What does the data say about L-Lysine 1000mg Free F... vs NOW Foods Taurine 1000mg?
These two products sit in completely different corners of the amino acid space. Solgar's L-Lysine 1000mg provides an essential amino acid — one your body cannot produce — specifically useful for collagen synthesis and, most notably, managing cold sore outbreaks by competing with arginine. NOW Foods Taurine 1000mg, on the other hand, is a conditionally essential amino acid associated with cardiovascular function, cellular hydration, and longer-term metabolic support. Both come in standard solid forms, though Solgar uses tablets (reportedly large ones) while NOW Foods opts for capsules, which tend to be easier to swallow.
If you suffer from recurring cold sores, Solgar is the obvious pick. At £13.00 for 50 tablets, it scores 80/100 overall with a notably high effectiveness score of 90/100, and reviewers back that up with real reports of reduced outbreak severity. NOW Foods suits someone with a longer game in mind — cardiovascular health, endurance support, or general longevity — and its 83/100 value score reflects strong cost-per-serving. Pricing isn't listed for NOW, which makes direct comparison tricky.
On credentials, NOW Foods has the edge: GMP certified, NPA A-rated facility, third-party tested. Solgar has no third-party certification noted here. Both appear well-tolerated, though NOW's taurine can cause mild stomach upset on an empty stomach.
Solgar's L-Lysine 1000mg receives unanimous 5-star ratings from 4 reviewers, with strong endorsement for cold sore management and immune support.
