Advocare Mass Impact Is A Dud


Here is a review of Advocare’s Mass Impact, part of their Performance Elite line. The product has the word MASS in it so right away we know this is going to be good.



Quick Look


The product calls itself a multi nutrient amino acid supplement with the key benefits being aiding in muscle building, supporting muscle performance and helps increase physical endurance. Mass Impact contains 3 grams of creatine monohydrate, 2 grams of leucine, 1 gram of glycine and 500 mg of glutamine in the form of Sustamine. The product comes with 50 servings with a retail price of $72.95 (Distributor price: $58.36 / Advisor price: $43.77).



Creatine/Claim


“Mass Impact™ helps maintain ATP levels for cellular energy and to preserve muscle glycogen, which promotes muscle mass, volume and strength.”

The products first ingredient is creatine monohydrate with 3 grams per serving. Recommended doses of creatine can be found anywhere from 2-5 grams with 2 being the bare minimum to maintain average stores and 5 being the most common to keep creatine stores elevated. Creatine is the most studied supplement to date with its effects on power output and muscle endurance (through storing phosphocreatine) are well supported by the scientific consensus. So, their claim is not false with what creatine does but they do leave some important factors out. Creatine needs to be supplemented every day to keep levels elevated (to get the effect). Mass Impact only has 50 servings, so the product will only last under two months which is a short amount of time when you are taking it daily, compare this with 200 servings that can be commonly found in your local Vitamin Shoppe at a lower price as well. It seems that they try to sell you this as a better quality creatine when in fact it is not, creatine monohydrate is creatine monohydrate.


Sustamine/Claim


“Sustamine supplementation results in improved performance and promotes protein synthesis, inhibiting muscle breakdown and reducing muscle tissue damage.”

Sustamine is a trademarked product that is a specific blend of l-glutamine and l-alanyl, Im first going to talk about glutamine and then tackle sustamine. Glutamine is a well known product in the supplement world since not to long ago (and still sometimes today) it was told to be the anabolic messiah. So far there has been no evidence of glutamine supplementation to increase muscle building in healthy individuals, I say healthy since the only benefits of glutamine supplementation have been noticed in severe physical trauma patients(burns or knife wounds) and disease states that are muscle wasting (AIDS). The average persons protein intake will satisfy their glutamine needs and this is especially true to people who are into fitness since most of them over eat protein to begin with. So as to the claim that this product will be “inhibiting muscle breakdown and reducing muscle tissue damage” seems to be a very bold stretch.


Now lets look at Sustamine as a whole, I could not find to much on it and unfortunately only found one study that I could look at the full text (1). The study looked at “fluid regulation, immune, inflammatory, oxidative stress, and recovery was examined in response to exhaustive endurance exercise, during and in the absence of dehydration”, the study size was 10 men and a the conclusion was, “Results demonstrate that AG(Sustamine) supplementation provided a significant ergogenic benefit by increasing time to exhaustion during a mild hydration stress. This ergogenic effect was likely mediated by an enhanced fluid and electrolyte uptake”. So it seems that in this one study that they saw a significant difference in time of exhaustion (I am not sure if it is clinically significant but this is just a overview), the kicker is though that the trial that saw the biggest difference was taking 0.2 g·kg of Sustamine. With the average body weight being  77.4kg this comes out to be around 15.5 grams of sustamine that the study above worked with. This product only has 500mg per serving.


Other Amino Acids/Claims


“Several other amino acids found in Mass Impact™ help optimize fat cell and muscle tissue communication to promote muscle leanness, activating cell signaling pathways for muscle growth.* They also contribute to muscle repair and strength”

So what we have here is 2g of leucine and 1g of glycine, now the above claim is true amino acids help with muscle growth, repair and strength, but we get amino acids from eating protein through our diet, and as I stated above most people who are into fitness eat well over enough protein. Take this into perspective to get the above aminos all you would have to eat is approximately 3.5 ounces of chicken, 3.5 ounces gives you 2.3 grams of leucine and 1.5 grams of glycine. It seems they try to hype the amino acids in Mass Impact to be different or better then what we get through our diets, but that is just false.


Conclusion

This product is a highly overpriced creatine supplement, as I have stated the Sustamine is more then likely to have no affect on the individual taking this (unless you take about half the container) and the miniscule amount of aminos would not have any effect on someone who eats adequate amounts of protein. If your goal is to increase muscle size and or improve performance getting enough whole protein should be your priority over wasting your money on supplements. Now if you are looking for a creatine supplement then I would suggest you to purchase creatine monohydrate by itself, 2.2 pounds of creatine can be purchased for 20 dollars with 200 servings (5g per serving) the cost per serving comes out to be .10 cents. Now compare that to Mass Impacts 1.45 (at 72.95 price) per serving. Save your money and do not buy Mass Impact.

Advocare Spark A Bunch of Hype


There seems to be a lot of noise about how amazing Advocares products are as of late. I will be doing a series where I break down some of Advocares more famous products as well as going over any published research done on the product and giving a scientific opinion (as unbiased as I can) on it as well as my own opinion (more biased) with practical use. Here is my first review and it is on Spark the energy drink.



This is the only study that I found that is actually published through a journal on Advocares Spark energy drink. The study wanted to see the effects of spark during repeated sprint performance and anaerobic power on trained college athletes. Here is a link to the study Spark Study



Overview

20 NCAA div 1 football players were grouped into two groups (2 groups of 10). The study used Running-based Anaerobic Sprint Test (RAST) to measure anaerobic power. Both groups would come in fasted (had not eaten since they awoke) and ate a 400 kcal breakfast with 70 g of carbs. After Eating their breakfast the participants were randomly assigned to one of two groups (AdvoCare Spark or placebo) and 60 minutes after consuming their drink they went through RAST. Then 7 days after the first test day the participants came back and the groups went through the same procedure but switched what drink they had.



Limitations

The Study was only looking at acute effects of Spark not long duration. The way they assessed caffeine tolerance was self reported which athletes could given false numbers on his or her caffeine score. Other then that I could not find any other limitations on this one study but I am open to input.



Strengths

This double-blind, randomized, crossover design is the only one to test the formula of spark on trained athletes to see if it does help acute intense exercise performance. They did put in the effort to make sure that each athlete was running on the same amount of fuel with match breakfast and carb intake across the board. They also made sure that the athletes caffeine history was evaluated by assigning a caffeine score to each athlete based on his daily consumption of caffeinated beverages during the month before the test.



Results

This single study did not show a significant difference between the controlled group and placebo in run time and anaerobic power.


"The repeated-measures ANOVA showed no statistically significant difference for the main effect of the beverage treatment (energy drink vs. placebo) for either the sprint time (F = 3.06, p = .097) or anaerobic power (F = 3.84, p = .066), indicating that the energy drink did not affect performance."


However the study did show some difference from athletes not habituated (regular use) to caffeine were more likely to improve from the energy drink than those who regularly consumed caffeine.


“There was a significant interaction effect between caffeine use and the beverage treatment for both sprint times (F = 4.62, p = .045) and anaerobic power (F = 5.40, p = .032), indicating a confounding effect such that athletes not habituated to caffeine were more likely to improve from the energy drink than those who regularly consumed caffeine.



My Comments/Opinion

I believe this study's results to be aligned with my own opinion on the product… its a bunch of hype with no bite. Twenty trained college athletes took the product and there was no significant or even practical difference between the placebo or Spark group. I will admit that this is only one study and making an absolute statement like that is wrong but I am not making my opinion on just that study alone, I am making my opinion on the body of evidence that we have on the three most prevalent ingredients in spark (Caffeine, Taurine and L-Tyrosine). 


There is evidence of the notable effects of caffeine on cognition, adrenaline, anaerobic capacity and power output but the effects are not ground breaking and each effect does seem to dwindle down after tolerance builds up with the frequent use. Also sparks caffeine dose is greatly underdosed (a overall theme with most supplements) with only 120mg per serving, where the research right now shows most performance advantages comes from doses above 500mg per serving! 


Taurine as of right now has not been shown to have any effect of athletic performance but has shown to been helpful with blood flow in type 1 diabetics. Does this mean that taurine is useless to take in? As of right now unless you have a deficiency (if you eat whole protein sources you are fine) and or are type 1 diabetic then the supplementation has no use that we know as of right now, but this can change with more research done. Even if Taurine did have effect I do not think the dose of 200mg will have any effect since when it does make a difference it is in the range of 500 -2,000 mg.


L-Tyrosine has promise in the areas of improving cognition during acute stressors but like the other two ingredients (and most of the others in spark) it is underdosed. Spark contains 500mg per serving and studies show a much higher amount to see any effect from it, around 100-150mg/kg bodyweight this is a dosage range of 9-13.5g for a 200lb person and 7-10g for a 150lb person.


Final Words

Do not buy this product it is way to underdosed and over priced. Here is another objective review on spark by Greg Farris that goes more into the dosing of the product I would advise you to read this as well
