Sun replacement = Vitamin D (need 60 to 100 ng) - video
YouTube 26 minutes German
The video "Vitamin D: Panikmache im WDR oder echte Gefahr?" features a critique of a WDR article based on Stiftung Warentest findings that warn about Vitamin D overdosage. The speaker argues that the true danger in Germany is widespread deficiency rather than toxicity.
Summary of Key Points
Critique of Official Warnings (00:01 - 01:20):
The speaker satirizes the media's focus on overdosage, noting that German clinics are not actually filled with people suffering from Vitamin D toxicity. He argues that the danger of deficiency is much more prevalent than the risk of taking too much.
Individualized Dosage Rule of Thumb (01:20 - 02:20):
While official guidelines are low, the speaker suggests a rule of thumb: 1,000 IU per 10 kg of body weight. He emphasizes that dosage is highly individual and depends on health status, weight, and physical or emotional stress.
Impracticality of Recommended Products (02:20 - 04:30):
Stiftung Warentest recommended low-dose products like Rotbäckchen juice. The speaker points out that to reach a healthy Vitamin D level, one would need to drink several liters of this expensive juice daily, whereas high-quality drops are more effective and cost-efficient.
The "Fall Risk" Controversy (04:30 - 06:30):
Addressing the claim that Vitamin D increases fall risks, the speaker explains this only occurs with bolus dosing (massive doses taken once a month or week). These spikes cause a sudden surge in calcium absorption that can disrupt coordination. He advocates for daily intake to maintain stability.[1]
Widespread Deficiency in Germany (06:30 - 08:28):
While the Robert Koch Institute (RKI) claims nearly half of Germans are well-supplied, the speaker asserts that almost 100% of the population is deficient if the target is a healthy 50 ng/ml. He suggests that those working with patients see the clinical reality of deficiency-related pain more clearly than those looking only at averages.
Importance of Blood Testing (08:28 - 10:26):
Instead of "self-experimenting" blindly, the speaker urges viewers to get professional blood tests. He considers a level between 60 and 100 ng/ml to be ideal and notes that Vitamin D is a pro-hormone required by every cell in the body, from the immune system to the joints.
Scientific Reality of Sun Exposure (12:35 - 15:30):
The speaker dismisses the advice that 12 minutes of sun twice a week is sufficient. He clarifies that in Germany, Vitamin D can only be produced between late April and early September, ideally between 11:00 AM and 3:30 PM with 40% of the skin exposed for 20 minutes daily.
Storage and the "Winter Gap"
(15:00 - 16:00): Since the body can only store Vitamin D for a few months, levels typically hit rock bottom between January and March, which coincides with the peak of seasonal illnesses and immune system failure.
Nutritional Limits and Safety (19:50 - 22:37):
He emphasizes that Vitamin D is a "sun replacement," not a food supplement, as diet only provides 10-20% of needs. While extreme overdosage (drinking entire bottles daily for months) can cause calcium deposits in vessels, he notes there is no evidence of a "Vitamin D pandemic" in intensive care units.
