RX Muscle Force

Top muscle development and strength

The only product with collagen for your joints and over 35 active components that promote good shape and muscle power


MARNYS SPORTS® RX Muscle FORCE is a formula designed to maximise your post workout with the aim of getting fit muscles.

It contains 44g of carbohydrates, 35g of proteins and hydrolysed collagen that, along with BETAFOR3MAX® unique formula, promote muscle power and capacity.


The synergistic combination of the ingredients in MARNYS SPORTS® RX Muscle FORCE provides the following properties:

  • Carbohydrates from 6 sources: oats and brown rice, spelt, rice, fructose and isomaltulose, which are primary sources of energy to keep our muscle mass fit. These carbohydrates are differentiated by their absorption capacity in fast (rice and spelt) and slow (oats and brown rice, fructose and isomaltulose), which combined achieve optimising carbohydrate oxidation and therefore the energy produced. The carbohydrates in the formulation of MARNYS® SPORTS RX Muscle Force together with minerals contribute to the maintenance of endurance during prolonged exercise (EFSA).
  • The proteins come from soya, peas, egg white and dairy products (casein, caseinate and whey). They provide 35g proteins per serving and contribute to muscle mass growth and normal bone maintenance (EFSA).
  • The formulation of MARNYS® SPORTS RX Muscle Force includes type I hydrolysed collagen, a fibrous protein whose properties control the disposition, assembly, integrity and mechanical properties of bones, cartilage, tendons and joints.
  • RX Muscle Force includes BETAFOR3MAX®, an exclusive formula by MARNYS® with controlled-release β-alanine that minimises the paraesthetic effects of β-alanine when supplied as a shot, since our body gradually, and in a controlled way, releases β-alanine into the bloodstream. β-alanine is a non-essential amino acid involved in muscle contractility, the activity of calcium in muscle fibres and pH balance
  • Creatine improves physical performance in successive sets of short-term, high intensity bouts (EFSA). The reatine monohydrate in RX Muscle Force has been the most widely studied and its formulation has proven to be very helpful in short-term exercise, weight lifting, high intensity exercise and in cycling, among others
  • Potassium contributes to normal function of the nervous system and muscles, as well as to maintenance of blood pressure under normal levels (EFSA).
  • The combination of the essential amino acids L-arginine and BCAA, and the amino acid L-glutamine provide substrate for muscle building, as well as for energy activity.
  • Sodium is an essential nutrient for the normal function of the body as it is involved in nerve conduction, muscle contraction, osmotic balance of the body and uptake of other nutrients.
  • Calcium contributes to normal energy-yielding metabolism and to normal function of digestive enzymes. It also contributes to normal function of muscles and neurotransmission, being necessary for the normal maintenance of bones (EFSA).
  • Chloride contributes to normal digestion for the production of hydrochloric acid in the stomach (EFSA).
  • Multi-enzymatic complex consisting of 5 enzymes: Amylase, Protease, Lactase, Lipase and Cellulase. These enzymes have well-known digestive properties and are naturally found in saliva, gastric juice, pancreatic juice and intestinal secretions.

To maximise gains in muscle mass at the upper physiological limit, it is necessary to incorporate components that can maximise power, restore the glycogen used, and stimulate to the maximum the response that leads the body to initiate all these processes of synthesis. This does not only affect the muscle fibres, but also their energy stores.
