The Hidden Malabsorption Crisis
Celiac disease attacks the microvilli in your small intestine. These tiny, finger-like projections are solely responsible for absorbing nutrients from your food into your bloodstream.
When they are flattened by celiac disease, you can eat the healthiest, most organic diet in the world, and your body will simply pass the nutrients right through you. You are literally starving on a full stomach.
If you have celiac, you are almost certainly deficient in these three nutrients, and you need high-quality, gluten-free supplements immediately.

Nutrient 1: Iron (Ferritin)
Iron is absorbed in the duodenum—the exact part of the intestine that celiac damages first. Severe anemia, bone-crushing fatigue, and dizziness are the primary symptoms.
Most cheap iron pills will destroy your stomach and cause severe constipation. You need a bioavailable, blood-building formula.
Our Recommendation:
MegaFood Blood Builder Iron Supplement — Made from real food, clinically proven to increase iron without stomach upset, and Certified Gluten-Free.
Nutrient 2: Vitamin D3 & K2
Because celiacs uniquely struggle to absorb dietary fats, they invariably become deficient in fat-soluble vitamins like Vitamin D. This leads to early-onset osteoporosis, depression, and a shattered immune system. To absorb D3 properly, it MUST be paired with Vitamin K2.
Our Recommendation:
Sports Research Vitamin D3 + K2 — A highly potent, coconut-oil based softgel that ensures maximum absorption even in damaged guts.
Nutrient 3: Vitamin B12
B12 is absorbed at the very end of the small intestine. Deficiency causes terrible brain fog, numbness in the hands and feet, and chronic exhaustion. Celiacs need a sublingual (under the tongue) form so it bypasses the damaged stomach entirely.
Our Recommendation:
Pure Encapsulations B12 Liquid — Designed specifically for sensitive immune systems, totally free of wheat, gluten, egg, and peanuts.

Scan Everything in the Pharmacy
Unfortunately, cheap generic vitamins often use wheat starch as a binder to hold the tablet together. Never buy a pharmacy-brand vitamin without checking. Use the Check Gluten scanner to ensure your medicine isn't secretly poisoning you.
