Does sunscreen reduce vitamin D absorption in the body?

Yes, sunscreen can block the UVB rays from entering the skin, which ultimately reduces vitamin D absorption in the body. Spending a few minutes in early-morning sunlight is essential to maintain healthy vitamin D levels.

How long does it take to recover from vitamin D deficiency?

Generally, it can take up to 12 weeks of doctor-recommended supplements and tips to recover from vitamin D deficiency.

Can vegans get vitamin D naturally?

Yes, vegans can also get vitamin D naturally, though most sources are animal-based. Consume nutrient-rich foods, such as mushrooms, and supplements as advised by your nutritionist.

Vitamin D Deficiency in Winter: The Hidden Fertility Challenge

While winter is all about cold weather, cosy blankets, and longer nights, it also brings couples together and strengthens their bond. But the season also brings a common fertility challenge in couples, i.e., Vitamin D deficiency! In winter, shorter days and longer nights reduce sunlight exposure, which disrupts vitamin D production in the body.

Many people believed that vitamin D supports bone health, but it also plays a significant role in determining reproductive health in both men and women. From regulating estrogen and progesterone in women to maintaining optimal sperm count, motility, and morphology, vitamin D is a powerhouse nutrient for enhanced fertility. Medical science even suggests that a deficiency of vitamin D may lead to reduced fertility and a lower chance of conception.

Let’s understand the connection between vitamin D and fertility.

How Does Vitamin D Deficiency Affect Fertility in Men & Women?

If vitamin D levels drop in the body, it can significantly impact the hormonal and reproductive function in both men and women. Here’s how vitamin D deficiency affects fertility.

Irregular Menstrual Cycles: If a woman is deficient in Vitamin D, it can affect their progesterone and estrogen levels, which are essential for regulating menstrual cycles. When these hormones fluctuate, it may lead to irregular cycles, which ultimately impacts fertility and reduces the chances of conception.
Reduced Sperm Quality: Just like for women’s hormones, vitamin D is equally essential for men, as well. If a man has a vitamin D deficiency, they’ll have lower testosterone levels, reduced sperm count and quality. Thus, a male’s sperm will not swim effectively to reach a woman’s egg, which means lower chances of successful conception.
Increased Risk of PCOS: Medical research suggests that vitamin D deficiency is one of the biggest causes of infertility in women. Remember that lower levels of vitamin D can worsen insulin resistance, increase male hormone (androgen) production, and disrupt ovulation. With such factors combined, they can cause PCOS and impact women’s fertility.
Weak Immunity: Vitamin D supports healthy immune function in both men and women. If anyone has a weakened immune system, it can increase inflammation in the body and cause reproductive issues. In men, vitamin D deficiency can damage the sperm membrane due to increased inflammation. On the other hand, it can cause scarring in women’s fallopian tubes, which blocks the sperm’s path for a fertilised egg.

Essential Tips to Maintain Vitamin D Levels in Winter & Boost Fertility

During winter, shorter days and longer nights can make it challenging for the body to maintain healthy vitamin D levels. Here’s what doctors recommend to maintain adequate vitamin D levels and boost fertility in men and women.

Get Adequate Sunlight

Irrespective of your busy schedule, expose yourself to early morning sunlight between 8 am and 10 am for at least 20 minutes. During this time, the sun’s UVB rays are mild but ideal for vitamin D synthesis in the body. Don’t wear sunscreen. Simply expose your skin to the sun for a few minutes to maximise vitamin D production.

Prioritise Nutrition-Rich Foods

Food plays an essential role in maintaining optimal vitamin D levels in the body. Consume vitamin D-rich foods like eggs, salmon, sardines, milk, and cheese to increase vitamin D levels and boost your fertility. If you are a couple planning for conception, start eating such foods to reap maximum reproductive-related benefits.

Note: Before adding vitamin D-enriched foods to your diet, consult your nutritionist to keep digestion-related issues at bay.

Add Supplements (if Needed)

If you’re facing low vitamin D symptoms, you can add D3 supplements to your diet. However, self-supplementation can be dangerous and lead to toxicity. Always consult your nutritionist to test your vitamin D levels before starting any form of medications or supplements. Remember that your doctor will determine the correct dosage based on your test reports.

Don’t Overlook Physical Activity

Regular exercise is essential for increasing vitamin D levels in the body. When you engage in endurance-based physical activity, such as running, walking, or gymming, it mobilises the vitamin stored in adipose tissue, thereby releasing it into the blood. Medical science suggests that exercising in winter helps prevent the drop in vitamin D levels that often occurs during cold weather.

Note: Always consult your doctor before engaging in any endurance-based physical activity to check for underlying medical conditions.

While winter is a season that brings couples together, it’s also the best time for conception due to better sleep and the availability of nutrient-rich foods. However, couples often struggle with conception in winter due to vitamin D deficiency. Keeping the above-mentioned tips in mind will help prevent vitamin D deficiency while boosting fertility in men and women.
