A MORNING MIGRAINE SNUCK UP ON ME and took me by surprise. I took note of what was going on when my vision blurred with white out spots. A blind spot started and I couldn't see well. I call it a white out migraine.
I popped some OTC migraine medicine before a brilliant light show started. After a few minutes it appeared, but was short lived by taking the meds early. No upset stomach this go round, just fatigue and weakness.
Migraines can be a symptom of vitamin deficiencies.
Certain vitamin deficiencies, particularly in vitamins B12, D, riboflavin, and magnesium, have been linked to an increased frequency and severity of migraines.
🏥 Take the Calcium, Vitamin D3 and Vitamin K2 tablet or capsule with some fatty food at a meal. Some take C,D3 and K2 at Breakfast, but with my thyroid meds I like to take supplements 4 hours after the thyroid meds so they do not interfere with absorption. Noon is best for me.
Vitamin D2 and vitamin D3 that are found in supplements are made differently:
- Vitamin D2 is made using UV irradiation of ergosterol in yeast. If you follow a vegan or vegetarian diet, vitamin D2 supplements are a suitable option.
- Vitamin D3 is made using irradiation of 7-dehydrocholesterol from lanolin (from sheep wool). It is also made from lichen and marketed as vegan or animal-free when it is sourced this way.
No matter which form of vitamin D you take (vitamin D2 or D3), they both need to get converted into the active form of vitamin D in your body. This happens in two steps. First, the liver converts vitamin D2 and D3 into 25-hydroxyvitamin D. Then, the kidneys convert 25-hydroxyvitamin D into the active form of vitamin D, calcitriol.
🏥 The Calcium is better absorbed when taken with Vitamin D3.
🏥 Take the Magnesium at supper time or bedtime.
🏥 When a supplement is fat soluble it should be taken with a fatty food. Vitamin D is fat soluble.
How Magnesium Affects Calcium
Magnesium and calcium are both essential minerals that work together in a tightly regulated system to maintain health, but they also have opposing roles in certain physiological processes.
1. Regulation of Calcium Levels
Magnesium is a cofactor for the enzyme that converts vitamin D into its active form, calcitriol. Active vitamin D is necessary for calcium absorption from the gut and for integrating calcium into bone structure scienceinsights.org+1. Without adequate magnesium, vitamin D activation is impaired, reducing calcium uptake. Magnesium is also required for the parathyroid glands to secrete parathyroid hormone (PTH), which mobilizes calcium from bone when blood levels are low. Low magnesium can cause functional hypoparathyroidism, leading to low blood calcium (hypocalcemia) scienceinsights.org+1.
2. Cellular and Nervous System Effects
At the cellular level, calcium is the primary trigger for muscle contraction, nerve signaling, and neurotransmitter release. Magnesium acts as a natural antagonist—physiologically blocking calcium channels—preventing excessive or prolonged excitation. This “braking” effect helps maintain muscle relaxation and prevents cramps, spasms, or tremors when magnesium is deficient scienceinsights.org.
3. Bone Health
Magnesium supports bone formation and helps prevent bone breakdown. Low magnesium levels are linked to reduced bone density and increased fracture risk, which can indirectly affect calcium balance by impairing calcium’s role in bone mineralization Health+1.
4. Supplement Interaction
When taken together, calcium and magnesium can interfere with each other’s absorption, so taking them separately may improve calcium uptake Health. Magnesium can enhance calcium absorption when taken at different times, supporting bone, brain, and heart health Verywell Health.
5. Clinical Implications
Magnesium deficiency can lead to low calcium levels, muscle twitching, and abnormal heart rhythms. Conversely, calcium deficiency can occur if magnesium is too low, as the body cannot properly regulate calcium. Maintaining adequate magnesium intake is therefore critical for optimal calcium function.
In summary: Magnesium regulates calcium by enabling vitamin D activation, supporting PTH secretion, and modulating calcium channels. It ensures calcium is absorbed, stored, and released in a controlled manner, making it a key player in bone health, muscle function, and nervous system stability scienceinsights.org+1.
Does Calcium “Jump Start” Vitamin D?
Calcium does not “jump start” vitamin D — the relationship works in the opposite direction. Vitamin D is the key that unlocks calcium absorption in your intestines, while calcium is the mineral that vitamin D helps your body use effectively EatingWell+1.
How Vitamin D Controls Calcium Absorption
When vitamin D is activated in your body (converted to calcitriol), it binds to receptors in intestinal cells and turns on genes that produce proteins needed to move calcium from your gut into your bloodstream scienceinsights.org.
Without enough vitamin D, you absorb only about 15% of dietary calcium.
With sufficient vitamin D, absorption can rise to ~30%, and during pregnancy or rapid growth, it can reach up to 80% scienceinsights.org.
Calcium alone cannot pass through the intestinal wall efficiently; vitamin D builds the transport system that makes absorption possible scienceinsights.org.
Why Calcium Doesn’t Trigger Vitamin D
Vitamin D is a fat-soluble vitamin made in your skin from sunlight exposure and obtained from certain foods or supplements. It is not produced in response to calcium intake. Instead, calcium status is regulated by vitamin D and parathyroid hormone, which adjust vitamin D activation to maintain blood calcium balance scienceinsights.org.
Practical Takeaway
Vitamin D is essential for calcium absorption — without it, calcium supplements or dietary calcium may not be effective. EatingWell.
Calcium supports bone mineralization and other bodily functions, but it doesn’t initiate vitamin D production.
For optimal bone health, experts recommend taking calcium and vitamin D together if you’re supplementing, especially if you have limited sun exposure or dietary intake EatingWell.
In short: Calcium doesn’t jump-start vitamin D — vitamin D is what “jumps-starts” calcium absorption.
Vitamin D is best absorbed when taken with a meal containing fats, and morning intake may align with your body’s natural rhythms, though the exact time of day is flexible.
Timing and Absorption
Vitamin D is a fat-soluble vitamin, meaning it dissolves in fats and oils. Taking it with a meal that contains healthy fats—such as avocado, nuts, seeds, olive oil, or fatty fish—enhances absorption significantly . Studies show that consuming vitamin D with the largest meal of the day can increase blood levels more effectively than taking it on an empty stomach or with a fat-free meal .
Morning vs. Evening
Many experts recommend taking vitamin D in the morning, often with breakfast, because it aligns with natural sunlight exposure and may support energy and mood throughout the day . Some research suggests that taking vitamin D late at night could potentially interfere with melatonin production, which may affect sleep, although evidence is mixed . Individual responses vary, so monitoring your sleep and energy levels can help determine the best personal timing.
Practical Tips
- Consistency matters more than exact timing: Take vitamin D at the same time each day to maintain steady blood levels .
- Pair with fat-containing meals: Breakfast, lunch, or dinner works, as long as the meal includes healthy fats .
- Use reminders: Place your supplement near your dining area, set an alarm, or use a pillbox to ensure regular intake .
- Adjust for lifestyle: If mornings are rushed, taking vitamin D with dinner is acceptable, provided it doesn’t disrupt sleep .
Summary
While there is no strict “best” time of day, taking vitamin D with a fat-containing meal is key for absorption. Morning intake may offer additional benefits for energy and alignment with natural circadian rhythms, but evening intake is also acceptable if it fits your routine and does not interfere with sleep. The most important factor is consistent daily supplementation to maintain adequate vitamin D levels .
Best Magnesium Forms for Supporting Calcium Activation
If your goal is to help activate calcium—and by extension support bone health, muscle function, and vitamin D metabolism—magnesium is the key cofactor. Magnesium is required for the body to convert vitamin D into its active form, which then regulates calcium absorption and utilization www.elementaledgehealth.com.
Why Magnesium Matters for Calcium
Vitamin D activation: Magnesium-dependent enzymes are needed to convert vitamin D into its active hormonal form www.elementaledgehealth.com.
Calcium balance: Magnesium helps maintain proper calcium levels and prevents calcium from crowding out magnesium in the intestines healthymag.org+1.
Bone health: Magnesium supports bone mineralization, density, and remodeling, working best in a 2:1 calcium-to-magnesium ratio HealthCentral+1.
Best Magnesium Forms for Calcium Activation
While all magnesium forms contribute to calcium metabolism, chelated forms are generally better absorbed and more effective for bone and mineral balance:
Magnesium Glycinate – Highly bioavailable, gentle on digestion, supports relaxation and sleep, which aids bone recovery Better Bones, Better Body.
Magnesium Citrate – Well-absorbed, supports energy metabolism, helps maintain alkaline balance that favors bone retention Better Bones, Better Body.
Magnesium Ascorbate – Pairs magnesium with vitamin C for antioxidant support and collagen formation, important for bone flexibility Better Bones, Better Body.
Magnesium Aspartate – Very well absorbed, supports calcium and vitamin D metabolism, and helps reduce bone breakdown Better Bones, Better Body.
For osteoporosis or bone health, a blend of these forms (e.g., glycinate + citrate + ascorbate) is often recommended to cover multiple pathways for bone strength Better Bones, Better Body.
Practical Tips
Dosage: Aim for 300–500 mg magnesium daily, depending on your needs and tolerance HealthCentral.
Timing: Take magnesium with meals to reduce GI upset; split doses if needed HealthCentral.
Synergy: Pair with adequate vitamin D and calcium, but maintain the 2:1 calcium-to-magnesium ratio to avoid competition for absorption HealthCentral+1.
Food sources: Include magnesium-rich foods (leafy greens, nuts, seeds, whole grains) alongside supplements for best results healthymag.org.
Bottom line: For activating calcium, choose well-absorbed, chelated magnesium forms like glycinate, citrate, ascorbate, or aspartate, ideally in a blend, and maintain a balanced calcium-to-magnesium ratio for optimal bone and mineral health.
The Migraine is gone now. I rested and let the meds take charge. Working on laundry today and rearranging some Kitchen shelves. At 3 in the morning I got the BOSS IDEA of rearranging some shelves. I restrained myself and decided to do this during the daylight hours. Needed to sleep.
Here in a bit, we're going to go to the in-town storage unit to re-evaluate what to do with THE STUFF in there. I know there is a small antique framed mirror that I want to bring HOME. I may make a wall of mirrors on the wall behind the living room sofa. Maybe. Maybe.
Do you suffer from Migraines? Do you know why you have them? Hormonal issues? Vitamin deficiencies? Stress?
Blessings and then some,
