Which HMB supplement is best? 

Building muscle involves a consistent workout routine and proper nutrition, but it can be challenging and take time. Many people use protein shakes and other dietary supplements to help them build muscle more quickly.

Hydroxymethylbutyrate is a chemical produced naturally in your body that has gained popularity as a dietary supplement due to its ability to help build muscle. Supplements such as the Tony Horton PowerLife High Impact Plant Protein Powder With HMB let you consume protein and HMB simultaneously.

What to know before you buy an HMB supplement

What HMB is

HMB is produced when your body breaks down leucine, one of the building blocks of protein. According to the National Institutes of Health, it improves protein metabolism in those with muscular dystrophy. HMB also helps with strength, power, muscle damage, mass and delayed onset muscle soreness in athletes. That’s why it’s a popular supplement for building muscle and preventing muscle loss.

How you take an HMB supplement

Many HMB supplements come in capsules. If you have trouble swallowing pills, it’s essential to consider the size of the capsule when choosing an HMB supplement. HMB also can be purchased in powder form and consumed with your protein shake or smoothie. In some cases, you can buy supplements that contain protein and HMB.

HMB vs. creatine

Athletes use both HMB and creatine, and many use them together. But there are minor differences in their effects. HMB is used to prevent muscle breakdown and support muscle recovery. Creatine is primarily used to boost muscle growth. 

What to look for in a quality HMB supplement


Many powdered HMB supplements come in vanilla or chocolate. In some cases, they taste chalky even after being blended into a shake. Still, in many cases the flavor is comparable to that of traditional protein powder.

Effectiveness and safety

These supplements can be relatively pricey, so before buying, read the reviews and ensure people noticed improvements after using the one you’re considering for several weeks . HMB isn’t known to have serious side effects, but it’s also good to ensure people didn’t feel bad after taking a particular supplement.

Additional ingredients

HMB is more effective when taken with vitamin D3 or creatine. Many supplements contain both HMB and one of these, so you won’t have to take as many supplements each day. If you plan to use HMB after working out, consider buying a supplement that contains protein to boost muscle recovery.

Also, check the bottle to ensure that other ingredients won’t cause you problems, either ethically or physically. Some contain gelatin or HMB derived from animals, and not all are gluten-free.

How much you can expect to spend on HMB supplements

You can expect to spend anywhere from $22-$40 on a 3-month supply of capsules. HMB powder with protein costs $50-$60 for a 2-week supply.
