@jamezb46 said in Need To Figure Out Niacin and NAC Curing Me:
Can you link to any studies showing that 500-600mg Niacinamide daily caused any insulin resistance?
I'm not going to make this search for 3 reasons:
Need time and much energy.
The excerpts from the study given by Amazoniac have already given 2 sources on excess B3. You could have been first trying to reach them.
Note that the excess B3 must be understood on the long term, not in cure.
The studies are not all clear (different conclusions).
B3 supplement has an impact on lipogenesis. The time period impact is said to be only for 2 hours. I don't feel it so (I took Kg / Lb weight when taking niacinamide 100 mg).
Niacin and niacinamide are said to affect lipolysis differently. In theory.
Examples of studies:
*) From “Long-term Treatment With Nicotinamide Induces Glucose Intolerance and Skeletal Muscle Lipotoxicity” p4
https://raypeatforum.com/community/threads/long-term-treatment-with-nicotinamide-induces-glucose-intolerance-and-skeletal-muscle-lipotoxicity.15393/post-211103
=> It is shown that nicotinamide and oxythiamine inhibit inclusion of C from glucose into free fatty acids, antivitamin intensifies lipolysis in the fatty tissue of the diseased animals."

NB: Possible adverse effect when taking B3 longer than 1 month.

Conclusion: The appetite-stimulating effect of nicotinamide appears to involve oxidative stress. Excess niacin consumption may be a major factor in the increased obesity prevalence in US children.
=> A 3-h blood glucose was significantly lower after co-administration of glucose and 300 mg nicotinamide. The obesity prevalence among American children increased with the increasing per capita niacin consumption, the increasing grain contribution to niacin due to niacin-fortification, and the increasing niacin-fortified ready-to-eat cereal consumption, with a 10-year lag. The regression analyses showed that the obesity prevalence in the US children of all age groups was determined by niacin consumption.

Conclusion: These findings suggest that nicotinamide overload, which induced an increase in plasma N(1)-methylnicotinamide, associated with oxidative stress and insulin resistance, plays a role in type 2 diabetes.
=> Results: Diabetic subjects had significantly higher plasma N(1)-methylnicotinamide levels 5 h after a 100-mg nicotinamide load than the non-diabetic subjects.
Decrease in NAD/NADH ratio and increase in H(2)O(2) generation were also observed in human erythrocytes after exposure to N(1)-methylnicotinamide in vitro.
Note (LucH): increase in H(2)O(2) = Hydrogen peroxide => ROS = oxidative stress.
