The Active Ingredient Is: Calcium HMB (β-Hydroxy β-Methylbutyrate)

Calcium HMB is a calcium-bound variant of the muscle-supporting metabolite HMB, designed to help keep muscle structure intact during tough training sessions. This mix pairs HMB with calcium to help support skeletal muscle health.

This formula also includes Epicatechin and AstraGin, which help support absorption and the potential muscle benefits from the main ingredient.

What Does Calcium HMB Do?

Calcium HMB helps maintain muscle integrity by supporting normal protein balance during tough exercise, contributing to lean mass maintenance. Dr. Nissen from the university found that HMB supplementation can influence muscle preservation in resistance-trained folks.

The combo of Calcium HMB with Epicatechin and AstraGin works to support nutrient delivery and overall muscle health during training.
