Yamamoto® Nutrition Iso-FUJI 100% NATURAL Volactive® is a dietary supplement featuring whey proteins isolated through cross-flow ultrafiltration and microfiltration, designed for athletes engaging in rigorous physical activities. These proteins play a pivotal role in fostering the growth and maintenance of muscle mass.

Individual protein requirements vary, influenced by factors such as the type and intensity of physical activity and biochemical individuality. According to the latest scientific literature (“NSCA’s Guide to Sport and Exercise Nutrition,” 2011, Campbell & Spano, Human Kinetics), the following values serve as a guide for determining protein requirements based on the type of sport practiced:

• SEDENTARY individuals: 0.7 – 0.9 g/kg body weight/day
• Sportsman with an ACTIVE lifestyle: 1 g/kg body weight/day
• BODYBUILDING athlete: 1.4 – 2.4 g/kg body weight/day (Note: during mass periods, recommended protein intake is 20-30% of total kcal intake from the diet)
• STRENGTH sports: 1.8 – 2 g/kg body weight/day
• COMBAT sports: 1.6 g/kg body weight/day
• TEAM SPORTS (acyclic): 1.6 g/kg body weight/day

Yamamoto® Nutrition Iso-FUJI 100% NATURAL stands out for its composition, featuring 100% Whey Protein Isolate obtained through cross-flow ultrafiltration and microfiltration, ensuring the exclusion of palm oil, maltodextrin, xanthan gum, carrageenan, erythritol, xylitol, and free form amino acids. The use of microfiltration, while a more expensive process, is essential for preserving the integrity and bio-active protein fractions that determine the protein’s quality.

The whey proteins included possess a high biological value and naturally contain branched-chain amino acids (BCAA). The isolated whey protein (WPI) represents the purest form of whey, with Yamamoto® Nutrition Iso-FUJI 100% NATURAL containing whey protein isolated through cross-flow ultrafiltration and microfiltration.

Protein fractions (% of protein)

Beta-Lactoglobulin 50 – 60
Glycomacropeptide15 – 20
Alpha-Lactalbumin 15 – 20
Bovine serum Albumin 1,0 – 2,0
Immunoglobulin G 1,0 – 2,0
Immunoglobulin A 0.1 – 1.0
Lactoferrin 0,1 – 0,5

Microfiltration is the most expensive process of those used for the isolation of protein supplements based on whey proteins, but it is also the one that is best at preserving the integrity and the presence of bio-active protein fractions, which determine the quality of the protein.

The whey obtained in the first stage of processing by ultrafiltration is carried by an apparatus that, using a membrane filter system, proceeds with further progressive filtration, through which other unwanted particles are eliminated, including minerals, lipids and lactose.

The microfiltered proteins are 99% undenatured and retain all the important bio-active peptide fractions of undenatured whey.

Iso-FUJI 100% NATURAL contains whey proteins isolated by cross-flow ultrafiltration and microfiltration, it does NOT contain collagen with other elements that alter the quality or the biological value of the product.

What does Volactive® UltraWhey XP certification and raw material mean?

Volac® is a reference reality in the dairy and livestock production sector, as well as the largest producer of
Nutritional Whey Protein for Lifestyle Applications in Europe, which has earned an absolute reputation
innovative company in production technology and development in the nutritional field.

Volac’s technical-scientific team draws on the company’s forty-year heritage in the processing of whey and the use of cutting-edge ultrafiltration techniques. The Volactive® product range is born from the use of the most recent complex drying technologies membrane and spray that effectively stabilizes the protein matter, reducing the denaturation of the protein to an absolute minimum, thus providing the obtainment of whey proteins with highly superior nutritional profiles compared to other protein preparations obtained with other processing methods that compromise stability.

“Volac® officially certifies and guarantees the content of Yamamoto® Nutrition proteins.”
