HMB (β-Hydroxy β-methylbutyric acid) is a substance that occurs naturally in humans as a metabolite of the amino acid L-leucine. Supplementing with HMB helps to support muscle mass, protein breakdown in muscles, supports protein stores in aging individuals and assists post exercise recovery.

Did you know muscle mass peaks at 30?

Muscle mass peaks around 30 years of age, and naturally declines on average 1% per year. This accelerates in our 70s on average 15% per decade.

The combination of HMB and vitamin D3 supports muscle mass in ageing individuals by reducing protein breakdown in the muscles.

HMB supports muscle health as you age by maintaining your muscle mass and muscle protein stores.

Vitamin D supports the metabolism of calcium in your bones, so you stay stronger for longer.

So what is HMB?

HMB is produced naturally in the body in small amounts when metabolising the amino acid leucine. HMB may help to reduce muscle protein breakdown as well as stimulate protein synthesis and provide benefits to exercise. In order to maximise HMB’s anticatabolic properties, it is necessary to supplement with around 3g per day in order to raise levels in the body.



  • HMB, or beta-hydroxy-beta-methylbutyrate, is the active metabolite of leucine, a branched chain amino acid.
  • HMB is known to help maintain muscle mass in healthy aging individuals in conjunction with or without exercise.
  • HMB both stimulates protein synthesis and reduces breakdown within the muscles.


  • Vitamin D levels are important for muscle health. Higher serum levels of vitamin D are associated with muscle function, especially in older adults where sun exposure may be inadequate.
  • Vitamin D is an essential nutrient to promote calcium metabolism in bones.

Benefits of HMB

Supplementing with 3g HMB daily may reduce age-related muscle loss and stimulate muscle protein synthesis.

HMB supplementation paired with exercise helps in the maintenance of body composition in older adults. HMB may also help the elderly with a sedentary lifestyle to maintain lean body mass.

Benefits of HMB

Maintain muscle mass

Supplementing with HMB helps to increase whole body protein turnover and contributes to increasing lean body mass in older adults.

HMB may also help the elderly with a sedentary lifestyle to maintain lean body mass.

Reduce protein breakdown

A body of evidence recommends that at least 3g of HMB per day is required in order to obtain the muscle-sparing benefits via reduced protein breakdown in the muscle.

Stay stronger for longer

HMB helps reduce age-related decline in body composition which contributes to maintaining or improving quality of life.

Why does Healthy Muscle Mass Matter?

Maintains routines

Healthy muscle mass can help you move freely to complete daily routines such as walking, gardening, making the bed, cleaning the house or other fun activities.

Boost calcium metabolism in bones

Strong muscles keep the joints in good shape.

Bioglan Muscle Protect HMB + D3

Each film-coated tablet contains 1000mg Calcium Beta-Hydroxy-Beta-Methylbutyrate Monohydrate (HMB) + 8.33 micrograms (333.3 IU) Colecalciferol (Vitamin D3).


  • How much HMB should I take and how regularly can it be taken?

    At least 3g HMB should be supplemented daily in order to experience HMB’s muscle-sparing and protein synthesising benefits.
  • When should I take HMB?

    Individuals aged 40+ should begin considering HMB supplementation. Active individuals may also benefit from taking HMB near exercising or working out. HMB is most effective when consumed for at least two weeks prior to exercise.

  • What are the benefits of HMB with Vitamin D?

    Vitamin D is an essential nutrient for healthy muscle function and contraction.
