Wound healing supplements – What should you use after major injuries?

Wound healing – how does it happen?⁴

Wound healing is a highly complex, multi-stage biological process in which the body defends, clears, rebuilds and fine-tunes at the same time.

There are three main stages, each with different nutritional requirements.

1. the inflammatory phase (0–3 days),
2. the proliferative phase – building new tissue (3–21 days),
3. and the remodelling or maturation phase (from day 21 up to 1 year).

1. Inflammatory phase – the body’s “firefighting” response

This phase is not bad, nor is it “harmful inflammation”; it is a necessary part of healing. However, if it is too short or too prolonged, the wound may not heal properly.

Nutrient needs in this phase:

• Antioxidants (vitamins C and E)
• Zinc
• Omega-3 fatty acids (to help regulate inflammation)
• Protein and amino acids (for immune cell function)

2. Proliferative phase – new tissue is built

This is the “construction” phase of wound healing. It usually starts around day 3 and can last for 2–3 weeks. It involves collagen production and the growth of new blood vessels. This is when the wound closes, fills in and stabilises. If the body does not receive enough protein, vitamin C, zinc or amino acids, collagen production slows down.

Nutrient needs in this phase:

• Vitamin C (collagen formation)
• Zinc (cell division)
• Arginine (nitric oxide → improved blood flow)
• Glutamine (energy source for rapidly dividing cells)
• Protein and essential amino acids
• Copper (for collagen cross-linking)

3. Remodelling phase – the tissue becomes stronger

This phase can last up to 12 months. Collagen fibres reorganise and strengthen. The wound gradually regains tensile strength, although it never returns to 100%. The scar becomes paler and flatter. This stage determines how strong the scar will be, how flexible the tissue becomes, and what the final function will look like, for example the range of motion of a joint.

Nutrient needs:

• Collagen and amino acids
• Vitamin C
• Copper
• Zinc
• Vitamin D (for general regenerative processes)

Why are these three phases important when choosing supplements?

Because not every supplement is equally effective in every stage, while vitamin C and zinc are critical in almost every phase.

Arginine and glutamine are especially useful in the middle, proliferative phase.

Collagen and copper are particularly important in the final remodelling phase.

Omega-3 can be helpful in the first, inflammatory phase, but in high doses it may slow blood clotting, so it should be used with caution after surgery.

This is why it makes sense to look at supplements by the three main types of injury: cuts, burns and bone fractures.

What is recommended after cuts and surgical incisions?

The healing of cuts depends primarily on collagen synthesis, an appropriate immune response and cell division. Research has identified several nutrients that may accelerate wound closure and reduce the risk of infection.

Vitamin C (ascorbic acid)⁵

Vitamin C plays a key role in collagen formation and immune function. Deficiency slows wound closure. According to the literature, vitamin C supplementation may accelerate wound healing in different types of injuries.

Zinc⁶

Zinc is essential for DNA synthesis and cell division. Zinc deficiency has been shown to impair wound healing, while supplementation can help accelerate the process.

Arginine⁷

Arginine supports blood flow and nutrient delivery around the wound through nitric oxide production. Clinical studies suggest that arginine-containing formulas may accelerate wound closure and reduce inflammation.

Glutamine⁸

Glutamine is one of the main energy sources for rapidly dividing cells, including immune cells and fibroblasts. It may be especially useful for surgical wounds and major trauma.

HMB (β-hydroxy-β-methylbutyrate)⁹

HMB is produced from the breakdown of leucine. By reducing muscle breakdown and supporting protein synthesis, it can aid recovery. Several studies suggest that combined formulas containing arginine, glutamine and HMB may be particularly effective.

What is recommended for burn injuries?

Burn injuries are among the most nutrient-demanding types of trauma. The body uses extreme amounts of protein, amino acids and antioxidants for recovery. Studies suggest that targeted nutrition can significantly improve healing time and even survival.

High protein intake + essential amino acids¹⁰

Burn injuries create a catabolic state. Protein and amino acid supplementation, including arginine, glutamine and leucine, has been shown to accelerate healing.

Glutamine¹¹

Glutamine is one of the most important supplements in burn injuries. It supports immune function, may reduce infection rates and helps accelerate wound closure.

Zinc + copper + selenium¹²

These minerals have antioxidant and immune-supporting roles. Zinc and copper are particularly important for collagen formation and epithelial regeneration.

Vitamins C and E¹³

These are powerful antioxidants that help reduce tissue damage and support collagen synthesis. In burn injuries, the need for vitamin C increases dramatically.

Omega-3 fatty acids¹⁴

Omega-3 fatty acids have anti-inflammatory effects. Some studies suggest that they may improve wound healing and reduce inflammatory markers.

What is recommended for bone fractures?

Bone regeneration has three main stages: inflammation, callus formation and bone remodelling. For this, the body needs a large amount of minerals, protein and vitamins.

Vitamin D¹⁵

Vitamin D is fundamental for calcium absorption and bone metabolism. Deficiency can slow fracture healing.

Vitamin K2 (MK-7)¹⁶

Vitamin K2 supports calcium incorporation into the bone matrix. It is more effective when combined with vitamin D.

Calcium and magnesium¹⁷

These are basic building blocks of bone formation. Supplementation is useful when the diet does not cover daily needs.

Hydrolysed collagen¹⁸

Bone is built on a collagen matrix. Collagen peptides may increase osteoblast activity and improve bone mineral density.

Arginine + glutamine + HMB combination^7-9

Research suggests that this combination may be beneficial not only in soft-tissue healing but also in bone regeneration, as it supports protein synthesis and cellular energy supply.

Vitamin360’s general recovery protocol by injury type and healing phase

1. Cuts / surgical incisions

Days 1–3: Inflammatory phase

Goal: infection prevention, immune support and stabilisation of blood clotting.

Recommended:

• Vitamin C: antioxidant support
• Zinc: immune function and cell division
• Low-dose omega-3 (only if there is no post-surgical bleeding risk)
• Protein + essential amino acids
• Glutamine (energy supply for immune cells)

Avoid:

• High-dose omega-3 (due to bleeding risk)
• Excessively high doses of strong antioxidants, as inflammation is a natural process and should not be over-suppressed

3. Day 3 – week 3: Proliferative phase

Goal: collagen formation, building new tissue and accelerating wound closure.

Recommended:

• Regular daily vitamin C intake
• Zinc + copper (for collagen cross-linking)
• Arginine (for improved blood flow)
• Glutamine (support for rapidly dividing cells)
• HMB + protein (to reduce catabolism)

3. Week 3 – 12 months: Remodelling phase

Goal: strengthening the scar and reorganising collagen.

Recommended:

• Collagen peptides + vitamin C
• Zinc + copper
• Vitamin D
• Moderate omega-3

2. Burn injuries

Days 1–3: Inflammatory phase

Goal: infection prevention and reduction of oxidative stress.

Recommended:
