A 20 pound dog needs a weight-based Benadryl dose set by a vet, after checking product strength and your dog’s health history.

For most healthy adults, standard oral Benadryl dosing is 25–50 mg every 4–6 hours, with a daily limit of 300 mg from all products.

Typical oral dosing is 1 mg of diphenhydramine per pound, so a healthy 10 pound dog often takes about 10 mg every 8–12 hours with vet guidance.

Benadryl dosage for dogs by weight is around 1 mg per pound, using plain diphenhydramine and only under direct veterinary guidance.

For an 18-month-old, diphenhydramine should only be given when a pediatrician confirms the right weight-based dose for your child.

A typical 70 pound dog can often take about 70 mg of plain diphenhydramine per dose, but a veterinarian should confirm the exact amount first.

Small daily servings of beetroot juice or cooked beetroot may help lower blood pressure, but safe amounts depend on your health and medicines.

Most adults do well with a daily beetroot supplement that delivers about 300–500 mg of nitrate, adjusted to health status and product label.

Most adults do well with about ½–1 cup of cooked beets a day, or 1–2 small beets, as part of their regular vegetable intake.

Most healthy adults do well with about half to one cup of cooked beets or a small glass of beet juice each day as part of a varied diet.
