Fitness Quest Timed-Release Protein

There’s so many protein products on the market. How do I know which is best?

Fitness Quest Timed-release Protein provides research-proven benefits for sports and fitness, weight management and metabolic health.

Why Supplement Protein?

All protein, whether plant, animal, fish or fowl, is broken down by the digestive system into building blocks called amino acids. Amino acids are required for all repair functions, as well as growth, and can even be used as an energy source.

Supplemental protein can be important for people who want to build muscle.

  • Body-builders
  • Athletes

Protein also helps to balance blood sugar and is the major influence on hunger satisfaction or satiety. Thus, supplemental protein can also be important for:

  • People wanting to lose weight
  • Those using intermittent fasting to improve metabolic health.

Since digestive efficiency varies from person to person and declines with advancing age, supplemental protein can also be important for:

  • Men and women over 50
  • People with digestive disorders
  • People preparing for and recovering from surgery

Why Timed Release?

In terms of digestive efficiency, there are advantages to delivering protein gradually compared to a large amount all at once. Timed release is also better for bodybuilders and athletes who need amino acids over a 3 to 5 hour period for full recovery.

How Timed Release?

Fitness Quest Timed Release Protein consists of four phases:

Phase one: Whey Protein Isolate (WPI).

WPI is the most efficiently digested protein, making amino acids available quickly. [1,2] Each serving of Timed Release Protein provides 21 gm of whey protein isolate.

Phase two: Soy Protein isolate (SPI)

SPI is the highest quality protein derived from soybeans, and has been shown to support muscle gains after exercise equal to animal protein. [3] It is a slower digesting protein, making it ideal for a timed release strategy, and most important, acts in synergy with WPI.

SYNERGY Explained: There are 22 amino acids used by the human body. Nine of these cannot be synthesized by the body and must be obtained from dietary sources. Both soy and whey protein are “complete” proteins, meaning they contain all nine essential amino acids. However, they differ in their relative concentrations of the essential amino acids. Whey isolate is higher in leucine, isoleucine, methionine, and lysine, while soy protein is higher in arginine, phenylalanine and tryptophan. [4] Each serving of Timed Release Protein provides 5gm of soy protein isolate.

Phase Three: Sacha Inchi (Plukenetia volubilis) Seed Protein

Sachi Inchi, also known as Inca Nut, is native to the Amazon tropical rainforest. The defatted, dried and ground seed is about 60% protein, and most important, about 64% of that is L-Leucine, the amino acid with the greatest muscle synthesis activity. [5] Including Sacha Inchi provides three important advantages:

  1. Slower digestion compared to WPI and SPI provides amino acids hours after ingestion.
  2. Boosts the BCAA level to 6.7 gm per serving
  3. Adds a nut-like flavor

Each serving of Timed Release Protein provides 3 gm Sacha Inchi protein

Phase Four: Fibersol® Soluble dietary fiber

Soluble fiber contributes to satiety or hunger satisfaction, and extends the timed-release feature of this product. [6] Unlike dietary starch, this patented soluble fiber has a beneficial effect on balancing blood sugar, and is classified as “resistant starch.” [7] As such, it does not contribute to calories or carbohydrate, making Timed-Release Protein zero net carbs. Each serving of Timed Release Protein provides 2gm soluble dietary fiber.
