Gut & Immunity
Daily nutritional support for gut and immune health with live cultures, vitamins and minerals.
GUT BALANCE
IMMUNE SUPPORT
EVERYDAY RESILIANCE
- Supports digestion and immune health
- 14 live bacterial cultures important for a healthy, balanced microbiome
- Immunity-supporting vitamins and minerals often lacking in UK diets after 50
Around 70% of your immune system is in your gut, which makes gut health central to your immune resilience. As we age, natural changes in the gut microbiome called dysbiosis can upset the balance of beneficial bacteria.
At the same time, UK nutrition data shows that many adults over 50 fall short of key vitamins and minerals that support immune function. Maintaining a healthy gut helps support digestion and everyday immune resilience.
Gut & Immunity supports both a healthy digestion and a resilient immune system with a blend of live cultures, vitamins and minerals tailored for adults 50+.
Strengthens your body’s natural defences – About 70 percent of your immune system is in your gut. Gut & Immunity supports it with a blend of friendly live bacteria and immune-supporting nutrients often missing from 50+ diets – including iron, vitamins D and C and selenium.
Restores a balanced gut microbiome for healthy digestion – with 14 strains of live bacterial cultures including Lactobacillus and Bifidobacterium, to encourage a healthy, regular digestion and a diverse microbiome. Two billion colony-forming units (CFUs) in every capsule.
Includes our Healthy Ageing Blend – a blend of vitamins and minerals often lacking in 50+ diets but important for general health as we age, including muscle function, heart health, blood sugar balance, immune resilience and cellular protection.
Supports nutrient absorption – with easy-to-absorb mineral forms, plus Bioperine®, a patented black pepper extract shown to increase the absorption of vitamins and minerals, which can become harder for the older gut.
Take one capsule per day with a cold drink at meal times.

Who’s it for?
Gut & Immunity is suitable for all adults aged 50+ who want to support healthy digestion and strengthen their everyday immune resilience.
If you’ve recently taken antibiotics, it can help to restore your gut microbiome balance. It can also help if you experience digestive discomfort from time to time, or feel your immune health is under pressure due to stress, disrupted sleep or a busy routine.
The Healthy Ageing Blend
Most supplements in the Prime Fifty range include our Healthy Ageing Blend: important vitamins and minerals often lacking in 50+ diets, according to UK diet and nutrition data.
The blend includes vitamin D to support bones, muscles and immunity, B vitamins for energy and a healthy heart, zinc for immune and cognitive support, antioxidants to help protect cells from oxidative stress, and chromium for healthy blood sugar balance. Where possible, these important nutrients are always added, no matter which health area you’re targeting.
Together with BioPerine®, a patented black pepper extract shown to support absorption, these nutrients build a strong foundation for your health as you age.
"About 70 percent of our immune system is located in the gut, so maintaining a healthy microbiome becomes even more important as we get older. I designed this formulation to combine carefully selected friendly bacteria with key immune-supporting nutrients that many over-50s are lacking, to support both digestive health and everyday resilience."
The balance of the gut microbiome is very sensitive to what we eat, and an unbalanced gut flora is linked to numerous health problems. We’ve added SynBalance®, a live culture, multi-strain blend of bacteria to help re-balance your gut microbiome.
This special blend includes 14 clinically tested strains, including Lactobacillus and Bifidobacterium, to encourage a healthy, regular digestion and a diverse microbiome, with two billion colony-forming units (CFUs) in every capsule. Plus we’ve added calcium to help digestive enzymes break down and absorb nutrients from your food.
Ingredient highlights
Vitamin A, vitamin D, vitamin C, folic acid, vitamin B12, iron, copper and selenium all help support the normal functioning of your immune system.
Ingredient highlights
Nutrition isn't just about what you put into your body, it’s about what your body can actually use. Breaking down and absorbing nutrients from what we eat becomes harder as we age, caused by reduced stomach acid and other factors. That can affect how well we extract vitamins and minerals from both food and supplements.
That’s why we include BioPerine®, a patented extract of piperine from black pepper shown by multiple studies to enhance the bioavailability of a wide range of vitamins, minerals and other nutrients, helping your body put them to use.

How long until I feel a benefit?
This can vary from person to person, and also depends on the product and the benefit you're looking for. Supplements aren't pharmaceutical drugs, and they won't have an immediate effect.
Some supplements work in the background, delivering long-term health benefits without noticeable short-term differences.
But for most products, the active ingredient in your supplement needs to build up to sufficient levels in the body to begin to have an effect. In general, you should notice a benefit after 4-8 weeks of supplementation.
If you have a question about a specific product, please contact our Customer Care team for more detailed advice. hello@primefifty.com
