Training during Ramadan is one of the most specific performance nutrition questions in UK sport — and one of the least well-answered. Most sports nutrition guides are written for athletes who eat freely throughout the day. Most Ramadan supplement guides are written for general wellness rather than athletic performance. This guide addresses the intersection: what Muslim athletes actually need during Ramadan, what the evidence supports, and which halal approved products address those needs.
The physiology of training during Ramadan
UK Ramadan fasting periods range from approximately 12 hours (winter) to 18+ hours (summer). For athletes, the physiological changes during this window include:
- Glycogen depletion: liver and muscle glycogen stores decline significantly through the fasting day, particularly in training athletes. By late afternoon (the period many athletes train), glycogen availability is substantially reduced.
- Dehydration and electrolyte loss: sweat losses are not replaced during the fasting window. A 2019 study in the Journal of the International Society of Sports Nutrition found significant dehydration and electrolyte depletion in Ramadan-fasting athletes, with effects most pronounced in summer months.
- Muscle protein breakdown: extended fasting increases muscle protein catabolism, particularly pronounced during and after training sessions timed in the fasting window. Net muscle protein balance is harder to maintain without post-training protein.
- Sleep disruption: Tarawih prayers, altered meal timing and earlier Suhoor disrupt sleep architecture. Sleep is the primary recovery window for muscle repair, hormone regulation and cognitive restoration.
When to train
In short: train when food and fluid are close at hand, either shortly before Iftar (light sessions) or after Iftar once you've eaten and rehydrated (strength and higher-intensity work). The middle of the fasting day is the worst window, because glycogen is lowest, dehydration is greatest and recovery is furthest away. For the three training windows compared, a sample week, and hydration and sleep planning, see our Ramadan training schedule.
Supplements: what to take at Suhoor vs Iftar
Anything swallowed during fasting hours, including capsules, powders and drinks, breaks the fast, so every supplement below belongs at Suhoor or Iftar. For the format-by-format detail, see Does taking a supplement break your fast?
| Supplement | Timing | Why | BioBodyBoost product |
|---|---|---|---|
| Creatine monohydrate (3–5g) | Either window — timing irrelevant | Chronic muscle saturation; daily consistency is what matters, not meal proximity | Creatine Monohydrate |
| Electrolytes (immediately) | First thing at Iftar | Replaces sodium, potassium, chloride before food; reduces headache and cognitive fog | Electro-Hidr8 |
| Protein (30–40g) | Post-training / at Iftar | Muscle protein synthesis requires leucine threshold (~2g leucine per serving); 30g quality protein covers this | PeaPro Pea Protein (halal approved, vegan) |
| Magnesium glycinate (300mg) | After Tarawih / before sleep | Muscle relaxation, recovery quality, sleep depth; magnesium is depleted through sweat during training | Magnesium 3 Complex |
| Vitamin D3 + K2 | Iftar — with food | Fat-soluble: 56% absorption improvement with fat-containing meal (Mulligan 2010 JBMR) | Lipovita D3+K2 |
| Omega-3 (at least 250mg EPA+DHA) | Suhoor or Iftar — with food | Fat-soluble; absorbs better with food. 250mg EPA+DHA daily is the amount linked to the authorised heart function claim | OmegaBalance (3 capsules = 285mg EPA+DHA) |
| Probiotic | Suhoor — with small meal | Microbiome follows circadian rhythm; Ramadan eating pattern disrupts it; probiotic maintains gut function | BioTic 20 Billion |
Creatine and Ramadan: the specific question Muslim athletes ask
Creatine powder is swallowed, so taking it during fasting hours breaks the fast in the same way as any other drink or supplement. Fortunately, timing doesn't matter for creatine: it works through gradual muscle phosphocreatine saturation, not acute dosing. Taking it once daily at Suhoor or Iftar maintains full effect.
BioBodyBoost Creatine Monohydrate is pure synthetic creatine (no animal sourcing), halal approved, vegan, and mixes easily in water. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise, with the beneficial effect obtained with a daily intake of 3g. Full detail: Is creatine halal?

Protein during Ramadan: meeting targets in two windows
For trained athletes, daily protein requirements of 1.6–2.2g/kg body weight are significantly harder to achieve in two eating windows than throughout the day. A 75kg athlete needs 120–165g protein daily, so meeting this in two meals requires deliberate planning. Protein powder at both Suhoor and Iftar is the most practical supplementation strategy. BioBodyBoost PeaPro provides 20–25g protein per serving: halal approved, no animal ingredients, mixes in water.
What to avoid during Ramadan training
- High-stimulant pre-workouts on an empty stomach: large caffeine doses worsen dehydration, cause blood glucose instability and produce uncomfortable jitteriness. If you want caffeine before a post-Iftar session, keep it moderate.
- BCAAs as a fasting-window "hack": like any supplement, BCAAs break the fast if taken during fasting hours. Take them at Suhoor or Iftar only if your protein intake is low; they're redundant if total protein is adequate.
- Iron supplements at Iftar alongside dairy: calcium blocks iron absorption by up to 49% (Hallberg 1991). Take iron at Suhoor away from dairy if supplementing.

Does creatine break the fast during Ramadan?
Yes, if you take it during fasting hours, because it's swallowed. Take it at Suhoor or Iftar instead. Timing has no effect on how creatine works, so you lose nothing by moving it into the eating windows. For a personal ruling, consult a qualified scholar.
What protein should Muslim athletes take during Ramadan?
Halal approved plant protein (pea, rice) or halal approved whey made with microbial rennet are the appropriate options. Pea protein isolate at 20–30g per serving provides a near-complete amino acid profile, with leucine content close to the ~2g threshold for stimulating muscle protein synthesis. Take protein at Suhoor and Iftar, aiming for around 0.4g/kg body weight per meal.
How do Muslim athletes maintain muscle during Ramadan?
(1) Keep daily protein at 1.6–2.2g/kg from halal sources, split across Suhoor and Iftar; (2) continue creatine monohydrate at 3–5g/day in either eating window; (3) train shortly before Iftar or after Iftar, not in the middle of the fasting day (see our training schedule); (4) take magnesium after Tarawih to support sleep and recovery; (5) take electrolytes at Iftar to begin rehydrating.
