Strath is a remarkable supplement with an 80-year history, a devoted following across Europe, and a unique production process unlike anything else on the supplement market. If you've been searching for Strath Ireland or Strath herbal yeast, Pat Coffey at The Honey Pot in Clonmel stocks both the liquid tonic and tablet form of this iconic Swiss product — and has recommended it to Irish customers for conditions ranging from fatigue and poor concentration to children's nutritional support and elderly wellbeing.
What Is Strath?
Strath is a fermented herbal yeast supplement made in Switzerland by Bio-Strath AG. It is produced from a very specific strain of Saccharomyces cerevisiae yeast, cultured together with 11 medicinal herbs including thyme, chamomile, lavender, valerian, lemon balm, liquorice, peppermint, and elderflower. The yeast absorbs the active constituents of the herbs during fermentation, then undergoes plasmolysis — a process where the yeast cell walls are broken open using a gentle enzymatic technique, releasing the intracellular contents including amino acids, vitamins, minerals, coenzymes, and herb-absorbed phytonutrients.
The result is a liquid whole-food concentrate containing over 60 nutrients in a highly bioavailable form — including all B vitamins, trace minerals, essential amino acids, nucleotides, and a wide range of herbal phytonutrients.
Why Plasmolysis Matters
The plasmolysis process is what makes Strath genuinely unique. Whole yeast products (like brewer's yeast) have limited digestibility because the cell walls of Saccharomyces cerevisiae are composed of tough beta-glucan polysaccharides that resist digestion in many people. Plasmolysis opens these cells, making all the intracellular nutrients immediately available for absorption. The resulting product is:
- Easily digested by people of all ages including infants and the elderly
- Suitable for people who find whole yeast products difficult
- More bioavailable than dried yeast powders or tablets made from intact cells
- A true whole-food supplement — not isolated nutrients added to a base
Strath's Nutrient Profile
Strath provides a remarkably broad spectrum of nutrients in natural, food-matrix form:
- All B vitamins (B1, B2, B3, B5, B6, B7, B9, B12)
- Essential amino acids — all 9, including lysine, methionine, tryptophan
- Non-essential amino acids in significant amounts
- Trace minerals — zinc, selenium, manganese, chromium, molybdenum
- Coenzymes and enzyme precursors
- Nucleotides (RNA and DNA building blocks)
- Herb-derived phytonutrients from the 11 fermentation herbs
Who Uses Strath — Common Applications at The Honey Pot
Pat Coffey has recommended Strath to a wide range of customers over the years:
- Chronic fatigue: The B-vitamin and amino acid profile makes Strath particularly valuable for energy metabolism. Many customers with long-term fatigue (including post-viral fatigue and ME/CFS) find Strath supports their energy levels alongside other interventions.
- Children's nutrition: Strath is one of the few whole-food supplements appropriate for young children. It has been used by Swiss families for generations as a nutritional tonic for picky eaters, growing children, and those recovering from illness.
- Elderly nutritional support: Appetite and nutrient absorption often decline with age. Strath's liquid form and comprehensive profile makes it ideal for elderly people who struggle with eating well or absorbing nutrients from food.
- Convalescence and recovery: The complete amino acid and nutrient profile supports recovery from illness, surgery, or periods of physical depletion.
- Athletes and physical training: Several Swiss clinical trials with athletes show Strath improves physical performance and reduces recovery time.
- Stress and concentration: B vitamins, especially B5, B6, and B12, are essential for adrenal function and neurotransmitter synthesis. Many Irish students and professionals use Strath for mental clarity during demanding periods.
Clinical Research on Strath
Bio-Strath has funded and published clinical research on their product, including:
- A double-blind study showing Strath supplementation improved physical performance indicators in athletes
- Studies in children showing improvements in concentration, appetite, and school performance
- Research in elderly populations showing reductions in fatigue and improvements in quality of life
How to Take Strath
- Liquid tonic: Adults 3 teaspoons (15ml) 3x daily before meals. Children over 1 year: 1 teaspoon 3x daily.
- Tablets: 3 tablets 3x daily before meals
- The liquid form has a characteristic yeasty-herbal flavour — most people find it pleasant or at least easy to take in juice or water
- Can be taken long-term — no upper duration limit
