Hero Pet Health vs PAW Complete Calm: Which Is Better?
PAW Complete Calm is one of the most well-known Tryptophan chews in Australia. But is a single ingredient enough? We compare it against Hero’s triple-action formula.
The Short Answer
PAW Complete Calm is an excellent choice if you specifically want a high-dose Tryptophan supplement (180mg) for serotonin support.
Hero Calming Chews are the better choice for broader anxiety support. Hero targets 3 pathways simultaneously: Serotonin (Tryptophan), GABA (Magnesium), and Cortisol (Ashwagandha). If your dog hasn't responded to Tryptophan alone, Hero's multi-modal approach often yields better results.

|---|---|---|
| Approach | Triple Pathway Serotonin + GABA + Cortisol | Single Pathway Serotonin only |
| Key Actives | Tryptophan Magnesium Ashwagandha Chamomile | Tryptophan (180mg) B Vitamins |
| Flavour | Beef Liver | Kangaroo |
| Price | $49.95 ($42.46 on sub) | ~$45.00 - $55.00 (varies by retailer) |

Tryptophan vs. Multi-Modal: Which Works?
PAW Complete Calm relies heavily on Tryptophan. Tryptophan is the precursor to Serotonin, the "feel-good" neurotransmitter. For dogs whose anxiety is driven by low serotonin, this can be very effective.
However, anxiety is complex. It often involves the stress hormone Cortisol and the "brake pedal" neurotransmitter GABA.
Hero Pet Health takes a "shotgun" approach rather than a "sniper" approach. By including Magnesium (essential for GABA function) and Ashwagandha (proven to lower cortisol), it targets the dog's nervous system from three angles simultaneously. This is why many owners see results with Hero when simple Tryptophan treats haven't worked.
Try the Triple-Action Approach
If your dog needs more than just Tryptophan, switch to Hero. Vet-reviewed, Australian made, and backed by a lifetime guarantee.

Can I give Hero Calming Chews every day?
Yes. The ingredients in Hero (Magnesium, Ashwagandha, Tryptophan) are safe for long-term daily use. In fact, adaptogens like Ashwagandha work best when built up in the system over time.
Do they make my dog drowsy?
No. Neither Hero nor PAW are sedatives. They work by supporting a balanced nervous system state, not by knocking the dog out. Your dog should remain alert but less reactive to stressors.
