About Crystal Mendes

About me

It all began in the beautiful countryside of South Devon, where I grew up. My mum taught me early on to harness the power of food – raising me on organic local produce and sharing her passion for maintaining health and vitality through lifestyle.

It wasn’t until I experienced Chronic Fatigue Syndrome in my teens that I really understood the benefits of nutrition and complimentary therapies first-hand. CFS wasn’t a widely accepted or understood condition at the time so it was up to me to find my way through it and, after six years of research, good nutrition and supportive therapies, I began to heal.  

Fast-forward over a decade and I’m now a fully qualified, registered Nutritionist after studying for 3 years at the renowned College of Naturopathic Medicine in London. I’m also a member of BANT (British Association for Applied Nutrition and Nutritional Therapy) as well as the CNHC (Complementary and Natural Healthcare Council).

I specialise in supporting women experiencing fatigue during perimenopause. This work holds deep personal meaning for me, as it is a journey, I understand first-hand. I know how disruptive and debilitating symptoms associated with perimenopause can be. Both physically and emotionally. 

Through my work using a personalised, food-first approach with the Metabolic Balance® programme, I’ve seen how transformative the right nutritional support can be. When the body is given what it truly needs, energy can begin to stabilise, clarity can return, and everyday life can start to feel more manageable again.

The Perimenopausal journey is multifaceted, however, and I’m passionate about supporting my clients through any of the following challenges (and more!):

Energy & Fatigue

  • Persistent fatigue and low energy
  • Difficulty maintaining motivation or focus
  • Brain fog and memory lapses

Hormonal & Reproductive Changes

  • Fluctuating hormone levels (oestrogen, progesterone)
  • Hot flashes and night sweats
  • Mood changes, anxiety, or low mood
  • Libido changes and vaginal dryness

Metabolic & Weight Management

  • Weight gain or changes in body composition
  • Blood sugar swings and insulin sensitivity issues
  • Appetite changes

Digestive & Gut Health

  • Bloating, constipation, or irregular digestion
  • Food sensitivities or histamine intolerance
  • Reflux / heartburn

Skin, Hair & Inflammatory Responses

  • Flushing, itching, eczema, or other inflammatory skin conditions
  • Hair thinning or shedding
  • Dry skin and hair changes

Sleep & Recovery

  • Difficulty falling asleep or staying asleep
  • Early waking or non-restorative sleep

Immune & Overall Wellness

  • Slightly increased susceptibility to minor infections
  • General inflammation or sensitivity to environmental triggers
  • Joint stiffness or mild aches

Thyroid & Endocrine Support

  • Perimenopause can unmask or exacerbate thyroid imbalances, affecting energy, metabolism, and mood

My ambition is to empower women with the tools they need to take charge of their health from the inside out. Through the right nutrition, I believe every woman has the ability to feel their absolute best and that’s what I’m here to help you do.

Why Work With Me

I work closely with women to navigate the challenges of perimenopause with clarity and confidence. I understand that fatigue, brain fog, and fluctuating energy aren’t just inconvenient, they can feel overwhelming. That’s why my approach is always personalised, practical, and rooted in real science.

Using a food-first strategy with the Metabolic Balance® programme, I tailor nutritional guidance to your unique body and lifestyle. I don’t believe in one-size-fits-all solutions; instead, we work together to create sustainable changes that truly support your energy, mood, and overall hormone balance.

With my guidance, you gain more than a plan, you gain understanding, support, and a clear path forward. My goal is to empower you to feel more in control of your health, so fatigue doesn’t hold you back from living the life you want.
