Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	USANA Health Sciences, Inc. and subsidiaries ("the Company") is a global nutrition, personal health and wellness company that develops and manufactures high quality, science-based nutritional and personal care products. For financial reporting purposes, we categorize our operations into two reportable segments: direct selling and Hiya direct-to-consumer, with the remaining operating segments that are not currently material reported collectively as "Other" in our segment information. On December 23, 2024, the Company entered into a merger agreement with Hiya Health Products, LLC ("Hiya"), a leading direct-to-consumer provider of high-quality children's health and wellness products, by which the Company acquired a 78.85% controlling ownership interest. Refer to Note B - Business Combinations for further discussion. The Company's direct selling operations are grouped and presented in two geographic regions: (1) Asia Pacific, and (2) Americas and Europe. Asia Pacific is further divided into three sub-regions: (i) Greater China, (ii) Southeast Asia Pacific, and (iii) North Asia. Asia Pacific (1)Asia Pacific is organized into three sub-regions: Greater China, Southeast Asia Pacific, and North Asia. Markets included in each of these sub-regions are as follows: (i)Greater China – Hong Kong, Taiwan, and China. Our business in China is conducted by BabyCare, the Company’s wholly owned subsidiary. (ii)Southeast Asia Pacific – Australia, New Zealand, Singapore, Malaysia, the Philippines, Thailand, Indonesia and India. (iii)North Asia – Japan and South Korea. Americas and Europe (2)Americas and Europe – United States, Canada, Mexico, Colombia, and Europe (the United Kingdom, France, Germany, Spain, Italy, Romania, Belgium, and the Netherlands).
Consolidation	The Condensed Consolidated Balance Sheet as of December 28, 2024, derived from audited consolidated financial statements, and the unaudited interim condensed consolidated financial information of the Company have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the SEC. Accordingly, certain information and disclosures that are normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations.
Use of Estimates	The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. In the opinion of the Company’s management, the accompanying unaudited interim condensed consolidated financial information contains all adjustments, consisting only of normal recurring adjustments, that are necessary to state fairly the Company’s financial position as of June 28, 2025, and results of operations and cash flows for the three and six months ended June 28, 2025 and June 29, 2024.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard is intended to benefit investors by providing more detailed income tax disclosures. ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating the impact adoption of the standard will have on its consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-04): Expense Disaggregation Disclosures. The standard is intended to provide investors with more decision-useful information about a public business entity's expenses by improving disclosures on income statement expenses through disclosure of disaggregated information about specific natural expense categories underlying certain relevant income statement expense line items that include one or more of five natural expense categories. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating the impact that adoption of the standard will have on its consolidated financial statements. No other recent accounting pronouncements had, or are expected to have, a material impact on the Company's consolidated financial statements.
