PetAg Dyne Endurance & Vitality Supplements for Dogs (60 Soft Chews)

Vet-Formulated L-Carnitine and Astaxanthin Supplement for Active and Aging Dogs 

Product Description

Dyne Endurance and Vitality Soft Chews are vet-formulated, cold-pressed supplements for active and aging dogs, delivering five clinically studied active ingredients to support stamina, muscle function, recovery, and reduced oxidative stress. Carniking® L-Carnitine converts fat into usable fuel and supports lean muscle mass. AstaReal® Astaxanthin reduces the impact of oxidative stress from activity or aging. Omega-3 fatty acids, folic acid, and choline complete the formula.

Benefits

• Carniking® L-Carnitine for Energy and Recovery: L-Carnitine from Carniking® converts fat into cellular energy, fuels active dogs during performance, and supports lean muscle mass and recovery in aging or underweight dogs.
• AstaReal® Astaxanthin as Antioxidant: Astaxanthin from AstaReal® Biomass Flakes is a powerful natural antioxidant that helps reduce the oxidative stress caused by physical activity and normal aging processes in dogs.
• Omega-3 Fatty Acids for Inflammation and Brain Health: Omega-3 fatty acids from fish oil reduce exercise-induced inflammation and support heart and brain health, which is important for dogs with consistently high energy output.
• Folic Acid for Cellular Metabolism: Folic acid supports cellular regeneration and metabolism, contributing to sustained vitality and energy production at the cellular level alongside the L-Carnitine in this formula.
• Cold-Pressed to Protect Active Ingredients: These chews are cold-pressed rather than baked, meaning no high heat is used during manufacturing, a process that can break down sensitive nutrients before the dog ever consumes them.

• Give directly as a treat: The chicken liver flavor allows these to be given directly to your dog as a treat.
• Mix with food if needed: If your dog is selective, break the chew into smaller pieces and mix with a small amount of wet food or their regular meal.
• Give consistently for best results: Daily use allows active ingredients like L-Carnitine and Astaxanthin to build up over time.

Frequently Asked Questions

Q1: What does L-Carnitine actually do for a dog?

Ans: L-Carnitine is what moves fatty acids into the mitochondria, where the cell converts fat into energy. For active dogs, that means the body burns fuel more efficiently during exercise. For older dogs, it helps maintain muscle mass and shortens how long it takes to recover after a hard day.

Q2: What is astaxanthin and why is it in this formula?

Ans: Astaxanthin is a carotenoid antioxidant found naturally in marine algae. It helps reduce the oxidative stress that builds up in cells during exercise and from the normal aging process. Oxidative stress left unchecked can affect muscle recovery, energy levels, and cellular health.

Q3: What does cold-pressing mean for this supplement?

Ans: Cold-pressing means the chews are formed under pressure rather than baked at high heat. Heat breaks down sensitive nutrients, particularly antioxidants and amino acids, before they reach your dog.

Q4: Will this supplement make my dog hyper or overactive?

Ans: No. This formula supports balanced, sustained energy through metabolic pathways, not stimulation. L-Carnitine works by improving how efficiently cells convert fat into fuel, which supports stamina.

Q5: How is the daily dose calculated for a dog that doesn't land on an exact weight bracket?

Ans: The rule is one chew per 25 lbs daily. For a dog that doesn't land exactly on 25, 50, or 75 lbs, start at the lower end, a 40 lb dog would start at one chew and move to two if needed. Your vet can help confirm the right daily amount for your specific dog's weight and condition.

Q6: How long does one jar last?

Ans: A 25 lb dog gets one chew per day, so the 60-count jar lasts 60 days. A 50 lb dog gets two chews daily, lasting 30 days. A 100 lb dog gets four chews daily, lasting 15 days. The supply duration scales directly with your dog's weight, so larger dogs go through the jar considerably faster than smaller dogs.

Q7: Is this supplement suitable for senior dogs?

Ans: Yes. Senior dogs are one of the two primary audiences this formula was developed for. As dogs age, they produce less L-Carnitine naturally, recover more slowly from activity, and experience more oxidative stress at the cellular level.
