About Us

We are a small family business making a short range of food supplements. We keep the range small on purpose, so we can put our time into getting each formula right.

We started Epsilon Life to bring the UK a better vitamin D supplement. Today our supplements are also popular on Amazon UK, where many of our customers buy them.

Our range is led by our unbuffered Chelated Magnesium Glycinate, alongside Vitamin D3 K2 with Zinc, Boron and MCT Oil, NAC+ with Selenium and Molybdenum, and Biome Bliss, a naturally fermented liquid supplement.

Our capsules contain no magnesium stearate, titanium dioxide or artificial fillers, and our labelling tells you exactly what is in every pot.

Where our supplements are made

Our capsules are made, tested and packed in the UK. Many brands buy capsules in bulk from overseas and only pack them here. We don’t.

Biome Bliss is made in the EU to IFS and HACCP standards.

Product quality

  • Capsules are packed straight after manufacture.
  • Our capsules are made in small batches and we hold minimal stock, so what you receive is freshly made.
  • Every pot has a batch number, so we can trace it back to when it was made.
  • Every pot has a Best Before End date. Until that date, we guarantee the nutrient levels declared on the label.

How we work

  • We research every ingredient before we launch a product, and share much of that research in our guides.
  • We don’t chase supplement fads.
  • We only sell products we use ourselves.
  • We declare every ingredient, and our labels follow current UK labelling rules.

Why we don’t buffer our magnesium

Many magnesium glycinate supplements are “buffered”: magnesium oxide is mixed in to push up the magnesium figure on the label. Our magnesium glycinate is pure magnesium bisglycinate, with no magnesium oxide added. Each capsule gives 55 mg of elemental magnesium, all of it from glycinate.
