Frequently Asked Questions

Most electrolyte brands pack their products with maltodextrin, artificial dyes, and cheap sweeteners. We don't. Cast Iron Nutrition was built on the conviction that your body is a temple — so every ingredient we use is intentional, clean, and functional. 1,000mg sodium, 200mg potassium, 60mg magnesium glycinate, and monk fruit. That's it.
Absolutely not. We ban Red 40, Blue 2, Yellow 5, Yellow 6, sucralose, aspartame, stevia, dextrose, and maltodextrin from every product we make. Artificial dyes have been linked to hyperactivity and long-term health risks — we said no before it was even a conversation.
Each serving contains 1,000mg of sodium — significantly more than most competitors. That's intentional. During intense training your body loses 500–2,000mg of sodium per hour through sweat. Low-dose products simply don't replace what you lose. We built Cast Iron to actually perform, not just look good on a label.
Yes. Because every ingredient is clean and purposeful, Cast Iron is designed for daily use. Whether you're training hard, recovering, or just staying hydrated through your day — our formula supports consistent electrolyte balance without the junk that accumulates with repeated consumption of artificial additives.
Every batch of Cast Iron Nutrition is proudly manufactured in the United States. We believe in American-made quality and the accountability that comes with domestic production. You know exactly where your product comes from — and so do we.
