Multi + Lifetime Vitamins Soft Chew Supplement
Verified Jun 30, 2026
This is a daily multivitamin soft chew supplement for dogs of all ages, designed to be given alongside a complete and balanced diet. It provides a broad mix of vitamins and minerals plus added colostrum, spirulina, yeast, kelp, liver powder, egg yolk, and probiotics to help support overall wellness. The chewable format makes it easier for many dogs to take compared with traditional tablets or capsules.
Overall, this is a well-rounded canine multivitamin/mineral supplement with several thoughtful extras, like colostrum, spirulina, yeast, kelp, and a probiotic strain. It’s intended to complement a regular dog food diet rather than replace it, and may be useful for dogs who need a nutritional “backup” or those on less complete diets. As with any supplement, it’s important to make sure it fits with your dog’s existing food and any other supplements or medications to avoid over-supplementation of certain nutrients.

At a Glance
KibbleLab Review
Strengths
- Provides a wide spectrum of essential vitamins and minerals, which can help fill small gaps in an otherwise complete diet.
- Includes functional ingredients such as colostrum, spirulina, Atlantic kelp, yeast, liver powder, and egg yolk that can add additional nutrients and bioactive compounds.
- Contains Lactobacillus acidophilus, a probiotic species that may help support a healthy gut microbiome in some dogs.
- Soft chew form is generally palatable and convenient for owners, which can improve consistency of daily use.
Considerations
- This is designed to be used with a regular dog food, not as a stand-alone diet, so using it in place of a complete food could lead to imbalances.
- Because it contains multiple fat-soluble vitamins and several minerals, combining it with other vitamin/mineral supplements or high-dose treats could potentially push some nutrients toward excessive levels over time.
- Includes liver powder and egg yolk, which are nutritious but could be an issue for dogs with known sensitivities to liver or egg.

Top 5 Ingredients Explained
01
Vitamin A
Vitamin A is a fat‑soluble vitamin commonly added to pet foods to support vision, growth, immune function and reproduction in both dogs and cats; cats cannot efficiently convert plant provitamin A (beta‑carotene) to active vitamin A and therefore require preformed vitamin A from animal sources. Adequate levels are essential and are supplied via fortified commercial diets or animal ingredients (e.g., liver, fish oil), but excessive intake — especially from supplements or frequent liver treats — can cause hypervitaminosis A with bone and joint issues, while deficiency leads to night blindness, poor growth and skin problems.
02
Beta-Carotene
Beta-carotene is a natural carotenoid used in pet foods as an antioxidant and natural colorant and can serve as a provitamin A source in species that convert it to retinol. Dogs can partly convert beta-carotene to vitamin A and may benefit from its antioxidant and immune-supporting properties, whereas cats convert it poorly and require preformed vitamin A in their diet; absorption is fat‑dependent and excessive intake is uncommon but may cause harmless orange discoloration of the skin or fur.
03
Vitamin D
Vitamin D is a fat‑soluble nutrient commonly added to pet foods to promote calcium and phosphorus absorption, supporting bone growth, neuromuscular function and immune health; commercial diets typically provide vitamin D3 (cholecalciferol) because dogs and cats rely on dietary sources rather than sunlight. Adequate dietary vitamin D prevents rickets and helps maintain bone health, but excess accumulates in the body and can cause hypercalcemia and organ damage, so levels are tightly regulated and additional supplementation should only be given under veterinary guidance.
04
Cholecalciferol
Cholecalciferol (vitamin D3) is used in pet foods as a vitamin supplement to support calcium and phosphorus metabolism, bone growth, and overall skeletal health in dogs and cats, which have limited ability to synthesize vitamin D from sunlight and therefore rely on dietary sources. While essential for proper mineral balance and immune function, cholecalciferol has a narrow therapeutic window and can be toxic in overdose, so formulations must be accurately dosed and owners should avoid additional unsupervised supplementation or exposure to cholecalciferol-containing rodenticides.
05
Vitamin E
Vitamin E is a fat‑soluble vitamin and antioxidant commonly added to dog and cat foods both as an essential nutrient and to protect fats and fat‑soluble vitamins from oxidation. It supports immune function, healthy skin and coat, and cellular protection; deficiency is uncommon in complete diets, while excessive supplemental doses are unnecessary and very high amounts may interfere with blood clotting or interact with certain medications.
