Creatine and HMB: The Stimulant-Free Stack for Strength and Recovery

• Creatine monohydrate replenishes phosphocreatine (PCr) — the fuel your muscles burn hardest in high-intensity effort — enabling faster ATP regeneration.
• According to the ISSN's 2017 Position Stand, creatine monohydrate is identified as "the most effective ergogenic nutritional supplement currently available to athletes" for increasing high-intensity exercise capacity and lean body mass.
• Standard studied maintenance dose: 3–5 g/day. An optional loading phase (~20 g/day for 5–7 days) speeds saturation.
• A 2025 systematic review and meta-analysis found creatine does not adversely affect glomerular filtration rate (GFR) in the populations studied — the actual measure of kidney function.
• HMB (beta-hydroxy beta-methylbutyrate) may reduce muscle protein breakdown via the ubiquitin-proteasome pathway and may support synthesis via mTOR, based primarily on preclinical and in vitro evidence with some clinical support.
• Studied HMB dosing: 1.5–3 g/day. Research suggests that the combination with creatine may produce additive gains in lean body mass under certain conditions.
• Farmana's Workout + Energize provides HMB at 1.5 g (within studied range) and creatine at 900 mg per serving (below the 3–5 g studied maintenance dose — see note below).

Creatine supplementation increases intramuscular creatine and PCr stores, expanding your capacity for rapid ATP regeneration — which research suggests may translate to more force output before fatigue sets in. 

What the ISSN Concluded

The 2017 ISSN Position Stand on creatine (Kreider et al., Journal of the International Society of Sports Nutrition) is the field's authoritative consensus document:

• The ISSN identifies creatine monohydrate as "the most effective ergogenic nutritional supplement currently available to athletes" for increasing high-intensity exercise capacity and lean body mass. 

• According to the ISSN position stand, short- and long-term use (up to 30 g/day for 5 years) has been found safe and well-tolerated in healthy individuals across the reviewed studies. 

• The ISSN position stand reports that high-intensity exercise performance typically improved 10–20% after creatine loading in the studies reviewed, depending on the magnitude of PCr increase. 

Dosing and Loading

Is Creatine Safe for Your Kidneys?

A 2025 systematic review and meta-analysis in BMC Nephrology — 21 studies, literature through March 2025 — found that creatine produces a small, transient rise in serum creatinine but no significant change in glomerular filtration rate (GFR), the primary measure of kidney function, across the populations studied. The rise in creatinine is a predictable metabolic byproduct, not organ damage. A 2024 Mendelian randomization study similarly found no causal association between creatine levels and six indicators of renal function. Those with pre-existing kidney conditions should consult a healthcare provider before use. 

HMB is a metabolite of leucine. At supplemental doses, research suggests it may act through two mechanisms: suppressing the ubiquitin-proteasome pathway (the cellular machinery that breaks down muscle protein under stress) and activating mTOR to support muscle protein synthesis. Per the ISSN's 2024/2025 HMB Position Stand, evidence for ubiquitin-proteasome suppression comes primarily from preclinical studies, while mTORC1 activation has been demonstrated in both in vitro and clinical settings. The ISSN notes that HMB's mTORC1 activation appears independent of the standard leucine-sensing pathway — suggesting a distinct anabolic signal. 

What the Research Shows

An umbrella meta-analysis in the Journal of Cachexia, Sarcopenia and Muscle (2025) — 11 meta-analyses, 41 datasets — found HMB was associated with significantly increased muscle mass (ES: 0.21), fat-free mass (ES: 0.22), and strength index (ES: 0.27), with effects growing stronger at longer durations (8+ weeks). A 2025 meta-analysis in Frontiers in Nutrition recommended 3 g/day for 12+ weeks as the optimal studied protocol, noting 3 g produced greater effects than lower doses in the studies examined.

Dose transparency note: Farmana's Workout + Energize provides 1.5 g of Calcium HMB per serving — the lower bound of the 1.5–3 g studied range. Several studies used 1.5 g twice daily (3 g total) as their protocol.

Creatine and HMB address different bottlenecks in the muscle equation:

A 2001 RCT by Jowko et al. found that combining creatine and HMB produced additive increases in lean body mass and strength — greater than either supplement alone in a 3-week, double-blind, randomized trial — consistent with distinct, non-overlapping mechanisms. A 2019 systematic review in Nutrients found that 3–10 g/day CrM plus 3 g/day HMB may produce potential positive effects on strength and anaerobic performance, and noted possible improvements in body composition, though the authors caution that results were mixed across the small number of studies and further research is needed. A 2025 RCT in active older adults found that creatine + HMB co-supplementation, combined with exercise training, significantly improved multiple functional strength measures over 6 weeks.
