Buying Guide: Choosing the Right NOW L-Tyrosine Supplement
When selecting an L-Tyrosine supplement, you need to consider more than just the price tag. Dosage, purity, and brand trust all play a role. Below we break down the most important factors to help you make an informed decision.
1. Dosage Strength: 500 mg vs. 750 mg
The most obvious difference between these two products is the amount of L-Tyrosine per capsule. The 500 mg version is a classic starting dose that works well for most people, especially if you are new to amino acid supplementation. It provides a gentle lift in mental alertness without overstimulation. The 750 mg option is better suited for those who have built some tolerance or need a more pronounced effect during high-stress periods. Think of it as a step up for demanding cognitive tasks. If you are unsure, starting with 500 mg and adjusting later is a safe strategy.
2. Purity and Certifications
Both formulations from NOW are pharmaceutical grade and free from common allergens. They are dairy free, egg free, made without gluten, non-GMO, nut free, and soy free. Each batch is evaluated in ISO/IEC accredited in-house laboratories for stability, potency, and product formulation. This level of quality assurance means you are getting a clean supplement without hidden fillers. For comparison, you can read our nootropics depot cognance review to see how another brand approaches purity standards.
3. Capsule Count and Convenience
The 500 mg bottle contains 120 capsules, while the 750 mg bottle holds 90 capsules. This difference affects how long each bottle lasts and how often you need to reorder. With 500 mg, you get 120 servings if you take one capsule per day. With 750 mg, you get 90 servings. If you prefer a higher dose but want fewer capsules to swallow, the 750 mg version is more convenient. Conversely, if you want flexibility to split doses or take smaller amounts, the 500 mg bottle offers more capsules per purchase.
4. Brand Reputation and History
NOW has been a trusted name in natural supplements since 1968. The company is family owned and employee owned, which fosters a strong commitment to quality. Their GMP certification means every manufacturing step is inspected, from raw material sourcing to final packaging. Buying from NOW gives you peace of mind that you are supporting a brand with decades of experience. For more product recommendations from reliable brands, visit our REVIEWS category page.
