うつ対策に、期待!

うつに強い精神を作るためにいろいろ調べていたら、トリプトファンがよいということにたどりつき、色々調べた結果こちらの商品にたどり着きました。 効果が出るまでに2~3ヶ月は必要との調べがあったので、しばらくは飲み続けてみたいと思います。期待を込めて☆4つ。
全く効果がありませんでした

パニック障害で心療内科にかかっています。 最近気分の落ち込みが激しく、主治医の先生からダグラス社の5HTPを処方され、すごく効果がありました。 こちらでは5HTPの取り扱いがないようなので、同じセロトニンを作る働きがあるL-トリプトファンを購入してみました。 結果はまったく効果がなく高い買い物となってしまいました。 L-トリプトファン→5HTP→セロトニンと変換されるらしいですが、L-トリプトファンを摂取してもセロトニンへの変換率はかなり低いらしいです。
