The 4-Part Morning Longevity Stack: NMN, TMG, AKG, and Vitamin C

As we age, our cellular "fuel tank" begins to empty. This is not a theoretical decline; it is a measurable drop in NAD+ (Nicotinamide adenine dinucleotide), a vital coenzyme required for every energetic process in our body—from repairing DNA to firing neurons. By age 70, NAD+ levels can drop by more than 50% compared to our youth. To combat this, many are turning to a specific synergistic morning protocol.

The Engine and the Oil: NMN and TMG

NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+. Taking 500mg upon rising helps rev the mitochondrial engine, providing the raw material needed for cellular repair and energy metabolism. However, NMN requires a partner to work safely and effectively.

TMG (Trimethylglycine) acts as a "methyl donor." When the body processes NMN into NAD+, it consumes methyl groups. Supplementing with 750mg of TMG ensures these reserves aren't depleted, maintaining a healthy balance for liver function and cardiovascular health by regulating homocysteine levels.

Optimizing the Krebs Cycle with AKG

Alpha-Ketoglutarate (AKG) is a key molecule in the Krebs cycle—the process that generates nearly all cellular energy. Levels of AKG decline precipitously as we age, but supplementation has shown remarkable promise in longevity science.

Key Benefits of AKG:

The Protective Shield: Calcium Ascorbate

A morning stack is only as good as its stability. Calcium Ascorbate is a non-acidic, buffered form of Vitamin C. It serves as an antioxidant shield, neutralizing free radicals that may be generated as cellular metabolism increases. Furthermore, it supports collagen synthesis for joint and arterial health.
