The pH alkaline water is produced through a natural process of infusing spring water with ionic marine-based minerals.
It is produced by Alka Power, which was founded by Steve Pettaros in 2012 and employs nine people in Mittagong in New South Wales southern highlands, turning over around $1 million a year.
The alkaline water is stocked in Woolworths and Harris Farm and Mr Evans promotes the water on social media, receiving royalties from sales of his brand.
«Pete has always been an advocate of the alkaline space and it just so happens he has always been interested and we said ‘If you want, do your own brand’,» said Mr Pettaros.
The Advertising Standards Community Panel received complaints about advertising on Alka Power’s website in particular to claims made about the PH of the water and its ability to remedy the medical problem of acidosis.
«The site, advertising a line of products, makes a lot of false claims, not just about the product but also about health and claims to treat a medical condition,» one complainant said.
Alka Power fought back against the complaints.
«Yet again we have been targeted by envious people, that have hidden agendas,» the business said in its response to Advertising Standards.
«This is the second time that Ad Standards have challenged our product and our integrity.»
However Advertising Standards found claims made by Alka Power on its website that the product will deactivate a peptide secreted in the stomach called pepsin, increase bone density and that sugar is one of the most acidic foods were all incorrect.
It upheld the complaint on the basis of a breach of section 2.1 of the AANA Food and Beverages Advertising and Marketing Communications code which deals with misleading and deceptive claims.
«The panel considered that the advertisement did depict material which was not truthful and was misleading with regards to the advertised product’s effect on the body,» it found.
Alka Power agreed to remove the claims identified by Advertising Standards from its website.
Mr Pettaros said he believed the complaint was from a «disgruntled competitor».
«We are a family business and we have been trolled terribly and we have had such horrendous things happen to our business,» he said. «When you get into Woolworths and other people are trying to get into Woolworths, they try to do anything they can to discredit us.»
Mr Evans directed requests for comment to Alka Power.
