Supplements for Recovery: What's Worth Taking

Recovery supplements are a large category with enormous variation in evidence quality. Some genuinely accelerate recovery; many are expensive placebos. This guide covers what the research actually supports.

Why Recovery Supplements Matter More on a Cut

Recovery is slower during a calorie deficit. Reduced calorie availability means less energy for tissue repair, lower anabolic hormone levels, and potentially suboptimal micronutrient intake if food choices are restricted. Supporting recovery becomes more important, not less, when you're cutting.

Tier 1: Well-Evidenced Recovery Supplements

Creatine Monohydrate

Already covered in detail in the creatine guide, but worth noting here: creatine supports faster phosphocreatine resynthesis between sets and has evidence for reducing DOMS duration. 3–5g daily.

Protein (Whey or Casein)

Post-workout protein supports muscle protein synthesis during the recovery window. A whey protein shake within 1–2 hours of training reliably supports this. Casein before bed extends the recovery window overnight.

Vitamin D3

Low vitamin D is associated with impaired muscle function, reduced testosterone, and slower recovery times. Given UK latitude and lifestyle, supplementation is justified for most people year-round. 2,000–4,000 IU daily.

Omega-3 (EPA/DHA)

Anti-inflammatory. Reduces DOMS in multiple studies. May support muscle protein synthesis in a deficit. 2–3g combined EPA+DHA daily.

Magnesium Glycinate

Supports muscle relaxation, reduces cramping, and critically — improves sleep quality, which is the most powerful recovery tool available. 300–400mg before bed.

Tier 2: Useful with Caveats

Tart Cherry Juice / Extract

One of the more interesting recovery supplements. Multiple studies show tart cherry (particularly the Montmorency variety) reduces DOMS, muscle damage markers, and oxidative stress after intense exercise. This is attributed to the high anthocyanin content.

The caveat: the effect size is modest (not dramatic); the juice form is high in sugar (a concern during a strict cut); extract capsules are the better form for cutting phases.

Dose: 480mg tart cherry extract twice daily, or 30ml concentrated juice twice daily (but log the calories).

Collagen + Vitamin C

There's growing evidence that collagen peptides (10–15g) combined with vitamin C, taken 30–60 minutes before a training session, supports connective tissue health — tendons, ligaments, cartilage. This is relevant if you're experiencing joint discomfort, which is more common when cutting (due to reduced lubrication from lower dietary fat).

Zinc

Zinc supports testosterone, immune function, and protein synthesis. Commonly deficient in people eating a restricted diet or low in red meat and shellfish. 15–25mg zinc bisglycinate or zinc picolinate daily.

Tier 3: Minimal Evidence

Glutamine

Heavily marketed for muscle recovery and immune support. Evidence in well-nourished individuals is weak — glutamine can be synthesised endogenously in adequate amounts if protein intake is sufficient.

HMB (Beta-Hydroxy Beta-Methylbutyrate)

Some evidence in older or untrained populations. Minimal benefit in trained individuals at normal doses.

BCAA post-workout

As discussed in the BCAA guide — redundant if total protein intake is adequate. Whole protein sources provide a superior amino acid stimulus for recovery.

Key Takeaways

• Recovery supplements matter more on a cut because calorie restriction slows natural recovery
• The best-evidenced recovery supplements: creatine, vitamin D, omega-3, magnesium
• Tart cherry extract has interesting evidence for DOMS reduction
• Collagen + vitamin C pre-workout supports connective tissue health — useful if joints are under stress
• Sleep, protein, and appropriate training volume are the foundations that supplements build on
