Never Get Menstrual Cramps Again (13 Scientifically Proven Tips)

Berg explains that vitamin D has two physiological systems: one for bone and calcium regulation, and another for immune and soft tissue function that requires daily dosing. He criticizes existing studies for using infrequent megadoses (300,000 IU once monthly or 50,000 IU weekly) that only raised blood levels to 30 ng/mL, which he deems insufficient. He advocates daily dosing to saturate tissues before menstruation. He emphasizes the synergy with magnesium: without magnesium, vitamin D remains inactive; without vitamin D, magnesium absorption is impaired. He recommends magnesium glycinate for its high bioavailability (80% absorption vs. 3% for magnesium oxide). He also notes that many common conditions (insulin resistance, obesity, darker skin) increase the required dose, so 20,000 IU daily is a starting point.

Berg argues that insulin resistance is a major hidden barrier to resolving vitamin D deficiency. He states that when you have insulin resistance, 'vitamin D is not going to be going in or being absorbed near as well.' He points to diabetics as an example of poor vitamin D absorption. Therefore, simply taking vitamin D may not be enough if the diet remains high in carbohydrates. He recommends a healthy ketogenic diet as a way to tackle this barrier at its root, making the vitamin D protocol more effective. This is presented as a necessary co-factor, not an optional add-on.

Berg contrasts intermittent fasting with the common advice to eat six small meals a day. He asserts that eating less frequently speeds up the improvement of insulin sensitivity, thus boosting vitamin D absorption. He suggests that combining intermittent fasting with a low-carb diet creates a powerful synergy to overcome insulin resistance, making the vitamin D protocol far more effective. This is the third pillar of his core strategy.

Berg begins by noting that the true cause of menstrual cramps is never mentioned in mainstream sources. He walks through clues from Wikipedia: cramps involve prostaglandins (pain chemicals), elevated vasopressin (causing vasoconstriction), high parathyroid hormone (leading to erratic calcium mobilization and muscle spasms), increased NF-kB-driven inflammation, a 33% higher prevalence in black women, and the fact that calcium channel blockers are sometimes used — indicating excessive calcium-driven contraction. He then demonstrates how vitamin D3 directly counters each factor: it downgrades prostaglandins, suppresses vasopressin, lowers parathyroid hormone by enabling dietary calcium absorption (so the body doesn't need to pull calcium from bones), acts as a potent anti-inflammatory by turning off NF-kB, and explains that melanin in darker skin blocks UV, causing higher deficiency rates and thus more cramps and fibroids. He also asserts that fibroids, endometriosis, and ovarian cysts are themselves manifestations of severe vitamin D deficiency, and that shrinking benign tumors requires blood levels above 90 ng/mL. Berg criticizes Wikipedia for claiming insufficient evidence for natural remedies while ignoring the side effects of NSAIDs and birth control. He emphasizes that this information is suppressed because it falls outside medical consensus, which is influenced by biased groups.

Berg explains that PTH's job is to keep blood calcium stable. When vitamin D is low, calcium absorption from the gut drops, so PTH rises to pull calcium from bones. This process is erratic and can cause smooth muscle cramps, tetany, and spasms. He notes that some women get relief from calcium gluconate because providing calcium suppresses PTH, but the root fix is vitamin D, which allows dietary calcium absorption and keeps PTH low. He emphasizes that 'when you have a high parathyroid hormone, all that means is you don't have enough vitamin D.' This insight ties together the calcium channel blocker clue and the muscle contraction problem.

Berg points out that black women have a 3-9 times increased risk of fibroids and 33% more severe cramps, which he attributes to melanin blocking UV and causing lower vitamin D levels. He then states that fibroids, endometriosis, and ovarian cysts are all severe vitamin D deficiency states. He references data suggesting that to shrink a benign tumor, vitamin D blood levels must exceed 90 ng/mL, far above the typical 20-40 ng/mL considered 'normal'. He implies that standard vitamin D dosing will not achieve this, and that aggressive supplementation is needed. This connects the dots between the higher prevalence in darker-skinned women and the root cause.

Berg explains that menstrual cramps involve too much calcium inside smooth muscle cells, causing contraction. Calcium channel blockers are sometimes used to treat cramps, but magnesium is a natural calcium channel blocker that promotes relaxation. He stresses that anytime you have a cramp, you need more magnesium. Crucially, he notes the bidirectional dependency: vitamin D requires magnesium for its activation and function, and magnesium requires vitamin D for absorption and utilization. Therefore, supplementing vitamin D without magnesium is ineffective, and vice versa. This is why he pairs them in his main protocol.

Berg opens by stating that the root cause is never mentioned, and he knows why: it's not part of medical consensus, which is influenced by biased groups. He notes that searching Google or ChatGPT yields no mention of vitamin D deficiency as a cause. He then reads from Wikipedia's alternative medicine section, which states there is insufficient evidence to recommend many herbal and dietary supplements, and that safety evidence is insufficient. He finds it fascinating that they highlight lack of safety evidence for natural things while ignoring the side effects of NSAIDs, birth control pills, and Depo-Provera. He implies a double standard designed to discourage alternatives. This sets up his entire presentation as a counter-narrative to mainstream information.
