Why choose Berberine + Grapefruit Seed?

A high-strength herbal complex designed to support a healthy microbial balance in the gut, ideal for those looking to cleanse the gut of unwanted pathogens

The constituent herbs have been studied for their effectiveness in helping to clear unwanted organisms such as parasites and bacteria from the gastrointestinal tract thereby helping to support gut health. Studies continue to show the importance and the impact of healthy gut micro-flora.

Our Berberine + Grapefruit Seed formula offers an array of potent herbal compounds standardised to provide a guaranteed potency of each of the active components. It differs from other antimicrobial formulas on the market due to the sheer diversity of compounds provided in the formula, and therefore can be considered to be an extremely potent and effective combination.


Why are standardised extracts important?

A standardised herbal extract is a specific concentration of one or more of the chemical compounds found in the plant.
It guarantees that the potency and amount of active compounds contained in the product is the same as those advertised on the label and is consistent from batch to batch.
With standardised herbal extracts, you know you're getting a sufficient amount of the beneficial compound, as determined by scientific evidence.


Which herbs does it contain and why?

The herbs in this formula have traditionally been used to help maintain a balance of micro-flora in the gastrointestinal tract. If the gut micro-flora is imbalanced, this may have a negative impact on overall health, and may for example compromise your nutrient status, or negatively affect your immune system. Research has gathered apace over recent years regarding the necessity of maintaining a healthy gut environment, or microbiome, for overall health and wellbeing.

  • Berberine is a yellow-coloured alkaloid that is found in certain plants such as Goldenseal, Barberry, Oregon Grape, Chinese Gold Thread and Phellodendron. It has a 3000-year history of use in Traditional Chinese Medicine.
  • Grapefruit seed extract is a substance derived from the seeds, membranes and the pulp of grapefruit. It is used to support microbial balance in the body.
  • Garlic has been used traditionally for centuries. It may help defend against harmful micro-organisms such as bacteria and fungi in the gut, and may also support the immune system.
  • Goldenseal has been used traditionally to contribute to the natural defences of the body.
  • Gentian is a bitter digestive herb that is traditionally used to facilitate and support digestion.
  • Sweet Annie and Black Walnut are also part of this synergistic herbal formula.
