4LIVN HMB Fruit Chews deliver 3g of USP Verified myHMB per serving, the full clinically studied dose, in a vegan chewable at $29.99 for 90 count.
Overview
LIVN Nutrition launched HMB Fruit Chews as, by its account, the first chewable HMB format. The product provides 3g of myHMB per serving in a sour orange flavour, sold at $29.99 for a 90-count pouch. The chews are vegan and pectin-based rather than gelatin-based.
The dose is what makes this worth attention. HMB, beta-hydroxy-beta-methylbutyrate, is a metabolite of the amino acid leucine, and the research on it for reducing muscle protein breakdown generally uses 3g a day. Most products that list HMB on their labels provide considerably less. BariMelts, one of the better competitors, includes 1,500mg. 4LIVN provides the full 3g, which means the comparison with the published literature is a fair one.
The ingredient is myHMB, a branded form from TSI Group that appears in most of the published HMB research and is used by the Vitamin Shoppe in its own GLP-1 protein. It is USP Verified here, which is a stricter third-party standard than the generic testing claims common in this category. TSI has published material specifically on HMB in obesity care and muscle preservation during GLP-1 therapy, which is the relevant use case: rapid weight loss costs lean mass as well as fat, and that is the most serious risk this population faces.

Supplement or Medication?
A dietary supplement. HMB is a naturally occurring metabolite of leucine studied for reducing muscle protein breakdown. It has no effect on GLP-1, appetite or weight directly; its purpose is protecting lean mass while you lose weight by other means.
How You Buy It
Buy direct
Sold through 4LIVN's own site at $29.99 for 90 chews.
Take the full serving
The 3g dose is the point; taking less loses the benefit.
Combine with resistance training
HMB works considerably better alongside strength work.
Get your protein elsewhere
This addresses muscle breakdown, not total protein intake.
Who It Is Sold To
- Adults losing weight rapidly and concerned about muscle loss
- No consultation or clinical assessment involved
- Suitable for vegans, as the chews are pectin-based
- Most useful when combined with resistance training
- Not appropriate as a substitute for prescribed obesity treatment
- Review the full ingredient panel if you have sensitivities
Clinical Oversight and Evidence
Clinical Oversight
None. This is a retail supplement with no clinical involvement. If muscle loss is a serious concern, a conversation about resistance training and total protein intake will do more than any single supplement.
Evidence
Good at the ingredient level. HMB has a substantial published literature for reducing muscle protein breakdown, generally at 3g a day, and myHMB is the branded form used in much of it. Its supplier has published material on HMB in obesity care and muscle preservation during GLP-1 therapy. No trial exists on this specific chewable product.

Frequently Asked Questions
How much HMB is in a serving?
3g of myHMB, which is the dose used in the published research. Most products listing HMB provide considerably less, so this is unusual.
What does USP Verified mean?
It is a third-party verification standard confirming that the product contains what the label says, in the stated amount, and was made to good manufacturing practices. It is stricter than the generic third-party testing claims common in this category.
Does HMB actually preserve muscle?
It has a substantial published literature for reducing muscle protein breakdown during weight loss, which is the most serious risk on GLP-1 medication. It works considerably better alongside resistance training.
Is it vegan?
Yes. The chews are pectin-based rather than gelatin-based, with no animal-derived ingredients.
Do I still need protein?
Yes. HMB reduces muscle breakdown but does not supply the amino acids for building muscle. You need adequate dietary or supplemental protein alongside it.
How much does it cost?
$29.99 for 90 chews, which is 30 servings at the full 3g dose, or around $1 a serving.
Is it FDA approved?
No. It is a dietary supplement, so it does not require FDA approval before marketing and its claims have not been evaluated by the FDA.
