Apex Vitamin B12 is a sublingual B12. Some people do have trouble absorbing B12 from food or maybe don’t get enough because of a vegetarian diet, for example. A typical pattern is macrocytic anemia meaning the blood cells get large but don’t have adequate quantities of hemoglobin.
One common symptom is fatigue. We also recommend anyone having any brain issue to take this Vitamin B12 but not for the acutal B12 but for the methyl donors inherent in the vitamin that your brain needs to make neurotransmitters.
Vitamin B12 (K34) contains high potency B12 and is useful for vitamin B12 augmentation.* It provides more than 10 times the recommended daily value of vitamin B12 (in K34 – 300 mcg/serving, 5000% DV; in K56 – 1 mg/serving, 16,667% DV). This product utilizes a liquid form of vitamin B12–containing methylcobalamin dissolved in a bioavailable solution to support vitamin B12–deficient individuals.* Practitioner consultation required. https://popularvitamin.com/apex-energetics-vitamin-b12-drops-liquid-k34-1-oz.html
