Similase is back with a new name and brand-new packaging under Metagenics, delivering the same expert formula you trust.

MetaDigest® Triple Action is a comprehensive digestive support formula that combines fast-acting plant enzymes with ginger root extract to naturally support the breakdown of food. Whether you're dealing with occasional bloating, heaviness, or nausea after meals, this triple-action blend targets carbohydrates, fats and proteins to help ease digestion and reduce discomfort.

With enzymes that remain active in both acidic and alkaline environments, it works in any stomach condition. Perfect for anyone experiencing sluggish digestion, enzyme deficiency, or occasional nausea – and all in a single, easy-to-take capsule.

Similase has now been discontinued, but don’t worry, MetaDigest® Triple Action is here as its expertly-designed replacement. While both formulas support healthy digestion, MetaDigest® offers a more targeted and fast-acting approach, making it an excellent option for if you were previously using Similase.

Similase is a broad-spectrum blend of plant-based enzymes like protease, amylase, lipase, lactase, and cellulase, plus artichoke extract to support overall digestion, and was ideal for comprehensive support across all food groups, including fibres and dairy.

New MetaDigest® Triple Action builds on this foundation with fast-acting enzymes that start working immediately in the stomach, combined with ginger root extract to help relieve bloating, heaviness, or nausea after meals. It’s especially beneficial for those with sluggish digestion or occasional post-meal discomfort.

Digestive enzymes are produced naturally by the body and act as catalysts to break down food so our bodies can absorb essential nutrients and utilise them for growth, repair and energy.

MetaDigest® Triple Action is suitable for anyone requiring extra support for digesting proteins, fats, and carbohydrates. MetaDigest® Triple Action is suitable for those with digestive conditions, and can be used daily, or for occasional use after over-indulging.

Different organs in the digestive system function at their own optimal level of pH. For example, the stomach requires a low (acidic) pH to break down food and destroy germs, whilst the intestine has a higher pH because the enzymes that ‘work’ there need an alkaline environment to work efficiently.

MetaDigest® Triple Action is a high potency, broad-spectrum formula that works in a range of pH conditions from 2-12, to support optimal digestion of proteins, carbohydrates and fats.

It works very well as part of a 5R gut restoration programme and can be taken alongside our other popular digestive products, including our UltraFlora® range of probiotics.

Digestive enzymes are needed for the breakdown of the food we eat, and are produced by our bodies and secreted into the digestive system. However, as we age, or during periods of illness, our enzyme activity may decline, and as a result, the breakdown and therefore the absorption of vital nutrients may be compromised.

Taking a supplement containing enzymes such as protease, lipase and amylase can help to support optimal breakdown of the nutrients in the food we eat.

Digestive enzymes, taken with or at the start of a meal, will begin their work breaking down proteins, carbohydrates and fats immediately, and so you may notice an effect from the very first time you take them.

MetaDigest® Triple Action can be taken over a number of weeks or months, particularly if suffering long-term issues like bloating or flatulence, but as there may be underlying factors causing these issues please "ask a nutritionist" to discuss in more detail.

Our new label design has been introduced to help you to find a product that’s right for you, simplifying the way you navigate our range. The new labels provide you with more product information and better highlight the core benefit of each product. For example, you will see new health need colours and descriptions that make it easier to identify ranges and highlights the products main benefit.
