Deer velvet antler,
does it really help with Improved physical performance and exercise recovery?
research showsRandomized exercise trials generally failed to replicate performance benefits, and isolated strength signals were not robust because of multiple comparisons, formulation inconsistency, and attrition. Exercise recovery also lacks consistent benefit, resulting in an F grade.
ads claimAdvertisements combine claims of tonification, IGF-1, strength, endurance, and recovery, while controlled trials do not consistently support this bundle.
Useful facts when choosing a product
- Studies used different formulations, including powder, extract, and fermented extract.
- Main outcomes included maximum oxygen uptake, strength, endurance, hormones, and muscle-damage markers.
- Species, antler section, and processing of marketed products may differ from study products.
What the research actually shows
Sleivert 2003 randomized 38 active men and found no change in maximum oxygen uptake, hormones, or red-cell measures, with only selected strength outcomes positive in the powder group. Gilbey 2012 found that five of seven RCTs were null and judged positive sports findings unconvincing. Earnest 2015 randomized 32 participants, but only 18 completed the trial; selected positive signals were limited by high attrition and analytical concerns.
Why this is classified as F (15)
Core exercise-performance outcomes were repeatedly null across randomized trials, while isolated positive findings lack robust replication and analysis, resulting in F with 15 points.
Counterpoint. A selected strength signal in a powder formulation remains but does not change the overall repeated null evidence.
Rejudgment record. Reassessment (cross-check reflected) — Repeated null core outcomes in several sports-performance RCTs; isolated positives limited by formulation inconsistency, attrition, and analysis
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Improved physical and exercise performance | F | Several RCTs found no consistent benefit for maximum oxygen uptake, strength, or hormones |
| Improved exercise recovery | F | Controlled benefits for muscle-damage and recovery measures were not replicated |

Evidence Table
| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Sleivert G et al. 2003 | Randomized double-blind three-arm placebo-controlled trial | 38 | Possible New Zealand velvet-industry support; details unknown | Maximum oxygen uptake, strength, endurance, hormones, and red-cell mass | No change occurred in maximum oxygen uptake, hormones, or red-cell measures; selected strength and endurance outcomes were positive only in the powder group. | Key |
| Gilbey A et al. 2012 | Systematic review of randomized trials | 3 | Unknown | Sports performance and other clinical efficacy outcomes | Five of seven trials were null, and the two positive findings were judged unconvincing. | Key synthesis |
| Earnest CP et al. 2015 | Randomized double-blind placebo-controlled trial | 18 | Included an industry-affiliated author | Maximum oxygen uptake, one-repetition maximum, anaerobic power, and body composition | Selected within-group and relative-strength signals appeared, but anaerobic performance did not improve and attrition was high. | Supportive, industry-linked |
