Vitamin B1

Spruce water is high in Vitamin B1. Vitamin B1, also known as Thiamine, plays a critical role in energy metabolism and helping all tissues in our body function properly.


Vitamin B refers to several different types of vitamins that, together, are known as the B-complex vitamins. There are eight B Vitamins in total: B1, B2, B3, B5, B6, B7, B9 and B12. Spruce contains a nutritionist-approved and professionally crafted mix of five B vitamins; we have selected these five to give you the optimum range of benefits.


Vitamin B1 is a water soluble vitamin and an essential nutrient, often referred to as thiamine.  B1 was the first B Vitamin discovered by scientists… hence its name.

Vitamin B1 is naturally present in several different types of food, as well as being a common dietary supplement. Humans store B1 primarily in the liver, but only in small amounts, meaning we need a continuous supply of Vitamin B1 in our diets.

Spruce is high in Vitamin B1, and thiamine is considered a bit of a workhorse in vitamin circles. B1 is perhaps best known for helping the body turn food in to energy. The body needs thiamine to make adenosine triphosphate (ATP) - a molecule that transports energy within cells.

Key benefits of Vitamin B1:

  • Vital for metabolism
  • Growth, development and function of cells
  • Helps support the immune and nervous system
  • Helps support our brains
  • Helps support normal cardiovascular function
  • Contributes to normal psychological function

Given B1 plays a critical role in energy metabolism, it therefore is very important for the growth, development, and function of cells. Besides being a metabolism booster and helping us keep the light on, Vitamin B1 has other benefits, and plays a key role in nerve, muscle, and heart function.

Sources of Vitamin B1

Vitamin B1 is naturally found in a wide range of meats, vegetables and grains. B1 can be found in pork, poultry, peas, nuts, rice, whole grain cereal, lentils and even some breads.

While Vitamin B1 is widely accessible in most diets, it is the vitamin workhorse, and you wouldn’t be a multivitamin without it. So we are chuffed Spruce is high in Vitamin B1 and helps on our quest for natural and healthy hydration.


The RDA, or NRV (Nutritional Reference Value), for Vitamin B1 in adults is 1.1 mg (milligram) daily in the UK and EU. One made up Spruce contains 0.5 mg (45% of NRV), meaning you can enjoy multiple Spruce drinks in a day.

Vitamin B1 is considered a very safe vitamin and NHS say that taking “too much” will unlikely cause any harm. It is always best to check with a doctor before taking a supplement, especially if you have an existing health condition, or if you are pregnant or breastfeeding.
