Spring Energy Fiber + Lactoferrin

Your gut is the engine behind everything you eat in training or out on the course. More than 60% of endurance athletes deal with GI problems during training and racing. Nearly half say it has directly hurt their race performance. The variable most athletes never train is the one that keeps costing them.

Spring Energy Fiber + Lactoferrin is a daily gut optimization formula built specifically for endurance athletes — designed to make your gut more capable of handling the fuel load you're already putting into it.

Lactoferrin: The Gut Lining Protector – Lactoferrin is a bioactive protein found naturally in colostrum — the same compound your body uses to support the immune layer along your intestinal wall. During sustained exercise, blood flow shifts away from your gut, leaving the lining vulnerable. Lactoferrin supports mucosal immune function, helps regulate the gut's inflammatory response under that physiological stress, and has been studied for its role in reducing intestinal permeability after hard efforts. Your gut recovers faster. It handles more.

A Prebiotic Fiber Matrix Built for Athletes – Four soluble fiber sources — oat beta-glucan, green banana powder, acacia, and psyllium husk — work together to feed the beneficial bacteria that produce short-chain fatty acids. Those fatty acids are what maintain your gut barrier and keep it functional during heavy carbohydrate loading. Acacia ferments slowly, so you get the microbiome benefit without the bloating that faster-fermenting fibers cause. Green banana powder delivers resistant starch, a prebiotic that selectively feeds the bacteria you want more of.

Better Carb Absorption When It Counts – A healthy gut absorbs glucose more efficiently than a compromised one. By supporting microbial diversity and maintaining barrier integrity, this formula improves how effectively carbohydrates cross into circulation during long efforts. This is a big way to improve your fueling capacity.

How to Use Spring Energy Fiber + Lactoferrin

Mix: Add one teaspoon (one scoop, 11g) to 12–16 oz of the beverage of your choice.

Timing: Take once daily, 1–2 hours after dinner. Your gut does its most significant repair work overnight — mucosal regeneration, intestinal cell turnover, and microbial fermentation of prebiotic fiber all increase during rest. Evening dosing gives your microbiome the substrates it needs during that repair window.

Pro tip: If you're new to fiber supplements, start with half a scoop for the first 5–7 days. Some adjustment in week one is normal and resolves with consistency. Start 4–6 weeks before your target race — the gut on race day reflects the work you put in before it.

Triathletes, ultra runners, and long-course cyclists who've made this a daily habit report quieter guts during long efforts, better fuel tolerance, and less mid-race urgency. Results build through consistent daily use, with most athletes noticing a meaningful shift in GI comfort within two to four weeks.
