Source Naturals Wellness Transfer Factor 125MG (60 Capsules)
Technologically Advanced Immune Intelligence and Cellular Communication Support
Your immune system is your body’s frontline defense, working around the clock to recognize microscopic intruders, coordinate responses, and remember past encounters. While everyday supplements like Vitamin C and Zinc supply raw nutritional building blocks, Source Naturals Wellness Transfer Factor 125MG provides something fundamentally different: immune intelligence.
Extracted from premium bovine colostrum through precision ultrafiltration, Wellness Transfer Factor delivers concentrated, low-molecular-weight messenger peptides. These messengers act as chemical blueprints that train and balance your body’s natural immune responses without overstimulating your system.
Key Benefits at a Glance:
✓Transfers Immune Knowledge: Delivers biologically active signaling peptides that help naive immune cells recognize challenges faster.
✓Concentrated Polyvalent Extract: Contains 12.5 mg of pure polyvalent transfer factors derived from 125 mg of fractionated colostrum per capsule.
✓Modulates Without Over-Exciting: Promotes balanced cellular immunity (Th1 pathway) and natural killer (NK) cell readiness.
✓Clean Allergen Profile: Free from yeast, egg, gluten, soy, wheat, sugar, salt, artificial colors, and artificial flavors.
How Transfer Factors Work: The Science in Simple Terms
Think of your immune cells as recruits in a defensive academy. When your body encounters a new environmental threat, inexperienced (naive) white blood cells must figure out how to respond from scratch. This learning process can take days.
Transfer factors are like molecular flashcards. They are not vitamins, minerals, herbs, or antibodies. Instead, they are tiny peptide molecules (short protein chains) that carry immunological memory. When you ingest them, they share lessons learned by experienced immune cells directly with your own cells. This communication network performs three essential jobs:
1. Recognize
They alert resting white blood cells to unseen challenges so your defense network can identify potential issues much sooner.
2. Respond
They assist in mobilizing natural killer (NK) cells and cytotoxic T-cells, coordinating an organized response without hyper-reactivity.
3. Remember
They help store the biochemical profile of foreign markers, allowing your system to react with greater efficiency in future encounters.
Because transfer factor molecules are non-species-specific, information gained by healthy dairy cows can be safely and biologically transferred to the human immune system.
Transfer Factor vs. Regular Colostrum: What Makes SN1816 Unique?
Many shoppers ask: "Can't I just take whole colostrum powder?" While whole bovine colostrum is an exceptional nutritional food, it serves a distinct purpose compared to concentrated transfer factor fractions.
Feature
Standard Whole Colostrum
Source Naturals Wellness Transfer Factor
Molecular Size
Large proteins (up to 160,000 Daltons)
Ultra-small peptides (< 10,000 Daltons)
Primary Function
Provides antibodies (IgG), gut repair, and growth factors
Cellular education and immune modulation
Dairy Protein / Casein Content
Contains whole milk solids, casein, and lactose
Fractionated to remove bulk casein and fats
Digestive Absorption
Partially broken down by stomach acid as protein
Survives gastric passage on an empty stomach
Source Naturals isolates the dialyzable leukocyte extract fraction from colostrum, giving you pure signaling power in an easy-to-swallow single capsule rather than large scoops of dairy powder.

Directions for Use: Why Taking on an Empty Stomach Matters
To experience optimal benefits from Wellness Transfer Factor 125MG, timing is critical:
Standard Daily Wellness Protocol:
Take 1 capsule daily with an 8 oz glass of water on an empty stomach. Wait at least 30 minutes before consuming food.
During Times of Increased Physiological Stress:
During seasonal changes, intense travel, or elevated physical strain, dosage may be increased up to 3 to 5 capsules per day, taken in divided doses on an empty stomach, or as directed by your physician.
The Science of the 30-Minute Empty Stomach Window
When you eat, your stomach produces concentrated hydrochloric acid and digestive enzymes like pepsin to break down whole protein foods. Because transfer factors are low-molecular-weight peptides, taking them with a meal risks having them digested as ordinary food. Taking them with plain water when your stomach is empty allows the intact peptides to pass swiftly into your small intestine. There, they interact directly with specialized immune hubs known as Peyer’s patches (part of your Gut-Associated Lymphoid Tissue, or GALT), where immune education takes place.

Frequently Asked Questions (FAQ)
What exactly is Source Naturals Wellness Transfer Factor 125MG?
It is a specialized dietary supplement containing 12.5 mg of polyvalent transfer factors extracted from 125 mg of fractionated bovine colostrum. Transfer factors are low-molecular-weight messenger peptides that help train and support your immune system's natural surveillance and response capabilities.
How is this different from drinking or taking regular colostrum powder?
Whole colostrum contains large protein structures (immunoglobulins like IgG), milk fat, casein, and lactose. Source Naturals uses advanced micro-filtration to extract only the tiny signaling molecules (under 10,000 Daltons) while eliminating bulk milk proteins. This delivers targeted immune education in a small, concentrated capsule.
Why do I have to take it on an empty stomach and wait 30 minutes?
Taking transfer factors on an empty stomach prevents them from being digested as ordinary food by harsh stomach acids and digestive enzymes. A 30-minute window allows these tiny peptide chains to migrate intact into the small intestine, where your gut's immune tissue can absorb and process their cellular messages.
Can I take this if I have a dairy or lactose sensitivity?
Because the product is derived from bovine colostrum, it carries an allergen warning for milk derivatives. Although the ultrafiltration process separates out the vast majority of milk solids and lactose, individuals with severe, life-threatening dairy or beef allergies should consult their allergist before using this product.
Can I take more than one capsule per day?
Yes. The recommended daily baseline for general wellness is 1 capsule per day. However, during periods of physical exhaustion, seasonal stress, or demanding schedules, the manufacturer's suggested use permits taking up to 3 to 5 capsules per day in divided doses, or as advised by your healthcare professional.
Should this product be refrigerated?
Yes. To preserve the bioactivity of the natural peptide chains, keep the bottle tightly sealed in a cool, dry place prior to use, and store it in the refrigerator after opening.
