NOW Supplements Alpha Lipoic Acid 600 mg Extra Strength delivers a potent dose of this key antioxidant in a single daily capsule. It is designed for adults looking to boost their body's natural defenses against oxidative stress, support healthy glucose metabolism, and maintain neural and cardiovascular health. This extra strength formula is ideal for those who already know the benefits of ALA and want a higher concentration without taking multiple pills.
The standout feature is the 600 mg per capsule, which is six times the amount found in standard strength versions. Alpha lipoic acid is unique because it works in both water and fat tissues, helping to recycle vitamins C and E and promoting the production of glutathione. This makes it a powerful ally in fighting free radicals and supporting cellular energy production.
NOW has packaged this supplement in 120 vegan capsules, making it a long lasting supply. The company has been family owned and operated since 1968, with manufacturing in the USA. The capsules are free from common allergens and are Non-GMO verified, appealing to health conscious consumers who prioritize clean ingredients.
However, the large size of the capsules may pose a challenge for those who have difficulty swallowing pills. Taking the supplement with a meal is recommended to avoid potential stomach discomfort. As with any supplement, those on medication or with medical conditions should consult a healthcare professional before use.
Overall, the NOW Alpha Lipoic Acid 600 mg Extra Strength offers excellent value for its potency and trusted brand reputation. If you need a high dose ALA supplement and don't mind large capsules, it is a solid choice for enhancing antioxidant defense and metabolic health.

Buying Guide
Dosage and Potency
When comparing PQQ and alpha lipoic acid, dosage matters significantly. ALA is often taken in higher amounts, with 600 mg per serving being common in products like PQQ vs CoQ10 supplements. PQQ, by contrast, is effective at much lower doses, typically 10 to 20 mg per day. Consider how much you are willing to take and whether you prefer a once-daily capsule or a split serving.
Form and Bioavailability
Alpha lipoic acid comes in both R-lipoic acid (the natural form) and a synthetic mixture. The synthetic form is more common and affordable but may be less bioavailable. PQQ is typically derived from fermentation and is well-absorbed. Look for third-party verification to ensure purity and potency, as with CoQ10 vs ubiquinol supplements.
Antioxidant Mechanisms
Both PQQ and ALA are antioxidants, but they work differently. ALA is both water- and fat-soluble, allowing it to neutralize free radicals in various cell compartments. It also regenerates other antioxidants like vitamins C and E. PQQ specifically supports mitochondrial biogenesis, helping your cells create more energy centers. This makes PQQ a strong choice for long-term energy, while ALA is excellent for acute oxidative stress.
Targeted Benefits
If your goal is improved glucose metabolism and nerve health, ALA is a well-researched option. For cognitive function and mitochondrial health, PQQ shines. Some users combine both for synergistic effects, but always consult a healthcare provider. For more on energy support for aging men, check our guide on ubiquinol vs CoQ10 for men over 50.
Final Thoughts
Choosing between PQQ and alpha lipoic acid depends on your primary health focus. For those targeting blood sugar balance and antioxidant protection, NOW Supplements, Alpha Lipoic Acid 600 mg offers a reliable, extra-strength option. If you prioritize mitochondrial energy and cognitive support, Nutricost Alpha Lipoic Acid (600mg) 120 Capsules provides excellent value and quality. Both are strong choices for men seeking vitality in 2026.
