Why Choose Sighed Effects Tools
We built these tools differently—prioritizing research integrity over monetization.
No Affiliate Links or Brand Recommendations
We don't recommend specific brands or products. Smart Stack focuses on ingredients and timing—you choose which brands to buy based on your budget and quality preferences. No commission-driven recommendations.
Research-Based Algorithms, Not AI Generation
Our tools use deterministic algorithms built from peer-reviewed research on bioavailability, interactions, and timing. Every recommendation follows established clinical data—not language model predictions. Consistent, reproducible results based on science. No hallucination concerns.
Transparent Methodology
Our recommendations include explanations and citations. We prioritize supplements with strong evidence from systematic reviews and meta-analyses, not theoretical benefits or industry marketing claims.
