FitnessGenes Partners with Zinzino to Bring Omega-3 Testing and Personalised Supplementation to Customers

FitnessGenes has partnered with Zinzino to give customers at-home omega-3 blood testing and personalised supplementation from a single provider — answering the near 68% of customers who rate omega-3 as their top supplement.

FitnessGenes Partners with Zinzino to Bring Omega-3 Testing and Personalised Supplementation to Customers

FitnessGenes are pleased to announce a new partnership with Zinzino, giving customers access to at-home omega-3 blood testing and personalised supplementation through a single provider.

The partnership responds directly to customer demand. In recent FitnessGenes customer data, just under 68% rated omega-3 as their top supplement for optimising health and longevity - making it the most highly rated supplement across the entire customer base.

That interest is well founded. Research using the Omega-3 Index - a measure of EPA and DHA as a percentage of red blood cell fatty acids - has found it to be a strong predictor of all-cause mortality, with some studies suggesting its predictive power is comparable to that of smoking status. Despite this, most people have never had their Omega-3 levels measured, and dietary intake alone is a poor guide to what's actually circulating in the body.

Zinzino BalanceTest kit

Through the partnership, FitnessGenes customers can now order a Zinzino omega-3 blood test directly from FitnessGenes' website. The test measures 11 fatty acids, returning both an Omega-3 Index and an omega-6:3 ratio. Customers can then use Zinzino's BalanceOil to correct their levels, with follow-up testing to confirm the change.

Dr Sam Decombel, CEO, FitnessGenes: "Omega-3 status is one of the few things in nutrition where you can measure a real biomarker, act on it, and then measure again to see whether it worked. That closed loop is exactly what we look for in a partner, and it's why this fit was obvious."

Dr Decombel and Zinzino's Julia O'Dwyer will also feature in an upcoming episode of The FitnessGenes Podcast, breaking down what the Omega-6:3 ratio and Omega-3 Index actually mean, and what the evidence does and doesn't support.

Available now. Omega-3 blood tests can be ordered through FitnessGenes at fitnessgenes.com/shop. The first 15 customers to order will receive a complimentary bottle of BalanceOil.
