NutriStack
Beta-Alanine and Taurine, timing-sensitive.
Beta-alanine and taurine compete for the same transporter, so chronic high-dose beta-alanine can lower tissue taurine levels and vice versa.
One pair, every claim cited. The two substances, the type, the mechanism, the recommendation, and the primary literature.
Same shape as the other 1,729 pairs in the public database.

Timing Sensitive
What is happening. Beta-alanine and taurine compete for the same transporter, so chronic high-dose beta-alanine can lower tissue taurine levels and vice versa.
Mechanism. Both beta-alanine and taurine are substrates for the TauT (SLC6A6) beta-amino acid transporter, so they competitively inhibit each other's cellular uptake when present together.
Recommendation. Separate beta-alanine and taurine doses by at least 2 hours and avoid taking them in the same serving to limit transporter competition.
Minimum separation. 2 hours

Stack Score
How this pair moves the number.
Effect on the composite score
If both Beta-Alanine and Taurine are in the same stack, this pair applies −5 to your Stack Score (per scored timing-sensitive row).
The full algorithm, the clamping rules, and four worked stacks are documented at /methodology/stack-score.
