Overview: Product Description

Vitamin B1 is a premium brain‑health supplement designed to support memory, attention, mood stability, and overall cognitive vitality. It delivers a concentrated dose of thiamine (Vitamin B1) to help reduce cognitive decline, enhance mental clarity, and promote neurological wellness. Whether you struggle with “brain fog”, fluctuating mood, or waning concentration, this memory support formula offers a daily capsule-based solution to sharpen focus, stabilise emotion, and maintain optimal brain function. Developed by Doc Frank at Integrow Health, Vitamin B1 is ideal for adults who want to optimise brain health, support memory, and maintain mental resilience as they age.

Why Vitamin B1?

Modern lifestyles place enormous stress on brain performance and mood stability due to factors such as stress, poor sleep, inflammation, and nutrient deficiencies. Many adults experience declining memory, harder focus, mood swings, or slower cognitive processing. Standard diets often do not supply sufficient thiamine, an essential nutrient for energy metabolism, nerve function, and memory support. Vitamin B1 meets this need: by providing a highly bioavailable dose of thiamine, it supports neural energy production, maintains proper neurotransmitter function, and helps preserve cognitive performance, filling the gap between everyday nutrition and advanced brain-health maintenance.

"Vitamin B1 (Thiamine) is essential for energy production, brain function and a resilient nervous system."

Vitamin B1 (Thiamine) 100 mg x 90 tablets
An excellent product – noted a consistent increased baseline energy level after taking supplement for about a month; (might have taken this long due to my age 🙂 )sleeping better as well. After two months of daily use can testify that with eating moderately, but not cutting out all sugars, I have been able to slowly but surely get rid of some excess weight – noted an increase in hunger pangs, which just must be handled wisely. My husband also noted better levels of concentration with regular use.

I’ve been giving my children Vitamin B1 and I’ve really noticed the difference. Their energy levels are more consistent throughout the day, and they seem more focused and less irritable. I feel reassured knowing B1 supports their nervous system and overall growth.
