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

Nutrient Quality20

The histidine form is not clearly disclosed. That limits a confident comparison of its quality with other histidine products.

Ingredient Transparency63

The histidine amount is disclosed. Its form remains unspecified, leaving an important detail unresolved for comparison.

Value For Money100

The histidine amount looks favorable for the serving cost. That supports value for someone specifically seeking histidine.

Customer Satisfaction75

Buyer ratings are positive across a moderate number of reviews. That supports a positive picture of satisfaction, while reviews do not establish health benefits.

Product Focus40

The single-ingredient formula has a narrow purpose. There is not enough goal-specific information to judge which benefits to expect confidently.

77 Performance

Amino Complex Berry Flavored

Thorne

A clearly disclosed essential-amino-acid profile provides useful structural nutrition, though several secondary amino acids are lightly dosed. Compared with the original single-ingredient histidine capsule, the broader active profile adds complementary support, although it is less useful for precise histidine dosing.

70 Performance

Aller-Max

Country Life

Buffered vitamin C, zinc monomethionine, quercetin, N-acetyl cysteine, and histidine form a credible seasonal-support core. Compared with the original single-ingredient histidine capsule, the broader active profile adds complementary support, although it is less useful for precise histidine dosing.

58 Performance

Steel-Libido For Women

Irwin Naturals

The formula combines several relevant actives, but many doses are modest and key fish-oil details are missing. Compared with the original single-ingredient histidine capsule, the broader active profile adds complementary support, although it is less useful for precise histidine dosing.

60 Budget

Daily Amino Acid

21st Century

Several L-amino acids use clear forms, but DL-methionine includes an avoidable non-L isomer. Its lower serving cost improves affordability compared with the original, although broader blends may provide less of the target amino acid.

88 Budget

Pharmaceutical Grade AjiPure L-Histidine 500 mg

Swanson Ultra

A traceable L-histidine source and meaningful amount make this a focused amino-acid option. Its lower serving cost improves affordability compared with the original, although broader blends may provide less of the target amino acid.

85 Budget

Iron Complex

Advanced Nutrition by Zahler

Ferrochel iron, vitamin C, methylcobalamin, folate, and histidine form a focused formula for confirmed iron need. Its lower serving cost improves affordability compared with the original, although broader blends may provide less of the target amino acid.

66 Value

Essential Aminos

Pure Encapsulations

The essential amino acids are clearly identified as L-isomers or stable hydrochloride forms. The broader formula adds complementary ingredients, but the higher serving cost means it is not a clear value upgrade over the original.

65 Value

EAA Pure Blue Raspberry

NutraBio

A broad amino-acid base and useful taurine amount suit exercise recovery and protein support. Serving cost cannot be confirmed from the supplied data, so its value advantage over the original remains uncertain.

72 Value

Aller-Max

Country Life

Buffered vitamin C, zinc monomethionine, quercetin, N-acetyl cysteine, and histidine form a credible seasonal-support core. The broader formula adds complementary ingredients, but the higher serving cost means it is not a clear value upgrade over the original.
