Sisu

Sisu Vitamins is a Canadian supplement company. Derived from a Finnish word meaning “inner strength,” Sisu lives up to this meaning with their commitment to helping people find a balance between their bustling daily lives and health and well-being.

Every day, they strive to formulate supplements of the utmost efficacy and quality.

Sisu’s Brand History

Starting in 1980, Finnish founder, Harlan Lahti, first started selling his formulations at his pharmacy in Vancouver. With the vision to help people stay healthy longer and recover from illness quicker, Sisu Vitamins came to life.

Since its humble beginnings, Sisu has made a name for itself in the natural health industry by formulating patented products that are efficacious, bioavailable and high-quality and is now one of the fifth largest supplement brands in all of Canada.

In 1988 Sisu’s growth spiked when they brought what has become one of their most popular products to Canada, Ester C. At this time they were the sole distributor of this product.

Lastly, Sisu has always been devoted to education. They work hard to educate the natural health retailers that carry their products so no matter where Sisu customers are shopping, they’re getting knowledgeable, expert advice.

Sisu’s Core Values

Quality Control

Sisu Vitamins cares about quality and purity. That’s why they stick to Health Canada’s regulations when it comes to formulating, testing, labelling and marketing their products. All of their products are also third-party tested, this way you can trust that what’s on the label is what’s in the bottle.

They are also driven by innovation. This includes using nothing but clinically validated or patented ingredients. All of their products are also non-GMO and gluten-free.

Their signature packaging is made from pharmaceutical-grade, non-leaching glass that diminishes oxygen, moisture and light exposure, all of which can spoil your product if they get through the bottle.

Sisu formulas are guaranteed for their potency, purity and proven dosages to support your health needs.

Environmentally-Friendly Practices

Sisu cares about the environment and the planet. They’re industry-leaders when it comes to environmental awareness from ethical manufacturing to their recyclable glass blue bottles.

Beyond their packaging, they also follow environmentally friendly practices throughout their facilities by eliminating air shipping, using recycled paper packaging and being a part of local recycling programs for paper, plastics, metal and organics.
