People behind Tenebra
Meet Jiří and David. Two college students who got tired of overpriced, underdosed supplements.. So they decided to built something better.
What is our purpose?
Most supplements on the market are built for margins, not results. Cheap mineral forms, hidden fillers, zero transparency.
We started Tenebra because we couldn't find a magnesium we actually trusted. So we spent months researching forms, dosages, and manufacturing standards until we built one ourselves.
Our purpose is simple make the supplement we wished existed. Nothing more.
Why Supplements?
We're college students and athletes. Thanks to hard trainings and school our bodies were constantly running on empty.
What we found on the market was disappointing. Oxide forms that barely absorb. Overpriced imports. Products built for profit, not performance.
So we built Tenebra. Started with magnesium, the mineral we both kept coming back to. Researched every form, every dosage, every standard. Then built the product we wished existed.
If you train hard and refuse to settle, this was made for you.
Our Goal is simple:
To give everyone access to supplements that are formulated properly, priced fairly, and backed by full transparency. No compromises.
