Pro-JYM is a protein powder supplement made by JYM Supplement Nutrition.
It’s a protein-blend formula, designed for lean muscle gain and recovery.
JYM Supplement Science was created by Jim Stoppani, a well-known physiologist and bodybuilder.
Casein is the slow-digesting protein found in cow’s milk.
Research has shown it to significantly boost amino acid levels, and stimulate muscle growth (1).
Although not ideal for post-workout consumption on its own, casein provides a steady stream of protein for muscle repair.
Whey Protein Isolate
Whey is the fast-digesting protein found in cow’s milk.
It’s the most common protein used post-workout, due to its rapid absorption.
Like casein, whey has also been shown to significantly boost muscle growth and repair (2).
Isolate is a very refined form of whey, which contains just small traces of carbohydrates and fats.
Milk Protein Isolate
Milk Protein Isolate is a refined version of milk protein, which includes both casein and whey protein.
Egg protein is yet another source of protein which is great for muscle growth and repair.
It’s included here for its “medium-speed” absorption – digested slower than whey, but faster than casein.
Who Takes It?
Athletes wanting a quality protein blend for lean muscle growth will enjoy using Pro-JYM.
How to Take
Take 1 scoop (39g) with 250mL water before and/or after working out.
Excess protein consumption may worsen an existing liver or kidney condition.
- Contains a range of protein sources, which absorb at different rates
- Variety of flavour options
- Somewhat expensive compared to other protein powders
- No special extras
Pro-JYM is a high-end protein powder that contains a bunch of different protein sources, which provide a long, steady stream of amino acids.
This may be marginally better for results than single-source protein powders – however with no extra special ingredients or features, it may not be worth the price.
Unless you have money to burn, you may get better value for your money from another protein powder.
