Colostrum-fuelled renewal at the cellular level
Backed by research, LOUSTRA™ combines grass-fed bovine colostrum with antioxidant-rich aronia to create a simple daily ritual that supports immunity, gut health, energy, and skin vitality.
Rich in bioactive proteins and polyphenols, Vital Tonic: Colostrum + Aronia promotes cellular renewal, strengthens your body’s natural defences, and helps maintain balance through training, travel, and everyday life - so you feel stronger, more focused, and radiant each day.
Why Colostrum?
Colostrum is nature’s original superfood
Colostrum is packed with over 250 active compounds, including antibodies (IgG, IgA, IgM), lactoferrin, proline-rich peptides, and natural growth factors.
These work together to balance the immune system, support a healthy gut, fight unwanted microbes, repair tissues, and stimulate the body’s natural collagen production for skin and joint health. Once only available in early life, concentrated colostrum now delivers wide-ranging support for resilience, performance, and longevity.
The Benefits

Colostrum strengthens all four layers of the gut barrier while aronia reduces inflammation and supports microbiome balance.
