What is High Impact Whey Protein?

High Impact Whey Protein, by Tony Horton, is designed to help promote muscle strength and gains in muscle size.

Dietary protein supplementation, combined with resistance training, has developed into a common practice seen in athletes and recreational exercisers, to induce gains of muscle mass and strength.

A decrease in skeletal muscle mass occurs by 1-2% each year after the age of 50, a process otherwise known as sarcopenia.

A low intake of dietary protein may also contribute to age-related muscle loss, suggesting that increasing protein consumption may prevent further loss.

Performance of heavy resistance exercise and high-intensity interval training can stimulate an increase in muscle protein synthesis (MPS).

However, intense unaccustomed exercise may also cause muscle damage, which results in muscle soreness, a temporary decrease in muscle force, and edema.

High Impact Whey Protein is a non-GMO, hormone- and antibiotic-free dietary protein supplement.

This supplement also contains whey protein, HMB, vitamin D3, and digestive enzymes.

According to their website, High Impact may also support lean muscle mass and nutrient absorption, and smooth digestion.

High Impact Whey Protein is recommended to be consumed in the morning to feel more energized and fuller throughout the day, or after exercising to nourish your muscles as a way to maximize benefits.

In this article, we’ll share our review of available studies to determine if there is any merit to the brand's claims.

Proposed Benefits: Do They Work?

To use High Impact Whey Protein, mix 1 scoop in 80 ounces of water or with your favorite smoothie. Each serving contains 15 g of:

  • Whey protein
  • Beta-Hydroxy-Beta-Methylbutyrate (HMB) and Vitamin D3
  • Prohydrolase
  • Chlorella
  • Chromium

However, the company does not provide the exact dosage amount of each ingredient on the supplement's nutrition label.

The Muscle-Building Effects of Whey Protein, Vitamin D3, and HMB

Age-related changes can lead to impairment in muscle balance. Through decreased levels of physical inactivity, older adults may be more resistant to building muscle, a condition known as anabolic resistance.

Vitamin D, otherwise known as calciferol, is essential for bone health due to its role in regulating calcium.

A review of studies was done to assess the effects of vitamin D supplements on muscle function, including muscle strength, muscle mass, and muscle power.

Based on the review’s principal findings, results from the 29 randomized control trials have shown a small but positive significant effect of vitamin D supplementation on muscle strength.

However, no significant effects of vitamin D were found during the review of studies.

HMB is a bioactive metabolite formed from the decomposition of leucine, an essential branched-chain amino acid. HMB also plays a crucial role in regulating muscle protein anabolism.

Compared to exercise alone, HMB supplementation was shown to have no or a reasonably low impact in improving body composition, muscle strength, or physical performance in a recent systematic review of 10 randomized control trials.

The muscle-building effects of HMB may favor the younger and highly trained population.

A 12-week randomized study was done to verify the effects of HMB supplementation on physical capacity and body composition in highly trained athletes.

The study results indicate that supplying a dose of 1250mg Ca-HMB can promote changes in body composition and stimulate an increase in aerobic and anaerobic capacity in highly trained combat athletes.

However, a recent review suggests that the recommended daily allowance (RDA) for protein is inadequate, and the timing and distribution of protein consumption throughout daily meals is just as important as the total quantity.

Chlorella is proposed to offer antioxidant benefits. The development of oxidative stress increases with age and plays a role in age-related muscle atrophy.

A study in mice found that long-term consumption of chlorella has the potential to prevent age-related muscle atrophy.

Prohydrolase is an enzyme that helps with the absorption of nutrients such as protein and improves digestion.

A study found that a dose of 250 mg of prohydrolase did not contribute to the additional muscle-building capability of whey protein supplementation when compared to the placebo.

Effects on Muscle Recovery

A rise of skeletal MPS is defined as anabolism, and/or reduction in skeletal muscle breakdown is defined as catabolism. A positive NPB can increase skeletal muscle mass, and a negative NPB will result in a loss of skeletal muscle.

Pre- or post-exercise ingestion of protein can increase MPS and result in a positive NPB.

Research suggests that protein supplementation can enhance skeletal muscle hypertrophy with the performance of chronic resistance training.

A study was done to determine if whey protein ingestion can improve whole-body net protein balance and recovery of exercise performance during overnight and 24 hours recovery after whole-body resistance training in 12 men.

The participants were required to ingest 25 g of whey protein immediately post-exercise and again the next morning (approximately 10 hours of recovery.)

The study's findings show that protein supplementation at 24 hours was not only able to enhance whole-body net protein balance but also be used to improve acute recovery of exercise performance after strenuous resistance exercise.

Safety

Generally, whey protein supplementation is safe to use and is even more readily available through a well-balanced diet.

Those who regularly perform in various forms of physical activity, such as resistance and aerobic training may benefit by doubling their Recommended Dietary Allowances (RDA) for protein.

As mentioned earlier, the performance of strenuous training can affect NPB, and adjusting protein supplementation may ensure the preservation of muscle mass and strength.

For adults, the RDA for protein is 0.8g protein/kg body weight daily.

The Cost

High Impact is currently only available from the High Impact website.

It is offered in chocolate or vanilla flavors and ships free at the following prices:

  • $69.95 for 1 jar
  • $188.85 for 3 jars
  • $353.70 for 6 jars

While you’ll save the most by purchasing 6 jars, keep in mind a single jar contains 15 servings. You’ll need 2 to get you through the month.

They also back every purchase with a 90-day guarantee. To process your return, call 855-462-2496 or email support@mypowerlife.com.

What Are The Alternatives to High Impact Whey Protein?

Searching Google or Amazon of whey protein supplementation will reveal a variety of options.

Ghost ® Whey Protein is an available alternative that offers 26 grams of protein per serving and is a much cheaper option as you will be able to get up to 26 servings per bottle.

It is highly recommended that you attempt to obtain your dietary protein naturally through a well-balanced diet. Tony Horton’s High Impact Whey Protein uses an 80-85% grass-fed whey protein. The alternatives to this include poultry, beef, eggs, and seafood.

Pros and Cons

Pros
  • Ingredients contained in High Impact Whey Protein has been studied extensively.
  • Whey protein, along with HMB and vitamin D3 have the ability to improve muscle mass.
  • When taking within 24-48 hours, whey protein can influence muscle recovery
Cons
  • Expensive when compared to alternative whey protein supplementation
  • Not an effective option available to promote weight loss
  • The ingredient dosage amount contained is much less compared to similar supplementation in studies.

The Bottom Line

Whey protein supplementation has been studied extensively to support the claims made by Tony Horton’s High Impact Whey Protein product.

As a dietary supplement, whey protein offers the same benefits as plant-based proteins to provide individuals with a vegan or vegetarian option. Further, no real study or product is held higher than one another regarding the purported benefits.

Research has provided that HMB may have beneficial effects that will influence muscle building capacity in highly trained athletes.

Along with muscle building capacity, whey protein supplementation may help with recovery from strenuous exercise and further indicates that the timing of protein ingestion is just as important as protein consumption.

High Impact Whey Protein is generally safe, and excess protein consumption rarely leads to adverse effects.

As always, speak with your physician regarding any planned changes you want to make with your diet.
