What does the data say about N-Acetyl Cysteine 600m... vs Milk Thistle Detox Com...?

Solgar's NAC is a single-ingredient capsule delivering 600mg of free-form N-Acetyl Cysteine — a clinically studied dose used across liver support and respiratory research. The N2 Natural Nutrition Milk Thistle complex takes a broader approach, combining milk thistle extract (at a concentrated 38:1 ratio equating to 6840mg), artichoke, choline, NAC, B vitamins, selenium, and burdock in one capsule. Solgar scores 80/100 at £25.20; the N2 product scores 74/100 at £16.95.

If you want targeted NAC therapy — for glutathione production, liver detox support, or managing respiratory mucus — Solgar's standalone formula is the better pick. The dose is precise and the free-form absorption is well-regarded. It suits vegans and those who prefer knowing exactly what they're getting. The N2 complex suits someone coming off a period of poor diet or alcohol who wants broad liver and digestive support without buying five separate supplements. The £16.95 price makes it accessible for regular use.

Practically, Solgar's NAC has a notable sulphurous smell — keep it refrigerated. The N2 capsules are reportedly easy to swallow and tasteless.

N-Acetyl Cysteine 600mg Free Form 60 Vegi Capsules Winner 80.0/100

Solgar's NAC 600mg delivers N-Acetyl Cysteine in free-form for improved bioavailability — a well-researched glutathione precursor with strong science behind liver detoxification, antioxidant defence, and mucolytic activity.
