Thorne Amino Complex

Pros

  • Complete EAA profile covering all nine essential amino acids with leucine-forward ratios aligned to muscle protein synthesis research
  • NSF Certified for Sport — independently verified for banned substances, making it safe for competitive and drug-tested athletes
  • Exceptionally clean formulation: stevia and fruit/vegetable juice only, no artificial sweeteners, colours, or preservatives
  • Reviewers consistently report tangible recovery benefits — faster reduction in muscle soreness and sustained energy through later sessions

Cons

  • Price is the most recurring complaint — 30 servings runs out fast for daily or twice-daily users and the cost is high relative to unflavoured EAA alternatives
  • Flavour divides opinion: a meaningful minority find it overly sweet or detect a slightly bitter, medicinal undertone
  • Leucine dose at 2000 mg per serving is effective but on the conservative end; athletes prioritising maximal MPS stimulation may prefer higher-leucine formulations
  • Tub size (228 g / 30 servings) feels small for the premium price, which limits accessibility for budget-conscious buyers

Best For

Recreational and competitive athletes prioritising clean, tested recovery supplements Drug-tested athletes requiring NSF Certified for Sport verification Consumers transitioning from BCAA-only products to a full EAA formula Those on allergen-restricted or plant-based diets (vegan, gluten-free, soy-free, dairy-free) Anyone who values ingredient transparency and dislikes artificial additives in their supplements

NOW Foods Taurine 1000mg

Pros

  • Exceptionally clean formula: free-form taurine with only three standard excipients (cellulose capsule, magnesium stearate, silica)
  • Strong manufacturing credentials: GMP certified, NPA A-rated facility, third-party tested
  • Excellent value — 100 servings per bottle at a competitive unit cost
  • Free from all major allergens (gluten, dairy, soy, eggs, nuts, shellfish) and fully vegan

Cons

  • Can cause mild stomach upset if taken on an empty stomach
  • Effects are subtle and slow-onset — at least one user reported needing weeks before noticing any change
  • 1000mg is at the lower end of doses used in cardiovascular and longevity research, where studies often use 2–6g per day
  • Very limited product-specific review data available; scoring leans heavily on ingredient and brand knowledge

Best For

Cardiovascular health and heart function support Athletes and gym-goers seeking a modest endurance and recovery aid Over 50s interested in longevity and cellular health research Vegans who get little dietary taurine (found almost exclusively in animal foods) Budget-conscious buyers wanting a third-party tested, no-frills amino acid supplement

What does the data say about Thorne Amino Complex vs NOW Foods Taurine 1000mg?

These two products share a category name but serve entirely different purposes. Thorne Amino Complex delivers 5.14g of all nine essential amino acids per serving in powder form, with a leucine-forward ratio specifically designed to trigger muscle protein synthesis. NOW Foods Taurine 1000mg is a single-ingredient capsule providing one amino acid — taurine — which plays a supporting role in cardiovascular function and cellular hydration rather than muscle building directly.

Thorne (80/100, £42.99) suits athletes who want a complete EAA formula they can trust in competition. The NSF Certified for Sport verification matters if you're subject to drug testing, and the clean sweetener profile (stevia and fruit juice only) appeals to those avoiding artificial additives. The downside is cost — 30 servings disappears quickly for daily users, and value scores reflect that at 62/100. NOW Foods Taurine (74/100) scores 83/100 for value with 100 capsules per bottle, making it far more accessible budget-wise.

Practically, Thorne's flavour divides opinion — some find it overly sweet. NOW's capsules are straightforward but should be taken with food to avoid mild stomach upset. Both are third-party tested, which is reassuring at either price point.
