Online consultations for MCAS, menopause, gut issues and any complex chronic conditions.

1:1 expert nutrition built specifically for you

This is for you if:

  • You've been told your test results are normal but something still feels very wrong

  • You're in perimenopause or menopause and feel like your body has changed overnight

  • You have an MCAS, autoimmune or chronic condition that conventional medicine hasn't resolved

  • You still struggle with weight loss, emotional eating or just knowing what to eat.

  • You're exhausted by conflicting advice and just want someone to look at your whole picture

  • You want a plan that's actually built around your life, not a template

How does it work?

Keris Marsden consultation options

I work with clients across the UK and internationally, online via Zoom.

My approach is always integrative and highly personalised.

I look at your full health history, your bloodwork, your lifestyle and your lived experience before making any recommendations.

Whether you're navigating MCAS, perimenopause, menopause, complex gut issues or any chronic symptoms, we start with your whole picture and build from there.

You can choose from any of the consultation options below.

If you are unsure what would benefit you most then simply book a free discovery call and we can take it from there.

Tailored consultation options

12 Week Nutritional Therapy & Wellbeing Package

“Most clients tell me this is the most comprehensive health support they've ever received.”

  • If you're dealing with something complex such as MCAS, chronic gut issues, hormonal disruption, autoimmune conditions, or symptoms that have never been properly explained, this is the package designed for you.

    Four consultations over 12 weeks gives us the time to actually investigate, not just react. We can review bloodwork, track your response to changes, adjust your supplement and nutrition plan as we learn more, and build something that genuinely fits your life, not a template.

    This isn't a quick fix. It's the kind of support that creates real, lasting change.

    Best suited for: MCAS, perimenopause and menopause, complex gut and digestive issues, autoimmune and chronic inflammatory conditions, thyroid dysfunction, hormonal imbalances, metabolic health, weight management and type 2 diabetes.

  • FULL DETAILS

    Here's everything included in your 12-week package:

    4 virtual consultations via Zoom A 60-minute initial consultation followed by three 45-minute follow-up appointments — spaced to give your body time to respond and give us meaningful data to work with.

    4 personalised consultation reports Delivered within 24 hours of each appointment — detailed, evidence-based nutrition and supplement recommendations you can actually refer back to, not rushed notes you can't read later.

    Ongoing email support between sessions Questions come up between appointments. You won't be left waiting six weeks to ask them.

    Blood and functional testing guidance Where relevant, I'll advise on which tests are worth doing, how to access them, and help you interpret the results in the context of your full picture. Laboratory fees are not included.

    Supplement and herb recommendations Targeted, therapeutic and adapted as we go, not a one-size list that stays the same regardless of how you respond.

    Educational resources, meal guidance and movement advice Recipes, portion and macronutrient guidance, and exercise recommendations tailored to your specific health situation and goals.

    GP and specialist correspondence Where needed, I'll liaise with your medical team to make sure everyone is working from the same picture.

    Discounts on professional-grade supplements Access to high-quality supplements from trusted manufacturers at a preferential rate.

    Free access to the Mindful Body Method As part of your package you'll get full access to resources in the membership community — including yoga, meditations, workshops, mindset support and a community of people on a similar journey.

Single Nutritional Therapy & Wellbeing Initial Consultation

  • A single consultation is a good option if you do not need the ongoing support (and you can simply book a follow up when needed).

    Or you have a healthy foundation in place already and just need an MOT or some fine tuning

    Suitable for: weight loss, PMS, migraines, prenatal nutrition, PCOS, endometriosis, skin issues, sports performance, supplement advice, digestive issues, autoimmune conditions, thyroid issues, heart disease and diabetes.

  • A single 60-minute virtual consultation.

    An in-depth consultation report detailing personalised and evidence-based nutrition and exercise recommendations and a supplement plan (provided 24hrs after your consultation).

    Educational resources, recipes, portion/macronutrient guidance and exercise plans where applicable.

    10% discount on high quality supplements from trusted manufacturers.

Expert Power Hour

  • A focused 60-minute session for a specific question or goal.

    This is ideal if you have a clear area you want expert guidance on and don't need ongoing support.

    Perfect for a supplement review, a nutrition MOT, or guidance before a GP or specialist appointment.

    Please note this option doesn't include a follow-up report, so come ready to take notes.
