Why These Supplements (Diabetes-Focused)

Short, patient-friendly reasons—one line each.

Benfotiamine (B1)

Helps protect the body from sugar damage that builds up over years in diabetes.

Vitamin B12

Supports nerves, memory, and energy—and prevents common deficiency after gastric bypass.

NAC

Helps protect cells and organs from long-term “wear-and-tear” that diabetes can speed up.

Nattokinase

Supports smooth blood flow and circulation—important because diabetes can affect blood vessels.

Magnesium

Supports sleep, muscle relaxation, and helps the body handle blood sugar better.

Vitamin D3 + K2

D3 supports the immune system and bones. K2 helps keep calcium in bones and out of arteries.

Zinc

Supports the immune system and healing—which can be slower in diabetes.

Safety Notes (Important)

A few common-sense rules to keep this safe.

When to check first

  • Blood thinners (warfarin, Eliquis, Xarelto, etc.) or bleeding disorders
  • Kidney disease or kidney stones (discuss D, magnesium dosing)
  • Upcoming surgery or dental procedures (may hold certain supplements)
  • Pregnancy or breastfeeding (supplement plans should be individualized)

Recommended lab checks

  • Vitamin D level (25-OH Vitamin D)
  • B12 status (B12 ± MMA if needed)
  • Kidney function (BMP/CMP)
Tip: Bring your supplement bottles to your appointment so we can verify doses and avoid duplicates.

Do Low-Carb, Keto, Ketovore, or Carnivore Diets Provide Enough Vitamin B12?

Yes — when animal foods are eaten, these diets naturally contain plenty of vitamin B12.

Vitamin B12 is found almost exclusively in animal foods, including:

  • Beef, lamb, pork
  • Fish and shellfish
  • Eggs
  • Cheese and other dairy (if included)

Because FitZone patients follow animal-based, low-carbohydrate diets, most patients actually get more vitamin B12 from food than people eating standard or plant-heavy diets.


So why do some patients still need B12 supplements?

The issue is absorption — not diet.

Some people cannot absorb vitamin B12 normally, even when they eat enough of it. This includes patients with:

  • Gastric bypass surgery
  • Low stomach acid
  • Autoimmune gastritis or pernicious anemia
  • Long-term acid-blocking medications
  • Older age

👉 That’s why FitZone may recommend high-dose oral or sublingual vitamin B12, which can absorb even without normal stomach function.
