Nutrient quality

94 Highest impact

Inclusion of bioavailable selenomethionine and chromium picolinate provides strong foundational support for thyroid and glucose metabolism. While core minerals are well-represented, the reliance on a proprietary blend obscures the specific potency of individual botanical actives.

Ingredient transparency

79 High impact

Labeling clearly states milligram and microgram doses for the primary minerals and B6. However, the use of a proprietary complex for the majority of the formula's active weight limits full transparency regarding individual ingredient dosages.

Customer satisfaction

Solid average ratings and a healthy review count indicate significant user approval for sleep quality and metabolic goals. Feedback consistently highlights the non-stimulant nature as a primary benefit for nighttime use.

Value for money

86 Highest impact

Competitive pricing per serving for a specialized metabolic and sleep support formula. Meaningful mineral doses and high user acceptance provide solid overall value for nighttime supplementation.
