HMB Supplements for Women: 8 Brands Compared (2026)

AgelessLX, BulkSupplements, Double Wood, Legion, NOW Sports, Nutricost, Optimum Nutrition, and Transparent Labs offer HMB-containing supplements worth comparing by label. The practical choice depends on the format you prefer, the other ingredients you already use, and the product’s directions.

This guide explains the differences between selected products. “Best” is personal to the buyer’s needs; the list does not rank clinical effectiveness or establish that a product is suitable for every woman.

How to Compare HMB Supplement Labels

Start with serving size, then the amount and form of HMB, followed by other ingredients and daily directions. FDA’s supplement guidance explains the information manufacturers must put on the label.

Check	What to compare
Serving size	One scoop, packet, or group of capsules may count as one serving.
HMB entry	Read the HMB line and ingredient form. Total powder weight, calcium HMB compound weight, and an HMB-specific entry are not automatically equivalent.
Other ingredients	Check vitamins, botanicals, creatine, sweeteners, and capsule materials against your preferences and existing supplements.
Daily directions	A labeled serving and a full day’s intake may be different. Use the manufacturer’s directions.

Powder or capsules?

A powder needs measuring or mixing; capsules need no mixing but may require several capsules per day. Choose a format you can use as directed. Neither format, by itself, demonstrates better results.

HMB-focused formula or combination product?

Compare the complete ingredient panels. A creatine-and-HMB powder is a different purchase from HMB capsules with vitamin D3. Avoid doubling up on ingredients simply because the products have different names.

How should you compare cost?

Compare the same purchase type, package size, and daily directions. Cost per day equals the package price divided by the number of days it lasts at those directions. Include delivery charges and check subscription renewal terms.

What Distinguishes Each Brand?

AgelessLX: flavored powder and capsule options [Sponsored]

AgelessLX offers a Strawberry Lemonade drink powder and a capsule format. The powder label lists 3,000 mg HMB per 5.7 g stick pack; the capsule label lists 1,500 mg per three capsules. Both also list vitamin D, vitamin K, biotin, calcium, and horsetail extract. The product directions specify one packet in 16 fl oz of water daily, or three capsules twice daily, respectively.

For the wider choice of flavors, see the AgelessLX product collection. Select a product first, then review its own label rather than assuming every flavor or format is identical.

BulkSupplements: powder and capsule listings

BulkSupplements lists HMB powder and capsules in multiple package options. The 250 g powder label lists 825 mg HMB and 155 mg calcium per approximately 1 g serving. The 300-capsule label lists the same amounts per two capsules; the 360-capsule label lists 2,550 mg HMB and 450 mg calcium per six capsules. The capsule shells contain bovine gelatin. Use the Supplement Facts HMB entry, not the larger 1,000 mg or 3,000 mg variant name, when comparing HMB amounts.

Double Wood: capsules with testing information

Double Wood’s HMB capsule page specifies two 500 mg capsules daily and links to a certificate of analysis and third-party test results. Match any report’s lot number to the bottle you buy; a report covers the tested lot and is not evidence of a particular health result. The page showed the product as backordered at review.

Legion: HMB combined with creatine

Legion’s Creatine + HMB is an unflavored powder. Its product page lists 5 g micronized creatine monohydrate and 2.5 g myHMB per serving, with directions to mix one scoop into 10–12 fl oz of a beverage and use one serving daily. Check both ingredients if you already take creatine.

NOW Sports: HMB capsules with vitamin D3

The NOW Sports HMB 500 mg Vegetarian Capsules label lists 1,000 mg HMB, 12.5 mcg vitamin D3, and 160 mg calcium per two-capsule serving. The official directions specify two capsules two to three times daily with food. A serving is therefore not the full daily intake. Include its vitamin D and calcium when checking overlap with other supplements.

Nutricost: a choice of delivery formats

Nutricost has separate HMB powder and capsule listings. The 250 g powder page lists 1,000 mg HMB per serving and 250 servings. The capsule page lists 500 mg per capsule and 1,000 mg per serving, equivalent to two capsules. Capsule-count options include 60, 120, and 240; select the package before calculating supply.

Optimum Nutrition: an HMB capsule option

Optimum Nutrition’s HMB Caps Supplement Facts label lists 3 g calcium HMB monohydrate and 380 mg calcium per three-capsule serving, with 30 servings in the 90-capsule bottle. The product directions specify three capsules daily. The 3 g entry is per serving, not per capsule; this comparison follows the label rather than the conflicting per-capsule wording in the page overview. Other ingredients include gelatin.

Transparent Labs: a broader combination powder

Transparent Labs Creatine HMB is a combination powder. The linked Peach Mango 60-serving label lists a 9.4 g scoop containing 5,000 mg creatine monohydrate, 1,500 mg HMB, 12.5 mcg vitamin D3, 200 mg calcium, and 5 mg BioPerine black pepper extract. Check the exact flavor and package label, and account for any other creatine or vitamin D supplements.

Precautions Before Choosing a Formula

Review your medicines, other supplements, and the full label with a healthcare professional before use. FDA notes that supplements can interact with medicines or other supplements.

Biotin can interfere with certain laboratory tests. Tell your healthcare professional and laboratory staff about biotin-containing products before testing. NIH’s biotin fact sheet explains this issue.

Vitamin K can interact with warfarin. Discuss changes in vitamin K-containing products with your prescriber; see NIH’s vitamin K guidance.

Frequently Asked Questions

Is there one best HMB supplement for every woman?

No single label comparison establishes a universal best choice. Narrow the list by format, companion ingredients, directions, and personal health considerations, then compare the specific products.

Does a higher HMB number mean a better product?

A larger printed number may reflect a larger serving or a different way of stating the ingredient form. Compare like-for-like label entries. Amount alone does not show what results a supplement will produce.

Can a study of HMB establish the results of every HMB product?

A study must be read in the context of the formula, dose, participants, and outcomes tested. Ingredient research alone does not establish the results of a different finished formula.

Where can I check the AgelessLX formula and directions?

[Sponsored] Use the official powder and capsule product pages for the selected format. For a practical explanation of serving sizes, added nutrients, and precautions, see our supplement label guide.

A Practical Buying Checklist

Choose your preferred format, read the complete label, compare any overlapping ingredients, and calculate cost using the daily directions. Check any testing document against the product and lot it covers. Keep the label available for a conversation with your healthcare professional.
