Review: Works as described. - This product really boosts my mood and makes me feel calm. The combo is incredible for me. The label has a caution against taking this with other prescription medication, so check with your doctor. Preferably a functional medicine doctor. Research each ingredient separately, and as a combo. Consider trying this company's saffron only product by itself first, for example.

Review: Ideal si tienes bajos dopamina, serotonina, aceitilcolina y gaba - Lo recomiendo a mis pacientes después de realizar test de neurotransmisores. Este producto ayuda a que los produzcas de nuevo de forma natural. Tres meses es lo ideal para que se regulen los que producimos de forma natural. Si tomas antidepresivos no los tomes juntos. El antidepresivo ayuda pero cuando lo quitas no te ayudo a producir neurotransmisores de forma natural. En cambio estos ingredientes ayudan a que produzca tu propio cuerpo los neurotransmisores. Lo recomiendo muchísimo.

### ⭐⭐⭐⭐⭐ Works for me.
*by T***. on 5 April 2022*

I take one pill in the morning w/a additional natural source 200 mg l-theanine pill and a probiotic (different brand) and I'm good to go for the day. I'm definitely not a morning person, and notice my mood is more positive for the day. I recently ran out and noticed my bitter mood returning, tried to order more but they weren't in stock. Hopefully that stay in stock, will purchase again.
