Training Stack - Berry

The Thorne Training Stack in Berry is formulated to support both pre- and post-workout nutrition, addressing what happens before and after physical exertion—not just during it. With Beta Alanine-SR at its core, it supports muscle work capacity, normal muscle acidity levels, and perceived time-to-exhaustion across 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 6 ounces of water one to two times daily, or as recommended by a health-care or performance professional.

Warnings:

How the Thorne Training Stack Fits Your Training Routine

• Pre-workout preparation: Use it as part of a structured nutrition approach before training sessions to support muscle readiness and help buffer hydrogen ions produced during energy output.
• Sustained aerobic efforts: Supports perceived time-to-exhaustion during aerobic exercise lasting longer than four minutes, making it relevant for endurance athletes such as cyclists and rowers.
• Short-burst anaerobic work: Formulated to support muscle work capacity during high-intensity efforts in the one-to-four minute range, applicable to sprint and strength-focused training.
• Recovery window nutrition: Integrates into post-workout routines to support the muscle health factors that are just as critical as the workout itself.

Frequently Asked Questions

What is Beta Alanine-SR and why is it in the Thorne Training Stack?

Beta Alanine-SR is a sustained-release form of beta alanine, an amino acid the body uses to produce carnosine, which helps maintain normal acidity levels in muscles during exercise. It supports muscle work capacity and perceived time-to-exhaustion in both aerobic and anaerobic activity.

When should I take the Thorne Training Stack Berry?

The stack is designed to support nutrition both before and after exercise, recognizing that much of what contributes to a successful training session occurs outside the workout itself. For specific timing guidance, consult the product label or a qualified health professional.

Is the Thorne Training Stack Berry suitable for endurance athletes?

It is formulated to support athletic performance across both endurance and strength-based disciplines, with research referenced for cyclists, rowers, and sprint athletes. As with any supplement, individual needs vary.
