<p>Hi this is a work in progress but it works to determine supplement efficacy for 500 conditions at the moment.<p>Things you can do:<p>- search for a condition -> find which supplements are effective -> see which studies indicate they are effective -> read individual study summaries<p>- search for a supplement -> see effectiveness table, dosing, safety, dietary sources, mechanisms of action (+ browse all original sources)<p>let me know what you think</p>

<p>Vitamin C’s relationship with cancer risk appears complex and context-dependent. While maintaining adequate blood levels (≥60.19 μmol/L) is associated with reduced cancer mortality, supplementation may increase postmenopausal breast cancer risk by 32% in women with already high dietary intake. This suggests a U-shaped relationship where both deficiency and excess may be detrimental, emphasizing the importance of personalized approaches to vitamin C intake.<p>See: <a href="https://inspectsupplement.com/vitamin-c/#Cancer" rel="nofollow">https://inspectsupplement.com/vitamin-c/#Cancer</a></p>

<p>Even though it is water soluble, yes it can accumulate, especially at the higher doses found in supplements. The primary way this happens is via unaware supplementation. Usually people are unaware that their product contains b6 - it's in a lot of products that are not advertised to contain it.<p>So even though it is water soluble it can still accumulate when taken at these high doses. Most supplements contain pyridoxine, which can acumulate and damage peripheral nerves. Indeed the form of B6 is important, and manufacturers take advantage of the fact that consumers (and medical practitioners) are unaware of the difference. Taking P-5-P may be less risky than pyridoxine hydrochloride, a cheaper option that is included in most supplements.</p>

<p>This makes sense when you consider the role that magnesium has in the body - it's involved in a lot of reactions, either directly or as a cofactor.<p>In fact, ATP exists typically as MG-ATP in the body.<p>Severe Deficiency is rare (or rarely diagnosed i should say) because the body maintains serum magnesium levels at the expense of skeletal mg.</p>
