Supplements for gut health, explained simply.

Your gut affects digestion, mood, immunity, even skin. The good news: the most powerful "supplement" here is food. Here's the beginner version.

A healthy gut is built mostly from variety and fibre in your diet, plants, beans, whole grains. Supplements can support that, but they work best alongside real food, not instead of it.

The basics that actually matter

Feed the good bugs.

Fibre (prebiotic) Strong-ish evidence

Food for the friendly bacteria in your gut.

The single most reliable way to improve gut health. A supplement can help if your diet is low, add it slowly.

Probiotics Moderate evidence

Live "good" bacteria in a capsule or food (like yogurt).

Helpful in specific situations, after antibiotics, or for certain digestive complaints. The right strain matters more than the brand.

Omega-3 (fish oil) Moderate evidence

Healthy fats that calm inflammation.

Supports a healthier gut lining and overall inflammatory balance.

Vitamin D Emerging evidence

The "sunshine" vitamin, with a role in gut immunity.

Low levels are linked to gut issues; correcting a deficiency may help.

Play it safe
