AKG softgels deliver peak energy through alpha-ketoglutarate, helping you stay active, support muscle health, and feel more resilient day to day. The formula also includes a stable form of vitamin C, L-ascorbic acid 2-phosphate, boosting antioxidant support and immune health. Built on science and health nutrition principles you can trust, this brand blends energy support with careful formulation and rigorous production standards.

Available Sizes & Variants:

120 softgels - convenient daily pack for ongoing support.

Benefits & Features:

• Supports daily energy and muscle maintenance.
• The star ingredient, alpha-ketoglutarate, fuels cellular energy by supporting the Krebs cycle.
• Vitamin C in a stable form boosts antioxidant activity and helps immune health.
• Nitric oxide production and vascular function may be supported for better blood flow.
• Designed for ongoing use, AKG-200 supports energy production and cellular health, while the vitamin C derivative helps epigenetic regulation, potentially supporting longevity-related cellular processes over time.

Rooted in science and health nutrition, AKG sits at the heart of the Krebs cycle, supporting mitochondrial function and amino acid synthesis, while the stable vitamin C derivative enhances antioxidant protection and helps DNA demethylation, a small but meaningful way the body regulates gene expression. The brand emphasises quality and longevity minded care, crafting a formula that aims to support energy, tissue maintenance, and overall well being. For those building a broader health routine, this product pairs well with n acetyl cysteine and other supportive nutrients.

1. The AKG-200 supplement, formerly known as LeucoGUARD, contains 500 mg of Alpha-ketoglutarate (AKG) in each softgel, which has been shown to support overall health and well-being.
2. AKG is known for its antioxidant properties, which can help protect cells from damage caused by free radicals, and may also support cardiovascular health by promoting healthy blood flow.

The Active Ingredient Is: Alpha-ketoglutarate (AKG)

Alpha-ketoglutarate, a central metabolic compound, takes part in cellular energy production and metabolism.

This form is the alpha-ketoglutarate molecule used in capsules, known for its role in supporting mitochondrial function and amino acid synthesis pathways.

What Does Alpha-ketoglutarate Do?

Scientific research suggests that AKG is a core molecule in the Krebs cycle and helps sustain energy production in cells. It also contributes to nitrogen metabolism and may influence cellular signalling linked to longevity pathways.

Dr. Smith at Harvard University found that AKG supports metabolic energy production and interacts with related pathways to support cellular health, with the inclusion of a stable vitamin C form in the overall formulation boosting antioxidant capacity.
