Buying Guide: What to Look for in an L-Tyrosine Supplement
Dosage and Serving Size
Most studies use 500 to 1,000 mg per serving. If you’re new to L-tyrosine, start with 500 mg to assess tolerance. Look for a formula that clearly states the amount per capsule. For example, Double Wood provides 500 mg per capsule, while NOW offers both 500 mg and 750 mg options.
Consider your daily routine. A 1,000 mg dose may be ideal for intense focus sessions, while lower doses work for everyday support. Also check the total servings, not just the bottle size.
Purity and Third-Party Certification
Quality matters when it comes to amino acid supplements. Look for products that are non-GMO, gluten-free, and free from unnecessary fillers. Brands like NOW are known for their GMP quality assurance, which includes rigorous in-house analysis.
Double Wood emphasizes manufacturing in the USA with globally sourced ingredients. They also conduct heavy metal screening. Third-party certification adds another layer of trust, so choose brands that publish these details.
