Est. 1967 Conversion of Food Into Energy Dietary Supplement Sodium Free
Suitable For Vegetarians Gluten Free Soy Free Mason Guarantee - Laboratory Tested cGMP - Certified Good Manufacturing Practice What if you ate plenty of delicious food and yet had very little energy? That is how you might feel if you were severely deficient in any of the B-complex vitamins. Vitamin B1, along with B2, B12 and niacin are essential nutrients that play important roles in energy production, particularly in the metabolism of carbohydrates, fats and proteins. Without sufficient B1, you would feel weary, fatigued, and find it hard to function normally. The B vitamins are in a family of nutrients called coenzymes that help enzymes perform essential chemical reactions. This helps energy production, but also reactions critical to the function of neurotransmitters, hormones, digestive enzymes, mineral metabolism, and many more. Vitamin B1 helps to support the health of the central nervous system, cardiovascular system, pulmonary system, immune system and muscle function, which is why it is considered essential.

Vitamin B-1
Vitamin B1 plays an important role in the metabolism of carbohydrates and the production of energy, which is necessary for all cells of the body, but especially for the neurons of the brain. The functioning of the central nervous system depends entirely on the metabolism of carbohydrates. Vitamin B1 can exhibit antioxidant properties, protecting cell membranes from the toxic effects of peroxidation products.

I am taking B1 because I didn’t sleep well. A doctor suggested me to take B1. It is not perfect but it does help me to get some quality sleep. The quality is good so I will keep taking.

I've been taking these for a few months now to help with my energy levels, and the difference has been honestly surprising. I don't feel that usual 3 PM slump anymore, and my mood just feels more steady throughout the day. The tablets are a bit on the larger side, but they're still manageable to swallow with a big glass of water. For the incredibly affordable price, this is one supplement I'll definitely keep repurchasing.
