SPORT Maintain is an ultramodern rest day reloader + recharger that restores depleted muscle better than anything ever developed.
Take SPORT Maintain to stimulate and nourish anabolic activity for up to 12 hours on rest day. Return to your game bigger, faster and stronger.
Designed for Performance
Healthy for Daily Use
Build Stronger Muscles Faster on Rest Day
Creatine and beta-alanine are top ergogenics that produce the greatest athletic performance enhancements when taken every day, including rest day. This regimen presents challenges:
- Intense training depletes beta alanine and creatine from muscle tissues
- Higher daily dosing may be linked to uncomfortable tingling and bloating
- Stacking, dosing and timing of several supplements is inconvenient
Performance Lab® SPORT Maintain solves these muscle loading challenges on rest day with creatine and beta-alanine innovations – easy to take and stacked to perform.
Creapure® pH10 Creatine, 3000 mg
SPORT Maintain Creapure® pH10 replenishes creatine muscle stores on rest days. Consistent daily supplementation is the best way to unlock creatine’s full ergogenic benefits, including:
SPORT Maintain maximizes all of these creatine benefits by keeping levels elevated in muscle tissues, supporting growth and repair while charging you up for your next high intensity session.
SPORT Maintain Creapure® pH10 is a quality 99.5% pure form of pH-balanced creatine monohydrate that enhances bioavailability while reducing creatine bloating and gastric distress.
SR CarnoSyn® Beta-Alanine, 1600 mg
SR CarnoSyn® is advanced Beta-Alanine: An overall pre- and post-workout muscle booster that works by raising muscle carnosine.
Consistent muscle carnosine loading is one of the most important sports nutrition practices because it supports both muscle recovery and subsequent muscle performance:
SR CarnoSyn® muscle recovery support
- Antioxidant activity to neutralize exercise-induced, muscle-damaging free radicals;
- Inhibits protein-damaging advanced glycation end-products (AGEs);
- Acts as a muscle-alkalizing pH regulator, buffering impact of muscle-damaging acids
SR CarnoSyn® muscle performance support
- Increases the working capacity of muscle across all strength and endurance activities;
- Delays muscle failure by reducing acidosis and boosting muscle buffering capacity;
- Boosts overall muscle strength and endurance
SPORT Maintain SR CarnoSyn® is innovative sustained-release (SR) Beta-Alanine that gradually raises and maintains muscle carnosine for 12 hours of steady anabolic nourishment on rest day. SR CarnoSyn® remains in the body longer for peak loading and higher dosing without Beta-Alanine tingling discomfort.
SPORT Maintain + SPORT Pre + SPORT Post is your convenient solution for getting the consistent daily beta alanine and creatine intake shown to produce the best muscle benefits in human research.
NutriGenesis® Iron, 2.5 mg
The harder you train, the more you need iron: Exercise reduces iron absorption while accelerating iron loss through sweat.
Low iron limits red blood cells’ oxygen transport ability – potentially leading to reduced exercise capacity, fatigue and sub-par overall physical performance.
SPORT Maintain NutriGenesis® iron is complexed with a matrix of absorption-enhancing cofactors – making it easy for athletes to restore and sustain ideal iron levels required for peak performance.
SPORT Maintain is an ideal rest day supplement for anyone seeking the greatest gains from their strength training program.
On rest days, take 3 capsules in the morning and 3 capsules in the afternoon on an empty stomach. Take SPORT Maintain consistently.
For best results, take SPORT Maintain with SPORT Pre and SPORT Post. Designed to stack together, SPORT Maintain + SPORT Pre + SPORT Post is the world’s most convenient solution for getting the consistent daily beta alanine + creatine intake shown to produce the best muscle benefits in human clinical research.
Like other Performance Lab® supplements, SPORT Maintain is designed to be safe for long-term daily use, without the need for cycling. SPORT Maintain achieves this by using pure, potent ingredients that are dosed appropriately and in line with clinical research. SPORT Maintain’s clean formula design – free of GMOs, gluten, soy, colorants, preservatives and other additives – is also well-tolerated by the body, and safe for long-term use. SPORT Maintain avoids the use of caffeine and stimulants, further strengthening its safety and tolerability profile.
NutriGenesis® is a Performance Lab® nutrition technology innovation: Vitamins, minerals and amino acids grown in live cultures at our state-of-the-art lab.
A true biological nutrient form, NutriGenesis® closely mirrors the molecular structure of food nutrients. NutriGenesis® nutrients offer significant advantages over standard nutrient forms.
Featured in several Performance Lab® formulas, NutriGenesis® vitamins, minerals and amino acids are bioengineered to be safe, active and highly effective for overall health and performance.
Vitamins, minerals and amino acids are the most important nutrients you need to build a strong foundation for health and performance.
Performance Lab® developed NutriGenesis® to have our own in-house vitamins, minerals and amino acids to use in our own nutritional supplements.
In producing NutriGenesis®, Performance Lab® can best maintain our industry-leading quality standards for cleanliness, purity, effectiveness and eco-friendliness, across all our ultramodern formulas.
Not all vitamins, minerals and amino acids are the same. There are many nutrient forms, produced with a variety of processes. Some of the most popular nutrient forms available in supplements today include:
Whole Food Concentrates
Whole food vitamin and mineral supplements are sourced from fruits, vegetables, herbs and mushrooms. They include natural cofactors that make food nutrients so easy for the body to absorb and utilize. However, they do require extensive processing and may be made with GMOs, mass agriculture and dirty eco-destructive practices.
Isolated Chemical (USP) Nutrients
Isolated Chemical (USP) is the cheapest vitamin and mineral form found in the most basic multivitamin supplements. This synthetic form chemically alters vitamins and minerals, isolating them from their whole-food cofactors. As a result, Isolated Chemical (USP) nutrients are typically harder to absorb and less effective than whole food nutrients.
In this process, a mineral nutrient (such as iron, calcium, zinc) is bound with a chelator: An organic molecule (often an amino acid) that is large enough to enrobe the mineral. By surrounding the mineral, the chelator protects it against degradation. Chelated nutrients are highly stable and may improve nutrient uptake and utilization.
NutriGenesis® is different from traditional nutrient forms: Bioengineered to be better.
NutriGenesis® are cultured nutrients that replicate the creation of vitamins, minerals and aminos in nature.
NutriGenesis® is based on the work of Nobel Prize-winning physiologist Albert Szent Gyorgy, who theorized that nutrients presented in their naturally grown forms supply cofactors that make them more bioavailable, biologically active and effective than nutrients that are isolated.
In the NutriGenesis® process, single-cell organisms (Lactobacillus probiotics and brewer’s yeast) are seeded with micronutrients in a hydroponic growth medium.
The live single-cell organisms “eat” the micronutrients, divide and thrive. As the cultures grow, they produce fresh new NutriGenesis® vitamins, minerals and aminos within a matrix of natural cofactors. This familiar structure is more easily absorbed and utilized by the body.More on the NutriGenesis® Process
NutriGenesis® advantages over other forms:
NutriGenesis® is essentially food nutrition. Mirroring food nutrients molecule-by-molecule, our vitamins, minerals and aminos are presented in pure elemental form. Maximum nutrition: Nothing more, nothing less.
Enhanced effectiveness. Because NutriGenesis® nutrients are in food-matrix form, they are recognized by the body as nature-identical -- maximizing nutrient uptake, bioavailability and beneficial activity.
Patented and researched. The patented process behind NutriGenesis® has been shown in research to enhance nutrient absorption and retention (when compared to chemical isolates).
Cleaner and safer. NutriGenesis® is produced in a sterile, tightly controlled lab setting. NutriGenesis® is minimally processed, requiring no pesticides, herbicides or other synthetics associated with some other whole-food nutrients.
Better for the planet: The NutriGenesis® process is clean and efficient, with little carbon footprint or environmental impact – especially when compared to factory farming for phytonutrients and strip mining for minerals.
It all begins with NutriGenesis® Multi for Men and Multi for Women: Performance Lab®’s multivitamin starting point for human performance optimization.
NutriGenesis® vitamins, minerals and amino acids are also found in Performance Lab® formulas Stim, Flex, BCAA, Pre, Post and Maintain.
Beyond Performance Lab®, NutriGenesis® B-Vitamins are found in Mind Lab Pro®: the Universal Nootropic™.
