Recovery Pt. 7 — Supplements (2/3)

Here, we consider systemic and structural interventions that operate over longer timeframes to address broader recovery.

Creatine has the strongest, consistent evidence of any supplement in this space. Its primary mechanism is to accelerate phosphocreatine resynthesis, which trims the time needed to restore ATP between efforts.

Benefits extend beyond energy replenishment, with evidence implying it attenuates both the damage markers and the soreness that follow in the days after a hard session. Critically, it does not blunt the inflammatory or adaptive response the way NSAIDs do.

This distinction matters. A supplement that suppresses recovery-relevant inflammation to reduce soreness is making a trade most shouldn't want to make. Creatine's recovery profile is favorable precisely because it operates on the energy and structural side without interfering with the adaptive cascade.

There is emerging evidence for cognitive and neurological recovery, with reduced mental fatigue under sleep deprivation, and reduced concussive biomarkers in contact sport athletes.

For deficiencies that directly impair recovery, two choices stand above the rest:

Magnesium is involved in over 300 enzymatic processes, including muscle contraction and relaxation, protein synthesis, and sleep architecture. Deficiency is common, with the gap between intake and need being wider than most assume.

Formulation matters. Magnesium threonate and glycinate are the relevant choices; both cross the blood-brain barrier more effectively than oxide formulations, which are poorly absorbed and primarily function as laxatives. If sleep is compromised and nothing else obvious explains it, magnesium is one of the first things worth examining.

Vitamin D is more a corrective for widespread deficiency than a performance supplement. Its role in muscle protein synthesis, immune function, and hormonal regulation is well-established. Most are operating below optimal levels without knowing it, particularly those training indoors or at higher latitudes. Bloodwork is the only reliable way to assess status; what corrects deficiency in one person may be insufficient in another.
