The US Market
The United States has the world's largest hangover supplement market. Products are sold as dietary supplements under FDA's DSHEA framework — they cannot make disease claims but can be marketed as supporting normal body functions. This regulatory environment means quality varies enormously.
Red Flags in the US Market
Proprietary blends are particularly common in the US market — products that list ingredients without disclosing amounts. This allows brands to include DHM at 10mg while still marketing as a "DHM formula." Look for products with fully disclosed ingredient amounts.
Be skeptical of celebrity endorsements and massive marketing budgets — these are costs that come out of the formula budget. The best-formulated products are often not the most heavily advertised ones.
What to Buy in the USA
Look for: DHM 300mg per dose, milk thistle (standardised silymarin extract) 150-200mg, full B complex with disclosed amounts, L-theanine 50mg+. Any supplement meeting these criteria at a reasonable price point is worth trying — the 30-day guarantee on Revive means you can evaluate it on your own nights out with zero financial risk.
