If you’re searching for the best RED-S nutrition support in the UK or a dedicated RED-S clinic, you are in the right place.
Are you always exhausted, struggling to recover, or seeing your performance decline despite training hard?
You could be suffering from Relative Energy Deficiency in Sport (RED-S) - a common yet often overlooked condition that affects athletes of all levels.
At Nutrition and Co., we specialize in helping athletes overcome RED-S, restore energy balance, and unlock their full performance potential—without the frustration of trial and error.
What is RED-S?
Relative Energy Deficiency in Sport (RED-S) occurs when there is an imbalance between energy intake (diet) and energy expenditure (exercise/training), leading to impaired physiological functioning across multiple systems including:
-
Menstrual function
-
Bone health
-
Metabolic rate
-
Immune function
-
Cardiovascular health
-
Psychological wellbeing
-
Performance outcomes (strength, endurance, concentration, recovery)
RED-S can affect any active individual, regardless of age, gender, or sport.
If left untreated, RED-S can lead to serious health consequences, chronic injury risk, and long-term declines in athletic performance.
Signs You Might Be Under-Fueled & Underperforming
Energy & Performance Decline
❌ Constant fatigue & exhaustion, even after rest days
❌ Struggling to keep up with training loads – workouts feel harder than they should
❌ Hitting a performance plateau or even regressing despite training harder
❌ Loss of strength, speed, or endurance – feeling weaker instead of stronger
❌ Lack of motivation & mental fog – struggling to focus during training or competitions
Emotional & Mental Fatigue
💭 Mood swings, irritability & anxiety – feeling mentally drained all the time
💭 Self-doubt & frustration – questioning why you're not performing how you should
💭 Disordered eating patterns – obsessing over food, calories, or restrictive eating
💭 Fear of fueling properly – worrying that eating more will affect body composition
Recovery & Injury Struggles
⚠ Frequent injuries – stress fractures, muscle strains, or overuse injuries
⚠ Slow recovery – soreness lingers longer than expected, injuries take forever to heal
⚠ Immune system issues – getting sick often or struggling with colds and infections
⚠ Inconsistent performance – some days feel good, others feel like a complete struggle
Long-Term Health Risks of Ignoring RED-S
⛔ Osteoporosis & weak bones – increased risk of fractures & long-term bone health problems
⛔ Hormonal imbalances that take years to fix if not addressed early
⛔ Compromised metabolism, making it harder to recover & regain performance levels
⛔ Increased burnout & mental fatigue, leading to early drop-out from sports
Hormonal & Metabolic Issues
🚨 Irregular or missing periods (for female athletes) – a red flag for RED-S
🚨 Low testosterone levels (for male athletes) – reduced strength, muscle loss & fatigue
🚨 Digestive issues – bloating, irregular bowel movements, or constant gut discomfort
🚨 Struggling to gain muscle or maintain weight, despite eating "enough"
🚨 Metabolism slowing down – body holding onto weight or extreme difficulty gaining lean mass
Are These RED-S Symptoms Holding You Back?
Many athletes push through constant fatigue, injuries, and declining performance without realizing their body is under-fueled. If you’re experiencing any of the following, it’s time to take action.
✅ Constant tiredness & exhaustion, even on rest days
✅ Training hard but seeing no progress – or even getting weaker
✅ Frequent injuries like stress fractures or muscle strains
✅ Slow recovery & persistent soreness after workouts
✅ Irregular or missing menstrual cycles (for female athletes)
✅ Low testosterone levels & muscle loss (for male athletes)
✅ Brain fog, mood swings & lack of motivation
✅ Struggling to maintain or gain muscle, despite eating “enough”
✅ Compromised immune system – getting sick more often
Left untreated, RED-S can lead to long-term damage, including weak bones, hormonal imbalances, and a slower metabolism. The good news? We can fix it.

Your specialist RED-S Dietitian
Unsure if You Have RED-S or Are at Risk?
If you are unsure whether you have confirmed RED-S (Relative Energy Deficiency in Sport) or if you may be at risk, the first step is to book an initial consultation.
During this consultation, your specialist dietitian will conduct a comprehensive RED-S assessment, evaluating your energy availability, training demands, health markers, and any symptoms that may indicate RED-S or risk factors for it.
If you are eligible for our full RED-S Recovery Program, the cost of your initial consultation will be credited toward your program package — meaning your consultation becomes part of your investment in your recovery and performance.
Booking an initial consultation allows you to receive a professional assessment, clarity around your current health status, and personalised advice on the best next steps.
