Analysis

NOW Tri-Amino is a supplement designed to provide a synergistic blend of three key amino acids: L-Arginine, L-Lysine, and L-Ornithine. L-Arginine is a precursor to nitric oxide, vital for healthy blood flow and cardiovascular function, which indirectly supports fitness and muscle gain by improving nutrient delivery. L-Lysine is an essential amino acid known for its role in protein synthesis, collagen formation (beneficial for skin and hair health), and immune system support, particularly against certain viruses. L-Ornithine, often paired with Arginine, assists in the urea cycle, helping to detoxify ammonia and potentially reduce fatigue during exercise. While the product aims to cover a broad spectrum of health benefits, the individual dosages (550mg Arginine, 450mg Lysine, 400mg Ornithine) are on the lower end for achieving significant therapeutic effects for specific goals, as higher doses are often used in clinical studies and recommended by nutritionists for targeted results. Online reviews generally reflect positive experiences for general wellness and mild improvements, but rarely describe dramatic results in any single area. The price per serving is competitive for a multi-amino blend, but more cost-effective options exist for higher doses of individual components.

Pros
  • Offers a convenient combination of three beneficial amino acids in one supplement.
  • L-Arginine supports cardiovascular health and blood flow through nitric oxide production.
  • L-Lysine contributes to immune function, collagen formation for skin and hair health.
  • L-Ornithine aids in ammonia detoxification, potentially supporting recovery.
  • Manufactured by NOW, a well-regarded brand known for quality and transparency.
Cons
  • Dosages of L-Arginine (550mg) and L-Ornithine (400mg) are relatively low for achieving significant performance or cardiovascular benefits.
  • The L-Lysine dose (450mg) is moderate for general support but often insufficient for specific antiviral protocols.
  • Consumers seeking high-impact results for a single goal might find more effective standalone or higher-dose products.
Warnings
  • Individuals with certain medical conditions, especially those affecting blood pressure or kidney function, should consult a healthcare professional before using arginine-containing supplements.
  • Pregnant or nursing women and individuals taking medications should exercise caution and seek medical advice.

Categories
Lysine 75.0
The 450mg L-Lysine dose provides a solid amount for daily maintenance, contributing to its roles in protein synthesis, collagen health, and immune support. For specific antiviral applications, especially for recurrent issues like cold sores, a higher therapeutic dosage is generally recommended, which this product doesn't provide in a single serving.
Arginine 70.0
The 550mg L-Arginine dose is moderate for general benefits but is significantly lower than amounts typically used for pronounced effects on nitric oxide production, athletic performance, or robust cardiovascular support. Many standalone arginine supplements offer higher concentrations per serving, making them more effective for targeted benefits.
Goals
Immunity 75.0
L-Lysine is well-recognized for its immune-modulating properties, particularly its effectiveness against the herpes simplex virus. The 450mg dose offers a good daily maintenance level for general immune support, although higher doses (1g+) are often recommended for acute immune challenges like cold sore outbreaks.
Cardiovascular Support 70.0
L-Arginine is a direct precursor to nitric oxide, which plays a crucial role in vasodilation and healthy blood flow, directly benefiting cardiovascular function. While 550mg is a lower dose compared to therapeutic levels, it still provides a beneficial contribution to cardiovascular health and circulation.
Skin Health 70.0
L-Lysine is a crucial component for the synthesis of collagen, which is essential for maintaining the structure, elasticity, and overall health of the skin. Supplementing with 450mg of L-Lysine can help support the body's natural collagen production, contributing to healthier skin.
