Product analysis

53 out of 100

Tri-Amino puts arginine, lysine and ornithine together for convenient combined supplementation. The unspecified arginine form makes the complete mixture harder to compare.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality30

Lysine and ornithine have identified forms, while arginine is unspecified. The information does not establish an absorption or quality advantage for the combination.

Ingredient Transparency81

The listed amounts are disclosed, making quantities easier to compare. Lysine and ornithine forms are named, while the arginine form remains unspecified.

Value For Money40

The full serving cost offers middle-range value for arginine and less favorable value for lysine. The convenience of combining them does not establish that either is especially inexpensive.

Customer Satisfaction89

Customer ratings are very positive across several thousand responses. The broad feedback gives an established picture of satisfaction, without proving a particular health benefit.

Product Focus40

The amino acids give the formula a clear ingredient theme. There is not enough goal-specific information to describe a dependable expected benefit.

85 Performance

L-Arginine Pure Powder

Best Naturals

A substantial arginine amount provides far more focused circulation and fitness support than the original's modest arginine dose. The powder omits lysine and ornithine, and full intake directions and excipient details are not supplied.

85 Performance

L-Lysine Pharmaceutical Grade

Swanson

The named pharmaceutical-grade lysine monohydrochloride offers a more specific form and a slightly higher lysine amount than the original. It is focused rather than complete, with no arginine or ornithine and no supplied purity or excipient details.

80 Performance

L-Arginine 3000 mg

Natrol

A performance-focused arginine amount provides much greater nitric-oxide pathway depth than the original. The three-tablet serving omits lysine and ornithine, and arginine can compound blood-pressure-lowering medicines.

86 Budget

L-Lysine 500 mg

Source Naturals

A much lower serving cost supplies slightly more lysine than the original in a simple, clearly identified hydrochloride form. Arginine and ornithine are absent, so it is a better budget choice only when lysine is the priority.

83 Budget

L-Arginine 1000 mg

21st Century

A much lower serving cost nearly doubles the original's arginine amount in a clearly identified hydrochloride form. Lysine and ornithine are omitted, and arginine may add to the blood-pressure-lowering effects of nitrates or antihypertensive medicines.

86 Budget

L-Lysine 1000 mg

AN Amazing Nutrition Amazing Formulas

A much lower recurring cost more than doubles the original's lysine amount for focused supplementation. The single-active tablet does not preserve arginine or ornithine, so it trades breadth for dose efficiency.

86 Value

L-Lysine 1000 mg

Solgar

A low serving cost and a meaningful lysine hydrochloride amount provide stronger focused value than the original's smaller lysine contribution. Arginine and ornithine are absent, so the benefit is limited to users prioritizing lysine.

84 Value

Arginine 1000 mg

Jarrow Formulas

A lower recurring cost nearly doubles the original's arginine amount in a clear hydrochloride form. The formula omits lysine and ornithine, and the dose remains modest for targeted circulation or fitness use.

86 Value

L-Lysine 500 mg

NOW

A very low serving cost provides a straightforward lysine amount that slightly exceeds the original's lysine dose. It offers better value for focused lysine use but does not replace the original's arginine and ornithine.
