Niacin 30 mg
Thiamin 185 mg
Score 25.0
RoxyLean uses a proprietary blend, severely limiting transparency regarding its active ingredients for energy and metabolism. It contains an extremely high, likely unnecessary dose of Thiamin and a low dose of Niacin, making its broad health claims questionable. The lack of ingredient transparency and questionable dosing makes it a less desirable option.

RoxyLean uses a proprietary blend, severely limiting transparency regarding its active ingredients for energy and metabolism. It contains an extremely high, likely unnecessary dose of Thiamin and a low dose of Niacin, making its broad health claims questionable. The lack of ingredient transparency and questionable dosing makes it a less desirable option.
RoxyLean by BPI Sports is marketed with a broad range of goals, including energy, metabolism boost, heart, skin, brain, cognitive, and cardiovascular health, along with testosterone support. Its listed ingredients are a proprietary blend, Niacin (nicotinic acid), and two forms of Thiamin. The proprietary blend (510mg) is a significant concern as it prevents consumers from knowing the precise dosages of ingredients that are likely responsible for its energy and metabolism claims, often implying the presence of undisclosed stimulants. The Niacin content at 30mg is in the nicotinic acid form, which can cause the 'niacin flush' and is a relatively low dose for substantial heart health benefits, which typically require much higher, medically supervised doses. The Thiamin content, totaling 370mg, is exceptionally high compared to the recommended daily allowance, far exceeding what is generally needed for metabolic or neurological support, and its efficacy at such an extreme dose for general purposes is questionable. Online reviews frequently mention an energy boost but also report common stimulant-related side effects such as jitters, making the proprietary blend a potential source of concern. Nutritionists often advise against proprietary blends due to transparency issues and the potential for unoptimized ingredient ratios or hidden high stimulant content.
- Contains B vitamins (Niacin and Thiamin) which are essential for basic metabolic functions and energy production.
- May provide an energy boost, as often reported in user reviews, likely due to undisclosed stimulants within the proprietary blend.
- The use of a proprietary blend prevents full disclosure of active ingredient dosages, making it impossible to evaluate efficacy and potential risks of all components.
- The Thiamin dosage (370mg total) is excessively high and far beyond physiological requirements for general health, raising concerns about formulation rationale.
- The Niacin (nicotinic acid) at 30mg can cause an uncomfortable 'niacin flush' in some individuals, and the dose is insufficient for the cardiovascular benefits often associated with higher therapeutic niacin doses.
- Claims for 'Testosterone Support' are not directly supported by the disclosed ingredients (Niacin, Thiamin).
- The proprietary blend may contain undisclosed stimulants, which could lead to side effects such as jitters, increased heart rate, anxiety, or sleep disturbances, especially in sensitive individuals.
- The unusually high Thiamin dosage, while generally considered safe due to water-solubility, is not physiologically justified for general supplementation and indicates a potentially poorly formulated product.
- Individuals sensitive to Niacin may experience flushing, itching, or redness, even at this relatively low dose of nicotinic acid.

Categories
Niacin 30.0
The product contains Niacin in the form of nicotinic acid at 30mg. While this is an essential B vitamin, the dose is relatively modest and can cause the 'niacin flush,' which is often undesirable for general supplementation. Many alternative Niacin products offer higher doses, 'no-flush' forms (like inositol hexanicotinate or niacinamide), or better value, making RoxyLean a less competitive option solely for its Niacin content.
Thiamin 20.0
RoxyLean contains an extremely high dose of Thiamin (totaling 370mg), far exceeding the Recommended Daily Allowance (RDA). While Thiamin is crucial for energy metabolism, such a high dose is generally unnecessary for healthy individuals and does not confer additional benefits over appropriately dosed supplements. This excessive amount suggests a suboptimal formulation and offers poor value when compared to alternative Thiamin or B-complex supplements that provide physiologically relevant doses.
Goals
Energy 40.0
B vitamins are crucial for energy metabolism, so the presence of Niacin and Thiamin provides a foundational element for energy support. However, the proprietary blend likely contains stimulants that contribute to the perceived 'energy' boost, but the lack of transparency about these ingredients raises concerns about dosage, potential overstimulation, and associated side effects like jitters or crashes. A balanced B-complex would offer safer, more sustainable energy support from B vitamins.
Metabolism Boost 40.0
Niacin and Thiamin are vital coenzymes in various metabolic processes, thus theoretically supporting metabolism. However, the proprietary blend is likely intended to provide a more direct 'boost' through thermogenic or stimulant effects, without disclosing the specific ingredients or their quantities. This lack of transparency and the inclusion of unnecessary excessive Thiamin make it a less ideal and potentially risky choice compared to transparent metabolic support supplements.
Brain Health 25.0
Thiamin plays a crucial role in neurological function and neurotransmitter synthesis, and B vitamins generally support brain health. However, the extremely high dose of 370mg Thiamin is far beyond what is needed for optimal brain health in healthy individuals and offers no proven additional cognitive benefits compared to adequate dosing. The proprietary blend's impact on brain health is unknown, potentially introducing undisclosed stimulants that could cause undesirable neurological side effects.
