Why is it that so few diet products are backed by science? We took a look at Animal Pak to see if it was one of the good ones. We dug into the ingredients, side effects, customer service and clinical research. Then, we read through hundreds of reviews to see what users think. Finally, we condensed it all to give you the bottom line.

Animal Pak Readers: Click here to find out why we're giving away samples of our product, Pronabolin.

What is Animal Pak?

To start, Animal Pak is a multivitamin system designed for athletes. Most of the ingredients are similar to other products in the same category, but there is an amino acid complex, performance complex, antioxidant complex and digestive enzyme complex. You take two packets daily and it looks like a single box of 15 lasts a little more than a week.

Universal Nutrition is the business behind Animal Pak. The company started in the 1970s, so that’s more than four decades in the supplement market. You can purchase online through the official website and outside retailers. We like the addition of the amino and digestive enzyme complexes (among others), but read on…

Pill Problems – “Too Large/Too Many?”

The first thing we noticed with Animal Pak ingredients is that it takes a lot of large pills to deliver them all. “This is a real problem with some people who use supplements,” offered our Research Editor. “It looks like you have to take 11 tablets and capsules twice daily. That’s a lot to ask of the customer.”

“The only criticism I have for this is that there are quite a few pills,” one user explained.

Another didn’t like the volume, “Just massive pill. And too many pills.”

The pill problem was a lesser issue for some customers.

One said, “The tablets aren’t actually that big at all.”

“Tons of pills but it’s easy to get used to,” said another.

Animal Pak Effects – “Not What Was Expected”

We’re not sure what customers expected from Animal Pak, but for $25 or more a week, it’s clearly something more than they got, in some cases.

“Didn’t feel anything or perform better or worse,” one user claimed.

“The product is not effective in any way, shape, or form – I noticed zero difference before and after using it,” said a customer.

Some didn’t see these issues as being a problem.

“I don’t feel supercharged when I do take Animal Pak. But I do feel undercharged if I forget to take it,” reported one buyer.

Yet another said, “Gives subtle but steady energy without jitters or stims.”

During years of research we’ve picked up something here and there. It’s the small things, like unmet expectations, that ruins a user’s chance of long-term success. If Animal Pak doesn’t deliver, the customer will not likely keep paying the high price.

The Science – “Any Real Justification?”

Animal Pak is ultimately a multivitamin, but it’s aimed at athletes. The extra complexes are perfect for these people, but the average dieter doesn’t necessarily need it all. Science does support taking vitamins, but getting them from food is always a better option. At DietSpotlight we need clinical research to support spending more than you would on the same product from the competition. We’re not sure this is the best option for the average person.

The Bottom Line – Does Animal Pak Work?

Are we racing out for Animal Pak multivitamins? Well, the formula is definitely far superior to traditional vitamins, but there’s a little too much in there for the average dieter. That’s not to say the body won’t use it for what it’s designed, just not to the extent the athlete’s body will.

If you are looking to add a multivitamin as support during muscle-building, that’s a good idea. But, we suggest adding a clinically tested supplement designed to spark metabolism – something the customer can make use of.

Among the best products we’ve seen this year is our supplement called Pronabolin. It consists of nine ingredient, all clinically-tested, with results often found in journals such as The Aging Male.

Plus, we’re so confident you’ll love our supplement, that we’re offering multiple-bottle discounts and a 120-day money-back guarantee, which is a great sign.

What You Should Know About Animal Pak

Stacking is a major aspect of bodybuilding. Supplements are often offered by one manufacturer with the idea of including all, safely, into one supplement routine. Universal Nutrition has included Animal Pak as the foundation for their Animal Stack. Animal Pak is a multi-supplement that includes many common vitamins and nutrients with a boost for people trying to increase muscle size.

The official website is complete with ingredient lists and ordering. Universal Nutrition also includes a long list of supportive research links for consumers who want to read more about the ingredients used in each of the supplements found online. Aside from this product, Testo RPM is a testosterone booster that contains tribulus terrestris and horny goat used to get the most out of your workout.

List of Ingredients in Animal Pak

Animal Pak Product Features

Animal Pak is a multi-vitamin style supplement created for bodybuilders. Much of the ingredients in the mineral and mega-vitamin list can be found in common, over the counter, vitamins. The remaining ingredients, however, are included with weight lifting in mind.

Amino acids are the functional building blocks of new muscle. While many other body building supplements will include amino acids, there are rarely any side effects from taking them multiple times a day.

Performance optimizers will not help someone trying to lose weight. These ingredients are included to help the muscle make the most out of every movement from lifting off the bar to complete a routine set of repetitions.

Antioxidants and general support includes ingredients to aid cells in recovery. Weight lifting will greatly damage muscle cells because out of destruction, new larger muscles are formed. Bone support is equally important as heavy weights can wreak havoc on joints and bones. The ingredient list is rounded out with a digestive complex to ensure the body is able to use every other ingredient to the fullest.

Animal Pak retails for $51.95 for 44 packs. One pack is taken daily to optimize the body for weight lifting. Though this is a bodybuilding supplement, there are no ingredients that will render weight gain and thus the supplement can be safely used by people trying to lose weight.


  • The supplement can be ordered online.
  • A complete list of ingredients is included on the website.
  • Anyone can take Animal Pak.


  • Animal Pak is priced higher than other multi-vitamin supplements.
  • Some of the ingredients would not be useful for someone simply trying to lose weight.

Animal Pak Conclusion

Universal Nutrition does a great job of offering a complete list of supplements for the bodybuilder. However, these supplements are mostly useful for a small portion of the population. More people are trying to lose weight than build muscle and thus the audience for the supplements is very narrow.

Animal Pak Side Effects:

We’ve heard the talk about Animal Pak dietary supplement, so we decided to pay close attention to Animal Pak side effects. (Feel free to read our full Animal Pak review.) We’ll concentrate on ingredients and scientific research. Furthermore, we’ll analyze hundreds of consumer comments. Then we’ll condense the info and give you the bottom line.

What You Need to Know

Animal Pak is a dietary supplement containing B-vitamins, amino acids, antioxidants and digestive enzymes, among others. The recommended serving is two packs or 22-pills, which supposedly increases athletic performance and strength. One of the benefits is it’s easy to take with you.

The supplement, introduced in 1983 by Universal Nutrition, appears to be affordable, a good start. Customers can purchase Animal Pak through trusted retailers and at health stores. We like that we located some positive customer comments and the length of time the company has been in business, but read on…

Heart Palpitations – Pounding through Your Chest?

The first concern about Animal Pak ingredients is reported heart palpitations. “There are far too many supplements on the market to choose from to settle for one that causes a negative reaction,” said our Research Editor.

“This supplement dropped my heart rate from 40 and elevated it to 120 in seconds without exercising. Felt huge discomfort, gave me high blood pressure and fainting feeling lasting for more than 2 hours,” commented a customer.

“I just started taking Animal Pak. Both times I’ve taken it have been on an empty stomach, 30 min before my work out. Both days my heart has felt like it was going to explode,” reported a consumer.

FDA Warnings

In March of 2005, the Food and Drug Administration contacted Universal Nutrition relating to supplements found at a manufacturing facility. The warning was about the mislabeling of products. The formulas contained less ingredients than listed on the label.

Lethargic – Is it Slowing You Down

One of the major Animal Pak side effects noted by customers was lethargy. “The first dose I had noticed I was feeling a slightly upset stomach. A few days into it, I had noticed I was feeling quite lethargic and feeling “off”. I had full blown cold symptoms. Runny nose, cough, congestion, etc.,” stated a customer.

“I bought these to step up my workouts, and now have trouble dragging myself to the gym, or even taking a jog around the block – have been taking for about a month now…they’re killing my energy levels and taking me in the opposite direction I wanted to go,” commented a consumer.

“After taking this for about 3 weeks, I am usually dragging by 2:00 on the Animal Pak,” said a user.

It’s based on our experience researching supplements that we conclude, it takes something small, like lethargy, to put a damper on long-term success. If Animal Pak makes you sluggish, why would customers keep buying it?

The Science

When we visited the official Animal Pak website, we noticed scientific studies, but the research didn’t paint the complete picture. They looked at individual ingredients, not the product as a whole. We also located science to tell a different story. One used by Universal Health disproves the effectiveness of one of the key ingredients. According to the Department of Bioorganic Chemistry, Facility of Chemistry, Wroclaw University of Technology, “For other conditions, such as fatigue or improving exercise performance, L-carnitine appears safe but does not seem to have a significant effect.” At DietSpotlight, finding science to support claims is a major factor. If there’s no evidence a product is effective, we have concerns.

The Bottom Line

Our research has taken us to a conclusion. We like that we found some positive customer comments and that the company has been in business for more than 30 years, but we can’t recommend it because of the lack of scientific research offered up by Universal Nutrition. Plus, we’re concerned that Animal Pak side effects could lead to larger issues.

If you’d like to shed those extra pounds, we recommend a product supported by published clinical research, with no reported negative side effects.

One of the best supplements we’ve researched this year is one called Leptigen. The product contains a four-ingredient proprietary blend, which has been shown in published clinical studies to help promote fat loss and ignite metabolism. No one is reporting adverse side effects and from comments on the web, people are seeing great results.

The company that makes Leptigen is so confident in the supplement that they’re offering a Special Trial Offer, nice touch.

Am a lean Guy and very desperate to gain mass (huge)can animal pak help?

Maribel (Editor)

Hi Rex! Unfortunately, we could not find any research connecting multivitamins to muscle mass growth.


If you just start to workout id say wait about 3 mouths then buy animal pack for now what you need is good whey protein.

  Multi vitamin

should I stop taking a multi vitamin if I am using the animal pak vitamins? what about vitamin C?

Maribel (Editor)

Hi! Because of possible interactions with other products, please make sure to consult with your physician before taking this product.


It doesn’t hurt to take them! I take the animal pak and an A.M. And also P.M. Vitamins. Mainly read ingredients and what’s n there! If you don’t really eat enough fruits and veggies it’s good to take something to replace it.


Don’t forget you can overdose yourself with vitamins and because of taking that amount of tablets your kidneys are under prssure to flush them out. Drink plenty of water.Urine turns yellow

Dale (Verified User)

Any bloating from all the vitamins?

Good to use even though I just want to bulk up and still be flexible?

Maribel (Editor)

Hello Dale. Some customers have complained of stomach issues while using Animal Pak, but if your bloating is severe, discontinue use and seek medical attention. To answer your second question, Animal Pak sells a variety of different supplements whose purposes are equally as different. We suggest using an exercise plan that matches your goals, even if you choose to take Animal Pak. However, we don’t think there would be an issue using Animal Pak while working toward these fitness goals.

Ezra Berry

I’m 15 and play Football, Wrestle,, and play Baseball. I’m in pretty good shape now but I want to be a little stronger and better looking. I’m not trying to be huge. Can I take Animal Pak? Notice I do lift with Wrestling.

  Can it be used with animal pack?

k so if im taking bcaas at the moment and stacking it with creatine.. if i start taking animal pak do you think it would be a good idea to get off of the bcaas or stay on them both?

Maribel (Editor)

Hi! Because of possible interactions with other products, please make sure to consult with your physician before taking this product.


I’d lay off the creatine when taking it tbh


incorrect. THere’s no reason those can’t be taken together.

  what are side effects

im 15 and my mom doesn’t want me to use protein powder and stuff like that. Is this a generally good alternative? like thats healthy. what are side effects of it? pros cons of the vitamins itself

Maribel (Editor)

Hello Patrick. This product is to be only used by adults 18 years and older.


No it’s not an alternative. Protein powder is a protein supplement to aid the repair of broken muscle fibres which means building muscle mass. Animal Pak is a set of vitamins to help your body cope with the strenous amounts of exercise. You won’t be doing professional bodybuilding so no you don’t need it.

  Want to take twice a week

Since i’ll not be training for professional. Can I take animal pack just twwice a week

Maribel (Editor)

Hi KC! Animal Pak mentions that it’s okay to decrease dosage to just once a day. Any lower than that and you may not see the results you’re looking for.

  Can I take other medication?
Pete (Verified User)

I take Crestor for my cholesterol.Can I take Animal Pak while on the Crestor?Any interactions?Thanks.

Maribel (Editor)

Hi Pete! Because of possible interactions with medications, please make sure to consult with your physician before taking this product.


If you read the warning on the product it says not to take it if you have problems with choleaterol


Nothing compares to animal pak in that it provides literally everything you need if you’re seriously training. You’re not necessarily going to feel any real affects. Although it did give me a considerable increase in muscular endurance when training. You’ll see the affects in strength gains and muscle build.
It’s also very important to add which I thought this article would include that the B-6 daily value is 9000% which is way to high in a vitamin shown to increase risk of serious heart, nerve and prostate issues when taking in excess.
Also I think it’s vitamin A, B, C and K but the vitamins are fat solulable so you have to cycle off for periods of time because that can become toxic in stored fat

Pedro m

I have seen results time and time again with Animal pack. It is not muscle helium so it takes a little longer than your usual supplement to see gain but the gain you get to keep for a long time, didn’t work out for 2 years and many people though I was hitting the gym.on the regular.

You should combine it with a consistent high natural protein diet, plenty of fluids and rest. By consistent I mean everyday and don’t intake all your protein at once as your body can only absorb so much and waste the rest, so every couple hrs I take some. I don’t get extra energy from it but it helps my endurance on rigorous sessions. I only take half dose too . Hope this helps.

Shehryar Khan

I do not understand what kind of effect do people look for from a Multivitamin supplement? It is not a stimulant complex (To give you a strong boost of energy nor is it a steroid to give you massive muscular gains in little time) Multivitamins are more like an “Insurance” towards your over all health and are in no way designed to treat, cure or prevent a disease. The best a Multivitamin such as Animal Pak can do is give your immune system a 5 to 10% boost and MAYBE JUST MAYBE all that Vitamin B will help your metabolism perform SLIGHTLY above average. And remember, it is a SUPPLEMENT hence should be treated as one.

  I feel more awake !

He isnt too young he is just at the age to be workingout and taking as much vitamines and protein becouse his body is growng now more than it will ever do soo the fast rate he is growing plus if he is working out all he needs as supplements are multivitamines and whey protein.Animal pak is better than any other multi vitamine soo why not take it.


He is too young for this.it eveb gives yu a warning on the container and than on the metal seal yu take off when yu first buy it.it is possible it can effect him in a negative way.he isnt fully developed and some of those chemicals may not help.it even asks yu to ask a physician if its ok to take it

  Could it gain some muscle?
Anna (Verified User)

I’m a distance runner running up to 50 miles a week at very high intensities. I was recommended animal pak (in a half dose) to help repair muscle I am constantly tearing down in training-especially the 15+ mile runs. Is this a good choice? I’m not taking them with the goal in mind of putting on muscle weight, just improving muscle recovery and endurance. Any comments?


Is animal pak can be taken over cassin??

  Hated the product.
karl jones (Verified User)

I used Animal Pak for the last 6 months and have not noticed a difference in my overall performance in the gym. My trainer (whom I use 3x per week) recommended the Anabolic Stack from the Dr. Max Powers brand – its a combination of supplements you take all together, and it has all the ingredients need to boost my workout. I’ve probably taken the Dr Max Powers Anabolic Stack for two years (off and on), its a bit pricey to take it year round but you do get what you pay for. Probably the best thing I have taken with it to see actual results in strength (prob about 10% increase in strength in the past month).

  Trying to grow big

it takes how long for me to grow big


Deppends on your workaout program and your diet.If you have good diet and you workout 5-6 times a week you will see results in about 3-4 mouths.For you to get big muscles it take years.

  I'm glad I used this product
DC (Verified User)

So I have been using Animal Pak by Universal for a few months, but then I switched to the Dr. Max Powers Anabolic Stack now and am really pleased by the switch! The Max Powers Anabolic Stack is better because I wanted a multi vitamin for someone who was in the process of getting lean and putting on muscle mass.

After much deliberation I settled on the Anabolic Stack. I read a lot of reviews online praising how balanced it was. I also talked to some personal trainers at my gym and they too recommended that I try it. The pills themselves are packaged together so I do not have to carry around a bunch of bottles. This makes it very convenient to take them no matter where I am.

The price for 30 days worth of pills is also not too bad. The major downside to Animal Pak is the size and number of pills, but the Dr max Powers Anabolic Stack makes me feel like they are better for me because they are not undersized to be more appealing.


Animal pak is a multivitamin not an anabolic stack theres a big difference….lol.. one is just vitamins the other is alot different it’s anabolic so how can compare it….lol sounds like an add just to buy Dr anabolic stack…lol…no disrespect buddy…
