About this product

A useful 800 mg tyrosine amount is paired with B vitamins that support neurotransmitter and energy metabolism. Active folate and methylcobalamin improve the quality of the cofactor blend.

The label says generic tyrosine rather than confirming the preferred L-isomer. Several B vitamins add breadth but also raise the cost without creating direct memory support.

It fits adults seeking tyrosine plus metabolic cofactors for demanding periods. A plain L-tyrosine product is more economical when the B-vitamin blend is unnecessary.

Who is it for
  • adults seeking tyrosine plus metabolic cofactors for demanding periods
  • Adults who understand the formula’s focused role
  • Users comfortable with the stated limitations
Best for
  • Tyrosine with B-vitamin cofactors
  • Demanding mental periods
  • Users wanting active folate and B12

Pros

  • Useful 800 mg tyrosine amount
  • Includes active folate and methylcobalamin
  • Broad B-vitamin support

Cons

  • L-isomer is not confirmed
  • Higher cost than plain tyrosine
  • No direct memory or neuroprotection ingredients

Warnings

  • L-tyrosine may conflict with levodopa, MAO inhibitors, or thyroid-hormone treatment
  • People with hyperthyroidism should avoid unsupervised tyrosine use
  • Tyrosine can feel stimulating or cause digestive upset in sensitive users

Product analysis

74 out of 100
The core formula provides a clearly defined role with practical strengths. The label says generic tyrosine rather than confirming the preferred L-isomer.

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

Nutrient quality82

Tyrosine and several well-regarded B-vitamin forms create a coherent metabolic formula. Generic tyrosine naming and relatively high amounts of some B vitamins temper the formulation quality.

Ingredient transparency83

Every active ingredient has a specific amount, and no proprietary blend hides the formula. Tyrosine is not identified as the preferred L-form, and full non-active details are absent.

Customer satisfaction55

The aggregate rating is positive, but the very small review base makes it uncertain. No detailed feedback is supplied to assess recurring complaints or purpose-specific experiences.

Value for money69

Relevant B vitamins add breadth around a substantial tyrosine amount. The more complex formula provides only moderate category value for focused tyrosine use.

Tyrosine may help with mental performance during acute stress or sleep loss, but whether it helps when you're rested is unclear. The B vitamins also matter for normal brain function, particularly when intake is low. That nutritional role doesn't mean extra amounts improve thinking when you already get enough, and the niacin amount is unknown here.

How this product is rated for Brain Health

Ingredient fit72

B vitamins are relevant to normal brain function; additional cognitive benefit depends on the ingredient and your nutritional needs.
Goal fit
