Who can benefit from Lynside® Forte B?

In foods, B-vitamins are only present in small amounts, they are not stored in sufficient quantities by the body, and must be constantly replenished. Therefore B-vitamins are especially important for:

  • Vegetarians who are at a higher risk of developing clinical symptoms related to vitamin B12 deficiency (1).
  • Older individuals who may need to supplement their intake due to problems of absorption (2)(3).
  • Athletes or highly active individuals who have an increased need for energy production.

How is Lynside® Forte B made?

Lynside® Forte B is a nutritional yeast in powder with a high content of B-vitamins. It is derived from a pure culture of Saccharomyces cerevisiae. After the yeast is carefully grown, it is harvested, washed with purified water, and then gently pasteurized to preserve its properties. Finally, 8 B-vitamins are added to the cooled yeast in a controlled manner before being drum-dried, allowing delivery of a high-quality 8-vitamin fortified yeast cocktail.

How can you use Lynside® Forte B?

Lynside® Forte B is a high homogenous fortified yest that can be used as a powder for tablets and capsules, alone or blended with other ingredients.
