Physic Ventures, a San Francisco venture firm that invests in companies focused on healthcare and sustainable living for consumers, has finished raising its first fund of $159 million.

So far, Physic has put money into five companies, including sleep-inducing chocolate maker Dreamerz Food, the interactive exercise company Expresso Fitness and eco-friendly plastic producer Novomer.

Managing director Will Rosenzweig said that where traditional life science investors put money into things like drugs that are reimbursed by health-care providers, Physic will invest in products over which consumers have more decision power.

Physic started off in April 2007 with a $125 million commitment from consumer goods giant Uniliver, which was later reduced to take on investments from institutions, pension funds and strategic investors.

The firm seeks to exploit synergies between its strategic investors, like Unilever and healthcare giant Humana, and its various portfolio companies. Dreamerz Food products, for example, are carried in Pharmaca stores — another Physic investment.

Previous reports indicated that Physic had raised $190 million; Rosenzweig says the fund was oversubscribed to that amount, but the investment was cut back, and Unilever’s portion reduced to about half of the total.
