How this protocol works
In plain language
Reactive hypoglycemia (postprandial hypoglycemia) is low blood sugar that occurs 2-4 hours after eating, typically after a high-carbohydrate meal. The body overreacts to rising blood sugar by releasing too much insulin, causing blood sugar to drop too low. Symptoms include shakiness, sweating, rapid heartbeat, anxiety, irritability, hunger, dizziness, and difficulty concentrating. Symptoms resolve quickly after eating, which is diagnostic.
IMPORTANT: Reactive hypoglycemia is primarily managed through dietary changes, not supplements. The key strategies are: 1) Eat smaller, more frequent meals; 2) Limit refined carbohydrates and sugars; 3) Include protein, healthy fat, and fiber with every meal; 4) Avoid sugary drinks and alcohol on an empty stomach; 5) Choose low-glycemic index foods. If symptoms are severe or don't respond to dietary changes, medical evaluation is needed to rule out underlying causes (dumping syndrome after gastric surgery, rare insulin-producing tumors). These supplements may help support blood sugar stability but work best alongside dietary changes.
Not listed here: supplements sold to lower blood sugar, such as berberine, chromium, alpha-lipoic acid and cinnamon. They are studied for high blood sugar. For someone whose blood sugar already drops too low after meals, they could make the lows worse.
Fiber supplements* (like psyllium or glucomannan) taken before meals slow carbohydrate absorption, preventing rapid spikes and subsequent crashes.
Magnesium* is involved in glucose metabolism, and deficiency impairs insulin function.
Protein* added to meals helps moderate the blood sugar response to carbohydrates.
Vitamin D* supports insulin function, and deficiency is associated with glucose intolerance.
Expected timeline: Dietary changes provide the fastest relief, often within days. Supplements like fiber work acutely when taken before meals.
