Overview

The G.F.S.-2000 Capsules contain a wide array of ingredients, many of which have individual research-backed benefits. However, the use of proprietary blends, particularly the "Green Food Supplement Blend" and "Probiotic Culture Blend," makes it impossible to determine if clinically effective doses of most ingredients are present. While some components like Vitamin A are optimally dosed, others, such as Green Tea Extract, Milk Thistle, Ginkgo Biloba, Bilberry, and Grape Seed Extract, are significantly underdosed, which severely limits their potential health benefits. The probiotic blend also lacks specific CFU counts, making it difficult to assess effectiveness.

The Good

Diverse array of phytonutrients from various green foods, fruits, and vegetables.

Contains a beneficial range of probiotic strains, though specific CFUs are unknown.

Includes well-regarded antioxidant and anti-inflammatory extracts such as spirulina, chlorella, and green tea.

The Bad

Extensive use of proprietary blends (Green Food Supplement Blend, Probiotic Culture Blend) obscures individual ingredient dosages, making efficacy difficult to assess.

Many potent individual extracts (Green Tea Extract, Milk Thistle, Ginkgo Biloba, Bilberry, Grape Seed Extract) are significantly underdosed, likely rendering them ineffective.

The term "Blue Green Algae" in the blend without specifying the total amount or main species (like spirulina or chlorella) adds to opacity.
