ORDER DENYING TRANSFER
JOHN G. HEYBURN II, Chairman.Before the Panel: * Pursuant to 28 U.S.C. § 1407, defendant USPlabs, LLC, moves to centralize this litigation, which consists of nine actions pending in six districts as listed on Schedule A, in the Eastern District of Pennsylvania or, alternatively, the Western District of Texas.1 The actions in this litigation concern US-Plabs’ dietary supplements sold under the brand names “OxyElite Pro” and “Jaek3d,” and consist of both individual personal injury actions and false advertising class actions with respect to both the original and reformulated versions of the products.2
*1341The parties’ positions with respect to centralization vary widely. Ten co-defendants3 and plaintiffs in the Payne action support the motion. Plaintiffs in six actions on the motion (Mazzeo, Ogbanna, Reed, Sparling, Van Howten, and Waikiki) and four potential tag-along actions oppose centralizing all nine actions, but support some combination of separate MDLs: (1) personal injury actions concerning OxyElite Pro and Jack3d products formulated with DMAA; (2) personal injury actions concerning OxyElite Pro formulated with aegeline; and/or (3) a separate MDL for the false advertising actions. Plaintiffs in the Battuello and Campos actions and defendant Natural Alternatives International, Inc., oppose centralization in any form.
Defendants contend that centralization of all actions is warranted, notwithstanding differences in the primary active ingredient and the claims presented by the tort and false advertising actions, because all actions allege that the OxyElite Pro and Jack3d product lines are unsafe and rely on the same series of FDA actions to support their claims. Defendants anticipate that actions alleging injury from Ox-yElite Pro with aegeline will seek discovery concerning the DMAA products as relevant background and, thus, discovery and pretrial motions likely will overlap. In response, plaintiffs in all the pending personal injury actions contend that the DMAA and aegeline formulations are so dissimilar that they are akin to different drugs, referring to the distinct scientific studies, labels, regulatory histories, and injuries associated with DMAA and aege-line. Additionally, plaintiffs in two of the three false advertising actions represent that they will not delve into the medical issues raised by the personal injury actions, and instead will focus on whether USPlabs’ advertising was likely to mislead and deceive consumers.
On the basis of the papers filed and the hearing session held, we will deny US-Plabs’ motion. Although all actions allege that various USPlabs products are unsafe, the Panel is not persuaded that Section 1407 centralization is necessary either to assure the convenience of the parties and witnesses or for the just and efficient conduct of this litigation. On the present record, it appears that the different formulations of the products will not give rise to substantially overlapping discovery, particularly in light of the differences in the health risks alleged and the distinct regulatory responses to the DMAA and aegeline products. Additionally, the three consumer class actions raise a unique threshold issue with respect to the alleged impact of a state court class settlement agreement reached in 2012.
The Panel also declines plaintiffs’ invitation to establish three separate MDLs to compensate for the differences in the actions. There are a limited number of actions and involved counsel, with two groups of plaintiffs’ counsel already coordinating most of the personal injury actions. *1342At oral argument, plaintiffs’ counsel in three of the actions concerning DMAA indicated that the number of such actions would remain small since USPlabs’ inventory of DMAA products was destroyed in 2012. Additionally, the record indicates that the actions alleging injury from aege-line already are being coordinated in the District of Hawaii.
In the present circumstances, voluntary coordination among the parties and the involved judges is preferable to centralization. We encourage the parties to employ various alternatives to transfer which may minimize the potential for duplicative discovery and/or inconsistent pretrial rulings. See, e.g., In re: Yellow Brass Plumbing Component Prods. Liability Litig., 844 F.Supp.2d 1377, 1378 (J.P.M.L.2012); see also Manual for Complex Litigation, Fourth, § 20.14 (2004).
IT IS THEREFORE ORDERED that the motion, pursuant to 28 U.S.C. § 1407, for centralization of these actions is denied.

Judges Marjorie O. Rendell and Lewis A. Kap-lan look no part in the decision of this matter.
. The Panel has been notified of nine’ additional related actions.
. The original versions of OxyElite Pro and *1341Jack3d contained 1, 3 dimethylamylamine ("DMAA”), which is allegedly a stimulant. Jack3d also included an ingredient called CarnoSyn that allegedly enhanced the effects of DMAA. The reformulated version of OxyElite Pro contained N-[2-hydroxy-2(4-methoxy-phenyl) ethyl]-3-phenyl-2-propenamide ("aegeline”). The versions of the products at issue at issue are no longer on the market following various actions by the U.S. Food and Drug Administration ("FDA”) and discontinuation of the products in 2012 and 2013.
