Muso From Japan Organic Ponzu, 8.5 Fl Oz
This USDA-certified organic ponzu delivers only about 1g net carb per tablespoon (versus roughly 2g for mainstream Kikkoman) and skips the sugar-heavy fillers and sodium benzoate preservative found in typical bottled ponzu, making it the cleaner low-carb pick that Cast Iron Keto specifically calls out as "an excellent keto friendly alternative."
Wan Ja Shan Organic Ponzu, Citrus Seasoned Soy Sauce & Dressing
Handcrafted and brewed in New York with over 70 years of tradition, this USDA-certified organic, gluten-free ponzu swaps imported sourcing for a domestic supply chain while keeping the same tangy citrus-soy profile keto shoppers want in a ponzu — a solid pick for anyone prioritizing USA-made, wheat-free condiments over imported Japanese brands.
San-J Citrus Tamari Splash (Gluten-Free Ponzu)
Built on San-J's reduced-sodium tamari instead of standard wheat-containing shoyu, this ponzu-style splash blends yuzu, lemon and mandarin for a brighter citrus punch and is certified gluten-free, kosher and Non-GMO — the go-to choice for keto dieters who also need to avoid wheat/gluten, at about 2g carbs per tablespoon.
