Vitamin B1 (Thiamine) 100mg x 90 capsules
Sold out
Description
Health Leads Vitamin B1 provides 100mg of thiamine in each vegetarian capsule.
Thiamine, also known as Vitamin B1, is an essential water-soluble vitamin that the body cannot produce itself. Because only small amounts are stored, it must be obtained regularly through the diet or supplementation.
Vitamin B1 contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, and normal heart function, as recognised by authorised UK and EU nutrition and health claims.
What Is Vitamin B1?
Vitamin B1, or thiamine, was the first B vitamin to be identified, giving rise to its name.
It belongs to the family of water-soluble B vitamins, which are involved in a wide range of normal metabolic processes.
Unlike fat-soluble vitamins, thiamine is not stored in significant amounts within the body, making regular intake from food important.
Where Is Thiamine Found?
Vitamin B1 occurs naturally in a variety of foods, including: Wholegrain cereals, Brown rice, Legumes, Lentils, Beans, Peas, Sunflower seeds, Pork, Yeast extract, Fortified breakfast cereals.
Cooking and food processing can reduce the thiamine content of some foods, which is one reason fortified foods and supplements are commonly used.
How Does Vitamin B1 Work?
Thiamine functions as a coenzyme that helps enzymes release energy from carbohydrates consumed in the diet.
This role underpins one of its best-known authorised health claims: Vitamin B1 contributes to normal energy-yielding metabolism.
Rather than providing energy itself, thiamine supports the body's normal ability to convert food into usable cellular energy.
UK & EU Authorised Health Claims
Vitamin B1 contributes to:
Normal Energy-Yielding Metabolism — helping the body release energy from carbohydrates, fats and proteins as part of normal metabolism.
Normal Functioning of the Nervous System — supporting the normal function of the nervous system.
Normal Psychological Function — contributing to normal psychological function.
Normal Heart Function — supporting the normal function of the heart.
These claims are authorised for Vitamin B1 under UK and EU nutrition and health claim legislation.
Why Does This Product Provide 100mg?
The Nutrient Reference Value (NRV) for Vitamin B1 is 1.1mg per day for adults.
The NRV is intended to represent an intake sufficient to meet the needs of most healthy adults and to help prevent deficiency.
Many food supplements provide amounts above the NRV. Thiamine is a water-soluble vitamin, and the body does not store large quantities. Any excess is generally excreted in the urine, and no tolerable upper intake level has been established for healthy adults by European authorities.

Frequently asked questions
-
Vitamin B1 (Thiamine) contributes to several normal functions in the body that are supported by EU-authorised health claims. These include normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, and normal heart function. Thiamine plays a particularly important role in the metabolism of carbohydrates for energy production.
-
The EU Nutrient Reference Value of 1.1mg is set to prevent deficiency in the general population. Higher doses are commonly used in supplementation for specific purposes. Vitamin B1 is water-soluble, meaning the body excretes what it does not use rather than accumulating it, which makes it well tolerated at higher doses. There is no established EU tolerable upper intake level for Thiamine, reflecting its low toxicity profile.
-
Yes, but be mindful of your total daily intake across all supplements. The Health Leads Vitamin B Complex already contains 90mg of Vitamin B1 per capsule. If you are taking both products simultaneously, your combined B1 intake will exceed 190mg per day. This is not considered harmful given B1's water-soluble nature, but it is worth being aware of your total intake across all supplements.

Each bottle contains 90 capsules. At the suggested use of 1 capsule per day, this provides a 90-day supply.
