It now has a flavoring I can't tolerate. No returns on this item. I'm sure most people will be fine with it. It's frustrating I can't return it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/88952794-klaire-labs-sfi-health-thera-b-essential-vitamin-b-complex](https://www.desertcart.sg/products/88952794-klaire-labs-sfi-health-thera-b-essential-vitamin-b-complex) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-09*
