What our customers say

Verified review
"My bloating eased so quickly, and I noticed my skin looking calmer at the same time. My digestion feels more stable and my complexion shows it. Nothing else has worked this well for my gut and skin issues."

Verified review
"I feel noticeably stronger day to day! I have fewer dips in energy and no constant run-down feeling. Vital Tonic has kept my immunity steady and my energy more consistent."
Isobel, 30

Built from years of gut, skin and hormonal imbalance.

I created Loustra because I needed a solution that worked at the foundation, not a surface-level fix. Vital Tonic is the product I couldn’t find — potent, clean and designed for real results.
