Products Gillian actually recommends to her clients

After 30 years in clinical practice, Gillian has identified the supplements, tools and foods that genuinely make a difference. Every item here is something she recommends in her clinic or uses herself — nothing more, nothing less.

Gillian Killiner BSc MSc RD — Specialist Registered Dietitian

"I only recommend products I'd be confident suggesting to a patient sitting in my clinic. If it's here, it's because the evidence — or my 30 years of experience — supports it."

BSc (Hons) MSc RD · Specialist Registered Dietitian

⭐ Most Popular Programme

The 121 Gut Health Programme

A structured 4–6 week dietitian-led plan combining FODMAP, gut microbiome support and tailored coaching — proven to reduce bloating, IBS symptoms and food anxiety.

⭐ Gillian's Top Picks

The clinic essentials — where Gillian would start

If a client asked Gillian "what should I buy first?" — these are the products she returns to most often across her conditions and programmes.

⭐ Top Pick
Alflorex Probiotic
Gut Health
Alflorex Probiotic with Bifidobacterium 35624

"This is the only probiotic strain with robust clinical evidence specifically for IBS. I recommend it regularly in my FODMAP programmes — the strain matters enormously with probiotics."

⭐ Top Pick
BetterYou D3 K2 Spray
Hormonal Health
BetterYou Vitamin D3 + K2 Oral Spray

"Vitamin D deficiency is extremely common in Northern Ireland and the UK, and contributes to fatigue, low mood and immune issues. The spray form is better absorbed than tablets — especially if gut health is compromised."

View on Amazon →
⭐ Top Pick
Magnesium Glycinate
Gut & Sleep
Magnesium Glycinate 300mg Capsules

"Magnesium glycinate is the form I recommend most — highly absorbable and gentle on the gut, unlike magnesium oxide. Particularly helpful for IBS-C, poor sleep, and stress-related gut symptoms."

View on Amazon →
⭐ Top Pick
Squatting Stool
Gut Health
StrongTek Bamboo Squatting Toilet Stool

"Clients are often surprised when I recommend this — but squatting position genuinely aids complete evacuation and reduces straining. One of the simplest, most evidence-backed things you can do for constipation."

Gillian's note on supplements

"I always recommend food first — but supplements can play an important role when diet alone can't fill gaps, particularly for people with gut absorption issues, restricted diets, or specific health conditions. Please check with your healthcare professional before starting new supplements, especially if you're on medication."

Alflorex
Gut Health
Alflorex + Calcium Probiotic (35624 strain)

Energy & Mood
Igennus Super B-Complex (methylated, sustained release)
