Frequently Asked Questions
1. What is Ca-AKG?
Calcium Alpha-Ketoglutarate (Ca-AKG) is a calcium-bound form of alpha-ketoglutarate — a key intermediate in the Krebs cycle, the body’s central energy-producing pathway. AKG levels naturally decline with age, which has made it an area of growing interest in longevity research.
Optima Max Ca-AKG uses a calcium-complexed form to improve bioavailability and residence time in the digestive tract compared to uncomplexed AKG. Research has linked Ca-AKG to epigenome support, reduced inflammaging and improved mitochondrial efficiency — making it a complementary addition to a science-led longevity routine.

2. Who is it for?
Ca-AKG is suited to:
- Individuals looking to support cellular energy and mitochondrial function.
- Those interested in epigenome support and healthy ageing pathways.
- People following metabolic optimisation or fasting protocols.
- Anyone seeking to address age-related decline in Krebs cycle intermediates.
- Those complementing NAD+, spermidine or other longevity regimens.
3. Can I take it with other supplements?
Yes — Ca-AKG is commonly stacked within longevity protocols and pairs particularly well with NAD+ molecules and other cellular renewal actives.
Pairs particularly well with:
Pairs particularly well with:
- Enhanced Optima Max (NAD+) and Neuro Optimiser (NR) — together with Ca-AKG, these form the textbook longevity stack: Krebs cycle support plus direct NAD+ precursors for cellular energy.
- Spermidine — supports autophagy and cellular renewal, complementing Ca-AKG’s role in epigenome and mitochondrial support.
- Berberine — supports glucose metabolism and AMPK activation, a natural pairing for those following metabolic optimisation or fasting protocols.
- GlyNAC — provides antioxidant and mitochondrial support, reinforcing Ca-AKG’s cellular energy benefits.
4. How does it combine with NAD+?
Ca-AKG and NAD+ are two of the most-researched longevity molecules, and they support different but complementary cellular pathways — Ca-AKG replenishes a key Krebs cycle intermediate and supports the epigenome, while NAD+ supports cellular energy and metabolic function.
For a full inside-out approach to cellular health, Ca-AKG pairs beautifully with our topical Active NAD+ Face Serum and Active NAD+ Essential Cream — addressing cellular energy from within while supporting skin health at the surface.

5. When will I see results?
Ca-AKG’s benefits are associated with long-term cellular and metabolic processes rather than immediate effects. Consistent daily use is recommended as part of a structured longevity routine.
