Optipep 90 PRO

Hydrolysed whey protein isolate that delivers a high-quality source of peptides

The high-quality protein

Optipep 90 PRO is a hydrolysed whey protein isolate that delivers a high-quality source of peptides. It is lightly hydrolysed, offering a low bitter flavour profile, suitable for use in enhanced nutritional and functional formulations. Instantised version available.

Whey protein hydrolysates deliver all the benefits of whey protein but are more rapidly absorbed and easily digested, which means increased amino acid availability to support the growth and maintenance of muscle mass.


Whey protein has also shown positive nutritional benefits for those with specific needs, such as protein malnutrition, critical care, GI disorders, sarcopenia and glycaemic management.

Hydrolysed for Faster Absorption

Optipep 90 PRO contains specialised pre-digested whey protein fractions called di & tripeptides. These smaller fractions are an efficient form for protein transport and are more rapidly absorbed to support enhanced muscle growth and recovery following intense exercise.

Whey Protein Hydrolystate increases muscle protein synthesis

WPH has been shown to have the fastest absorption rates compared to other protein sources (Figure 1 Carbery metaanalysis 2019) with peak total AAs occurring at +/- 30 mins post-ingestion.

WPH has been shown to result in a higher rate of Muscle Protein Synthesis (MPS) post exercise relative to other protein sources (Figure 2 Tang et al. Journal Applied Physiology 2009). This is due to superior digestion and absorption kinetics and higher protein quality with a greater proportion of EAA, and in particular leucine. Leucine is a key stimulator of MPS (Atherton et al. Amino Acids 2010).


Features & Benefits

  1. Superior source of protein & excellent biological value (PDCASS/DIAAS >1). Rich source of essential amino acids (EAA) & naturally high in branched chain amino acids (BCAAs); leucine, isoleucine and valine.
  2. Reduced allergenic potential compared to intact proteins.
  3. Faster absorption & easier digestion compared to intact protein and free amino acids.
  4. Optimised peptide profile for enhanced bioactivity.
  5. Stimulation of muscle protein synthesis to help prevent muscle disuse atrophy.
