Score 65.0

This stress support supplement provides a robust B-vitamin complex and a decent dose of L-Theanine for mood and focus. However, the primary adaptogen, Ashwagandha, is significantly underdosed for clinical efficacy, and proprietary blends reduce transparency.

Analysis

Zoi Research's Stress Support is designed as a broad-spectrum supplement addressing numerous health goals, primarily focusing on stress, mood, and cognitive function. It contains a comprehensive profile of B vitamins, including bioavailable forms like Methylcobalamin B12 and Zinc Picolinate, which are well-regarded by nutritionists for their roles in energy metabolism and overall cellular health. The inclusion of L-Theanine at 100mg provides a beneficial dose for promoting relaxation and mental focus, a common positive noted in online reviews for similar products. However, a significant drawback is the very low dosage of Ashwagandha (50mg root & leaf extract), which is far below the typically effective clinical dosages (e.g., 300-600mg of KSM-66 or Sensoril extract) cited in research and by health experts for meaningful stress reduction. Furthermore, the presence of 'Proprietary Absorption Blend' and 'Proprietary Stress Blend' without specifying ingredient quantities prevents consumers from fully assessing the efficacy and value of the undisclosed components, a practice often criticized online for lack of transparency.
Pros
  • Contains a comprehensive array of B vitamins in good dosages and generally well-absorbed forms (e.g., Methylcobalamin B12, Zinc Picolinate).
  • Includes L-Theanine, known for its calming and focus-enhancing effects, at a beneficial dose.
  • Relatively affordable price per serving for a multi-ingredient product.
Cons
  • The dose of Ashwagandha (50mg) is significantly lower than typically recommended for effective stress support by nutritionists and research.
  • Reliance on 'Proprietary Blends' (Absorption Blend, Stress Blend) lacks transparency regarding the exact amounts of other beneficial compounds.
  • The wide array of claimed goals makes it challenging for the product to excel in all areas with the given ingredient profile and dosages, potentially diluting its impact.
Warnings
  • Individuals sensitive to high doses of B vitamins should consult a healthcare professional, especially with the potent levels present.
  • The low dose of Ashwagandha might not provide the expected stress relief for users seeking significant adaptogenic effects.

Report overview

Categories

The product delivers an excellent dose of 250mg of Pantothenic Acid (Calcium D-Pantothenate). Vitamin B5 is crucial for adrenal function, stress response, and energy metabolism, making this a standout component for stress support and energy production, often recommended by nutritionists for adrenal health.
The product provides 100mcg of Vitamin B12 in the highly bioavailable Methylcobalamin form, which is superior to Cyanocobalamin in terms of absorption and utilization. This is an excellent choice for supporting energy, nerve function, and red blood cell formation.
With 25mg of Thiamine Hydrochloride, the product delivers a robust dose of Vitamin B1. Thiamine is crucial for carbohydrate metabolism and nerve function, and this amount effectively supports these processes for energy and neurological health.

Goals

The product contains a full spectrum of B vitamins in strong doses, which are essential cofactors for cellular energy production and metabolism. These adequate levels directly support energy maintenance and help prevent fatigue associated with B vitamin deficiencies, a common benefit cited by nutritionists.
All included B vitamins are fundamental coenzymes in various metabolic pathways, including carbohydrate, fat, and protein metabolism. The high doses ensure ample support for these crucial metabolic processes, making this product effective for boosting metabolic function, consistent with nutritionist recommendations.
B vitamins, particularly B6, B12, and Folate, are crucial for neurotransmitter synthesis and homocysteine metabolism, which are vital for cognitive function and protecting brain health. Choline also plays a role in acetylcholine production, supporting memory and brain signaling, as supported by scientific literature.
