If you're looking for help winding down, only one ingredient here reaches a clinical dose. **GABA** at 200mg per capsule sits within the 100–300mg studied range, which is the primary active doing the work here. At three capsules daily, you'd also reach 600mg of **Glycine** and 600mg of **Taurine** — but both still fall well short of their studied doses (3,000mg and 1,000mg minimum, respectively).

The supporting cast won't do much for you at these doses. **Inositol** at 100mg is about 5% of the dose used in mood research. **Valerian** at 25mg is under 10% of the 300–600mg range studied for sleep. **Magnesium** at 6.5mg is negligible regardless of its premium bisglycinate form.

If your goal is mild relaxation support, the GABA dose may offer some benefit. But for meaningful sleep or stress relief, most of these ingredients are dosed too low to deliver what the research shows they can.
