Shilajit for Athletic Performance and Recovery

In short: One small, eight-week study of a specific Shilajit extract reported a subgroup finding on strength decline after a laboratory fatigue protocol. It does not show that Shilajit Gold+ improves sport performance, everyday stamina or muscle recovery.

What the exercise study tested

Keller and colleagues randomly assigned 63 recreationally active men (21 per group) to 250 mg per day of PrimaVie Shilajit, 500 mg per day, or placebo for eight weeks. The researchers measured maximal voluntary isometric contraction (MVIC), concentric leg-extension torque, fatigue-related change in strength and serum hydroxyproline.

The reported strength finding was in a subgroup whose baseline MVIC was above the study median: after supplementation, the 500 mg group had a smaller percentage decline in MVIC following the laboratory fatigue protocol than the 250 mg and placebo groups. This was a subgroup result on a specific test. It is not evidence that participants performed better in sport or recovered faster between training sessions.

The study tested a standardised extract and dose. Those are not equivalent to the different multi-ingredient Gold+ Capsules or Resin formulas. The study does not establish an effect for either product.

What the study does not establish

• Improved competition results, endurance or general stamina.
• Less delayed-onset muscle soreness, faster tissue repair or a shorter recovery period.
• Prevention or treatment of injury.
• The same result for women, other populations, other Shilajit products or longer-term use.

The trial was small, lasted eight weeks and included recreationally active men. The strength result described above came from a baseline subgroup analysis. Read the full Keller et al. study for its methods, results and limitations.

The founder’s confirmed routine

I have used Shilajit for around two years, usually taking Resin in the morning and using Capsules when I do not get the chance to take Resin. I have not tried powder. This account is separate from the exercise study above; it is not evidence of an athletic-performance or recovery effect.

Ayurveda discusses Shilajit within Rasayana, a traditional framework concerned with vitality and wellbeing over time. That context is part of the ingredient’s history, but it does not establish an athletic-performance or recovery effect in modern sport.

If you are considering Gold+ as part of a general routine, compare the complete Capsules and Resin formulas and follow the directions for the exact format. Convenience may help you choose a routine that suits you; it does not make either format equivalent to the extract tested in the study above.

Sport and supplement testing

A laboratory report for a submitted product sample is not an anti-doping certification and cannot guarantee that a supplement is free of prohibited substances. UK Anti-Doping’s supplement guidance explains that athletes are responsible for substances found in their system and that no supplement can be guaranteed free from prohibited substances. Athletes should assess the need and risk with a suitably qualified sports professional and follow the rules of their sport.
