Understanding HMB and How to Evaluate a Brand
Beta-hydroxy-beta-methylbutyrate (HMB) is an active metabolite of the amino acid leucine. It has both anabolic (muscle-building) and anti-catabolic (anti-muscle breakdown) properties, helping to stabilize muscle cell membranes and stimulate protein synthesis. While HMB is naturally produced by the body, supplementation is often used to maximize these effects, especially for those engaged in intense exercise, dieting, or dealing with age-related muscle loss.
When evaluating which brand is best for HMB, it is vital to consider several key factors:
- Ingredient Quality and Purity: Reputable brands will use high-quality, pure HMB and provide evidence of third-party testing. Look for certifications from organizations like USP, NSF, or Informed Choice, which verify that the product's contents match the label and are free from contaminants. Some brands use patented forms, such as myHMB, which indicates a higher quality ingredient.
- Optimal Dosage: Research suggests a daily dosage of around 3 grams is effective for most individuals to see benefits in strength and muscle mass. A good brand will offer a product that allows for this clinically relevant dosage without requiring an excessive number of capsules or servings.
- Form of HMB: HMB is commonly available in two forms: calcium salt (HMB-Ca) and free acid (HMB-FA). While both have their merits, some research suggests HMB-FA is absorbed more quickly and retained in plasma for longer. On the other hand, HMB-Ca is known for its superior bioavailability and faster absorption according to other reviews. The best form depends on your specific goals and timing of intake.
- Additional Ingredients: Some HMB supplements are combined with other beneficial ingredients like Vitamin D3 or creatine, which can enhance overall effectiveness. For instance, vitamin D3 can help with muscle function and overall well-being, while creatine is renowned for boosting strength and power.
Top HMB Supplement Brands Compared
To determine what brand is best for HMB, here is a comparison of some of the leading options on the market, each with unique selling points.
Life Extension Wellness Code Muscle Strength & Restore Formula
Often cited as a top contender, Life Extension offers a comprehensive formula. It provides a full clinical dose of 3 grams of HMB per serving and includes added Vitamin D3 and calcium. A key differentiator is the brand's emphasis on quality and safety, with extensive third-party testing of both raw materials and finished products, as well as NSF and USP verification. The product is in powdered form and generally well-regarded for its overall effectiveness and transparent quality control.
Transparent Labs Creatine HMB
For those who prefer a combination product, Transparent Labs offers a Creatine HMB supplement. This product provides 1.5 grams of HMB along with a full 5 grams of creatine monohydrate per serving. It is an excellent choice for individuals focused on maximizing muscle growth and recovery, as creatine is a well-researched compound for boosting strength.

Nutricost HMB
Nutricost offers a budget-friendly option, with its HMB available in both capsule and powder form. A serving of their HMB with Vitamin D3 provides 1000mg of HMB, which may require multiple servings to reach the clinically studied 3-gram dose. The brand boasts GMP compliance and manufacturing in an FDA-registered facility, making it a reliable, high-quality option for those on a tighter budget.
Bulk Supplements HMB Powder
