Steady energy from your food and clear-headed days, in one simple capsule.
- Energy from your food. Thiamine is the B vitamin your body uses to turn carbohydrates into fuel.
- Steady, clear-headed days.
- Helps your body use protein and fat, not just carbs.
- Normal nerve function support.
Why it fits bioenergetic living. Eating for energy often means fruit, sugar, milk and other carbs. Thiamine is what helps your cells burn that fuel instead of stalling. It's simple, high-dose and clean.
What you get:
- 500 mg USP-grade thiamine HCl per capsule, from Germany, filled in the USA.
- One ingredient in a vegetable capsule: no sugar, salt, starch or anything artificial.
- 120 capsules per bottle.
"It is amazing quality," one repeat customer says. Another: "I appreciate the excellent quality of every product I've tried from The Life Giving Store."
Prefer a scoop? Our Vitamin B1 Powder is the same USP thiamine. 60-day no hassle returns.
How to use: 1 capsule a day with a meal, or as your healthcare provider suggests.
Starting out: Some people prefer to start every other day for the first week and settle in from there.
If it doesn't sit right: If you notice an upset stomach or feel off, take it with a larger meal or ease back, and talk with your healthcare provider.
Store cool, dark, and dry; keep closed.

Thiamine and energy from food
Thiamine is a required cofactor in the steps that turn carbohydrate into usable energy. These studies cover thiamine in general, not this exact product.

Higher oral doses of thiamine HCl (the form we sell) raised blood thiamine levels further in healthy adults.
Bioenergetic & low-toxin perspective
Ray Peat put thiamine on his short list of the nutrients closest to cellular energy.
"Riboflavin, coenzyme Q10, vitamin K, niacinamide, thiamine, and selenium are the nutrients that most directly relate to mitochondrial energy production." — Ray Peat, "Rosacea, inflammation, and aging: The inefficiency of stress" (https://raypeat.com/articles/articles/rosacea-inflammation-aging.shtml)
A study Peat cited in "Vegetables, etc.—Who Defines Food?" (https://raypeat.com/articles/articles/vegetables.shtml): Meyer P (1989). Thiaminase activities and thiamine content of Pteridium aquilinum, Equisetum ramosissimum, Malva parviflora, Pennisetum clandestinum and Medicago sativa. Onderstepoort J Vet Res 56(2):145-6. PMID 2748137. Some plants carry enzymes (thiaminases) that break thiamine down, one reason a clean, direct source is useful.
