High Impact Plant Protein is a protein supplement from the Power Life brand, which is owned by celebrity trainer and founder of “P90X” Tony Horton. The brand claims that this supplement can “support your strength, and support the preservation of lean muscle.”
Does does High Impact Plant Protein contain an effective protein dose, or are these just marketing claims? What are the other ingredients in this supplement and are they healthy or unhealthy? How do real users rate and describe the effects of this protein powder? And which retailer sells it for the best price?
In this article we’ll answer all of these questions and more, as we analyze the ingredients in High Impact Protein based on medical studies to give our take on whether this supplement is likely to be effective for muscle growth, or if it’s a waste of money.
We’ll feature unsponsored customer reviews of the product, and provide a cost comparison that shows whether Power Life’s protein powder is more or less expensive than most other protein powders.
High Impact Plant Protein contains a large number of ingredients, so we’ll break our ingredient analysis into sections. The ingredients in the Plant Protein Blend are shown below:
VegiZest is a trademarked protein blend that includes ingredients like fava bean protein and pea protein.
We have no issue with this ingredient, although the total protein dose per-serving is only 15 grams (g).
We typically recommend protein powders that provide at least 20 g of protein per serving, because a 2013 clinical trial suggests that this is the maximally-effective dose threshold for building muscle after exercise.
Protein dosage is less of an issue with single-ingredient products (where protein is the only active ingredient), because servings can easily be adjusted up. It’s more of an issue with products like High Impact Protein that contain many other active ingredients, because it’s unclear whether or not it’s safe to take more than one serving daily.
myHMB is a trademarked blend of calcium and beta-hydroxy-beta-methylbutyrate that was shown to improve strength in older adults in a 2020 clinical trial.
However, taking supplemental calcium may also increase health risks, and one serving of High Impact Plant Protein provides 41% of the Daily Value (DV) which is not an insignificant amount.
A medical review published in the Journal of Internal Medicine reported that calcium supplementation can increase heart attack risk by 20-40%.
DigeZyme is a trademarked digestive enzyme mix, and we don’t understand why so many protein supplements contain supplemental enzymes. We haven’t seen any clinical evidence that enzyme supplementation improves physical performance or enhances protein uptake, nor does Power Life cite any on their product page.
The vitamin and mineral blend in this protein powder is shown below:
Chromium is included at a dose of 571% of the DV.
The brand fails to cite any clinical evidence suggesting that taking such a high dose of chromium on a regular basis is safe.
A clinical trial on chromium and muscle gain concluded that “routine chromium supplementation has no beneficial effects on body- composition change or strength gain in men.”
Vitamin D3 is also included at a high dose of 100% DV, and many consumers obtain vitamin D from other sources as well including sun exposure, food and other supplements and multivitamins.
The inactive ingredients in this protein powder are shown below:
Natural flavor is the only questionable ingredient in our opinion. As we documented in our Orgain protein powder reviews article, at least one medical review suggests that flavoring additives and their metabolites may be toxic.
Overall, we consider High Impact Plant Protein potentially effective for muscle growth, but we do not recommend this supplement overall due to the inclusion of natural flavor, the high chromium and vitamin D3 doses and the inclusion of added calcium.
This is a below-average protein powder formulation in our opinion, and when compared with the average brand reviewed to date on Illuminate Health.
But how do real users rate and describe the effects of High Impact Plant Protein? We’ll feature some unsponsored customer reviews in the next section of this article.

Our Clean Protein Picks
Bulletproof Collagen Protein is our top overall protein powder pick, and costs only $1.32 per serving at the time of updating this article.
The main reason is its formulation: Bulletproof's protein powder only contains one single ingredient: collagen protein sourced from grass-fed animals.
As the core structural protein in skin, supplemental collagen is clinically shown to reduce visible signs of skin aging like wrinkles, which is a secondary benefit not offered by other types of protein like whey protein.
Promix Whey Protein is our top whey protein powder, and costs only $0.93 per serving at the time of updating this article when you purchase the 5 pound bag.
This brand uses grass-fed whey protein and no sweeteners or flavoring additives. Whey protein is a "complete" protein, meaning it contains all nine essential amino acids.
Complement Organic Protein is our top vegan protein powder.
The only ingredients in this protein powder are a blend of nutritious plant proteins: organic yellow pea protein, organic pumpkin seed protein, organic almond protein, organic sunflower seed protein and organic chia seed protein.
All three of the products mentioned in this section are entirely free of additive ingredients that we consider to be unhealthy or unsafe.

Real Customers Review High Impact Protein
Amazon is a better resource for honest customer reviews than a brand’s website in our opinion.
High Impact Plant Protein has been reviewed over 2,900 times on Amazon with an average review rating of 3.8 out of 5 stars.
The top positive review from a verified purchaser comes from a user named “Karen H.” who gives the product a 5/5 rating and claims that it’s well-formulated for vegans, taste good and even reduced appetite:
“Great product. I've noticed that I experienced no digestive problems while using it. It has a nice mild taste (at least to me). It also strangely cuts my appetite. It's the benefit of getting more protein while eating vegan/vegetarian and getting in badly needed Vitamin D3.”
The top negative review from a verified purchaser is written by a user named “sirmichael” who gives the product a 1/5 star rating and considers it too expensive:
“I’ve tried a lot of really good vegan protein powders. This is the most expensive per scoop I’ve ever purchased. I should have looked closer at the cost per serving. This one is extreme. 15oz is a small tub. For $60 it’s just too much. Do some research on HmB and you’ll find it’s pretty weak evidence of actual benefits.”
Power Life has an average review rating of 4.7 out of 5 stars on the Better Business Bureau (BBB) website.
High Impact Plant Protein has an average review rating of 4.1 out of 5 stars on Google.
