The Animal series of supplements is the elite performance line from Universal Nutrition, built for serious athletes who demand more than just the basics. Since their debut in the early 1980s, Animal products have been engineered with potent, precisely dosed formulas designed to fuel intense training, accelerate recovery, and support peak performance year-round.

Universal Nutrition

Founded in 1977 at the height of the golden era of bodybuilding, Universal Nutrition started as a small, family-run manufacturing operation in Linden, New Jersey, with a mission to provide athletes with the highest-quality sports nutrition possible. Today, the company remains privately owned and family-operated, now headquartered in New Brunswick, NJ, and is recognized worldwide as one of the most respected names in the industry.

Over the decades, Universal Nutrition has evolved from a modest operation into an industry pioneer, operating state-of-the-art, GMP-certified manufacturing facilities that ensure every product meets the strictest standards for purity, potency, and consistency. With more than four decades of experience, Universal Nutrition continues to uphold its original commitment — producing supplements that work as hard as the athletes who use them.

Creation of the Animal Line

In 1983, Universal Nutrition introduced something groundbreaking: the “pack” system, now best known as Animal Pak, their flagship product. This innovation offered a daily packet loaded with essential nutrients tailored to support heavy training—a format that remains influential today. The Animal brand has since evolved into a broad line of intensely formulated supplements designed specifically for serious training needs.

Customer Reviews: Animal Pak Powder

Best powder form Multivitamin / BCAA I've used in a long time

“I used to religiously use Animal Pak tablets but the biggest downside of it was having to swallow those gigantic pills. Though this is not quite as convenient as the little packs that the pills come in, I find it a lot easier to use. Its become a regular part of my supplement routine and I've noticed a big difference in my mood, energy, and strength since I've started taking them. Definitely worth a try if you're looking for a good multivitamin/bcaa.”

How to Choose the Best Universal Nutrition Animal Supplements

Choosing the right Animal supplement depends on your fitness goals and nutritional needs. Here are some easy tips to help you decide:

Identify Your Goal: Animal supplements serve different purposes, like boosting muscle growth, increasing strength, enhancing recovery, or supporting hormone balance. Know whether you want muscle building (like Animal Stak or M-Stak), overall nutrition (Animal Pak), or strength and performance (Creatine products).

Check the Formula: Look at the key ingredients in each Animal supplement. For example, Animal Stak focuses on testosterone support with herbal extracts, while Animal Pak offers a complete vitamin/mineral blend. Choose a formula that matches your body’s needs.

Consider Your Training Level: If you train very hard or are a serious athlete, comprehensive packs like Animal Pak or Animal Stak can be more effective. For more targeted support, supplements like Creatine HMB+ or Creatine Chews are ideal for boosting power and endurance.

Think About Convenience: Animal supplements come in pills, powders, or chews. Pick the form that fits your lifestyle and makes it easy to stay consistent.

Listen to Your Body: Start with the suggested doses and observe how your body responds from a safety perspective. Adjust dosing as needed based on results and how you feel.

Consult Experts: Talk to someone who has knowledge in health & fitness supplementation such as a fitness coach, nutritionist, or healthcare professional before starting new supplements, especially if you have health conditions or take medications.

How to Use Animal Supplements

• Read the label: Follow the recommended dosage and directions on the product package carefully.
• Take with meals: Most Animal supplements work best when taken with food for better absorption.
• Daily use: For foundational packs like Animal Pak and Animal Pak Powder, take one serving daily to maintain nutrient levels.
