From Amazon.com
Great multivitamin and I can feel the difference in energy when I take them.
I do want to add a side of caution however and i didn’t knock stars off for this because I know it is more to do with personal individual issue than the product itself. Still none the less worth mentioning.
While I love these vitamins cause they do work great. I’ve discovered that I’m not able to take them every day. They are likely to strong of a dose for me to do so, because after taking them everyday for a week I noticed was starting to have the side effect of mild stomach pain and general just feeling crummy.
I did try eating a meal before taking to see if that was the issue and it helped a small bit with the stomach pain but not completely.
So i switched to taking these every other 2-3 days and found that works better. I don’t feel ick when i do it this way and i think it’s due to maybe I just need longer to metabolize it.
My bf also takes these and he’s not had any issue with them when taking daily. He’s also loving the difference they’ve made in his overall energy/health.
Vitamin Basics & Tips
Understanding Vitamin A Supplementation
Vitamin A is a fat-soluble nutrient essential for vision, immune function, and cellular communication. The user's experience highlights individual variations in supplement metabolism. Some people process vitamins faster than others due to genetic factors, liver function, or body composition.
Dosage Considerations
The Recommended Dietary Allowance (RDA) for adult males is 900 mcg RAE and 700 mcg RAE for females. Many multivitamins contain 100-150% DV, which might explain the user's sensitivity. Fat-soluble vitamins accumulate in body tissues, making proper dosing crucial.
Managing Stomach Discomfort
Taking supplements with food helps absorption but doesn't eliminate all side effects. The user's solution of spacing doses aligns with clinical recommendations for sensitive individuals. Pairing with meals containing healthy fats (avocado, nuts) enhances absorption while reducing gastric irritation.
Individual Metabolic Differences
Genetic variations in the BCMO1 enzyme affect vitamin A conversion efficiency. Approximately 45% of people have reduced conversion capacity, potentially requiring adjusted dosing. The boyfriend's tolerance suggests efficient metabolism of preformed vitamin A (retinyl esters).
Synergy with Other Nutrients
Vitamin A works best with zinc and vitamin D. Zinc deficiency impairs vitamin A metabolism, while vitamin D helps regulate its absorption. Users experiencing side effects might benefit from checking zinc levels or adding a vitamin D supplement.
Natural Food Sources
Sweet potatoes (1400 mcg RAE per medium), spinach (570 mcg per ½ cup cooked), and eggs (75 mcg per large egg) provide natural vitamin A. Combining supplements with dietary sources requires monitoring to avoid exceeding safe limits (3000 mcg daily for adults).
Signs of Overconsumption
Mild symptoms include nausea and headaches. Chronic excess causes vision changes, bone pain, and liver damage. Users should consult healthcare providers if experiencing persistent symptoms, especially with existing medical conditions or medications.
Storage and Stability
Vitamin A degrades when exposed to light and heat. Store supplements in cool, dark places. Check expiration dates - oxidized vitamin A loses potency and may increase stomach irritation risks.
