I recommend using NMN once every 4th or 5th cycle. That should keep cost under control while still giving you some of its benefits that I don’t believe come from nicotinamide.Thanks, I looked into the possibility of using NMN instead but I ditched it due to the cost of it (living in the EU makes it difficult to get supplements at acceptable prices)
I went back using D-Ribose but only 500mg instead of 1000 and take it during a meal. Everything is fine so far.
Regarding the protocol, I'm surprised no one discussed the risk of homocysteine increase while taking L-methionine, am I being too cautious in this regard ? Is it canceled out by some other supplement in the stack ?
Also, can you see if a good American NMN brand like Double Wood or Prohealth ship to the EU for a better price?
For homocysteine that should only be a problem if someone is taking the protocol more than once a month.
However, you make a good point because increased homocysteine is negatively correlated with cardiovascular health and longevity, and also because it is an mTor activator.
Homocysteine elevation might have been why Turnbuckle never eliminated his high blood pressure after years on the protocol.
As a precaution I would take serine with meals high in b vitamins to ensure any excess homocysteine generated by the protocol’s use of methionine is converted safely to cystathione and (best of all) glutathione, the body’s master antioxidant.
Use it a week before and a week after the C60 protocol just to make sure nothing about serine negatively reacts with rest of the protocol.
Without serine excess methionine keeps converting to homocysteine, and homocysteine converts back to methionine.
Serine breaks this logjam.
See these two videos by Longecity contributor Michael Lustargten (FYI Michael posts here on this forum under his own name) for how he reduced his homocysteine levels with serine.

However, I don’t believe Michael needed to supplement B6 with serine because B6 in supplement form has undesirable side effects.
It is safer to get B6 from foods high high in b vitamins like vitamin fortified cereals and meat, then take serine with that food.
Don’t supplement serine on an empty stomach because it can reduce blood sugar.
The bonus is that serine is associated with lower cancer risk and extended lifespan.

Serine and glycine have an important role in the folate-dependent one-carbon metabolism. No prior epidemiologic study has evaluated the associations for serum levels of serine and glycine with pancreatic cancer risk. We performed a nested case-control study of 129 incident pancreatic cancer cases and 258 individually matched controls within the Shanghai Cohort Study, a prospective cohort study involving 18,244 male residents in Shanghai, China. We found that the risk of pancreatic cancer was reduced by more than 70% in individuals with elevated levels of serine and glycine in serum collected, on average, more than 10 years prior to cancer diagnosis. These novel findings support a protective role of serine and glycine against the development of pancreatic cancer in humans that might have an implication for pancreatic cancer prevention.

Purpose of Review
Ogimi village is renowned for its aging population. We sought to determine if the l-serine content of their diet could account for their neurological health.
Recent Findings
The most frequently consumed food items, including tofu and seaweeds, are rich in the dietary amino acid l-serine. l-serine content of the Ogimi diet >8 grams/day for Ogimi women significantly exceeds the average American dietary intake of 2.5 grams/day for women >70 years old.
Summary
Our hypothesis that the high l-serine content of the Ogimi diet is related to the paucity of tangle diseases among villagers is buttressed by in vivo results with non-human primates where dietary l-serine slowed development of neurofibrillary tangles and β-amyloid plaques by up to 85% and a human clinical trial finding that l-serine at 15 grams/day twice daily slows functional decline in ALS patients. Analysis of the Ogimi diet suggests that l-serine should be evaluated for therapeutic potential as a neuroprotective agent.
