Collagen
Also known as: Collagen Peptides, Hydrolyzed Collagen, Collagen Powder, Gelatin
Collagen is the most abundant protein in the human body, forming the structure of skin, bones, cartilage, tendons, and ligaments. Collagen supplements are typically derived from bovine, marine, or plant sources and are hydrolyzed into small peptides for enhanced absorption. There are multiple collagen types, with types I, II, and III being most relevant for supplementation.
Benefits
Improves skin elasticity and hydration; reduces wrinkles and promotes youthful appearance; supports joint health and reduces osteoarthritis pain; strengthens bones and may reduce fracture risk; improves hair and nail quality; supports gut lining integrity and gut health; enhances muscle recovery and strength.
Recommended Dosage
Typical doses range from 2.5-15 grams daily, with most research using 10 grams as an effective dose. Collagen hydrolysate is best absorbed on an empty stomach or with vitamin C to enhance synthesis. Consistency over time is important; benefits typically emerge after 4-8 weeks of daily use.
Food Sources
Collagen-rich foods include bone broth, chicken skin and cartilage, beef tendons, fish skin, and connective tissues. However, cooking breaks down collagen into gelatin; obtaining therapeutic supplement doses from food requires consuming large quantities of these specific tissues.
Side Effects
Very well-tolerated in most individuals. Rare side effects include mild digestive upset, bloating, or constipation. Some report a mild aftertaste with certain formulations. Allergic reactions are uncommon but possible in those sensitive to the animal source (beef, fish, or eggs).
Interactions
No significant interactions with medications reported. Collagen works synergistically with vitamin C, iron, and copper for optimal synthesis. Taking with meals does not affect absorption. Generally compatible with other supplements and medications.
Warnings
Those with allergies to beef, fish, or poultry should verify the source before use. Some collagen supplements may contain additives or fillers; choose reputable brands. Individuals with phenylketonuria (PKU) should check labels for aspartame. Not established as safe during pregnancy without medical guidance.
Deficiency Symptoms
Collagen decline with age leads to wrinkled and sagging skin, joint pain and stiffness, weakened bones prone to fractures, brittle hair and nails, and reduced muscle mass. However, this is an age-related decline rather than a classical deficiency state.

Vitamin D
Vitamins
Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, immune function, and mood regulation. Unlike most vitamins, your body can produce vitamin D when your skin is exposed to sunlight, earning it the nickname 'the sunshine vitamin.'
Vitamin C
Vitamins
Vitamin C is a water-soluble vitamin and powerful antioxidant that the human body cannot produce on its own. It is essential for the growth, development, and repair of all body tissues and plays a role in many body functions including immune defense, collagen formation, and iron absorption.
Omega-3 Fish Oil
Fatty Acids
Omega-3 fatty acids are essential polyunsaturated fats that your body cannot make on its own. The two most important omega-3s found in fish oil are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They play critical roles in brain function, heart health, and reducing inflammation throughout the body.
