B- Goal FitC- Strength of SupportD+ CoverageA- Formula Quality

Metabolic and neurological health are supported by 300mg of n-acetyl l-tyrosine and foundational B-vitamins. Folic acid and Vitamin B6 contribute to the synthesis of essential neurotransmitters and support fundamental methylation processes for long-term wellness.

The use of synthetic folic acid and the absence of Vitamin B12 may limit the effectiveness of the methylation support compared to more comprehensive complexes. This formulation targets a narrow set of pathways, providing depth for specific amino acid requirements while omitting broader daily nutritional coverage.

Lower effect
F Goal FitD Strength of SupportF CoverageF Formula Quality

This targeted amino acid supplement provides folate and vitamin B6, which are supportive of cellular division in the hair bulb. However, it lacks all foundational hair nutrients and structural building blocks.

The inclusion of N-Acetyl L-Tyrosine has minimal direct evidence for improving hair thickness or growth. It appears poorly suited for achieving significant improvements in hair health.
