Hello. I have a question about vitamin B1. I just realized that B1 vitamins can be different. Some in the ingredients say thiamine mononitrate, some say thiamin hydrochloride and some like Solgar company say Vitamin B1 (as thiamin hcl). Does that mean that solgar sells "natural" vitamin B1? Also one of the ingredients of Solgar B1 vitamins is silica. Doing some research I think this is not a very good component. " Why is Silica Hazardous?
Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.
The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles. These dust particles are very small. You cannot see them. This respirable silica dust causes lung disease and lung cancer. It only takes a very small amount of airborne silica dust to create a health hazard."
What company B1 would you recommend. My dad is currently taking Spring Valley B1, but I think this is a synthetic version vs natural. Thank you.
