Two important side effects that everyone should know and that I found out about the hard way:
1) Maximizes iron absorption: Fine if you are taking this with non-heme iron food sources (plant food) but if you take this with a lot of animal food sources, you will increase your iron absorption a lot. For women, it's not a huge risk before menopause but for post-menopausal women and most men, increased iron intake increases the risk of heart attacks.
2) Potent liver damage multiplier: Vitamin C may not damage the liver directly but when taken in excess, it WILL magnify the damage to the liver caused by any other hepatotoxin, such as alcohol.
Anything over the recommended amount and depends on the condition of your liver and what you are taking with vitamin C. If you are consuming something that is likely to hurt your liver (fast food fried with low quality oil) and also take vitamin C tablet with that, you won't be doing your liver any favors. In such a case, I would prefer to have orange, grapefruit or lemon juice rather than a vitamin C tablet because at least that way, it's natural and nature usually doesn't oversupply nutrients to the point of causing harm to us.What is considered excessive vitC? Anything over 2000mg? 3000, 5000?
The Relationship between Fatty Acids and Different Depression-Related Brain Regions, and Their Potential Role as Biomarkers of Response to Antidepressants - PMC (nih.gov)I supplement because I'm trying to restore brain neurotransmitters f'd up from lack of sleep due to some internal injury of the neck.
Consistent with the notion that dietary fats can influence brain lipid composition, the long-term (11 weeks) consumption of a MUFA-enriched diet (fat from olive oil) significantly increased total MUFA levels in the mouse brain and concomitantly reduced SFA levels . Notably, a high MUFA:SFA ratio has been shown to increase brain membrane fluidity , which can facilitate neurotransmitter signal transduction and improve mental health.
Why am I not surprised. Rendering an old person unable to function is a great final payday for the "industry of medicine" and for "planet savers" to cull the herd. "Aged care" facility and the wheelchair industry got stimulus money.Supplements: Man unable to walk after taking popular supplement to correct deficiency - Today News Post
That's why I'm wary of most multivitamins since they contain way more B-vitamins than required.
Calcium supplementation is counterproductive without K2 activating the proper enyzmes to deposit calcium where the body wants it(bones/teeth) and not in unwanted places like the arteries. .Solgar's Vitamin D/Calcium formulation was ultra effective at increasing the calcium level in my blood. So much that I got extremely high blood pressure (couldn't even remember the password to my PC that I used everyday). That was my last ever Solgar supplement.
The Solgar one did have K2 but the formula was so good that it maximized Calcium absorption at such a rate that my body didn't even have time to utilize it. Good for old people may be but even then, under a doctor's supervision with regular tests to ensure they don't get a stroke or heart attack from calcification.Calcium supplementation is counterproductive without K2 activating the proper enyzmes to deposit calcium where the body wants it(bones/teeth) and not in unwanted places like the arteries. .
