Saccharomyces Boulardii by Seeking Health contains 5 billion CFU of the yeast Saccharomyces boulardii per capsule, as Lynside® PRO SCB. It is a yeast and not a bacterium, and the capsules can be stored outside the fridge.

Lychees in Indochina

In 1923 the French microbiologist Henri Boulard isolated a yeast from the skins of lychees and mangosteens in what was then Indochina. According to tradition, he saw how people there chewed the skins or made tea from them. The yeast was named after him: Saccharomyces boulardii, a variant of the yeast that is also used to brew beer and make bread rise.

Made in the United States

Seeking Health has Saccharomyces Boulardii made in the United States according to GMP. The yeast is Lynside® PRO SCB from the French yeast company Lesaffre. The capsule is plant-based and the product is vegan.

Facts about this formula

One capsule provides 5 billion CFU, with 250 mg of yeast. Unlike most bacterial strains, this yeast does not need to be kept in the fridge. Take 1 capsule per day, with or without food.

Saccharomyces Boulardii by Seeking Health

Because it is not a bacterium, S. boulardii combines well with other probiotics.

Reviews

What we may claim

For bacterial strains we may claim nothing.

Framework
EU 432/2012
EFSA register
Subject
Bacterial strains
(no claims)

In Europe, we may only make health claims about food supplements that have been assessed and authorised by the EFSA and are listed in the official EU register.

For bacterial strains and yeasts, there is nothing in that register. That is why we only describe here which strains it contains, how much, and how to use and store the product.

No authorised claims
Bacteria and yeasts
Regulation 1924/2006

This page makes no statement about what these bacterial strains or yeasts do in your body.

The EFSA has assessed dozens of applications for bacterial strains and yeasts and has not authorised a single one. What you can read here: which strains it contains, how many colony-forming units (CFU) a capsule contains and how to store the product.

Framework: Regulation (EC) No 1924/2006 and Regulation (EU) No 432/2012. For micro-organisms in food supplements, there are no claims in the EU register and no claims on hold.

AND WHAT WE ARE NOT ALLOWED TO SAY
  • -
    No claim whatsoever about curing, preventing or treating diseases. A supplement is not a medicine and we do not present it as one.
  • -
    No substitute for medical advice. If you take medication, are pregnant or have a medical condition, consult your doctor.
  • -
    No substitute for a varied diet. A supplement is an addition to healthy eating, not an alternative.
AWAITING ASSESSMENT

A scientific assessment by the EFSA is still ongoing for a number of plant substances. Claims for these may be used under a transitional arrangement and are marked on this page as on hold.

About the brand

Seeking Health, briefly explained.

Seeking Health

Nutrition that fits your genes.

Seeking Health was founded by Ben Lynch, naturopathic doctor and author of Dirty Genes. He studied at Bastyr University in Washington and has worked for years with doctors and health professionals who apply insights from epigenetics. His starting point: your genes are not a fixed fate, and with diet and lifestyle you can work with them. Seeking Health is best known for active forms of vitamins, such as methylfolate and methylcobalamin, and for methyl-free variants for those who are sensitive to them.

Quality and production

Active forms, clear choices.

Seeking Health opts for vitamins in the form in which the body uses them and offers a methyl-free variant of many formulas. The products are made in the United States according to GMP and are free of the most common allergens.

Forms
INFO
Active vitamins
Methylfolate, methylcobalamin, P-5-P
Wherever possible, Seeking Health uses vitamins in the form the body can use directly: folate as L-methylfolate or folinic acid instead of folic acid, vitamin B12 as methylcobalamin, hydroxocobalamin or adenosylcobalamin and vitamin B6 as pyridoxal 5-phosphate.
Choice
INFO
Methyl or methyl-free
MF variants without methyl groups
Not everyone tolerates formulas with methyl groups equally well. That is why Seeking Health offers an MF variant, methyl-free, of many products, with folinic acid and hydroxocobalamin, for example. That way you can choose what suits you.
Purity
INFO
Without common allergens
No gluten, dairy or soy
The formulas are free of gluten, dairy and soy and contain no artificial colourings or flavourings. The label of each product states which allergens may be present, such as milk in a whey protein.
Production
INFO
Made in the USA
According to GMP
The supplements are produced in the United States, in facilities that work according to GMP, the guidelines for good manufacturing practice.
