### ⭐⭐⭐⭐⭐ Great for after extended fasting.
*by D***N on September 1, 2025*

### ⭐⭐⭐⭐⭐ Review

Excelente calidad y precio

### ⭐⭐⭐⭐ definitely bitter and no guidance with serving size ex no idea # milligrams in an 1/8 teaspoon
*by W***F on March 19, 2025*

got the thiamine HCI bag, but it has no guideline as to milligram equivalency. someone noted that 1/16 teaspoon is roughly = 100mg dose (so 1/2 tsp would be 800mg), another noted that a 1/2 teaspoon is roughly = 1250mg. which of those is more accurate? ultimately, i need to know what a 1/8 teaspoon is equal to as that is the smallest serving spoon i have. i got the bag to do mega high doses to counter a big B1-deficit confirmed by various tests incl genetic microbiome (as a result i have daignosis of stage 2 parkinson's). and it has a bitter taste that some 'no taste' folks apparently cant taste. i wrote bulksupplements.com to ask for more measurement info. when they answer, i'll update/edit this review.
