Vitamin D Boosted Energy & Focus - My Recovery Story


I usually run away when I see something with "Naturopathic" written on it. Years ago, I had blood work done and it showed my vitamin D level was low (16, should have been over 50). I went to the health food store and found these. I took them for a while and my energy level improved. Flash forward to recently, I hadn't been taking them for a while. I don't get outside much and even when I do, I have low Vit D levels. About a week ago I started taking these again. I've been having severe fatigue, body aches, and issues with my memory for many months. I'm a student and couldn't focus on my work. I can't say for 100% sure the two are linked, but I'm pretty confident that these helped me. I'm suddenly feeling a lot better and can focus again. The only thing is I wish these were vegan. If you're having these symptoms, it doesn't hurt to try it. They're usually about $10-15 at a HFS.


Vitamin Basics & Tips


Vitamin D plays a crucial role beyond bone health, influencing energy production, immune function, and cognitive performance. The reviewer's level of 16 ng/mL falls in the severe deficiency range (normal being 30-100 ng/mL), explaining symptoms like fatigue and memory issues. This fat-soluble vitamin is unique as it can be synthesized through sun exposure (specifically UVB rays), yet modern indoor lifestyles and sunscreen use contribute to widespread deficiency.


Dietary sources like fatty fish and fortified foods often prove insufficient, making supplementation necessary for many. The body stores vitamin D for weeks, explaining why symptoms reappeared after discontinued use. Memory and focus improvements align with recent studies showing vitamin D's neuroprotective effects and role in neurotransmitter synthesis. While the review mentions non-vegan capsules (likely containing gelatin), vegan options like lichen-derived D3 exist. Regular blood tests are recommended, as excessive supplementation can cause toxicity.


Optimal absorption occurs when taken with meals containing fats. Those with malabsorption issues or darker skin (melanin reduces UVB penetration) require particular attention to levels. Emerging research connects adequate vitamin D to reduced inflammation and improved muscle function, potentially explaining the reviewer's reduced body aches.
