Capstone Financial Group Inc. has agreed to invest $57 million in Twinlab Consolidation Corp.

The investment will be made through a private offering over the course of three years. The transaction will result in Capstone owning about 38 percent of Twinlab.

For Twinlab, the agreement will allow it to make acquisitions in the health and wellness space.

Capstone had already agreed, in January, to raise $130 million in financing for Twinlab Corp., which makes nutritional supplements.

Irvine, California-based Capstone is a holding company that picks up stakes in other companies, and then works with management to increase earnings. The company is publicly traded on the over-the-counter exchange. The company, in February, agreed to buy an independent broker-dealer.

Other nutritional supplement transactions include Helen of Troy Ltd.’s purchase of Healthy Directions LLC, and Argos Soditic’s deal for Natural Distribution Group in April.
