Turn back the clock? While humans live longer than ever, some dog breeds seem to die younger. Young at Heart uses new "life extension" advances with the goal of returning your dog's metabolism to that in its prime.

Young AT Heart Longevity and Anti-Aging Formula

  • Combat muscle loss and support joints- Reverse muscle loss associated with aging(sarcopenia). Reversing muscle loss boots metabolism, strengthens joints and resistance and helps avoid your dog becoming a "shadow of its former self".
  • Restore healthy water balance- Hydrate older canine bodies, optimizing cellular water balance. "Volumizing" cells creates favorable metabolism for optimal health.
  • Support mental function- Phosphytidylserine and other nutrients are sugested to favorably influence age related cognitive decline (A.R.C.D.).
  • Enhance digestion and absorption- Partially predigested calories used in elite medical and sports foods reduce stomach distress in older animals, while boosting uptake.
  • Support eye and healthy heart- Antioxidants litein, zeaxanthin and other related phyto-factors have been demonstrated to support macular (eye) health. Co Q10, ribose and others may assist heart finction in older animals.

The Commitment To a Healthy Planet, Healthy Pets

As never before, consumers seek natural foods for themselves, their pets and to support the health of our planet. They recognize healthy people and pets depend upon a healthy earth. ANIMAL NATURALS is the preeminent pet line using human-grade nutrition with over 20 years success in natural nutrition. We are a “green” company that stresses recycling and conservation. ANIMAL NATURALS gives consumers the best in natural pet care while treating the earth with respect.

  1. Proven Effectiveness :Two decades of unparalleled success in Olympics, pro sports, police dog and other grueling arenas prove our formulas the gold standard to which others are compared. Each strengthens metabolic weak links for a specific stage of life. New natural healing formulas rival prescription drugs.

  2. Natural Ingredients :Beyond natural, beyond organic are “evofoods” that recreate evolutionary diets. In 1981, we originated evofoods and have improved them to a higher degree than anybody. Incredible smell and taste from the finest whole foods and extracts are unrivaled in the industry. No artificial colorings, flavorings or preservatives.

  3. Recyclable :Packaging materials are blends of recycled and/or recyclable, biodegradable materials. Food ingredients are from sustainably grown, renewable stocks. We never knowingly use depleted, high conservation or endangered sources.

  4. State-of-the-Art Science :For 20 years, we’ve created-then improved-the most advanced products in the world. Scientists help scan hundreds of medical journals for new breakthroughs in natural medicine, sports science, etc. to make products evermore powerful and cost effective.

  5. Clean Production :We go the added step to produce under strict GMP standards. We believe you should not feed your pet any ingredient you would not eat yourself, or from a packaging facility you would not eat in.



NATURAL USED TO MEAN LAST PLACE. When I began creating human and canine foods, natural was code for “ineffective”. Natural nutrition just wasn’t effective; natural athletes lost to druggies. Natural bodybuilders looked like scrawny kids next to druggies. In drug tested contests, performance levels fell dramatically.

To insiders, natural was a joke.

22 years later, natural foods I helped develop make today’s human and canine athletes leaner, faster and stronger. Improvements in power, strength and endurance are almost beyond belief. These products allow athletes to train harder, more often. The day to day difference in accelerating recovery and reducing muscle damage exceed even performance drugs. As proof, natural athletes tested for drugs actually beat drugged athletes and shatter old drug records.

Natural is no longer a joke.

Literally millions of athletes have set new levels of personal performance using these breakthroughs.

How did these products grow to eclipse drugs and power virtually every modern athlete? Renowned scientists from local universities Stanford and Berkeley helped. So did pro athletes and dogs to test on. But the real key to ongoing innovation of these natural products was not science, but Nature. Unlocking more hidden genetic potential required a fresh look at the evolutionary design of humans and canines.

By coaxing Nature’s DNA secrets from the human, canine and equine body, my past products have changed the rules for drug-free performance. But my newest products surpass everything that’s gone before, in my opinion. These formulas contain power and safety impossible just a few years ago. Since increased performance is founded on health, overall health is raised.

And my new therapeutics make natural healing a reality. Until now, natural remedies for pets were even more of a joke than nutrition used to be. A nice idea that just did not work.

My new healing formulas rival prescription drugs effectiveness, yet are 100% natural…and cost less!

22 years ago, I transformed natural from a joke into a revolution, changing sports forever. It’s hard to find a serious athlete who has not raised performance and health through the use of these products. Everyday, throughout the world, Professional, Olympic and other athletes use these formulas to compete against—and beat—drugged athletes.
