Re: Shelf Registration
Statement on Form S-3

Ladies and Gentlemen:

This opinion is being furnished
to you in connection with the Registration Statement on Form S-3 (the “Registration Statement”), including the base prospectus
that is part of the Registration Statement (the “Prospectus”) and the sales agreement prospectus that is part of the Registration
Statement (the “ATM Prospectus”), filed by Synergy CHC Corp., a Nevada corporation (the “Company”), with the Securities
and Exchange Commission (the “Commission”) on November 26, 2025, 2025 under the Securities Act of 1933, as amended (the “Securities
Act”).

The Prospectus provides
that it will be supplemented in the future by one or more prospectus supplements (each, a “Prospectus Supplement”). The
Prospectus, as supplemented by the various Prospectus Supplements, will provide for the issuance and sale by the Company from time
to time of up to $100,000,000 aggregate offering price of (i) shares of the Company’s common stock, par value $0.00001 per
share (the “Common Stock”), (ii) shares of the Company’s preferred stock, par value $0.00001 per share (the
“Preferred Stock”), in one or more series or classes, (iii) warrants to purchase shares of Common Stock or Preferred
Stock (the “Warrants”), (iv) the Company’s senior debt securities and subordinated debt securities (collectively,
the “Debt Securities”), which may be issued pursuant to a senior debt indenture (the “Senior Debt
Indenture”) between the Company and the trustee to be named therein (the “Senior Debt Trustee”) and a subordinated
debt indenture (the “Subordinated Debt Indenture,” and together with the Senior Debt Indenture, the
“Indentures”) between the Company and the trustee to be named therein (the “Subordinated Debt Trustee” and,
together with the Senior Debt Trustee, the “Trustees”), (v) subscription rights to purchase Common Stock or Debt
Securities (the “Subscription Rights”) or (vi) units composed of any of the foregoing (the “Units”). The
Common Stock, Preferred Stock, Warrants, Debt Securities, Subscription Rights and Units are collectively referred to herein as the
“Securities.” The Warrants may be issued pursuant to a warrant agreement (the “Warrant Agreement”) between
the Company and a bank or trust company as warrant agent. Any Preferred Stock may be exchangeable for and/or convertible into shares
of Common Stock or another series of Preferred Stock. Any Debt Securities may be exchangeable and/or convertible into shares of
Common Stock or Preferred Stock. The Units may be issued pursuant to a Unit Agreement (the “Unit Agreement”) between the
Company and a bank or trust company as unit agent. The Securities are being registered for offering and sale from time to
time pursuant to Rule 415 under the Securities Act.

The ATM Prospectus relates
to the sale by the Company of shares of common stock having an aggregate offering prices of up to $5,690,000 (the “ATM Shares”)
under a sales agreement dated as of November 26, 2025, 2025 by and between the Company and Roth Capital Partners, LLC and Bancroft Capital LLC
(the “Sales Agreement”).

accuracy and completeness of the information, representations and warranties contained in the instruments, documents, certificates and

parties to agreements or instruments relevant hereto other than the Company, that such parties had the requisite power and authority (corporate
or otherwise) to execute, deliver and perform such agreements or instruments, that such agreements or instruments have been duly authorized
by all requisite action (corporate or otherwise), executed and delivered by such parties and that such agreements or instruments are the
valid, binding and enforceable obligations of such parties. As to any facts material to the opinions expressed herein that were not independently
