Getting the Wrong Vitamin D Can Lower Your Levels

True health isn’t just the absence of disease — it’s the body’s ability to adapt.
When you’re healthy, your body can bend without breaking, adjust without crashing, and return to balance after every challenge.
Our immune system isn’t static — it shifts with the seasons. As daylight, temperature, and humidity change, so do our hormones, microbiome, and nutrient needs.
For example Cortisol and Melatonin rhythms adapt to less sunlight in the Fall and Winter which can be taxing on your immune system especially if you have pre-existing adrenal imbalances.
The master agent needed to help us stay strong through seasonal transitions (especially through Fall & Winter) is Vitamin D.
A study done by ‘Classic Research’ concluded that October through March were the ideal months to supplement or even increase your dosage of supplemental Vitamin D. As daylight fades, your body’s natural ability to make Vitamin D3 from sunlight sharply declines. Between October and March, UVB rays are too weak in most regions to trigger Vitamin D synthesis in the skin — even in sunny climates like California.
Vitamin D deficiency can feel like:
- Brain Fog
- Fatigue
- Mood Swings
- Depression
- Chronic Illness
- Hormone Imbalances
Vitamin D functions very much like a hormone, regulating almost every major system in our body including your:
- Endocrine system
- Immune System
- Nervous System
- And plays a major part in bone strength.
There are 5 different forms of Vitamin D, and taking the wrong form can actually lower your Vitamin D blood levels.
Research published in the Journal of Clinical Endocrinology & Metabolism (Armas et al., 2004) found that when subjects took Vitamin D2, their total active Vitamin D levels initially rose but then fell below baseline within two weeks — even lower than before supplementation!
Common hidden places where Vitamin D2 shows up:
- Multi-Vitamins
- Fortified milks (including plant-based options)
- Fortified breads and cereals
Read those labels!
Why It's Essential to Take a D3 That Contains K2
While Vitamin D3 enhances calcium absorption, Vitamin K2 directs calcium into bones and teeth instead of soft tissues.
Together they:
Promote strong bones and teeth
Support cardiovascular and arterial health
Balance hormones and mood
Reinforce immune function
Liposomes Enhance Absorption
Traditional capsules rely on digestion, where nutrients can degrade before absorption.
Our Nanosol D3 uses liposomal sublingual delivery, allowing D3 + K2 to absorb directly through the mouth’s mucosal tissues for rapid, efficient uptake.
This means your body receives more of the active nutrients — faster.
The Takeaway
From October through March, most people experience a drop in Vitamin D levels — and factors like age, stress, and limited sun exposure compound the deficiency.
Multivitamins or foods that contain Vitamin D2 can lower your Vitamin D levels. (Vitamin D2 can be listed as Ergocalciferol or sometimes just Vitamin D)
A True Vitamin D3 will be listed as "Cholecalciferol"
Choosing a bioavailable, liposomal D3 + K2 supplement such as Nanosol D3 ensures:
- Superior absorption
- Targeted calcium utilization
- Strong immune and hormonal balance year-round
Support your body the way nature intended — with the active form it already knows how to use!
