Training Stack - Lemon

The Thorne Training Stack in Lemon is formulated to support your full training window — before and after exercise. Anchored by Beta Alanine-SR, it helps support muscle work capacity, normal muscle acidity levels, and perceived time-to-exhaustion across both anaerobic and aerobic efforts.

Giving as much thought to your nutrition both before and after exercise, as you do to planning and packing your gear, scheduling your training, and recording your results, will make a noticeable difference in your day-to-day activity. Although most athletes tend to focus their attention on their physical exertion during a workout, a majority of the factors to achieve a successful training session occurs before and after the workout.

Beta Alanine-SR is required for the body to make carnosine, which is responsible for buffering the hydrogen ions created during energy production in the muscles.* Carnosine helps maintain normal acidity levels in the muscles, because acidity is a major contributor to muscle fatigue. Supplementing with beta alanine supports muscle health, muscle work capacity, and perceived time-to-exhaustion in both anaerobic exercise that lasts 1-4 minutes and aerobic exercise that lasts longer than four minutes.* Beta alanine has also been shown to benefit athletic performance.* For example, studies have shown improvements in fatigue in cyclists, in 2,000-meter rowing time trials, in strength in college football athletes, and in sprint performance in endurance cyclists.* Two tablets of Thorne’s Beta-Alanine-SR contain 1.6 grams of sustained-release beta-alanine (as CarnoSyn®).

Creatine plays an important role in the production of cellular energy because it helps the body make ATP, the molecule needed by all of the body’s cells and the one that has been shown to support increased work capacity and power output of muscle while also promoting physical endurance and lean body mass gain.* Each serving of Thorne’s Creatine contains 5 grams of creatine monohydrate.

Amino Complex contains a high amount of branched-chain amino acids in a formula that has been validated through numerous clinical trials for promoting lean muscle mass and muscle strength.* The branched-chain amino acids in Amino Complex promote mitochondrial biogenesis, which provides energy to the cells.* Amino acid supplementation has also been shown to decrease fat synthesis and promote energy production.* Thorne’s Amino Complex is available in either lemon or berry flavor and provides 7.6 grams of branched-chain and essential amino acids per serving.

Because an athlete needs to know that his or her nutritional supplements are trustworthy and quality compliant, every batch of an NSF Certified for Sport® product is tested for compliance with the claims on its product label and to ensure the absence of more than 200 substances banned by many major athletic organizations, including stimulants, narcotics, steroids, diuretics, beta-2 agents, and masking agents.

Suggested Use:

Beta Alanine-SR: Take two tablets 1-2 times daily, or as recommended by a health-care or performance professional. Creatine: Mix 1 level scoop with at least 8 ounces of water, juice, or preferred beverage once daily, or as recommended by a health-care or performance professional. Can be used 30-90 minutes before or after exercise. Amino Complex: Mix 1 scoop with at least 8 ounces of water one to two times daily, or as recommended by a health-care or performance professional.

How the Thorne Training Stack Fits Your Training Routine

• Pre-workout preparation: Take it as part of a nutrition routine before training to help support muscle carnosine levels and readiness for sustained effort.
• Endurance and high-intensity sessions: Beta Alanine-SR supports perceived time-to-exhaustion in both short anaerobic bursts (1–4 minutes) and longer aerobic activity.
• Post-workout recovery window: Designed with the full training session in mind, it fits naturally into both pre- and post-exercise nutrition planning.
• Consistent training performance: Studies cited by Thorne show benefits in cyclists, rowers, and football athletes — making it a versatile option across sport types.

Frequently Asked Questions

What does Beta Alanine-SR in the Thorne Training Stack do?

Beta Alanine-SR supports the body's production of carnosine, which helps maintain normal acidity levels in muscles during exercise. This is associated with supporting muscle work capacity and reducing the perception of fatigue.

Is the Thorne Training Stack suitable for both endurance and strength athletes?

Based on Thorne's description, beta alanine has been studied in cyclists, rowers, and college football athletes, suggesting it may fit into routines across multiple training disciplines. Always consult a healthcare professional before starting any supplement.

When should I take the Thorne Training Stack Lemon?

Thorne recommends giving as much attention to nutrition before and after exercise as to the workout itself, positioning this stack as a complement to both your pre- and post-workout nutrition routine. Consult the product label for specific usage guidance.
