetes of pregnancy, 100 mg a day ^[2] and 300 mg a day ^[3] for 8 weeks lowered fasting blood sugar. In 80 critically ill patients, 900 mg a day for 10 days lowered blood sugar and prevented a rise in insulin resistance ^[4]. However, the two largest and longest trials found no benefit. In 467 people with type 2 diabetes, 600 mg a day for 2 years left long-term blood sugar unchanged ^[5]. In 151 people with metabolic syndrome, 600 mg a day for one year did not change blood sugar or insulin, though it modestly lowered blood fats ^[6]. Overall, shorter and smaller trials suggest a benefit, but longer and larger trials do not confirm it. Animal and cell studies are never counted.

Alpha-lipoic acid, the main ingredient here, gets a mostly positive response, with five of the eight panelists who spoke about it recommending it, two staying neutral, and one who stopped. People take it as an antioxidant that recycles glutathione and vitamins C and E, for mitochondrial and energy support, for nerve problems such as peripheral neuropathy and ringing in the ears, and for blood sugar and insulin resistance. The doses given are 600 mg a day for ringing in the ear and for recovering smell after a viral infection (taken with food), four doses through the day for neuropathy, and 100 mg once a day for brain health. Common pairings are benfotiamine, L-carnitine, fish oil at breakfast, and carb cycling days. As for cautions, one panelist took it only on days of hard exertion so it would not blunt the body's own antioxidant production, one said it could trigger migraines in sensitive people when combined with sulfur-rich foods like eggs, and one stopped taking it for longevity because he saw too little evidence.

The tier of 5 treats alpha lipoic acid as shown not to work, but the studies disagree: several placebo-controlled trials lowered blood sugar while the two largest and longest found no change, which fits tier 4, and the written review summary describes other brands' capsules rather than New Sun. So it is graded Tier 4, as the studies disagree.

Combine with: For blood sugar support, ALA pairs well with chromium picolinate, berberine, magnesium, and cinnamon extract, which complement its effects on insulin sensitivity and glucose uptake. Benfotiamine and acetyl-L-carnitine are commonly stacked with it for nerve health. For the cholesterol goal specifically, consider adding agents with stronger evidence such as plant sterols/stanols, soluble fiber (psyllium), red yeast rice (with medical guidance), bergamot extract, or omega-3 fish oil for triglycerides. Other antioxidants such as vitamin C, vitamin E, and CoQ10 can support ALA's antioxidant role. Take ALA on an empty stomach for best absorption, and consult a healthcare provider if using diabetes or meds, as ALA may lower blood sugar further.
